MySQL 服务不会在 XAMPP 上启动

Question

我安装了 MySQL Server 5.6，但不久之后我不得不安装 XAMPP。

当我尝试启动 MySQL 时，它只是挂在...

日志中的错误如下...

我尝试在服务中停止 MySQL56 服务，但还是不行

我也尝试将 my.ini 中的端口更改为 3307，但仍然没有成功

在这些更改之后，我显然已经重新启动了所有内容，但它只是一直在尝试启动

卸载两者并重新安装包含 MySQL 的 XAMPP。很多时候，这些安装将以管理员身份运行，然后如果它将您视为不同的用户，您将无权修改它们。

您也可以尝试右键单击图标启动 XAMPP，然后在卸载/重新安装之前选择“以管理员身份运行”，看看是否可以解决。
