方法一:在my.ini的[mysqld]字段加入:
skip-grant-tables
重启mysql服务,这时的mysql不需要密码即可登录数据库然后进入mysql
mysql>use mysql;mysql>更新 user set password=password('新密码') WHERE User='root';
mysql>flush privileges;运行之后最后去掉my.ini中的skip-grant-tables,重启mysqld即可。方法二:不使用修改my.ini重启服务的方法,通过非服务方式加skip-grant-tables运行mysql来修改mysql密码停止mysql服务打开命令行窗口,在bin目录下使用mysqld-nt.exe启动,即在命令行窗口执行: mysqld-nt --skip-grant-tables然后另外打开一个命令行窗口,登录mysql,此时无需输入mysql密码即可进入。按以上方法修改好密码后,关闭命令行运行mysql的那个窗口,此时即关闭了mysql,如果发现mysql仍在运行的话可以结束掉对应进程来关闭。启动mysql服务
