MariaDB Root密码恢复

Posted on Edited on In

本机装了MariaDB，很久不用，把密码给忘记了。

然后刚刚把密码恢复了下，记录一份这里方便以后索引。

  1. 停止MySQL服务。

# systemctl stop mysql 我是Ubuntu 这里服务名是这个

  1. 用无权限管理方式启动

# mysqld_safe --skip-grant-tables &

  1. 登录修改密码

# mysql -uroot

修改密码的SQL

> flush privileges;
> quit
  1. 停止mysql进程

  1. 启动服务 systemctl restart mysql

done.
