忘记MySQL管理员密码的解决办法

一个非常有用的mysql启动参数:--skip-grant-tables, 顾名思义,就是在启动mysql时不启动 grant-tables(授权表)。有什么用呢?当然是忘记管理员密码时用到。

步骤:
 
步骤1. 停止原来进行着的mysql
$ service mysqld stop
注意,如果是Ubuntu系统,这样:
$ sudo service mysql stop

步骤2. 以命令行参数启动mysql
$ /usr/bin/mysqld_safe --skip-grant-tables &

步骤3. 用root登录mysql
一路回车不用输入密码就可以进入mysql shell啦!

$ mysql -u root -p
Enter password: 
Welcome to the MySQL monitor.  Commands end with ; or \g.
