openstack完整的部署(最详细)
一:keystone组件部署
只在控制节点上面操作
1、安装和配置keystone
# 1.安装keystone软件包 # wsgi:使web服务器支持WSGI的插件 # httpd:Apache软件包 # openstack-keystone:keystone的软件包 [root@controller ~]# yum install -y openstack-keystone httpd mod_wsgi # 查看keystone用户信息 [root@controller ~]# cat /etc/passwd | grep keystone keystone:x:163:163:OpenStack Keystone Daemons:/var/lib/keystone:/sbin/nologin # 查看keystone用户组 [root@controller ~]# cat /etc/group | grep keystone keystone:x:163: # 2.创建keystone的数据库并授权 [root@controller ~]# mysql -uroot -p000000 # 创建数据库 MariaDB [(none)]> CREATE DATABASE keystone; Query OK, 1 row affected (0.000 sec) # 授权本地登录keystone用户 MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.001 sec) # 授权任意远程主机登录keystone用户 MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.000 sec) # 退出数据库 MariaDB [(none)]> quit Bye # 3.修改keystone配置文件 [root@controller ~]# vi /etc/keystone/keystone.conf # 找到[database] 部分,加入如下内容,配置数据库连接信息 connection=mysql+pymysql://keystone:000000@controller/keystone # 找到[token] 部分,解开注释,配置令牌的加密方式 provider = fernet # 4.初始化keytone数据库 # 同步数据库 # su keytone:表示切换到keytone用户 # '-s /bin/sh':表示指定使用什么编译器来执行命令 # '-c':表示具体执行的命令 [root@controller ~]# su keystone -s /bin/sh -c "keystone-manage db_sync" # 检查数据库 [root@controller ~]# mysql -uroot -p000000 # 打开keystone数据库 MariaDB [(none)]> use keystone; Reading table information for completion of table and column names You can turn off this feature to get a quicker startup with -A Database changed # 显示keytone数据库中的数据表 MariaDB [keystone]> show tables; +------------------------------------+ | Tables_in_keystone | +------------------------------------+ | access_rule | | access_token | | application_credential | | application_credential_access_rule | | application_credential_role | # 出现如上所示的很多数据表,说明数据库同步成功。
2、keystone组件初始化
# 1.初始化Fernet密钥库 [root@controller ~]# keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone # 执行命令后创建/etc/keystone/fernet-keys,并在目录中生成两个fernet密钥,分别用于加密和解密 [root@controller fernet-keys]# pwd /etc/keystone/fernet-keys [root@controller fernet-keys]# du -sh * 4.0K 0 4.0K 1 [root@controller keystone]# keystone-manage credential_setup --keystone-user keystone --keystone-group keystone # 执行命令后创建/etc/keystone/credential-keys目录,生成两个fetnet密钥,用于加密/解密用户凭证 [root@controller credential-keys]# pwd /etc/keystone/credential-keys [root@controller credential-keys]# du -sh * 4.0K 0 4.0K 1 # 2.初始化用户身份认证信息 # openstack默认有一个admin用户,还没有对应的密码等登录所必须的信息。使用 `keystone-manage bootstrap` 初始化登录凭证。 [root@controller ~]# keystone-manage bootstrap --bootstrap-password 000000 \ # 设置密码 > --bootstrap-admin-url http://controller:5000/v3 \ # 设置用户服务端点 > --bootstrap-internal-url http://controller:5000/v3 \ # 设置内部用户的服务端点 > --bootstrap-public-url http://controller:5000/v3 \ # 设置公共用户的服务端点 > --bootstrap-region-id RegionOne # 设置区域ID # 命令执行后,keystone数据库中就已经存放了登录需要的验证信息。 # 3.配置web服务 # (1)给apache增加wsgi支持 # 将wsgi-keystone.conf文件软链接到'/etc/httpd/conf.d/目录',作为apache的配置文件 [root@controller ~]# ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/ [root@controller ~]# ls /etc/httpd/conf.d/ autoindex.conf README userdir.conf welcome.conf wsgi-keystone.conf # (2)修改apache服务器配置并启动 [root@controller ~]# vi /etc/httpd/conf/httpd.conf # 修改为web服务所在的IP地址或域名 96 ServerName controller # (3)启动apache [root@controller ~]# systemctl start httpd [root@controller ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service.
3、模拟登录验证
# 创建一个文件存储身份凭证 [root@controller ~]# vi admin-login export OS_USERNAME=admin export OS_PASSWORD=000000 export OS_PROJECT_NAME=admin export OS_USER_DOMAIN_NAME=Default export OS_PROJECT_DOMAIN_NAME=Default export OS_AUTH_URL=http://controller:5000/v3 export OS_IDENTITY_API_VERSION=3 export OS_IMAGE_API_VERSION=2 # 导入环境变量 [root@controller ~]# source admin-login # 查看现有环境信息 [root@controller ~]# export -p declare -x OS_AUTH_URL="http://controller:5000/v3" declare -x OS_IDENTITY_API_VERSION="3" declare -x OS_IMAGE_API_VERSION="2" declare -x OS_PASSWORD="000000" declare -x OS_PROJECT_DOMAIN_NAME="Default"/ declare -x OS_PROJECT_NAME="admin" declare -x OS_USERNAME="admin" declare -x OS_USER_DOMAIN_NAME="Default"
4、检测keystone服务
# 在default域创建名为 'project' 的项目 [root@controller ~]# openstack project create --domain default project +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | | | domain_id | default | | enabled | True | | id | e3a549077f354998aa1a75677cfde62e | | is_domain | False | | name | project | | options | {} | | parent_id | default | | tags | [] | +-------------+----------------------------------+ # 查看现有项目列表 [root@controller ~]# openstack project list +----------------------------------+---------+ | ID | Name | +----------------------------------+---------+ | 4188570a34464b938ed3fa7e08681df8 | admin | | e3a549077f354998aa1a75677cfde62e | project | +----------------------------------+---------+ # 创建名为user的角色 [root@controller ~]# openstack role create user +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | None | | domain_id | None | | id | 700ec993d3cf456fa591c03e72f37856 | | name | user | | options | {} | +-------------+----------------------------------+ # 查看当前角色列表 [root@controller ~]# openstack role list +----------------------------------+--------+ | ID | Name | +----------------------------------+--------+ | 47670bbd6cc1472ab42db560637c7ebe | reader | | 5eee0910aeb844a1b82f48100da7adc9 | admin | | 700ec993d3cf456fa591c03e72f37856 | user | | bc2c8147bbd643629a020a6bd9591eca | member | +----------------------------------+--------+ # 查看现有域列表 [root@controller ~]# openstack domain list +---------+---------+---------+--------------------+ | ID | Name | Enabled | Description | +---------+---------+---------+--------------------+ | default | Default | True | The default domain | +---------+---------+---------+--------------------+ # 查看现有用户列表 [root@controller ~]# openstack user list +----------------------------------+-------+ | ID | Name | +----------------------------------+-------+ | f4f16d960e0643d7b5a35db152c87dae | admin | +----------------------------------+-------+
二:glacne部署
安装openstack镜像服务,只在控制节点进行操作
1、安装glance
# 1.安装glance软件包 # 原生的源缺包,把阿里的源下载到这个路径 [root@controller yum.repos.d]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo [root@controller ~]# yum install -y openstack-glance # 安装后会自动生成glance用户和用户组 [root@controller ~]# cat /etc/passwd | grep glance glance:x:161:161:OpenStack Glance Daemons:/var/lib/glance:/sbin/nologin [root@controller ~]# cat /etc/group | grep glance glance:x:161: # 2.创建glance数据库并授权 # 连接数据库 [root@controller ~]# mysql -uroot -p000000 # 新建glance数据库 MariaDB [(none)]> CREATE DATABASE glance; Query OK, 1 row affected (0.001 sec) # 为新数据库授权本地和远程登录glance用户 MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.001 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.001 sec) # 退出数据库 MariaDB [(none)]> quit Bye
2、配置glance
glacne的配置文件是/etc/glance/glance-api.conf,修改可以实现glacne与数据库及keystone的连接
# 1.备份配置文件 [root@controller ~]# cp /etc/glance/glance-api.conf /etc/glance/glance-api.conf.bak # 2.去掉配置文件注释和空行 # grep:查找文件中符合条件的字符串。 -E:采用正则表达式;-v:匹配所有不满足正则的条件(反选) # ^:以什么开头; $:匹配字符结尾;|:匹配|左或|右的字符 [root@controller ~]# grep -Ev '^$|#' /etc/glance/glance-api.conf.bak > /etc/glance/glance-api.conf # 3.编辑配置文件 # default_store = file:默认存储系统为本地系统 # filesystem_store_datadir = /var/lib/glance/images/ : 镜像文件实际存储的目录 [root@controller ~]# vi /etc/glance/glance-api.conf [database] connection = mysql+pymysql://glance:000000@controller/glance [glance_store] stores = file default_store = file filesystem_store_datadir = /var/lib/glance/images/ [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password username = glance password = 000000 project_name = project user_domain_name = Default project_domain_name = Default [paste_deploy] flavor = keystone # 4.初始化数据库 # 同步数据库:将安装文件中的数据库表信息填入数据库中 [root@controller ~]# su glance -s /bin/sh -c "glance-manage db_sync" # 检查数据库 [root@controller ~]# mysql -uroot -p000000 MariaDB [(none)]> use glance MariaDB [glance]> show tables; +----------------------------------+ | Tables_in_glance | +----------------------------------+ | alembic_version | | image_locations | | image_members | | image_properties | | image_tags | | images | .....
