nginx 反向代理服务来自错误的虚拟主机

Question

我有一台双四核 Centos 6.3 服务器，配备 32GB 内存。

我已经安装了 nginx 来提供静态文件，并将其作为后端 apache 的反向代理服务器。我使用的面板是 IspConfig 3.0.5.2。

一开始一切似乎都运行良好，但最近我意识到有些不对劲！Nginx 从错误的文档根目录提供服务。我浏览了 Google 和 Nginx 论坛，但找不到解决方案。我对配置文件进行了多次修改/更改/修正，并尝试通过 Nginx 日志进行调试，但毫无效果！

以下是我的配置文件和日志摘录。请帮我整理一下。

以下是日志文件的摘录，采用我的自定义格式“mukaanyes”

66.249.73.224 - - [10/Jul/2013:00:18:02 +0100] "GET /ne_demek/hatil HTTP/1.1" www,mankenresimleri,net "mankenresimleri,net" 404 4196 "-" "Mozilla/5.0 (兼容; Googlebot/2.​​1; +http://www.google.com/bot.html）“-”

/ne_demek/hatil 是针对 http; // nedir.anlambilim.net 的请求，但正在尝试从 http; // mankenresimleri.net 提供服务并返回 404；同样的情况在服务器上的其他域中也很常见且相互对应。

据我从日志中得出的结论，这种情况主要发生在 Google Bot、iPhone 和 Android 设备上。我无法在我的计算机上重现该错误，但可以从日志和 Google 网站管理员工具抓取错误报告中看到。

请帮忙。
