mysql忘记密码进行重设

mysql有时候忘记密码了怎么办?我给出案例和说明!一下就解决了!

  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mysql\bin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mysql\bin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; (>是本来就有的提示符,别忘了最后的分号)

  6.改密码:> update user set password=password("520") where user="root"; (别忘了最后的分号)

  7.刷新权限(必须的步骤)>flush privileges;

  8.退出 > \q

  9.注销系统,再进入,开MySQL,使用用户名root和刚才设置的新密码123456登陆。