3、glance组件初始化
glance安装配置成功后,需要给glance初始化用户,密码并分配角色,初始化服务和服务端点
(1)创建glance用户并分配角色
# 导入环境变量模拟登录 [root@controller ~]# source admin-login # 在default域创建名为glance,密码为000000的用户 [root@controller ~]# openstack user create --domain default --password 000000 glance +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 81238b556a444c8f80cb3d7dc72a24d3 | | name | glance | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+ # 查看当前已有的项目 [root@controller ~]# openstack project list +----------------------------------+---------+ | ID | Name | +----------------------------------+---------+ | 4188570a34464b938ed3fa7e08681df8 | admin | | e3a549077f354998aa1a75677cfde62e | project | +----------------------------------+---------+ # 查看已有的用户 [root@controller ~]# openstack user list +----------------------------------+--------+ | ID | Name | +----------------------------------+--------+ | f4f16d960e0643d7b5a35db152c87dae | admin | | 81238b556a444c8f80cb3d7dc72a24d3 | glance | +----------------------------------+--------+ # 授予glance用户操作project项目时的admin角色权限 [root@controller ~]# openstack role add --project project --user glance admin # 查看glance用户详情 [root@controller ~]# openstack user show glance +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 81238b556a444c8f80cb3d7dc72a24d3 | | name | glance | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+
(2)创建glacne服务及服务端点
# 1.创建服务 # 创建名为glance,类型为image的服务 [root@controller ~]# openstack service create --name glance image +---------+----------------------------------+ | Field | Value | +---------+----------------------------------+ | enabled | True | | id | 324a07034ea4453692570e3edf73cf2c | | name | glance | | type | image | +---------+----------------------------------+ # 2.创建镜像服务端点 # 服务端点有三种:公共用户(public)、内部组件(internal)、Admin用户(admin)服务的地址。 # 创建公共用户访问服务端点 [root@controller ~]# openstack endpoint create --region RegionOne glance public http://controller:9292 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | ab3208eb36fd4a8db9c90b9113da9bbb | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 324a07034ea4453692570e3edf73cf2c | | service_name | glance | | service_type | image | | url | http://controller:9292 | +--------------+----------------------------------+ # 创建内部组件访问服务端点 [root@controller ~]# openstack endpoint create --region RegionOne glance internal http://controller:9292 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 54994f15e8184e099334760060b9e2a9 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 324a07034ea4453692570e3edf73cf2c | | service_name | glance | | service_type | image | | url | http://controller:9292 | +--------------+----------------------------------+ # 创建Admin用户访问服务端点 [root@controller ~]# openstack endpoint create --region RegionOne glance admin http://controller:9292 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 97ae61936255471f9f55858cc0443e61 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 324a07034ea4453692570e3edf73cf2c | | service_name | glance | | service_type | image | | url | http://controller:9292 | +--------------+----------------------------------+ # 查克服务端点 [root@controller ~]# openstack endpoint list +----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+ | ID | Region | Service Name | Service Type | Enabled | Interface | URL | +----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+ | 0d31919afb564c8aa52ec5eddf474a55 | RegionOne | keystone | identity | True | admin | http://controller:5000/v3 | | 243f1e7ace4f444cba2978b900aeb165 | RegionOne | keystone | identity | True | internal | http://controller:5000/v3 | | 54994f15e8184e099334760060b9e2a9 | RegionOne | glance | image | True | internal | http://controller:9292 | | 702df46845be40fb9e75fb988314ee90 | RegionOne | keystone | identity | True | public | http://controller:5000/v3 | | 97ae61936255471f9f55858cc0443e61 | RegionOne | glance | image | True | admin | http://controller:9292 | | ab3208eb36fd4a8db9c90b9113da9bbb | RegionOne | glance | image | True | public | http://controller:9292 | +----------------------------------+-----------+--------------+--------------+---------+-----------+---------------------------+
(3)启动glacne服务
# 开机启动glance服务 [root@controller ~]# systemctl enable openstack-glance-api Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-glance-api.service to /usr/lib/systemd/system/openstack-glance-api.service. # 启动glance服务 [root@controller ~]# systemctl start openstack-glance-api
4、验证glacne服务
# 方法一:查看端口占用情况(9292是否被占用) [root@controller ~]# netstat -tnlup | grep 9292 tcp 0 0 0.0.0.0:9292 0.0.0.0:* LISTEN 5740/python2 # 方法二:查看服务运行状态(active (running)说明服务正在运行) [root@controller ~]# systemctl status openstack-glance-api ● openstack-glance-api.service - OpenStack Image Service (code-named Glance) API server Loaded: loaded (/usr/lib/systemd/system/openstack-glance-api.service; enabled; vendor preset: disabled) Active: active (running) since Wed 2022-10-19 17:09:13 CST;
5、用glacne制作镜像
# 安装lrzsz工具 [root@controller ~]# yum install -y lrzsz # 上传cirros-0.5.1-x86_64-disk.img 到/root目录 [root@controller ~]# rz z waiting to receive.**B0100000023be50 [root@controller ~]# ls admin-login cirros-0.5.1-x86_64-disk.img # glance创建镜像 [root@controller ~]# openstack image create --file cirros-0.5.1-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros # 查看镜像列表 [root@controller ~]# openstack image list +--------------------------------------+--------+--------+ | ID | Name | Status | +--------------------------------------+--------+--------+ | a859fddb-3ec1-4cd8-84ec-482112af929b | cirros | active | +--------------------------------------+--------+--------+ # 删除镜像 [root@controller ~]# openstack image delete a859fddb-3ec1-4cd8-84ec-482112af929b # 重新创镜像 [root@controller ~]# openstack image create --file cirros-0.5.1-x86_64-disk.img --disk-format qcow2 --container-format bare --public cirros +------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | Field | Value | +------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ | checksum | 1d3062cd89af34e419f7100277f38b2b | | container_format | bare | | created_at | 2022-10-19T09:20:03Z | | disk_format | qcow2 | | file | /v2/images/7096885c-0a58-4086-8014-b92affceb0e8/file | | id | 7096885c-0a58-4086-8014-b92affceb0e8 | | min_disk | 0 | | min_ram | 0 | | name | cirros | | owner | 4188570a34464b938ed3fa7e08681df8 | | properties | os_hash_algo='sha512', os_hash_value='553d220ed58cfee7dafe003c446a9f197ab5edf8ffc09396c74187cf83873c877e7ae041cb80f3b91489acf687183adcd689b53b38e3ddd22e627e7f98a09c46', os_hidden='False' | | protected | False | | schema | /v2/schemas/image | | size | 16338944 | | status | active | | tags | | | updated_at | 2022-10-19T09:20:03Z | | virtual_size | None | | visibility | public | +------------------+--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------+ # 查看镜像物理文件 # /var/lib/glance/images/文件夹是 glance-api.conf配置文件中定义镜像文件存储的位置。 [root@controller ~]# ll /var/lib/glance/images/ total 15956 -rw-r----- 1 glance glance 16338944 Oct 19 17:20 7096885c-0a58-4086-8014-b92affceb0e8
三:放置服务(placement)部署
从stein版本开始,将系统资源的监控功能从nova中独立出来,成为一个独立的组件
1、安装placement软件包
# 安装placement软件包 # 安装好会自动生成placement用户和用户组 [root@controller ~]# yum install -y openstack-placement-api # 查看确认用户和用户组已经创建 [root@controller ~]# cat /etc/passwd | grep placement placement:x:993:990:OpenStack Placement:/:/bin/bash [root@controller ~]# cat /etc/group | grep placement placement:x:990: # 登录数据库 [root@controller ~]# mysql -uroot -p000000 # 创建placement数据库 MariaDB [(none)]> create database placement; Query OK, 1 row affected (0.000 sec) # 数据库授权 MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.001 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.000 sec) MariaDB [(none)]> quit Bye
2、配置placement服务
# 备份配置文件 [root@controller ~]# cp /etc/placement/placement.conf /etc/placement/placement.conf.bak [root@controller ~]# ls /etc/placement/ placement.conf placement.conf.bak policy.json # 去掉配置文件注释和空行 [root@controller ~]# grep -Ev '^$|#' /etc/placement/placement.conf.bak > /etc/placement/placement.conf [root@controller ~]# cat /etc/placement/placement.conf [DEFAULT] [api] [cors] [keystone_authtoken] [oslo_policy] [placement] [placement_database] [profiler] # 编辑配置文件 [root@controller ~]# vi /etc/placement/placement.conf [api] auth_strategy = keystone [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = project username = placement password = 000000 [placement_database] connection = mysql+pymysql://placement:000000@controller/placement # 编辑修改apache配置文件 # 在"VirtualHost"节点加入如下 Directory内容 [root@controller ~]# vi /etc/httpd/conf.d/00-placement-api.conf Listen 8778 <VirtualHost *:8778> WSGIProcessGroup placement-api ...略 <Directory /usr/bin> <IfVersion >= 2.4> Require all granted </IfVersion> </Directory> </VirtualHost> # 查看Apache版本号 [root@controller ~]# httpd -v Server version: Apache/2.4.6 (CentOS) Server built: Jan 25 2022 14:08:43 # 同步数据库,将数据库的表信息填充进数据库 [root@controller ~]# su placement -s /bin/sh -c "placement-manage db sync" # 检查数据库同步 [root@controller ~]# mysql -uroot -p000000 MariaDB [(none)]> use placement; MariaDB [placement]> show tables; +------------------------------+ | Tables_in_placement | +------------------------------+ | alembic_version | | allocations | | consumers | | inventories | | placement_aggregates | | projects | | resource_classes | | resource_provider_aggregates | | resource_provider_traits | | resource_providers | | traits | | users | +------------------------------+ 12 rows in set (0.000 sec)
3、placement组件初始化
