安装 MySQL

许多 OpenStack 服务维护一个数据库来跟踪重要资源、使用情况和其他信息。尤其是对于多节点配置，请使用数据库（如 MySQL 数据库）存储此信息。

如何安装 MySQL 数据库

1. 启用 RabbitMQ 服务。

   controller# svcadm enable rabbitmq
   controller# svcadm restart rad:local

2. (u53ef选) 如果要将专用 IP 地址用于管理和 API 通信，并且在 /etc/mysql/5.5/my.cnf 中添加该地址：

   bind-address=$CONTROLLER_ADMIN_NODE_IP

3. 启用 MySQL 服务。

   controller# svcadm enable mysql

4. 设置 MySQL 服务器 root 口令。

   controller# mysqladmin -u root password MySQL-root-password

5. 配置 MySQL。

   创建 OpenStack 将使用的表。向控制器节点上的服务授予特权，以便提供对于这些数据库的独占访问。

   controller# mysql -u root -p
   Enter password: MySQL-root-password
   mysql> drop database if exists nova;
   mysql> drop database if exists cinder;
   mysql> drop database if exists glance;
   mysql> drop database if exists keystone;
   mysql> drop database if exists neutron;
   mysql> drop database if exists heat;
   mysql> create database cinder default character set utf8 default collate utf8_general_ci;
   mysql> grant all privileges on cinder.* to 'cinder'@'$CONTROLLER_ADMIN_NODE' identified by 'service-password';
   mysql> create database glance default character set utf8 default collate utf8_general_ci;
   mysql> grant all privileges on glance.* to 'glance'@'$CONTROLLER_ADMIN_NODE' identified by 'service-password';
   mysql> create database keystone default character set utf8 default collate utf8_general_ci;
   mysql> grant all privileges on keystone.* to 'keystone'@'$CONTROLLER_ADMIN_NODE' identified by 'service-password';
   mysql> create database nova default character set utf8 default collate utf8_general_ci;
   mysql> grant all privileges on nova.* to 'nova'@'$CONTROLLER_ADMIN_NODE' identified by 'service-password';
   mysql> create database neutron default character set utf8 default collate utf8_general_ci;
   mysql> grant all privileges on neutron.* to 'neutron'@'$CONTROLLER_ADMIN_NODE' identified by 'service-password';
   mysql> create database heat default character set utf8 default collate utf8_general_ci;
   mysql> grant all privileges on heat.* to 'heat'@'$CONTROLLER_ADMIN_NODE' identified by 'service-password';
   mysql> flush privileges;
   mysql> quit
