1.终端输入 yum install mysql-server

2:安装完成后 service mysqld status 查看mysql服务 会显示mysqld以停

3:输入  service mysqld start 开启mysql服务

4:输入 mysql   -h   localhost   -u   root  链接上mysql

5:GRANT   ALL   PRIVILEGES   ON   *.*   TO   'root'@'%'   WITH   GRANT   OPTION

赋予任何主机访问数据的权限

如果报错: [Err] 1133 - Can't find any matching row in the user table

可不用理会，直接下一步操作，我也不知道为什么

6:FLUSH   PRIVILEGES 使修改生效

7:EXIT 退出MySQL服务器


完成后为mysql设置密码

1:终端输入mysql -h localhost -u root

2:  mysql>   use mysql;

    mysql>   update user set password=password("root") where user = "root";

    mysql>   flush privileges;

    mysql>   exit;

3:可以登录mysql了, 终端输入mysql -h localhost -uroot -proot
