另一个方法
Windows:
1. 管理员登陆系统,停止mysql服务或者结束mysqld-nt进程
2. 进入命令行,来到mysql的安装目录.假设安装目录为 d:/mysql/ , CMD进入命令行
3. 运行 d:/mysql/bin/mysqld-nt --skip-grant-tables 启动mysql,关闭权限的检查
4. 运行 d:/mysql/bin/mysqladmin -u root flush-privileges password "newpassword" 重设root密码
5. 重新启动mysql服务
第4步也可以直接修改mysql表,所用到的SQL语句同linux部分,这里就不再重复了.