# 导入环境变量模拟登录 [root@controller ~]# source admin-login # 创建placement用户 [root@controller ~]# openstack user create --domain default --password 000000 placement +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | e0d6a46f9b1744d8a7ab0332ab45d59c | | name | placement | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+ # 给placement用户分配admin角色 [root@controller ~]# openstack role add --project project --user placement admin # 创建placement服务 [root@controller ~]# openstack service create --name placement placement +---------+----------------------------------+ | Field | Value | +---------+----------------------------------+ | enabled | True | | id | da038496edf04ce29d7d3d6b8e647755 | | name | placement | | type | placement | +---------+----------------------------------+ # 查看当前已经创建的服务列表 [root@controller ~]# openstack service list +----------------------------------+-----------+-----------+ | ID | Name | Type | +----------------------------------+-----------+-----------+ | 324a07034ea4453692570e3edf73cf2c | glance | image | | 5d25b4ed1443497599707e043866eaae | keystone | identity | | da038496edf04ce29d7d3d6b8e647755 | placement | placement | +----------------------------------+-----------+-----------+ # 创建服务端点 # placement服务端点有三个:公众用户、内部组件、Admin用户(admin)服务。 [root@controller ~]# openstack endpoint create --region RegionOne placement public http://controller:8778 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | da0c279c9a394d0f80e7a33acb9e0d8d | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | da038496edf04ce29d7d3d6b8e647755 | | service_name | placement | | service_type | placement | | url | http://controller:8778 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne placement internal http://controller:8778 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 79ca63ffd52d4d96b418cdf962c1e3ca | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | da038496edf04ce29d7d3d6b8e647755 | | service_name | placement | | service_type | placement | | url | http://controller:8778 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne placement admin http://controller:8778 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | fbee454f73d64bb18a52d8696c7aa596 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | da038496edf04ce29d7d3d6b8e647755 | | service_name | placement | | service_type | placement | | url | http://controller:8778 | +--------------+----------------------------------+ # 查看检查 [root@controller ~]# openstack endpoint list
4、placement组件检测
(1)检测placement组件的运行状态的2种方法

四:计算服务nova部署
nova负责云主机实例的创建,删除,启动,停止等
1、安装配置控制节点nova服务
(1)安装nova软件包
# 安装nova相关软件包 [root@controller ~]# yum install -y openstack-nova-api openstack-nova-conductor openstack-nova-scheduler openstack-nova-novncproxy # 查看nova用户 [root@controller ~]# cat /etc/passwd | grep nova nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/sbin/nologin # 查看nova用户组 [root@controller ~]# cat /etc/group | grep nova nobody:x:99:nova nova:x:162:nova
(2)创建nova数据库并授权
支持nova组件的数据库有三个:nova_api,nova_cell0,nova
# 登录数据库 [root@controller ~]# mysql -uroot -p000000 # 创建三个数据库 MariaDB [(none)]> create database nova_api; MariaDB [(none)]> create database nova_cell0; MariaDB [(none)]> create database nova; MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | nova | | nova_api | | nova_cell0 | # 为数据库授权本地和远程管理权限 MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '000000'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '000000'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '000000'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '000000'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '000000'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '000000';
(3)修改nova配置文件
nova配置文件,/etc/nova/nova.conf。修改这个文件可以实现nova与数据库,keystone和其他组件的连接
api_database:配置与数据库nova_api连接
database:配置与数据库nova连接
api、keystone_authtoken:配置与keystone交互
placement:配置与placement组件交互
glance:配置glacne组件交互
oslo_concurrency:配置锁的路径,为openstack中的代码提供线程及进程锁,lock_path配置这个模块指定的路径
DEFAULT:配置使用消息队列和防火墙等信息
VNC:配置vnc连接模式
配置文件中的$表示取变量值
# 备份配置文件 [root@controller ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak # 去除配置文件中的注释和空行 [root@controller ~]# grep -Ev '^$|#' /etc/nova/nova.conf.bak > /etc/nova/nova.conf # 修改配置文件 [root@controller ~]# vi /etc/nova/nova.conf [DEFAULT] enable_apis = osapi_compute,metadata transport_url = rabbit://rabbitmq:000000@controller:5672 my_ip = 192.168.10.10 use_neutron = true firewall_driver = nova.virt.firewall.NoopFirewallDriver [api] auth_strategy = keystone [api_database] connection = mysql+pymysql://nova:000000@controller/nova_api [database] connection = mysql+pymysql://nova:000000@controller/nova [glance] api_servers = http://controller:9292 [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = project username = nova password = 000000 [oslo_concurrency] lock_path = /var/lib/nova/tmp [placement] auth_url = http://controller:5000 auth_type = password project_domain_name = Default user_domain_name = Default project_name = project username = placement password = 000000 region_name = RegionOne [vnc] enabled = true server_listen = $my_ip server_proxyclient_address = $my_ip
(4)初始化数据库
将安装文件中的数据库表信息填入数据库中
# 初始化 nova_api数据库 [root@controller ~]# su nova -s /bin/sh -c "nova-manage api_db sync" # 创建‘cell1’单元,该单元使用nova数据库 [root@controller ~]# su nova -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1" # 映射nova 到cell0数据库,使cell0的表结构与nova表结构一致 [root@controller ~]# su nova -s /bin/sh -c "nova-manage cell_v2 map_cell0" # 初始化nova数据库,因为映射,cell0会同步创建相同数据库(有warning先忽略) [root@controller ~]# su nova -s /bin/sh -c "nova-manage db sync"
(5)验证单元是否都正确注册
存在cell0和cell2个单元则正常
cell0:系统管理
cell1:云主机管理,每增加一个计算计算节点则增加一个和cell1功能相同的单元
[root@controller ~]# nova-manage cell_v2 list_cells +-------+--------------------------------------+----------------------------------------+-------------------------------------------------+----------+ | Name | UUID | Transport URL | Database Connection | Disabled | +-------+--------------------------------------+----------------------------------------+-------------------------------------------------+----------+ | cell0 | 00000000-0000-0000-0000-000000000000 | none:/ | mysql+pymysql://nova:****@controller/nova_cell0 | False | | cell1 | 83ad6d17-f245-4310-8729-fccaa033edf2 | rabbit://rabbitmq:****@controller:5672 | mysql+pymysql://nova:****@controller/nova | False | +-------+--------------------------------------+----------------------------------------+-------------------------------------------------+----------+
2、控制节点nova组件初始化及检测
(1)nova组件初始化
# 导入环境变量模拟登录 [root@controller ~]# source admin-login # 在default域创建名为nova的用户 [root@controller ~]# openstack user create --domain default --password 000000 nova +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 2f5041ed122d4a50890c34ea02881b47 | | name | nova | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+ # 为nova用户分配admin角色 [root@controller ~]# openstack role add --project project --user nova admin # 创建compute类型的nova服务 [root@controller ~]# openstack service create --name nova compute +---------+----------------------------------+ | Field | Value | +---------+----------------------------------+ | enabled | True | | id | e7cccf0a4d2549139801ac51bb8546db | | name | nova | | type | compute | +---------+----------------------------------+ # 创建服务端点 [root@controller ~]# openstack endpoint create --region RegionOne nova public http://controller:8774/v2.1 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | c60a9641abbb47b391751c9a0b0d6828 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | e7cccf0a4d2549139801ac51bb8546db | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2.1 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne nova internal http://controller:8774/v2.1 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 49b042b01ad44784888e65366d61dede | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | e7cccf0a4d2549139801ac51bb8546db | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2.1 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 6dd22acff2ab4c2195cefee39f371cc0 | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | e7cccf0a4d2549139801ac51bb8546db | | service_name | nova | | service_type | compute | | url | http://controller:8774/v2.1 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint list | grep nova | 49b042b01ad44784888e65366d61dede | RegionOne | nova | compute | True | internal | http://controller:8774/v2.1 | | 6dd22acff2ab4c2195cefee39f371cc0 | RegionOne | nova | compute | True | admin | http://controller:8774/v2.1 | | c60a9641abbb47b391751c9a0b0d6828 | RegionOne | nova | compute | True | public | http://controller:8774/v2.1 | # 开机启动控制节点的nova服务 [root@controller ~]# systemctl enable openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-api.service to /usr/lib/systemd/system/openstack-nova-api.service. Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-scheduler.service to /usr/lib/systemd/system/openstack-nova-scheduler.service. Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-conductor.service to /usr/lib/systemd/system/openstack-nova-conductor.service. Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-novncproxy.service to /usr/lib/systemd/system/openstack-nova-novncproxy.service. # 启动nova服务 [root@controller ~]# systemctl start openstack-nova-api openstack-nova-scheduler openstack-nova-conductor openstack-nova-novncproxy
(2)检测控制节点nova服务
