安装配置数据库

1.安装mysql
yum install mariadb mariadb-server MySQL-python


2.创建文件完成下面内容 /etc/my.cnf.d/mariadb_openstack.cnf

a.在 部分，设置bind-address，此为控制节点ip地址

...
bind-address = 10.0.0.11


b.在 部分，完成下面内容

...
default-storage-engine = innodb
innodb_file_per_table
collation-server = utf8_general_ci
init-connect = 'SET NAMES utf8'
character-set-server = utf8


完成安装

启动系统，开启配置数据库服务

systemctl enable mariadb.service
systemctl start mariadb.service


安全数据库服务
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
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? Y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them.This is intended only for testing, and to make the installation
go a bit smoother.You should remove them before moving into a
production environment.

Remove anonymous users? Y
... Success!

Normally, root should only be allowed to connect from 'localhost'.This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? Y
... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access.This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? Y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? Y
... Success!

Cleaning up...

All done!If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

在CentOS7下根本无法启动啊，我试过两天主机了。
提示 Job for rabbitmq-server.service failed. See 'systemctl status rabbitmq-server.service' and 'journalctl -xn' for details.

启用了，最终发现是我改了hosts文件导致的错误。但出错后需要卸载rabbitmq，然后find / 把rabbitmq所有文件删除。然后重新安装才可以。只改hosts然后重启系统没用。
