**Windows:**

1.以系统管理员登陆；

2.停止MySQL服务；

3.进入CMD，进入MySQL的安装目录，假设是D:/MySQL/MySQL Server 5.0/；

4.跳过权限检查启动MySQL，

D:/MySQL/MySQL Server 5.0/bin/mysqld-nt –skip-grant-tables

5.重新打开一个CMD，进入D:/MySQL/MySQL Server 5.0/bin/，

重设root密码

D:/MySQL/MySQL Server 5.0/bin/mysqladmin -uroot flush-privileges password “newpassword”

D:/MySQL/MySQL Server 5.0/bin/mysqladmin -u root -p shutdown

将newpassword替换为你的新密码，第二个命令会让你重复输入一次新 密码。

6. 在cmd里net start mysql

**Unix&Linux：**

1.用root或者运行mysqld的用户登录系统；

2.利用kill命令结束掉mysqld的进程；

3.使用–skip-grant-tables参数启动MySQL Server

\#mysqld\_safe –skip-grant-tables &

4.然后用空密码方式使用root用户登录 MySQL；mysql -u root

5.为root@localhost设置新密码

mysql> update mysql.user set password=PASSWORD（'新密码'） where User='root'mysql> flush privileges；mysql> quit

6. 重新启动MySQL
