MySQL 在 XAMPP 中 apache 工作时意外关闭

Question

当我单击开始按钮时，此消息出现在我的 XAMPP 控制面板中。
此警告显示 MySQL 意外关闭，但 Apache 服务器运行正常。

这是 MySQL 错误日志：

我尝试了在 Whosebug 上找到的大部分内容，但都没有用。
谁能帮我找到解决办法？

Answer 1

我在网上搜索了将近一个小时后发现这很有帮助。您可以通过 solution screenshotted here or browse the XAMPP forum here

Answer 2

这个方法解决了我的问题

步骤 1. 将文件夹 c:\xampp\mysql\data 重命名为 c:\xampp\mysql\data_old（您可以使用任何名称）。

步骤2.新建文件夹c:\xampp\mysql/data.

第 3 步。将 mysql\backup 中的内容复制到新的 mysql\data 文件夹。

第 4 步。将 mysql\data_old 中的所有数据库文件夹复制到 mysql\data（跳过 mysql、performance_schema 和 [=39 中的 phpmyadmin 文件夹=]).

第 5 步。最后从 mysql\data_old 复制 ibdata1 文件并将其替换到 mysql\data 文件夹中。

第 6 步。从 XAMPP 控制面板启动 MySQL。

而且，它完成了。没有丢失数据库，没有更改端口，没有运行管理员身份，没有强制恢复，没有杀死 mysqld 进程，没有从以前的版本恢复，没有更多错误。
