SQL数据库¶
Most OpenStack services use an SQL database to store information. The database typically runs on the controller node. The procedures in this guide use MariaDB or MySQL depending on the distribution. OpenStack services also support other SQL databases including PostgreSQL.
安全并配置组件¶
安装软件包：
# apt install mysql-server python-pymysql
创建并编辑
/etc/mysql/conf.d/openstack.cnf，然后完成如下动作：在[mysqld]中，设置“bind-address”值为控制节点的管理网络IP地址以是的其他节点可以通过管理网络访问访问数据库。设置其他关键字来设置一些有用的选项和UTF-8编码：
[mysqld] bind-address = 10.0.0.11 default-storage-engine = innodb innodb_file_per_table = on max_connections = 4096 collation-server = utf8_general_ci character-set-server = utf8
完成安装¶
重启数据库服务：
# service mysql restart
