【问题描述】：
所以，昨晚我关闭了计算机，今天早上当我试图通过 Xampp 控制面板启动 MySQL 时，我收到了臭名昭著的“错误：MySQL 意外关闭”。
我知道之前已经有人问过这个问题，但我已经搜索了解决方案（直到 Google 结果的第三页！），但没有任何效果。 到目前为止，我已经尝试过： - 删除 mysql/data/ibdata1 文件 - 更改端口（即使我检查了端口 3306 上没有任何工作，端口 3*** 上没有任何工作） - 重新启动 - mysql_升级 - 祈祷 - 以管理员身份开始 - 检查是否从服务中禁用了 mysql 服务（不是） - 检查机器上是否安装了另一个 MySQL（连接到端口解决方案） - 除了 Xampp 之外没有安装其他任何东西。

尝试阅读错误日志，似乎问题与大多数人遇到的问题有些不同。我可能需要重新安装 Xampp，但我必须找到一种方法来保存我的数据库，我不知道这将如何发生，因为我什至无法通过 shell 转储它们。
编辑/更新：我在另一台机器上安装了 Xampp 并将数据文件夹复制到其中。它也破坏了另一台机器上的 MySQL。此时，我只想获取数据库。
