vi /etc/my.cnf
在[mysqld]的段中加上一句：skip-grant-tables
保存並且退出vi。
2、重新啓動mysqld
[root@lan199 ~]# /etc/init.d/mysqld restart

Rows matched: 3Changed: 0Warnings: 0
mysql> flush privileges;

[root@lan199 ~]#
4、將MySQL的登錄設置修改回來
# vi /etc/my.cnf

保存並且退出vi。
5、重新啓動mysqld
# /etc/init.d/mysqld restart

Ok,現在可以使用新密碼登陸mysql數據庫了
mysql -u root –ppassword
