macos - 为什么 apache2 试图执行我的 CSS 和图像文件？

问题描述

我为此苦苦挣扎了两天，在网上搜索线索和答案，发现适用于 Mac 和 CGI​​ 脚本的内容很少。当我收到 500 错误时，可能有很多问题，但我认为它可能就像 apache2 试图执行我的非可执行文件一样简单，即 .css、.js、.png 等。我的配置文件（删除注释行）是这样的：

ServerRoot "/usr"

当我尝试加载我的页面时，Perl 脚本运行，但是嵌入到它提供给浏览器的 HTML 中的链接都出现 http 500 错误（如果我从基本目录的选项中删除了“ExecCGI”，则会出现 403 错误）。

以下是页面加载后日志文件显示的内容：

如图所示，即使是图像文件也被视为需要执行的脚本！自然，他们会遇到语法错误。

更多信息：

Apache 仅在本地托管网站——这不是互联网虚拟主机。这应该是供离线使用和开发目的。

为什么apache2会这样做？配置有什么问题？

解决方案

嗯，这看起来有点狡猾。

<Directory />
    Options FollowSymLinks ExecCGI
    AllowOverride None
</Directory>

首先，这会将您的整个文件系统（/ 下的所有内容）视为 Web 服务器的一部分。其次，您已经ExecCGI为 Apache 服务的每个文件都打开了 - 这会导致您的问题。

您还将实际的 CGI 目录 (/var/www/mywebsite/cgi/) 定义为 CGI 目录两次。
