安装
安装之前确保机器上面没有YUM安装的MySQL
# rpm -qa | grep -i mysql
or
# yum remove $(rpm -qa | grep -i mysql )
# yum install MariaDB-server MariaDB-client
启动
# systemctl start mysql.service
# systemctl enable mysql.service
设置root密码

运行 mysql_secure_installation 设置root用户密码、去除test数据库、禁止root帐号远程访问等。推荐
# 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!

选用合适的配置文件
MariaDB会给我们提供示例配置文件，根据机器内存进行选择，稍作修改即可使用。
# ls /usr/share/mysql/my-*
/usr/share/mysql/my-huge.cnf /usr/share/mysql/my-medium.cnf
/usr/share/mysql/my-innodb-heavy-4G.cnf /usr/share/mysql/my-small.cnf
/usr/share/mysql/my-large.cnf
# cp /usr/share/mysql/my-huge.cnf /etc/my.cnf
cp: overwrite ‘/etc/my.cnf’? y
重载配置文件
# systemctl reload mysql.service
