因此，我有一个运行良好的 Debian 系统，我可以通过转到 73.xx.xx.xx 访问我的 apache 根目录并查看我的主页。还可以通过转到 73.xx.xx.xx/site1 73.xx.xx.xx.xx/site2 访问子文件夹
我进行了 apt 软件升级，现在我仍然可以访问 73.xx.xx.xx 并查看主页，但我无法查看子文件夹。升级是否覆盖了设置，如果是，覆盖了哪一个？
我尝试查看 httpd.conf，但什么也没有。有什么提示吗？

检查浏览器模块，看看是否有任何手动安装的模块没有与 Debian 的其他部分一起升级。我记得我曾经看到过类似的事情发生在 mod_security 的自定义版本上，只有当请求中有子目录时，服务器才会崩溃。如果你自己构建了模块，请参阅此链接并确保您apache2-foo-dev安装了正确的软件包。
