Linux公社整理了网上流传的破解mysql root密码的几种方法:

方法一

使用phpmyadmin,这是最简单的了,修改mysql库的user表,不过别忘了使用PASSWORD函数。

方法二

使用mysqladmin,这是前面声明的一个特例。

mysqladmin -u root -p password mypasswd

输入这个命令后,需要输入root的原密码,,然后root的密码将改为mypasswd。把命令里的root改为你的用户名,你就可以改你自己的密码了。

当然如果你的mysqladmin连接不上mysql server,或者你没有办法执行mysqladmin,那么这种方法就是无效的,而且mysqladmin无法把密码清空。

下面的方法都在mysql提示符下使用,且必须有mysql的root权限:

方法三mysql> Insert INTO mysql.user (Host,User,Password)

VALUES(’%’,’jeffrey’,PASSWORD(’biscuit’));

mysql> FLUSH PRIVILEGES

确切地说这是在增加一个用户,用户名为jeffrey,密码为biscuit。 在《mysql中文参考手册》里有这个例子,所以我也就写出来了。

注意要使用PASSWORD函数,然后还要使用FLUSH PRIVILEGES。

方法四 和方法三一样,只是使用了REPLACE语句 mysql> REPLACE INTO mysql.user (Host,User,Password)

VALUES(’%’,’jeffrey’,PASSWORD(’biscuit’)); mysql> FLUSH PRIVILEGES

方法五 使用SET PASSWORD语句, mysql> SET PASSWORD FOR jeffrey@"%" = PASSWORD(’biscuit’);

拟也必须使用PASSWORD()函数,但是不需要使用FLUSH PRIVILEGES。
