centos安装mysql57

centos默认安装mysql分支MariaDB，这里安装完整版mysql覆盖mariadb，

首先wget方式下载yum安装使用的Repository包

$ wget http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm

 

然后yum安装这个包

yum -y install mysql57-community-release-el7-8.noarch.rpm

 

这时才可以安装mysql

yum -y install mysql-community-server
