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. Your MySQL connection id is 6 Server version: 5.6.28-0ubuntu0.15.04.1 (Ubuntu) Copyright (c) 2000, 2015, Oracle and/or its affiliates. All rights reserved.

Type '\c' to clear the current input statement. mysql>
这时就可以随便操作数据库啦!
