【Mysql】常用指令之忘记密码_MySQL
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
4、停止 再不通过此参数启动即可。
