1 检查并删除现有mariadb安装包

rpm -qa|grep mariadb
rpm -e --nodeps mariadb-libs-xxx.xxx

2 安装mysql包（依赖按顺序安装）

rpm -ivh mysql-community-common-5.7.20-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.20-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-compat-5.7.20-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.20-1.el6.x86_64.rpm
rpm -ivh mysql-community-server-5.7.20-1.el6.x86_64.rpm
若安装server包报错，执行强制安装
rpm -ivh mysql-community-server-5.7.20-1.el6.x86_64.rpm --force --nodeps

检测已安装的包

rpm -qa | grep mysql

启动mysql服务

service mysqld start

查看默认密码

cat /var/log/mysqld.log | grep password
