 当忘记MySQL的root密码的时候,可以进行如下的步骤重新设置MySQL的root密码:

■■Linux的平台■■

1.首先确认服务器出于安全的状态,也就是没有人能够任意地连接MySQL数据库。
因为在重新设置MySQL的root密码的期间,MySQL数据库完全出于没有密码保护的
状态下,其他的用户也可以任意地登录和修改MySQL的信息。可以采用将MySQL对
外的端口封闭,并且停止Apache以及所有的用户进程的方法实现服务器的准安全
状态。最安全的状态是到服务器的Console上面操作,并且拔掉网线。

2.修改MySQL的登录设置:
# vi /etc/my.cnf
在[mysqld]的段中加上一句:skip-grant-tables
例如:
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
skip-grant-tables
保存并且退出vi。

3.重新启动mysqld
# /etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]

4.登录并修改MySQL的root密码
# /usr/bin/mysql
Welcome to the MySQL monitor. Commands end with ; or /g.
Your MySQL connection id is 3 to server version: 3.23.56

Type 'help;' or '/h' for help. Type '/c' to clear the buffer.

mysql> USE mysql ;
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 ( 'new-password' ) WHERE User = 'root' ;
Query OK, 0 rows affected (0.00 sec)
Rows matched: 2 Changed: 0 Warnings: 0

mysql> flush privileges ;
Query OK, 0 rows affected (0.01 sec)

mysql> quit
Bye

5.将MySQL的登录设置修改回来
# vi /etc/my.cnf
将刚才在[mysqld]的段中加上的skip-grant-tables删除
保存并且退出vi。

6.重新启动mysqld
# /etc/init.d/mysqld restart
Stopping MySQL: [ OK ]
Starting MySQL: [ OK ]

7.恢复服务器的正常工作状态
将步骤一中的操作逆向操作。恢复服务器的工作状态。