nova服务会占用8874和9775端口,查看端口是否启动,可判断nova服务是否已经运行了
nova-conductor和nova-scheduler2个服务在控制节点的模块均处于up状态,则服务正常
# 方法一:查看端口占用 [root@controller ~]# netstat -nutpl | grep 877 tcp 0 0 0.0.0.0:8774 0.0.0.0:* LISTEN 2487/python2 tcp 0 0 0.0.0.0:8775 0.0.0.0:* LISTEN 2487/python2 tcp6 0 0 :::8778 :::* LISTEN 1030/httpd # 方法二:查看计算服务列表 [root@controller ~]# openstack compute service list +----+----------------+------------+----------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+----------------+------------+----------+---------+-------+----------------------------+ | 1 | nova-conductor | controller | internal | enabled | up | 2022-10-28T10:53:26.000000 | | 4 | nova-scheduler | controller | internal | enabled | up | 2022-10-28T10:53:28.000000 | +----+----------------+------------+----------+---------+-------+----------------------------+
3、安装配置计算节点nova服务
nova需要再计算节点安装nova-compute计算模块,所有的云主机均为该模块在计算节点生成
(1)安装nova软件包
# 把阿里云的源下载过来 [root@compute yum.repos.d]# scp [email protected]:/etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/ [email protected]'s password: CentOS-Base.repo 100% 2523 1.1MB/s 00:00 [root@compute yum.repos.d]# ls CentOS-Base.repo OpenStack.repo repo.bak # 安装nova的计算模块 [root@compute yum.repos.d]# yum install -y openstack-nova-compute # 查看用户信息 [root@compute ~]# cat /etc/passwd | grep nova nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/sbin/nologin # 查看用户组信息 [root@compute ~]# cat /etc/group | grep nova nobody:x:99:nova qemu:x:107:nova libvirt:x:987:nova nova:x:162:nova
(2)修改nova配置文件
nova的配置文件/etc/nova/nova.conf,修改他实现nova与数据库,keystone和其他组件的连接
与控制节点的主要区别:
my_ip = 192.168.109.10
libvirt中多了配置:virt_type = qemu
# 备份配置文件 [root@compute ~]# cp /etc/nova/nova.conf /etc/nova/nova.conf.bak # 去掉配置文件注释和空行 [root@compute ~]# grep -Ev '^$|#' /etc/nova/nova.conf.bak > /etc/nova/nova.conf # 编辑配置文件 [root@compute ~]# vi /etc/nova/nova.conf [DEFAULT] enable_apis = osapi_compute,metadata transport_url = rabbit://rabbitmq:000000@controller:5672 my_ip = 192.168.10.20 use_neutron = true firewall_driver = nova.virt.firewall.NoopFirewallDriver [api] auth_strategy = keystone [glance] api_servers = http://controller:9292 [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = project username = nova password = 000000 [libvirt] virt_type = qemu [oslo_concurrency] lock_path = /var/lib/nova/tmp [placement] auth_url = http://controller:5000 auth_type = password project_domain_name = Default user_domain_name = Default project_name = project username = placement password = 000000 region_name = RegionOne [vnc] enabled = true server_listen = 0.0.0.0 server_proxyclient_address = $my_ip novncproxy_base_url = http://192.168.10.10:6080/vnc_auto.html
(3)启动计算节点nova服务
# 开机启动 [root@compute ~]# systemctl enable libvirtd openstack-nova-compute Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-nova-compute.service to /usr/lib/systemd/system/openstack-nova-compute.service. # 启动 [root@compute ~]# systemctl start libvirtd openstack-nova-compute # 在控制节点查看服务状态 [root@controller ~]# openstack compute service list +----+----------------+------------+----------+---------+-------+----------------------------+ | ID | Binary | Host | Zone | Status | State | Updated At | +----+----------------+------------+----------+---------+-------+----------------------------+ | 1 | nova-conductor | controller | internal | enabled | up | 2022-10-28T11:19:57.000000 | | 4 | nova-scheduler | controller | internal | enabled | up | 2022-10-28T11:19:49.000000 | | 6 | nova-compute | compute | nova | enabled | up | 2022-10-28T11:19:56.000000 | +----+----------------+------------+----------+---------+-------+----------------------------+
4、发现计算节点并检验服务
每个计算节点要加入系统,都需要在控制节点上执行一次发现计算节点的操作,被发现的计算节点才能被映射为一个单元
(1)发现计算节点
注意是控制节点操作
# 模拟登录验证 [root@controller ~]# source admin-login # 切换nova用户执行发现未注册计算节点 # 发现计算节点后,将自动与cell1单元形成关联,后面可通过cell1对计算节点管理 [root@controller ~]# su nova -s /bin/sh -c "nova-manage cell_v2 discover_hosts --verbose" Found 2 cell mappings. Getting computes from cell 'cell1': 83ad6d17-f245-4310-8729-fccaa033edf2 Checking host mapping for compute host 'compute': 13af5106-c1c1-4b3f-93f5-cd25e030f39d Creating host mapping for compute host 'compute': 13af5106-c1c1-4b3f-93f5-cd25e030f39d Found 1 unmapped computes in cell: 83ad6d17-f245-4310-8729-fccaa033edf2 Skipping cell0 since it does not contain hosts. # 设置自动发现 # 1.每隔60秒执行一次发现命令 [root@controller ~]# vi /etc/nova/nova.conf [scheduler] discover_hosts_in_cells_interval = 60 # 2.重启nova-api服务,让配置生效 [root@controller ~]# systemctl restart openstack-nova-api
(2)验证nova服务
均在控制节点上操作

5、安装并完成情况检测
# 1.检查控制节点nova用户和用户组 [root@controller ~]# cat /etc/passwd | grep nova nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/sbin/nologin [root@controller ~]# cat /etc/group | grep nova nobody:x:99:nova nova:x:162:nova # 2.检查计算节点nova用户和用户组 [root@compute ~]# cat /etc/passwd | grep nova nova:x:162:162:OpenStack Nova Daemons:/var/lib/nova:/sbin/nologin [root@compute ~]# cat /etc/group | grep nova nobody:x:99:nova qemu:x:107:nova libvirt:x:987:nova nova:x:162:nova # 3.查看控制节点数据库 MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | glance | | information_schema | | keystone | | mysql | | nova | | nova_api | | nova_cell0 | # 4.查看nova用户对数据库的权限 MariaDB [(none)]> show grants for nova@'%'; +-----------------------------------------------------------------------------------------------------+ | Grants for nova@% | +-----------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'nova'@'%' IDENTIFIED BY PASSWORD '*032197AE5731D4664921A6CCAC7CFCE6A0698693' | | GRANT ALL PRIVILEGES ON `nova`.* TO 'nova'@'%' | | GRANT ALL PRIVILEGES ON `nova_api`.* TO 'nova'@'%' | | GRANT ALL PRIVILEGES ON `nova_cell0`.* TO 'nova'@'%' | +-----------------------------------------------------------------------------------------------------+ 4 rows in set (0.000 sec) MariaDB [(none)]> show grants for nova@'localhost'; +-------------------------------------------------------------------------------------------------------------+ | Grants for nova@localhost | +-------------------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'nova'@'localhost' IDENTIFIED BY PASSWORD '*032197AE5731D4664921A6CCAC7CFCE6A0698693' | | GRANT ALL PRIVILEGES ON `nova`.* TO 'nova'@'localhost' | | GRANT ALL PRIVILEGES ON `nova_cell0`.* TO 'nova'@'localhost' | | GRANT ALL PRIVILEGES ON `nova_api`.* TO 'nova'@'localhost' # 5.nova\nova_api\nova_cell0数据库表同步 MariaDB [(none)]> use nova Database changed MariaDB [nova]> show tables; +--------------------------------------------+ | Tables_in_nova | +--------------------------------------------+ | agent_builds | | aggregate_hosts | | aggregate_metadata | # 6.检查nova用户是否存在 [root@controller ~]# openstack user list +----------------------------------+-----------+ | ID | Name | +----------------------------------+-----------+ | f4f16d960e0643d7b5a35db152c87dae | admin | | 81238b556a444c8f80cb3d7dc72a24d3 | glance | | e0d6a46f9b1744d8a7ab0332ab45d59c | placement | | 2f5041ed122d4a50890c34ea02881b47 | nova | # 7.检查nova用户是否有admin权限 [root@controller ~]# openstack role list +----------------------------------+--------+ | ID | Name | +----------------------------------+--------+ | 47670bbd6cc1472ab42db560637c7ebe | reader | | 5eee0910aeb844a1b82f48100da7adc9 | admin | | 700ec993d3cf456fa591c03e72f37856 | user | | bc2c8147bbd643629a020a6bd9591eca | member | +----------------------------------+--------+ [root@controller ~]# openstack role assignment list +----------------------------------+----------------------------------+-------+----------------------------------+--------+--------+-----------+ | Role | User | Group | Project | Domain | System | Inherited | +----------------------------------+----------------------------------+-------+----------------------------------+--------+--------+-----------+ | 5eee0910aeb844a1b82f48100da7adc9 | 2f5041ed122d4a50890c34ea02881b47 | | e3a549077f354998aa1a75677cfde62e | | | False | # 8.