第一步：安装从网上下载文件的wget命令

[root@master ~]# yum -y install wget

第二步：下载mysql的repo源

[root@master ~]# wget http://repo.mysql.com/mysql-community-release-el7-5.noarch.rpm 

第三步：安装mysql-community-release-el7-5.noarch.rpm包

[root@master ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

第四步：查看下

[root@master ~]# ls -1 /etc/yum.repos.d/mysql-community*
/etc/yum.repos.d/mysql-community.repo
/etc/yum.repos.d/mysql-community-source.repo

会获得两个mysql的yum repo源：/etc/yum.repos.d/mysql-community.repo，/etc/yum.repos.d/mysql-community-source.repo。

第五步：安装mysql

[root@master ~]# yum install mysql-server

  # 启动mysql服务
      service mysql start
   # 使用初始密码登录mysql服务 并修改密码
      mysql -uroot -p
      alter user ‘root‘@‘localhost‘ identified by ‘root‘;
      flush privileges;
