忘记了mysql的root密码重置方法

Jun 07, 2016 pm 05:51 PM

如果不记得root密码了我们只要修改mysql中user表中的root用户的password改成你的新密码然后刷新权限就好了。

如果忘记了 MySQL 的 root 密码,可以用以下方法重新设置:

  1. KILL掉系统里的MySQL进程;

  2. 用以下命令启动MySQL,以不检查权限的方式启动;

  d_safe -skip-grant-tables &

  3. 然后用空密码方式使用root用户登录 MySQL;

  mysql -u root

  4. 修改root用户的密码;

        mysql> update mysql.user set password=PASSWORD('新密码') where  User='root';

        mysql> flush privileges;

        mysql> quit

  5. 重新启动MySQL,就可以使用新密码登录了。

上面讲述的是利用sql命令来实现,其实我们还可以通过替换mysql use表现修改用户密码方法也差不多,我以前(在同版本号mysql下做过替换 mysql这种做法,如果个数据库里面的数据库不同就千万别操作)。
