前言
MariaDB數據庫管理系統是MySQL的一個分支，主要由開源社區在維護，采用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，因此社區采用分支的方式來避開這個風險。[3]
MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能輕松成為MySQL的代替品。在存儲引擎方面，10.0.9版起使用XtraDB（名稱代號為Aria）來代替MySQL的InnoDB
# yum install mysql -y # mysql ERROR 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 mysql Failed to issue method call: Unit mysql.service failed to load: No such file or directory. # systemctl start mysql.service Failed to issue method call: Unit mysql.service failed to load: No such file or directory # systemctl enable mysql.service Failed to issue method call: Access denied
下面講正確的步驟
# yum install mariadb-server -y systemctl stop mariadb.service # systemctl start mariadb.service # systemctl enable mariadb.service # mysql Welcome to the MariaDB monitor. Commands end with ; or \g. Your MariaDB connection id is 10 Server version: 5.5.44-MariaDB MariaDB Server Copyright (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!