检查是否创建看了服务实体nova [root@controller ~]# openstack service list +----------------------------------+-----------+-----------+ | ID | Name | Type | +----------------------------------+-----------+-----------+ | 324a07034ea4453692570e3edf73cf2c | glance | image | | 5d25b4ed1443497599707e043866eaae | keystone | identity | | da038496edf04ce29d7d3d6b8e647755 | placement | placement | | e7cccf0a4d2549139801ac51bb8546db | nova | compute | # 9.检查nova服务端点 [root@controller ~]# openstack endpoint list | grep nova | 49b042b01ad44784888e65366d61dede | RegionOne | nova | compute | True | internal | http://controller:8774/v2.1 | | 6dd22acff2ab4c2195cefee39f371cc0 | RegionOne | nova | compute | True | admin | http://controller:8774/v2.1 | | c60a9641abbb47b391751c9a0b0d6828 | RegionOne | nova | compute | True | public | http://controller:8774/v2.1 | # 10.nova服务是否正常运行 [root@controller ~]# nova-status upgrade check +--------------------------------+ | Upgrade Check Results | +--------------------------------+ | Check: Cells v2 | | Result: Success | | Details: None | +--------------------------------+ | Check: Placement API | | Result: Success | | Details: None | +--------------------------------+ | Check: Ironic Flavor Migration | | Result: Success | | Details: None | +--------------------------------+ | Check: Cinder API | | Result: Success | | Details: None | +--------------------------------+
五:网络服务(Neutron)部署
neutron负责虚拟网络设备的创建,管理,包含网桥,网络,端口等
1、网络初始环境准备
(1)设置外网网卡为混杂模式
需要将网卡设置为混杂模式,网卡能将通过自己的接口的所有数据都捕获,为了实现虚拟网络的数据转发,neutron需要将外网网卡设置为混杂模式
# 设置控制节点 [root@controller ~]# ifconfig ens34 promisc [root@controller ~]# ifconfig ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.10.10 netmask 255.255.255.0 broadcast 192.168.10.255 略... ens34: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500 《————这里增加了PROMISC # 设置计算节点 [root@compute ~]# ifconfig ens34 promisc [root@compute ~]# ifconfig ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 192.168.10.20 netmask 255.255.255.0 broadcast 192.168.10.255 略... ens34: flags=4419<UP,BROADCAST,RUNNING,PROMISC,MULTICAST> mtu 1500
网卡信息中出现了PROMISC字样,则表示陈工设置为混杂模式,凡是通过该网卡的数据均可被该网卡接收,
在设置开机后混杂模式自动生效
# 控制节点执行 [root@controller ~]# echo 'ifconfig ens34 promisc' >> /etc/profile [root@controller ~]# tail -1 /etc/profile ifconfig ens34 promisc # 计算节点执行 [root@compute ~]# echo 'ifconfig ens34 promisc' >> /etc/profile [root@compute ~]# tail -1 /etc/profile ifconfig ens34 promisc
(2)加载桥接模式防火墙模块
网络过滤器时linux内核中的一个软件框架,用于管理网络数据包,能网络地址转换,还能修改数据包,数据包过滤等
# 1.修改系统参数配置文件 # 控制节点修改 [root@controller ~]# echo 'net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-call-ip6tables = 1' >> /etc/sysctl.conf [root@controller ~]# tail -n 2 /etc/sysctl.conf net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-call-ip6tables = 1 # 计算节点修改 [root@compute ~]# echo 'net.bridge.bridge-nf-call-iptables = 1 > net.bridge.bridge-nf-call-ip6tables = 1' >> /etc/sysctl.conf [root@compute ~]# tail -n 2 /etc/sysctl.conf net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-call-ip6tables = 1 # 2.分别加载br_netfilter模块 [root@controller ~]# modprobe br_netfilter [root@compute ~]# modprobe br_netfilter # 3.分别检查模块加载 [root@controller ~]# sysctl -p net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-call-ip6tables = 1 [root@compute ~]# sysctl -p net.bridge.bridge-nf-call-iptables = 1 net.bridge.bridge-nf-call-ip6tables = 1
2、控制节点neutron服务安装配置
(1)安装neutron软件包
openstack-neutron:neuron-server的包
openstack-neutron-ml2:ml2插件的包
openstack-neutron-linuxbridge:网桥和网络提供者相关的包
# 安装相关软件包 # 阿里云上有包dnsmasq-utils-2.76-17.el7_9.3.x86_64.rpm缺失 [root@controller ~]# yum install -y wget [root@controller ~]# wget http://mirror.centos.org/centos/7/updates/x86_64/Packages/dnsmasq-utils-2.76-17.el7_9.3.x86_64.rpm [root@controller ~]# ls admin-login cirros-0.5.1-x86_64-disk.img dnsmasq-utils-2.76-17.el7_9.3.x86_64.rpm [root@controller ~]# rpm -ivh dnsmasq-utils-2.76-17.el7_9.3.x86_64.rpm Preparing... ################################# [100%] Updating / installing... 1:dnsmasq-utils-2.76-17.el7_9.3 ################################# [100%] [root@controller ~]# yum install -y openstack-neutron openstack-neutron-ml2 openstack-neutron-linuxbridge # 检查用户信息 [root@controller ~]# cat /etc/passwd | grep neutron neutron:x:990:987:OpenStack Neutron Daemons:/var/lib/neutron:/sbin/nologin # 检查用户组信息 [root@controller ~]# cat /etc/group | grep neutron neutron:x:987:
(2)创建neutron数据库并授权
# 1.登录并创建数据库 [root@controller ~]# mysql -uroot -p000000 MariaDB [(none)]> create database neutron; Query OK, 1 row affected (0.000 sec) MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | glance | | information_schema | | keystone | | mysql | | neutron | # 2.为数据库授权本地和远程管理权限 MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.001 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.000 sec)
(3)修改neutron服务相关的配置文件
1.配置neutron组件信息
修改default与keystone_autjoken部分,实现与keystone交互
修改database部分,实现与数据库连接
修改default部分,实现与消息队列交互及核心插件等
修改oslo_concurrency,配置锁路径
# 备份配置文件 [root@controller ~]# cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak # 去掉配置文件注释和空行 [root@controller ~]# grep -Ev '^$|#' /etc/neutron/neutron.conf.bak > /etc/neutron/neutron.conf # 编辑配置文件 [root@controller ~]# vi /etc/neutron/neutron.conf [DEFAULT] core_plugin = ml2 service_plugins = router transport_url = rabbit://rabbitmq:000000@controller auth_strategy = keystone notify_nova_on_port_status_changes = true notify_nova_on_port_data_changes = true [database] connection = mysql+pymysql://neutron:000000@controller/neutron [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = project username = neutron password = 000000 [oslo_concurrency] lock_path = /var/lib/nova/tmp [nova] auth_url = http://controller:5000 auth_type = password project_domain_name = default user_domain_name = default project_name = project username = nova password = 000000 region_name = RegionOne server_proxyclient_address = 192.168.10.10
2、修改二层模块插件(ml2plugin)的配置文件
是neutron的核心插件
# 备份配置文件 [root@controller ~]# cp /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugins/ml2/ml2_conf.ini.bak # 去除配置文件中的注释和空行 [root@controller ~]# grep -Ev '^$|#' /etc/neutron/plugins/ml2/ml2_conf.ini.bak > /etc/neutron/plugins/ml2/ml2_conf.ini # 编辑配置文件 [root@controller ~]# vi /etc/neutron/plugins/ml2/ml2_conf.ini [ml2] type_drivers = flat,local,vlan,gre,vxlan,geneve tenant_network_types = local,flat mechanism_drivers = linuxbridge extension_drivers = port_security [ml2_type_flat] flat_networks = provider [securitygroup] enable_ipset = true # 设置映射启用ML2插件 [root@controller ~]# ln -s /etc/neutron/plugins/ml2/ml2_conf.ini /etc/neutron/plugin.ini [root@controller ~]# ll /etc/neutron/ lrwxrwxrwx 1 root root 37 Nov 4 20:01 plugin.ini -> /etc/neutron/plugins/ml2/ml2_conf.ini
3、修改网桥代理配置文件
要在ml2的配置文件中设置机制驱动mechanism_drivers的值为linuxbridge
# 1.备份配置文件 [root@controller ~]# cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak # 2.删除注释和空行 [root@controller ~]# grep -Ev '^$|#' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak > /etc/neutron/plugins/ml2/linuxbridge_agent.ini [root@controller ~]# cat /etc/neutron/plugins/ml2/linuxbridge_agent.ini [DEFAULT] # 3.编辑配置文件 [root@controller ~]# vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini [DEFAULT] [linux_bridge] physical_interface_mappings = provider:ens34 [vxlan] enable_vxlan = false [securitygroup] enable_security_group = true firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
4、修改dhcp代理配置文件
dhcp-agent为云主机提供了自动分配ip地址的服务
# 1.备份和去除空行和注释配置文件 [root@controller ~]# cp /etc/neutron/dhcp_agent.ini /etc/neutron/dhcp_agent.ini.bak [root@controller ~]# grep -Ev '^$|#' /etc/neutron/dhcp_agent.ini.bak > /etc/neutron/dhcp_agent.ini [root@controller ~]# cat /etc/neutron/dhcp_agent.ini [DEFAULT] # 2.编辑配置文件 [root@controller ~]# vi /etc/neutron/dhcp_agent.ini [DEFAULT] interface_driver = linuxbridge dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq enable_isolated_metadata = true
5、修改元数据代理配置文件
云主机在计算节点,运行过程中需要和控制节点nova-api模块交互,交互需要使用neutron-metadata-agent
# 1.备份和去除空行注释配置文件 [root@controller ~]# cp /etc/neutron/metadata_agent.ini /etc/neutron/metadata_agent.ini.bak [root@controller ~]# grep -Ev '^$|#' /etc/neutron/metadata_agent.ini.bak > /etc/neutron/metadata_agent.ini [root@controller ~]# cat /etc/neutron/metadata_agent.ini [DEFAULT] [cache] # 2.编辑配置文件 [root@controller ~]# vi /etc/neutron/metadata_agent.ini [DEFAULT] nova_metadata_host = controller metadata_proxy_shared_secret = METADATA_SECRET [cache]
6、修改Nova配置文件
nova处于云平台的核心位置,需要在nova配置文件中指明如何与neutron进行交互
# 注意文件目录 [root@controller ~]# echo ' [neutron] auth_url = http://controller:5000 auth_type = password project_domain_name = Default user_domain_name = Default region_name = RegionOne project_name = project username = neutron password = 000000 service_metadata_proxy = true metadata_proxy_shared_secret = METADATA_SECRET ' >> /etc/nova/nova.conf
(4)初始化数据库
neutron数据库同步,将安装文件中的数据库的表信息填充到数据库中
