下载安装包
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
启动服务
systemctl start mariadb.service
此时报错Failed to start mariadb.service: Unit not found.；
yum安装的时候就会校验软件包是否是官方发布的。当然可以给yum添加--nogpgcheck来强制安装。
执行脚本
yum -y install mysql-community-server --nogpgcheck
再次启动服务
systemctl start mysqld.service
