openstack Rocky 社区版部署1.4 安装数据库

在控制节点安装mariadb，也可以单独服务器安装数据库，假如多个控制节点就在第一台安装数据库，计算节点不需要安装。

1 安装mariadb相关安装包。

yum install mariadb mariadb-server python2-PyMySQL

2 创建和编辑 /etc/my.cnf.d/openstack.cnf ，bind-address为数据库所在服务器的管理地址，字体选择UTF-8。

[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

3 启用mariadb服务。

systemctl enable mariadb.service

systemctl start mariadb.service

4 初始化mysql数据库。

[root@controller1 packages]# 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/n] 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/n] 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/n] 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/n] 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/n] 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!