# 数据库同步 [root@controller neutron]# su neutron -s /bin/sh -c "neutron-db-manage \ --config-file /etc/neutron/neutron.conf \ --config-file /etc/neutron/plugins/ml2/ml2_conf.ini upgrade head" # 数据库验证 [root@controller neutron]# mysql -uroot -p000000 MariaDB [(none)]> use neutron; Database changed MariaDB [neutron]> show tables; +-----------------------------------------+ | Tables_in_neutron | +-----------------------------------------+ | address_scopes | | agents | | alembic_version | | allowedaddresspairs | | arista_provisioned_nets | | arista_provisioned_tenants |
3、neutron组件初始化
任务均在控制节点完成
(1)创建neutron用户并分配角色
# 模拟登录 [root@controller ~]# source admin-login # 在 default 域创建neutron用户 [root@controller ~]# openstack user create --domain default --password 000000 neutron +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | 67bd1f9c48174e3e96bb41e0f76687ca | | name | neutron | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+ # 给neutron用户分配admin角色 [root@controller ~]# openstack role add --project project --user neutron admin # 验证 [root@controller ~]# openstack role assignment list +----------------------------------+----------------------------------+-------+----------------------------------+--------+--------+-----------+ | Role | User | Group | Project | Domain | System | Inherited | +----------------------------------+----------------------------------+-------+----------------------------------+--------+--------+-----------+ | 5eee0910aeb844a1b82f48100da7adc9 | 2f5041ed122d4a50890c34ea02881b47 | | e3a549077f354998aa1a75677cfde62e | | | False | | 5eee0910aeb844a1b82f48100da7adc9 | 67bd1f9c48174e3e96bb41e0f76687ca | | e3a549077f354998aa1a75677cfde62e | | | False |
(2)创建neutron服务及服务端点
# 创建network类型neutron服务 [root@controller ~]# openstack service create --name neutron network +---------+----------------------------------+ | Field | Value | +---------+----------------------------------+ | enabled | True | | id | 459c365a11c74e5894b718b5406022a8 | | name | neutron | | type | network | +---------+----------------------------------+ # 创建3个服务端点 [root@controller ~]# openstack endpoint create --region RegionOne neutron public http://controller:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 1d59d497c89c4fa9b8789d685fab9fe5 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 459c365a11c74e5894b718b5406022a8 | | service_name | neutron | | service_type | network | | url | http://controller:9696 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne neutron internal http://controller:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 44de22606819441aa845b370a9304bf5 | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 459c365a11c74e5894b718b5406022a8 | | service_name | neutron | | service_type | network | | url | http://controller:9696 | +--------------+----------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne neutron admin http://controller:9696 +--------------+----------------------------------+ | Field | Value | +--------------+----------------------------------+ | enabled | True | | id | 75e7eaf8bc664a2c901b7ad58141bedc | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 459c365a11c74e5894b718b5406022a8 | | service_name | neutron | | service_type | network | | url | http://controller:9696 | +--------------+----------------------------------+
(3)启动控制节点上的neutron服务
由于修改了nova的配置文件,启动neutron服务前,需要重启nova服务
# 重启nova服务 [root@controller ~]# systemctl restart openstack-nova-api # 服务开机启动 [root@controller ~]# systemctl enable neutron-server neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-server.service to /usr/lib/systemd/system/neutron-server.service. Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-linuxbridge-agent.service to /usr/lib/systemd/system/neutron-linuxbridge-agent.service. Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-dhcp-agent.service to /usr/lib/systemd/system/neutron-dhcp-agent.service. Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-metadata-agent.service to /usr/lib/systemd/system/neutron-metadata-agent.service. [root@controller neutron]# systemctl start neutron-server neutron-linuxbridge-agent neutron-dhcp-agent neutron-metadata-agent
4、检测控制节点上的neutron服务
# 方法一:查看端口占用情况 [root@controller neutron]# netstat -tnlup|grep 9696 tcp 0 0 0.0.0.0:9696 0.0.0.0:* LISTEN 4652/server.log # 方法二:检验服务端点 [root@controller neutron]# curl http://controller:9696 {"versions": [{"status": "CURRENT", "id": "v2.0", "links": [{"href": "http://controller:9696/v2.0/", "rel": "self"}]}]} # 方法三:查看服务运行状态 # Loaded:值为enabled,表示服务以及设置了开机启动 # Active:值为active(running),表示服务当前处于运行状态 [root@controller neutron]# systemctl status neutron-server ● neutron-server.service - OpenStack Neutron Server Loaded: loaded (/usr/lib/systemd/system/neutron-server.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2022-11-11 16:31:20 CST; 5min ago Main PID: 4652 (/usr/bin/python)
5、安装和配置计算节点的neutron服务
均在计算节点上完成
(1)安装neutron软件包
# 计算节点安装软件包,包含网桥和网络提供者的相关软件 [root@compute ~]# yum install -y openstack-neutron-linuxbridge # 查看neutron用户和用户组 [root@compute ~]# cat /etc/passwd | grep neutron neutron:x:989:986:OpenStack Neutron Daemons:/var/lib/neutron:/sbin/nologin [root@compute ~]# cat /etc/group | grep neutron neutron:x:986:
(2)修改neutron配置文件
要对neutron组件,网桥代理,Nova组件进行配置
1.neutron配置文件
# 备份配置文件 [root@compute ~]# cp /etc/neutron/neutron.conf /etc/neutron/neutron.conf.bak # 去除空行和注释 [root@compute ~]# grep -Ev '^$|#' /etc/neutron/neutron.conf.bak > /etc/neutron/neutron.conf [root@compute ~]# cat /etc/neutron/neutron.conf [DEFAULT] [cors] [database] [keystone_authtoken] # 修改Neutron配置文件 [root@compute ~]# vi /etc/neutron/neutron.conf [DEFAULT] transport_url = rabbit://rabbitmq:000000@controller:5672 auth_strategy = keystone [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = project username = neutron password = 000000 [oslo_concurrency] lock_path = /var/lib/neutron/tmp
2.网桥代理配置文件
# 网桥代理的配置文件备份和去空行和注释 [root@compute ~]# cp /etc/neutron/plugins/ml2/linuxbridge_agent.ini /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak [root@compute ~]# grep -Ev '^$|#' /etc/neutron/plugins/ml2/linuxbridge_agent.ini.bak > /etc/neutron/plugins/ml2/linuxbridge_agent.ini # 修改网桥代理的配置文件 [root@compute ~]# vi /etc/neutron/plugins/ml2/linuxbridge_agent.ini [DEFAULT] [linux_bridge] physical_interface_mappings = provider:ens34 [vxlan] enable_vxlan = false [securitygroup] enable_security_group = true firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
3.nova配置文件
# 在Nova配置文件中,需要在[DEFAULT]部分加入两行内容。在[neutron]部分加入内容 [root@compute ~]# vi /etc/nova/nova.conf [DEFAULT] enable_apis = osapi_compute,metadata transport_url = rabbit://rabbitmq:000000@controller:5672 my_ip = 192.168.10.20 use_neutron = true firewall_driver = nova.virt.firewall.NoopFirewallDriver vif_plugging_is_fatal = false vif_plugging_timeout = 0 [neutron] auth_url = http://controller:5000 auth_type = password project_domain_name = default user_domain_name = default region_name = RegionOne project_name = project username = neutron password = 000000
(3)启动计算节点neutron服务
[root@compute ~]# systemctl restart openstack-nova-compute [root@compute ~]# systemctl enable neutron-linuxbridge-agent Created symlink from /etc/systemd/system/multi-user.target.wants/neutron-linuxbridge-agent.service to /usr/lib/systemd/system/neutron-linuxbridge-agent.service. [root@compute ~]# systemctl start neutron-linuxbridge-agent
6、检测neutron服务
2种方法检测neutron组件的运行状态,均在控制节点执行
# 方法一:查看网络代理服务列表 # 查询出四个数据,均为UP状态 [root@controller ~]# openstack network agent list +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ | ID | Agent Type | Host | Availability Zone | Alive | State | Binary | +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ | 0e2c0f8f-8fa7-4b64-8df2-6f1aedaa7c2b | Linux bridge agent | compute | None | :-) | UP | neutron-linuxbridge-agent | | c6688165-593d-4c5e-b25c-5ff2b6c75866 | Linux bridge agent | controller | None | :-) | UP | neutron-linuxbridge-agent | | dc335348-5639-40d1-b121-3abfc9aefc8e | Metadata agent | controller | None | :-) | UP | neutron-metadata-agent | | ddc49378-aea8-4f2e-b1b4-568fa4c85038 | DHCP agent | controller | nova | :-) | UP | neutron-dhcp-agent | +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ # 方法二:用Neutron状态检测工具检测 [root@controller ~]# neutron-status upgrade check +---------------------------------------------------------------------+ | Upgrade Check Results | +---------------------------------------------------------------------+ | Check: Gateway external network | | Result: Success | | Details: L3 agents can use multiple networks as external gateways. | +---------------------------------------------------------------------+ | Check: External network bridge | | Result: Success | | Details: L3 agents are using integration bridge to connect external | | gateways | +---------------------------------------------------------------------+ | Check: Worker counts configured | | Result: Warning | | Details: The default number of workers has changed.

