mysql忘记密码,如何重置密码

1.使用mysqladmin修改mysql密码
 C:/>mysqladmin -udbuser -p password newpass
 Enter password: oldpass
 当然用此命令的前提是你把mysql加入了环境变量,如果没有加入环境变量的话那只能在命令行下cd到

mysqladmin所在的目录下与此那个次命令了!
 -----------------------------------------
 2.重置root密码
 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>update 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。
 修改mysql密码方法二:
 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
