C# debian上的nginx、mono和fastcgi网关不好

我正在为Linux的.NET替代mono而挣扎。这是我的元数据：

OS: Debian 7.6 alias Wheezy   (as virtual machine; host: Windows 7 Pro SP1)
nginx v1.6.1                  (installed from nginx repository)
mono v3.6.0                   (compiled from source)
mono-fastcgi-server4          (installed from Debian repositories)

nginx工作正常；我在没有单声道的情况下测试了它，所以这应该不是问题

当我在nginxserver配置中启用fastcgi部分时，问题就出现了：我得到了一个502坏网关

供您参考，这些都是我到目前为止编辑的配置文件。我认为这些是重要的：

/etc/nginx/conf.d/default.conf

server {
   listen        80;
   server_name   myserver.net;
   root          /var/www/myserver.net;
   index         index.html;

      location / {
         fastcgi_index   index.html;
         fastcgi_pass    127.0.0.1:9000;
         include         /etc/nginx/fastcgi_params;
      }
}

/etc/nginx/fastcgi_参数（除这两行外的原始参数）：

fastcgi_param PATH_INFO          "";
fastcgi_param SCRIPT_FILENAME    $document_root$fastcgi_script_name;

/etc/init.d/mono-fastcgi/myserver.net.webapp

实际上我不知道，为什么

&

必须在最后出现，但是如果没有它，命令将无法工作。有什么建议吗

我想这就是我能与你分享的所有信息。如果缺少什么，请指出，我会尽快添加信息

编辑：我忘记添加fastcgi.log和nginx日志了： /var/log/mono/fastcgi.log

只是一个疑问：

fastcgi-mono-server4

是否支持mono3.6？Mono3.6似乎是.NET4.5。我不认为这是问题所在，因为我甚至无法访问html页面。我的意思是，fastsgi服务器应该忽略html页面，不是吗？在将mono从2.8.10升级到3.10之后，我现在也遇到了同样的问题，没有改变任何其他内容，因此fastcgi-mono-server4和mono 3.6之间的版本不匹配