7、安装完成情况检测
# 1.控制节点外网卡设置了混杂模式(PROMISC) [root@controller ~]# ip a 3: ens34: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 # 2.计算节点外网卡设置了混杂模式(PROMISC) [root@compute ~]# ip a 3: ens34: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000 # 3.控制节点创建neutron用户和用户组 [root@controller ~]# cat /etc/passwd | grep neutron neutron:x:990:987:OpenStack Neutron Daemons:/var/lib/neutron:/sbin/nologin [root@controller ~]# cat /etc/group | grep neutron neutron:x:987: # 4.计算节点创建neutron用户和用户组 [root@compute ~]# cat /etc/passwd | grep neutron neutron:x:989:986:OpenStack Neutron Daemons:/var/lib/neutron:/sbin/nologin [root@compute ~]# cat /etc/group | grep neutron neutron:x:986: # 5.控制节点是否建立neutron数据库 [root@controller ~]# mysql -uroot -p000000 MariaDB [(none)]> show databases; +--------------------+ | Database | +--------------------+ | glance | | information_schema | | keystone | | mysql | | neutron | # 6.检查neutron用户对数据库的权限 MariaDB [(none)]> show grants for neutron; +--------------------------------------------------------------------------------------------------------+ | Grants for neutron@% | +--------------------------------------------------------------------------------------------------------+ | GRANT USAGE ON *.* TO 'neutron'@'%' IDENTIFIED BY PASSWORD '*032197AE5731D4664921A6CCAC7CFCE6A0698693' | | GRANT ALL PRIVILEGES ON `neutron`.* TO 'neutron'@'%' | +--------------------------------------------------------------------------------------------------------+ # 7.检查neutron数据库中的数据表是否同步 MariaDB [(none)]> use neutron; Database changed MariaDB [neutron]> show tables; +-----------------------------------------+ | Tables_in_neutron | +-----------------------------------------+ | address_scopes | | agents | | alembic_version | | allowedaddresspairs | | arista_provisioned_nets | | arista_provisioned_tenants | # 8.检查openstack用户列表 [root@controller ~]# openstack user list | grep neutron | 67bd1f9c48174e3e96bb41e0f76687ca | neutron | # 9.查看neutron用户是否有ADMIN权限 [root@controller ~]# openstack role list | grep admin | 5eee0910aeb844a1b82f48100da7adc9 | admin | [root@controller ~]# openstack role assignment list | grep 67bd1f9c48174e3e96bb41e0f76687ca | 5eee0910aeb844a1b82f48100da7adc9 | 67bd1f9c48174e3e96bb41e0f76687ca | | e3a549077f354998aa1a75677cfde62e | | | False | # 10.检查是否创建了服务实体neutron [root@controller ~]# openstack service list +----------------------------------+-----------+-----------+ | ID | Name | Type | +----------------------------------+-----------+-----------+ | 324a07034ea4453692570e3edf73cf2c | glance | image | | 459c365a11c74e5894b718b5406022a8 | neutron | network | # 11.neutron的三个域端点是否创建 [root@controller ~]# openstack endpoint list | grep neutron | 1d59d497c89c4fa9b8789d685fab9fe5 | RegionOne | neutron | network | True | public | http://controller:9696 | | 44de22606819441aa845b370a9304bf5 | RegionOne | neutron | network | True | internal | http://controller:9696 | | 75e7eaf8bc664a2c901b7ad58141bedc | RegionOne | neutron | network | True | admin | http://controller:9696 # 12.查看网络代理列表,检查服务是否正常运行 [root@controller ~]# openstack network agent list +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ | ID | Agent Type | Host | Availability Zone | Alive | State | Binary | +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+ | 0e2c0f8f-8fa7-4b64-8df2-6f1aedaa7c2b | Linux bridge agent | compute | None | :-) | UP | neutron-linuxbridge-agent | | c6688165-593d-4c5e-b25c-5ff2b6c75866 | Linux bridge agent | controller | None | :-) | UP | neutron-linuxbridge-agent | | dc335348-5639-40d1-b121-3abfc9aefc8e | Metadata agent | controller | None | :-) | UP | neutron-metadata-agent | | ddc49378-aea8-4f2e-b1b4-568fa4c85038 | DHCP agent | controller | nova | :-) | UP | neutron-dhcp-agent | +--------------------------------------+--------------------+------------+-------------------+-------+-------+---------------------------+
六:仪表盘服务(dashboard)部署
提供了图形化界面来管理openstack平台,就是一个web前端控制台
1、安装dashboard软件包
在计算节点安装dashboard软件包
[root@compute ~]# yum install -y openstack-dashboard
2、修改horizon配置文件
# 修改Horizon配置文件 [root@compute ~]# vi /etc/openstack-dashboard/local_settings # 控制节点位置 OPENSTACK_HOST = "controller" OPENSTACK_KEYSTONE_URL = "http://%s:5000/v3" % OPENSTACK_HOST # 启用对多域的支持 OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT = True # 配置API版本 OPENSTACK_API_VERSIONS = { "identity": 3, "image": 2, "volume": 3 } # 配置通过仪表盘创建的用户默认域为Default OPENSTACK_KEYSTONE_DEFAULT_DOMAIN = "Default" # 配置通过仪表盘创建的用户默认角色为user OPENSTACK_KEYSTONE_DEFAULT_ROLE = "user" # 修改配置二层网络 OPENSTACK_NEUTRON_NETWORK = { 'enable_auto_allocated_network': False, 'enable_distributed_router': False, 'enable_fip_topology_check': False, 'enable_ha_router': False, 'enable_ipv6': False, 'enable_quotas': False, 'enable_rbac_policy': False, 'enable_router': False, 'default_dns_nameservers': [], 'supported_provider_types': ['*'], 'segmentation_id_range': {}, 'extra_provider_types': {}, 'supported_vnic_types': ['*'], 'physical_networks': [], } # 配置时区 TIME_ZONE = "Asia/Shanghai" # 允许从任意主机访问 ALLOWED_HOSTS = ['*'] # 配置使用缓存服务 CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': 'controller:11211', }, } SESSION_ENGINE = 'django.contrib.sessions.backends.cache'
(3)重建apache下dashboard配置文件
dashboard是一个web应用,必须运行在apache这样的服务器因此要设置让apache知道如何运行该服务
# 进入Dashboard网站目录 [root@compute ~]# cd /usr/share/openstack-dashboard/ [root@compute openstack-dashboard]# ls manage.py manage.pyc manage.pyo openstack_dashboard static # 编译生成Dashboard的WEB服务文件 [root@compute openstack-dashboard]# python manage.py make_web_conf --apache > /etc/httpd/conf.d/openstack-dashboard.conf [root@compute openstack-dashboard]# cat /etc/httpd/conf.d/openstack-dashboard.conf <VirtualHost *:80> ServerAdmin [email protected] ServerName openstack_dashboard DocumentRoot /usr/share/openstack-dashboard/ LogLevel warn ErrorLog /var/log/httpd/openstack_dashboard-error.log CustomLog /var/log/httpd/openstack_dashboard-access.log combined WSGIScriptReloading On WSGIDaemonProcess openstack_dashboard_website processes=3 WSGIProcessGroup openstack_dashboard_website WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On WSGIScriptAlias / /usr/share/openstack-dashboard/openstack_dashboard/wsgi.py <Location "/"> Require all granted </Location> Alias /static /usr/share/openstack-dashboard/static <Location "/static"> SetHandler None </Location> </Virtualhost>
这样就是实现了apache的web服务器配置目录下生成一个配置文件
4、建立策略文件软连接
在/etc/openstack-dashboard目录下保存了一些dashboard与其他组件交互式的默认策略
# 查看交互默认策略 [root@compute ~]# cd /etc/openstack-dashboard/ [root@compute openstack-dashboard]# ls cinder_policy.json keystone_policy.json neutron_policy.json nova_policy.json glance_policy.json local_settings nova_policy.d # 将这些策略链接到Dashboard项目中,让策略生效 [root@compute openstack-dashboard]# ln -s /etc/openstack-dashboard /usr/share/openstack-dashboard/openstack_dashboard/conf [root@compute openstack-dashboard]# ll /usr/share/openstack-dashboard/openstack_dashboard/ total 240 drwxr-xr-x 3 root root 4096 Nov 18 15:00 api lrwxrwxrwx 1 root root 24 Nov 18 15:33 conf -> /etc/openstack-dashboard
5、启动服务并验证
# Apaceh服务开机启动和重启 [root@compute ~]# systemctl enable httpd Created symlink from /etc/systemd/system/multi-user.target.wants/httpd.service to /usr/lib/systemd/system/httpd.service. [root@compute ~]# systemctl restart httpd
访问计算节点的ip地址
用户名admin,密码000000
七: 块存储服务(cinder部署)
控制节点和计算节点部署配置cinder服务
1、控制节点安装和配置cinder
(1)安装cinder软件包
在openstack-cinder软件包中包括cinder-api和cindder-scheduler模块
# 安装cinder软件包 [root@controller ~]# yum install -y openstack-cinder # 查看cinder用户和用户组 [root@controller ~]# cat /etc/passwd | grep cinder cinder:x:165:165:OpenStack Cinder Daemons:/var/lib/cinder:/sbin/nologin [root@controller ~]# cat /etc/group | grep cinder nobody:x:99:nova,cinder cinder:x:165:cinder
(2)创建cinder数据库并授权
# 登录数据库 [root@controller ~]# mysql -uroot -p000000 # 创建cinder数据库 MariaDB [(none)]> CREATE DATABASE cinder; Query OK, 1 row affected (0.004 sec) # 给cinder用户授权本地和远程访问 MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.007 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY '000000'; Query OK, 0 rows affected (0.000 sec)
(3)修改cinder配置文件
# 备份配置文件 [root@controller ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak # 去除配置文件空行和注释 [root@controller ~]# grep -Ev '^$|#' /etc/cinder/cinder.conf.bak > /etc/cinder/cinder.conf # 编辑配置文件 [root@controller ~]# vi /etc/cinder/cinder.conf [DEFAULT] auth_stategy = keystone transport_url = rabbit://rabbitmq:000000@controller:5672 [database] connection = mysql+pymysql://cinder:000000@controller/cinder [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password username = cinder password = 000000 project_name = project user_domain_name = Default project_domain_name = Default [oslo_concurrency] lock_path = /var/lib/cinder/tmp
(4)修改Nova配置文件
