MariaDB和mysql 

 

--mysql-5.7.12-1.el7.x86_64.rpm-bundle.tar

]# ls
mysql-community-client-5.7.12-1.el7.x86_64.rpm
mysql-community-common-5.7.12-1.el7.x86_64.rpm
mysql-community-devel-5.7.12-1.el7.x86_64.rpm
mysql-community-libs-5.7.12-1.el7.x86_64.rpm
mysql-community-server-5.7.12-1.el7.x86_64.rpm

 

一般把以上安装就可用

清理冲突：MariaDB和MySQL 只能安装一个，相互间有冲突，

rpm -qa |grep mariadb
rpm -e --allmatches mariadb-server --nodeps
