# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

 

  # rpm -ivh mysql-community-release-el7-5.noarch.rpm


  # yum install mysql-community-server


成功安装之后重启mysql服务

 

# service mysqld restart

初次安装mysql是root账户是没有密码的

设置密码的方法

 

# mysql -uroot     


      mysql> set password for ‘root’@‘localhost’ = password('mypasswd');     


      mysql> exit

搞定！