cinder与nova交互,需要修改nova配置文件
[root@controller ~]# vi /etc/nova/nova.conf [cinder] os_region_name = RegionOne
(5)初始化cinder数据库
# 执行初始化操作,同步数据库 [root@controller ~]# su cinder -s /bin/sh -c "cinder-manage db sync" Deprecated: Option "logdir" from group "DEFAULT" is deprecated. Use option "log-dir" from group "DEFAULT". # 验证查看cinder库里的表 MariaDB [cinder]> show tables; +----------------------------+ | Tables_in_cinder | +----------------------------+ | attachment_specs | | backup_metadata | | backups |
(6)创建cinder用户并分配角色
# 模拟登陆 [root@controller ~]# source admin-login # 平台创建cinder用户 [root@controller ~]# openstack user create --domain default --password 000000 cinder +---------------------+----------------------------------+ | Field | Value | +---------------------+----------------------------------+ | domain_id | default | | enabled | True | | id | b9a2bdfcbf3b445ab0db44c9e35af678 | | name | cinder | | options | {} | | password_expires_at | None | +---------------------+----------------------------------+ # 给用户cinder分配admin角色 [root@controller ~]# openstack role add --project project --user cinder admin
(7)创建cinder服务及端点
# 创建服务 [root@controller ~]# openstack service create --name cinderv3 volumev3 +---------+----------------------------------+ | Field | Value | +---------+----------------------------------+ | enabled | True | | id | 90dc0dcf9879493d98144b481ea0df2b | | name | cinderv3 | | type | volumev3 | +---------+----------------------------------+ # 创建服务端点 [root@controller ~]# openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | 6bb167be751241d1922a81b6b4c18898 | | interface | public | | region | RegionOne | | region_id | RegionOne | | service_id | 90dc0dcf9879493d98144b481ea0df2b | | service_name | cinderv3 | | service_type | volumev3 | | url | http://controller:8776/v3/%(project_id)s | +--------------+------------------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | e8ad2286c57443a5970e9d17ca33076a | | interface | internal | | region | RegionOne | | region_id | RegionOne | | service_id | 90dc0dcf9879493d98144b481ea0df2b | | service_name | cinderv3 | | service_type | volumev3 | | url | http://controller:8776/v3/%(project_id)s | +--------------+------------------------------------------+ [root@controller ~]# openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s +--------------+------------------------------------------+ | Field | Value | +--------------+------------------------------------------+ | enabled | True | | id | dd6d3b221e244cd5a5bb6a2b33159c1d | | interface | admin | | region | RegionOne | | region_id | RegionOne | | service_id | 90dc0dcf9879493d98144b481ea0df2b | | service_name | cinderv3 | | service_type | volumev3 | | url | http://controller:8776/v3/%(project_id)s | +--------------+------------------------------------------+
(8)启动cinder服务
# 重启nova服务(配置文件改过了) [root@controller ~]# systemctl restart openstack-nova-api # 开机启动 [root@controller ~]# systemctl enable openstack-cinder-api openstack-cinder-scheduler Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-api.service to /usr/lib/systemd/system/openstack-cinder-api.service. Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-scheduler.service to /usr/lib/systemd/system/openstack-cinder-scheduler.service. # 立即启动 [root@controller ~]# systemctl start openstack-cinder-api openstack-cinder-scheduler
(9)检测控制节点cinder服务
# 方法一:查看8776端口占用情况 [root@controller ~]# netstat -nutpl | grep 8776 tcp 0 0 0.0.0.0:8776 0.0.0.0:* LISTEN 15517/python2 # 方法二:查看存储服务列表,是否处于UP状态 [root@controller ~]# openstack volume service list +------------------+------------+------+---------+-------+----------------------------+ | Binary | Host | Zone | Status | State | Updated At | +------------------+------------+------+---------+-------+----------------------------+ | cinder-scheduler | controller | nova | enabled | up | 2022-11-18T11:08:47.000000 | +------------------+------------+------+---------+-------+----------------------------+
2、搭建存储节点
(1)为计算节点添加硬盘
(2)创建卷组
cinder使用lvm来实现块设备(卷)的管理
# 1.查看系统硬盘挂载情况 [root@compute ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 40G 0 disk ├─sda1 8:1 0 1G 0 part /boot └─sda2 8:2 0 39G 0 part ├─centos-root 253:0 0 35G 0 lvm / └─centos-swap 253:1 0 4G 0 lvm [SWAP] sdb 8:16 0 40G 0 disk 《—————sdb设备还没有分区和挂载 sr0 11:0 1 1024M 0 rom # 2.创建LVM物理卷组 # 2.1 硬盘初始化为物理卷 [root@compute ~]# pvcreate /dev/sdb Physical volume "/dev/sdb" successfully created. # 2.2 物理卷归并为卷组 # 格式:vgcreate 卷组名 物理卷... [root@compute ~]# vgcreate cinder-volumes /dev/sdb Volume group "cinder-volumes" successfully created # 2.3 修改LVM配置 # 在配置文件中的devices部分,添加过滤器,只接受/dev/sdb # a表示接受,r表示拒绝 [root@compute ~]# vi /etc/lvm/lvm.conf devices { filter = ["a/sdb/","r/.*/"] # 3.启动LVM元数据服务 [root@compute ~]# systemctl enable lvm2-lvmetad [root@compute ~]# systemctl start lvm2-lvmetad
3、安装和配置存储节点
均在计算节点操作
(1)安装cinder相关的软件包
openstack-cinder是cinder的软件包
targetcli是一个命令行工具,用于管理Linux的存储资源
python-keystone是与keystone的连接插件
[root@compute ~]# yum install -y openstack-cinder targetcli python-keystone
(2)配置文件修改
# 备份配置文件 [root@compute ~]# cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak # 去除空行和注释 [root@compute ~]# grep -Ev '^$|#' /etc/cinder/cinder.conf.bak > /etc/cinder/cinder.conf # 修改配置文件 # 配置文件中“volume_group”的值应和“创建LVM物理卷组”部分创建的卷组名一致:cinder-volumes [root@compute ~]# vi /etc/cinder/cinder.conf [DEFAULT] auth_stategy = keystone transport_url = rabbit://rabbitmq:000000@controller:5672 enabled_backends = lvm glance_api_servers = http://controller:9292 [lvm] volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver volume_group = cinder-volumes target_protocol = iscsi target_helper = lioadm [database] connection = mysql+pymysql://cinder:000000@controller/cinder [keystone_authtoken] auth_url = http://controller:5000 memcached_servers = controller:11211 auth_type = password username = cinder password = 000000 project_name = project user_domain_name = Default project_domain_name = Default [oslo_concurrency] lock_path = /var/lib/cinder/tmp
(3)存储节点启动cinder服务
[root@compute ~]# systemctl enable openstack-cinder-volume target Created symlink from /etc/systemd/system/multi-user.target.wants/openstack-cinder-volume.service to /usr/lib/systemd/system/openstack-cinder-volume.service. Created symlink from /etc/systemd/system/multi-user.target.wants/target.service to /usr/lib/systemd/system/target.service. [root@compute ~]# systemctl start openstack-cinder-volume target
4、检查cinder服务
# 方法一:查看存储服务列表 # 查看Cinder服务中各个模块的服务状态 [root@controller ~]# openstack volume service list +------------------+-------------+------+---------+-------+----------------------------+ | Binary | Host | Zone | Status | State | Updated At | +------------------+-------------+------+---------+-------+----------------------------+ | cinder-scheduler | controller | nova | enabled | up | 2022-11-18T12:15:46.000000 | | cinder-volume | compute@lvm | nova | enabled | up | 2022-11-18T12:15:43.000000 | +------------------+-------------+------+---------+-------+----------------------------+ # 方法二:查看Dashboard检查卷状态 # 1.左侧导航栏出现卷的选项 # 2.在项目概况中出现卷、卷快照、卷存储三个饼图
5、用cinder创建卷
(1)命令模式创建卷
要在控制节点上面执行命令
[root@controller ~]# openstack volume create --size 8 volume1 +---------------------+--------------------------------------+ | Field | Value | +---------------------+--------------------------------------+ | attachments | [] | | availability_zone | nova | | bootable | false | | consistencygroup_id | None | | created_at | 2022-11-25T06:26:14.000000 | | description | None | | encrypted | False | | id | 690449e4-f950-4949-a0d4-7184226a2447 | | migration_status | None | | multiattach | False | | name | volume1 | | properties | | | replication_status | None | | size | 8 | | snapshot_id | None | | source_volid | None | | status | creating | | type | __DEFAULT__ | | updated_at | None | | user_id | f4f16d960e0643d7b5a35db152c87dae | +---------------------+--------------------------------------+ [root@controller ~]# openstack volume list +--------------------------------------+---------+-----------+------+-------------+ | ID | Name | Status | Size | Attached to | +--------------------------------------+---------+-----------+------+-------------+ | 690449e4-f950-4949-a0d4-7184226a2447 | volume1 | available | 8 | | +--------------------------------------+---------+-----------+------+-------------+
(2)用dashboard创建
