前言
MariaDB数据库管理系统是MySQL的一个分支，主要由开源社区在维护，采用GPL授权许可。开发这个分支的原因之一是：甲骨文公司收购了MySQL后，有将MySQL闭源的潜在风险，因此社区采用分支的方式来避开这个风险。[3]
MariaDB的目的是完全兼容MySQL，包括API和命令行，使之能轻松成为MySQL的代替品。在存储引擎方面，10.0.9版起使用XtraDB（名称代号为Aria）来代替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)试着去启动mysql服务，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
下面讲正确的步骤
# yum install mariadb-server -ysystemctl stop mariadb.service # 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 Server Copyright (c) 2000, 2015, Oracle, MariaDB Corporation Ab and others.

搞定!
