Docker中Mysql容器忘记密码的处理方法

今天非常的倒霉，因为学习了Vue的相关知识，想自己写一个后端服务器来练习一下Vue

然后 忘记了Docker中Mysql的密码。。。

很抽象

下面是我的解决方法

• 一、如果在本地的Navicat Premium上连接过数据库，就可以使用工具导出连接
  
  
• 二、用编辑器打开导出的链接文件 就可以看到 用户名、密码、以及相关链接信息
• 三、我们复制密码（加密后的），进行解密---程序是PHP的 多亏一位Github：https://github.com/tianhe1986/FatSmallTools 上的大佬写了个程序，可以直接破译
• 选择一个在线编译器 https://tool.lu/coderunner/ 把代码粘上去就行了

代码如下

    }
}

use FatSmallTools\NavicatPassword;

//需要指定版本，11或12
$navicatPassword = new NavicatPassword(12);
//$navicatPassword = new NavicatPassword(11);

//解密
//$decode = $navicatPassword->decrypt('15057D7BA390');
$decode = $navicatPassword->decrypt('999239DEBFA1960BCCB12566F1F417A6');
echo $decode."\n";

* 四、替换代码中的倒数第二行字符串，就可以获得连接密码
最后 还是要好好地记住自己的密码啊
