MariaDB資料庫管理系統是MySQL的一個分支，主要由開源社區在維護，採用GPL授權許可。開發這個分支的原因之一是：甲骨文公司收購了MySQL後，有將MySQL閉源的潛在風險，因此社區採用分支的方式來避開這個風險。[3]

MariaDB的目的是完全相容MySQL，包括API和命令列，使之能輕鬆成為MySQL的代替品。在儲存引擎方面，10.0.9版起使用XtraDB（名稱代號為Aria）來代替MySQL的InnoDB

# yum install mysql -y# mysqlERROR 2002 (HY000): Can‘t connect to local MySQL server through socket ‘/var/lib/mysql/mysql.sock‘ (111)

試著去啟動mysql服務，仍然不行

# systemctl start mysqlFailed to issue method call: Unit mysql.service failed to load: No such file or directory.# systemctl start  mysql.serviceFailed to issue method call: Unit mysql.service failed to load: No such file or directory# systemctl enable mysql.serviceFailed to issue method call: Access denied

下面講正確的步驟

# yum install mariadb-server -y# systemctl start mariadb.service# systemctl enable mariadb.service# mysqlWelcome to the MariaDB monitor.  Commands end with ; or \g.Your MariaDB connection id is 10Server version: 5.5.44-MariaDB MariaDB ServerCopyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others.Type ‘help;‘ or ‘\h‘ for help. Type ‘\c‘ to clear the current input statement.MariaDB [(none)]> 

搞定!
