mysql的root账号忘记密码了怎么办?经过志文工作室的验证,windows下使用以下步骤即可重置密码,linux下亦可参考相关命令方法解决

Windows下的实际操作如下

  1.关闭正在运行的MySQL。
  2.打开DOS窗口,转到mysqlbin目录。
  3.输入mysqld –skip-grant-tables回车。如果没有出现提示信息,那就对了。
  4.再开一个DOS窗口(因为刚才那个DOS窗口已经不能动了),转到mysqlbin目录。
  5.输入mysql回车,如果成功,将出现MySQL提示符 >
  6. 连接权限数据库:use mysql
  7.改密码:update user set password=password("123456") where user="root"
  8.刷新权限(必须的步骤)>flush privileges
  9.退出 > q
  10.重启mysql服务,或直接重启系统打开MySQL,使用用户名root和刚才设置的新密码123456登陆
