yum list installed | grep mysqld/mariadb

rpm -Uvh http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm yum clean all yum repolist
三,安装msyql5.6:
yum -y install mysql-community-server
四,启动服务:
systemctl start mysqld systemctl enable mysqld
五,重置密码:是具体情况而定(可以省略,无密码登陆)
#mysql_secure_installation Set root password? [Y/n] y [设置root用户密码] Remove anonymous users? [Y/n] y [删除匿名用户] Disallow root login remotely? [Y/n] n [禁止root远程登录] Remove test database and access to it? [Y/n] y [删除test数据库] Reload privilege tables now? [Y/n] y [刷新权限]
