我正在尝试让XAMPP在Win7 / 64上运行以测试Wordpress主题。
我最初遇到Apache试图访问的问题 端口80，但我被告知将配置文件更改为端口81，我已经完成了，现在Apache正在运行，localhost：81显示XAMPP控制面板正常。
然而，现在MySQL根本不工作。在我更改配置文件之前，我认为是，但Apache没有运行，所以我仍然无法访问localhost。
在Windows事件查看器中，我收到了关于MySQL的错误报告：
Fatal error: Can't open and lock privilege tables: Can't find file: 'host' (errno: 2)
在XAMPP的控制台中，我现在得到了这个：

是否需要更改配置文件以匹配Apache文件？我看不到任何明显的东西。
非常感谢提前。

通过卸载XAMPP，再次重新安装，然后将Apache使用的端口从80更改为8080来解决问题。
