打开命令行窗口,停止mysql服务:
Net stop mysql
启动mysql,一般到mysql的安装路径,找到 mysqld-nt.exe (或mysqld.exe)
执行:mysqld-nt (或mysqld.exe) --skip-grant-tables 当前窗口将会停止。
另外打开一个命令行窗口,执行mysql 如果提示没有这个命令,先进入MYSQL的安装位置下BIN目录再运行mysql

>use mysql 
>update user set password=password("new_password") where user="root"; 
>flush privileges; 
>exit
Copy after login

用Ctrl+Alt+Del,找到mysqld-nt的进程杀掉它,在重新启动mysql-nt服务,就可以用新密码登录了

在linux下:

如果 MySQL 正在运行,首先杀之: killall -TERM mysqld。
启动 MySQL :bin/safe_mysqld --skip-grant-tables &

>update user set password=password("new_pass") where user="root"; 
>flush privileges;
Copy after login
