上一篇文章基本总结了下myql下通过指令怎么创建用户,详见:【Mysql】常用指令之——用户操作(创建,授权,修改,删除)

今天说下特殊情况,忘记密码了怎么办???

重装,删除配置等可以完成此操作。那不重装怎么办呢?

原理:

通过增加启动参数:--skip-grant-tables 跳过grant-tables启动数据库,这样就不需要密码就能进去了。

下面来玩玩:

linux下:

1、关闭mysql进程,应该都会哈比如:service mysql stop 或者 ps -ef | grep mysql kill (mysqlpid)还有rcmysqld stop 等等。

2、增加启动参数:可以编辑/etc/my.ini或者/etc/my.cnf文件,增加启动参数--skip-grant-tables 也可以用命令: /usr/bin/mysqld_safe --skip-grant-tables & 来启动mysql

3、无密码进入系统修改密码: mysql -u root -p 即可。

window下也是一样的只是操作不一样。

1、我的电脑右键》管理》服务》找到mysql 并停止 或者 win+R 运行cmd 然后运行 net stop mysql

2、利用--skip-grant-tables参数来启动数据库。

C:\Users\WJ>net stop mysql
MySQL 服务正在停止..
MySQL 服务已成功停止。

C:\Users\WJ>mysqld --skip-grant-tables
Copy after login
3、用root登陆吧,任意枉为 去吧。 

4、停止 再不通过此参数启动即可。
