1）如果没有忘记密码

可以通过UPDATE直接编辑user表来修改密码：

进入数据库mysql -u root
mysql> use mysql;
mysql> UPDATE user SET Password = PASSWORD('newpass') WHERE user = 'root';
mysql> FLUSH PRIVILEGES;
或者
/etc/init.d/mysql stop
/etc/init.d/mysql start

2）如果您已经忘记密码

# /etc/init.d/mysql stop

1、结束当前正在运行的mysql进程

# /usr/bin/mysqld_safe --skip-grant-tables

2、用mysql安全模式运行并跳过权限验证

# mysql -u root

3、重开一个终端以root身份登录mysql

mysql> use mysql;

4、修改root用户口令
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> update user set Password = PASSWORD('root') where User ='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0

mysql> exit

# /etc/init.d/mysql restart

5、结束mysql安全模式，用正常模式运行mysql

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

6、试试你新修改的口令

mysql> flush privileges；
mysql> quit
