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。 第一步 C:\Documents and Settings\Administrator>cd D:\web\www.php100.com\Mysql\MySQL Se rver5.5\bin C:\Documents and Settings\Administrator>d: D:\web\www.php100.com\Mysql\MySQL Server5.5\bin>mysqld --skip-grant-tables 第二步 Microsoft Windows [版本 5.2.3790] (C) 版权所有 1985-2003 Microsoft Corp.
