MySQL的root用户密码往往容易被遗忘,它本身就有一个跳过权限检查启动的机制用来处理权限错误问题。本文分别对Windows环境与Linux环境下介绍MySQL忘记密码/重置密码的方法,希望帮助初学者解决丢失密码的烦恼。 

MySQL for Windows重置密码

一般来说,Windows下的MySQL是安装成服务运行的。本文将以Windows 2003为例。

1、首先在 控制面板 – 管理工具 – 服务 中将MySQL服务停止。

2、以安全模式(跳过权限认证)启动MySQL服务

“开始菜单” – “运行” – 输入“cmd”并回车 – cd至MySQL安装目录下的 bin 目录,然后执行:

 

1 mysqld-nt.exe --skip-grant-tables

3、此时MySQL已经正常运行,通过PhpMyAdmin登录MySQL,用户名root,密码为空或任何其他字符; 

MySQL for Linux重置密码

Linux下重置密码的原理与Windows下类似,,都是采用安全模式跳过权限检查启动MySQL。

1、首先停止MySQL服务,执行如下命令:

 

1 [root@www ~]# /etc/init.d/mysql stop

2、以安全模式启动MySQL:

1 [root@www ~]# /usr/local/mysql/bin/mysqld_safe --skip-grant-tables &

3、此时即可通过phpMyAdmin或者命令行修改密码。用户名为root,密码为空即可。 

附修改密码的命令:

首先以命令行模式登录MySQL:

1 [root@www ~]# mysql -u root -p

然后执行如下三条命令:

>use mysql;
> update user set password=password(“新密码”) where user=”root”;
> flush privileges;
