1.安装前需要删除系统已存在的mysql及mariadb

[root@vm172-31-0-6 ~]# rpm -qa|grep mariadb
mariadb-5.5.60-1.el7_5.x86_64
mariadb-libs-5.5.60-1.el7_5.x86_64
使用 yum remove 全部卸载
[root@vm172-31-0-6 ~]# yum remove mysql*
[root@vm172-31-0-6 ~]# yum remove mariadb*

[root@vm172-31-0-6 ~]# find / -name mysql
[root@vm172-31-0-6 ~]# find / -name mariadb
2.安装mariadb
