基于openEuler22.09部署OpenStack Yoga云平台（一）

OpenStack Yoga部署

安装OpenStack

一、基础准备

基于OpenStack经典的三节点环境进行部署，三个节点分别是控制节点（controller）、计算节点（compute）、存储节点（storage），其中存储节点一般只部署存储服务，在资源有限的情况下，可以不单独部署该节点，把存储节点上的服务部署到计算机节点即可。

首先准备三个openEuler22.09环境，节点规划如下：

|----------------|------------|-----------------|
| 虚拟机版本 | 主机名 | IP地址 |
| openEuler22.09 | Controller | 192.168.110.150 |
| openEuler22.09 | Compute | 192.168.110.151 |
| openEuler22.09 | Storage | 192.168.110.152 |

1.1yum源配置：

打开/etc/yum.repos.d/openEuler.repo文件，检查[EPOL]源是否存在，若不存在，则添加如下内容

[root@controller ~]# vi /etc/yum.repos.d/openEuler.repo

[EPOL]

name=EPOL

baseurl=https://archives.openeuler.openatom.cn/openEuler-22.09/EPOL/main/$basearch/

enabled=1

gpgcheck=1

gpgkey=https://archives.openeuler.openatom.cn/openEuler-22.09/OS/$basearch/RPM-GPG-KEY-openEuler

更新yum源

[root@controller ~]# yum update

若在更新yum源时出现如下图所示问题，则需要更新仓库URL

将 /etc/yum.repos.d/openEuler.repo文件下的URL地址替换成

https://archives.openeuler.openatom.cn/openEuler-22.09/

更换完成之后，保存退出。

1.2修改主机映射

修改每个节点的/etc/hosts文件，新增如下内容：

|----------------------------------------------------------------------------|
| 192.168.110.150 controller 192.168.110.151 compute 192.168.110.152 storage |

1.3设置时间同步

（1）controller节点：

安装服务：

|--------------------------------------------|
| [root@controller ~]# dnf install chrony |

修改/etc/chrony.conf配置文件，新增如下内容：

|------------------------|
| allow 192.168.110.0/24 |

#表示允许哪些IP从本节点同步时钟

重启服务

|---------------------------------------------------|
| [root@controller ~]# systemctl restart chronyd |

（2）其他节点：

安装服务：

|---------------------------------------------------------------------------------|
| [root@compute ~]# dnf install chrony [root@storage ~]# dnf install chrony |

修改/etc/chrony.conf配置文件，新增一行；同时把 pool pool.ntp.org iburst

这一行注释掉，表示不从公网同步时钟。

|-------------------------------|
| server 192.168.110.150 iburst |

表示从这个机器获取时间。

重启服务：

|-----------------------------------------------------------------------------------------------|
| [root@compute ~]# systemctl restart chronyd [root@storage ~]# systemctl restart chronyd |

配置完成后，在其他非controller节点执行chronyc sources，返回结果类似如下内容，表示成功的从controller同步时钟

1.4安装数据库

数据库安装在控制节点，这里推荐使用MariaDB。

（1）安装软件包

|-----------------------------------------------------------------------------------------|
| [root@controller ~]# dnf install mysql-config mariadb mariadb-server python3-PyMySQL |

（2）新增配置文件/etc/my.cnf.d/openstack.cnf，内容如下：

|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [mysqld] bind-address = 192.168.110.150 #本机ip地址 default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8 |

（3）启动服务器

|-------------------------------------------------|
| [root@controller ~]# systemctl start mariadb |

（4）初始化数据库

|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [root@controller ~]# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, and haven't set the root password yet, you should just press enter here. Enter current password for root (enter for none): #这里输入密码，由于我们初始化DB，所以直接回车即可 OK, successfully used password, moving on... Setting the root password or using the unix_socket ensures that nobody can log into the MariaDB root user without the proper authorisation. You already have your root account protected, so you can safely answer 'n'. Switch to unix_socket authentication [Y/n] y Enabled successfully! Reloading privilege tables.. ... Success! You already have your root account protected, so you can safely answer 'n'. Change the root password? [Y/n] y #输入y，修改密码 New password: #密码一定要记住！！！ Re-enter new password: Password updated successfully!

