重置MySQL数据库root密码(linux/windows)
linux与windows下重置mysql用户名与密码的方法,需要的朋友可以参考下。
(1)Linux系统在SSH中执行下面的命令即可将MySQL密码重置为diavps
代码如下:
rm -f reset-mysql-root-password.phps
wget http://down.hostwiki.info/mysql/reset-mysql-root-password.phps
php reset-mysql-root-password.phps diavps
注意不要在带有管理面板(如Kloxo或DA)的环境中使用这个方法重置。
脚本中第13行中的以安全模式启动MySQL的命令会因MySQL安装路径不同而不同。
脚本中使用的mysql服务名称为mysqld,部分系统中该服务名可能为mysql,请注意修改。
(2)Windows系统
1、首先停止正在运行的MySQL进程
net stop mysql
如未加载为服务,可直接在进程管理器中进行关闭。
2、以安全模式启动MySQL
在命令行下运行
X:/MySQL/bin/mysqld-nt.exe --skip-grant-tables
3、完成以后就可以不用密码进入MySQL了
X:/MySQL/bin/mysql -u root -p
提示输入密码时直接回车即可。
4、更改密码
>use mysql
>update user set password=password("新密码") where user="root";
>flush privileges;
5、启动MySQL
在任务管理器里关闭所有MySQL的进程,使用下面的命令启动。
net start mysql
