一、更改my.cnf配置文件

编辑/etc/my.cnf文件，在[mysqld]下添加skip-grant-tables，保存退出。如图：

重启mysql服务：services mysqld restart

二、更改root密码

重启mysqld服务后，执行mysql命令，进入mysql命令行：

[root@yeebian ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 2

mysql> 

修改root密码

mysql> UPDATE mysql.user SET Password=PASSWORD('mysqladmin') where USER='root';
Query OK, 0 rows affected (0.00 sec)
Rows matched: 3  Changed: 0  Warnings: 0

mysql> flush privileges;

mysql> exit

三、删除/etc/my.cnf中的skip-grant-tables，或者注释掉，重启mysql即可。