确认镜像上传并验证属性

|----------------------------------------------|
| [root@controller ~]# openstack image list |

2.3Placement

Placement是OpenStack提供的资源调度组件，一般不面向用户，由Nova等组件调用，安装在控制节点。

安装、配置placement服务前，需要先创建相应的数据库、服务凭证和API endpoints。

（1）创建数据库

使用root用户访问数据库服务：

|-----------------------------------------|
| [root@controller ~]# mysql -uroot -p |

创建placement数据库并授权

|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| MariaDB [(none)]> CREATE DATABASE placement; Query OK, 1 row affected (0.001 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'localhost' \ -> IDENTIFIED BY 'PLACEMENT_PASS'; Query OK, 0 rows affected (0.002 sec) MariaDB [(none)]> GRANT ALL PRIVILEGES ON placement.* TO 'placement'@'%' \ -> IDENTIFIED BY 'PLACEMENT_DBPASS'; Query OK, 0 rows affected (0.001 sec) #替换PLACEMENT_DBPASS为placement数据库访问密码 |

（2）配置用户和Endpoints

Source admin凭证，以获取admin命令行权限：

|-------------------------------------------------|
| [root@controller ~]# source ~/.admin-openrc |

创建placement用户并设置用户密码

|---------------------------------------------------------------------------------------------------------------------------------|
| [root@controller ~]# openstack user create --domain default --password-prompt placement User Password: Repeat User Password: |

添加placement用户到service project并指定admin角色

|-------------------------------------------------------------------------------------|
| [root@controller ~]# openstack role add --project service --user placement admin |

创建placement服务实体

|--------------------------------------------------------------------------------------------------------------|
| [root@controller ~]# openstack service create --name placement \ --description "Placement API" placement |

创建placement API服务endpoints

|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [root@controller ~]# openstack endpoint create --region RegionOne \ placement public http://controller:8778 [root@controller ~]# openstack endpoint create --region RegionOne \ placement internal http://controller:8778 [root@controller ~]# openstack endpoint create --region RegionOne \ placement admin http://controller:8778 |

（3）安装及配置组件

安装软件包

|-------------------------------------------------------------|
| [root@controller ~]# dnf install openstack-placement-api |

编辑/etc/placement/placement.conf配置文件，完成如下操作：

在[placement_database]部分，配置数据库入口：

|-----------------------------------------------------------------------------------------------------|
| [placement_database] connection = mysql+pymysql://placement:PLACEMENT_DBPASS@controller/placement |

在[api]和[keystone_authtoken]部分，配置身份认证服务入口

|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [api] auth_strategy = keystone [keystone_authtoken] auth_url = http://controller:5000/v3 memcached_servers = controller:11211 auth_type = password project_domain_name = Default user_domain_name = Default project_name = service username = placement password = PLACEMENT_PASS |

数据库同步，填充placement数据库

|-------------------------------------------------------------------------------|
| [root@controller ~]# su -s /bin/sh -c "placement-manage db sync" placement |

（4）重启服务

|-------------------------------------------------|
| [root@controller ~]# systemctl restart httpd |

（5）验证

Source admin凭证，以获取admin命令行权限

|-------------------------------------------------|
| [root@controller ~]# source ~/.admin-openrc |

执行状态检查

|--------------------------------------------------------|
| [root@controller ~]# placement-status upgrade check |

这里可以看到Policy File JSON to YAML Migration 的结果为Failure。这是因为在placement中，JSON格式的Policy文件从Wallaby版本开始已处于deprecated状态。可以参考提示，使用oslopolicy-convert-json-to-yaml工具将现有的JSON格式Policy文件转化为YAML格式。

|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [root@controller ~]# oslopolicy-convert-json-to-yaml --namespace placement \ > --policy-file /etc/placement/policy.json \ > --output-file /etc/placement/policy.yaml [root@controller ~]# mv /etc/placement/policy.json{,.bak} |

注：当前环境中此问题可忽略，不影响运行

针对placement API运行命令

安装osc-placement插件

|-----------------------------------------------------------|
| [root@controller ~]# dnf install python3-osc-placement |

列出可用的资源类别及特性：

|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| [root@controller ~]# openstack --os-placement-api-version 1.2 resource class list --sort-column name [root@controller ~]# openstack --os-placement-api-version 1.6 trait list --sort-column name |
