每次我请求一个 .php 文件时，我都会收到 500 错误代码。

我尝试了许多不同的文件权限并搜索了整个互联网（或者至少感觉像这样），但我找不到任何有用的东西。（找到 suexec 错误或类似的东西并不容易。但是我想，这是有权限的东西......而且可能我只是不知道某个/某个点......）

如果有问题，请不要介意语言错误。
是的，您应该能够访问服务器：http ://wiheha.us.to/

我（意外）找到了解决方案：fcgi 脚本（以及包含它的目录）必须至少是公开可执行的（rx--x--x / 511）。

更新的文件结构：

drwxr-xr-x root   root    /var/
drwxr-xr-x root   root      www/
dr-xr-xr-x wiheha wiheha      wiheha/
dr-x--x--x wiheha wiheha        conf.d/
-r-x--x--x wiheha wiheha          php.fcgi
drwxr-xr-x wiheha wiheha        www/

-rw-r--r-- wiheha wiheha          test.html

还要检查以下内容：

特殊的 PHP 注意事项

By default, PHP FastCGI processes exit after handling 500 requests, and they may exit after this module has already connected to the application and sent the next request. When that occurs, an error will be logged and 500 Internal Server Error will be returned to the client. This PHP behavior can be disabled by setting PHP_FCGI_MAX_REQUESTS to 0, but that can be a problem if the PHP application leaks resources. Alternatively, PHP_FCGI_MAX_REQUESTS can be set to a much higher value than the default to reduce the frequency of this problem. FcgidMaxRequestsPerProcess can be set to a value less than or equal to PHP_FCGI_MAX_REQUESTS to resolve the problem.
