3. 启动 MariaDB 服务器：[root@mcctb ~]# systemctl start mariadb

   示例

   [root@mcctb ~]# systemctl start mariadb
   
   
4. 验证 MariaDB 服务器已启动：[root@mcctb ~]# systemctl status mariadb

   示例

   [root@mcctb ~]# systemctl status mariadb
   mariadb.service - MariaDB database server
   ...
   Nov 08 21:28:59 mcctb systemd[1]: Starting MariaDB database server...
   ...
   Nov 08 21:29:01 scspr0523972001 systemd[1]: Started MariaDB database server.
   
   

   注

   确保为 MariaDB 开启了“启用自动启动”设置。
5. 配置安全性和密码设置：[root@mcctb ~]# mysql_secure_installation

   示例

   [root@mcctb ~]# mysql_secure_installation
   NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
   SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
   Set root password? [Y/n] y
   New password:
   Re-enter new password:
   Password updated successfully!
   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!
   Remove test database and access to it? [Y/n] y
   - Dropping test database...
   ... Success!
   - Removing privileges on test database...
   ... Success!
   Reload privilege tables now? [Y/n]
   ... 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!
