我在 centos 6.2 上运行的 nginx 1.0.15 网络服务器设置了 mono 2.11。我从源代码构建它，xps2、xps4 和 fastcgi-mono-server2 按预期工作。问题是当我尝试运行 fastcgi-mono-server4 时。当我跑步时：
fastcgi-mono-server4 /applications=site:/:/srv/www/html/ /socket=tcp:127.0.0.1:9000 /loglevels=Debug /printlog=true
这是我从 fastcgi-mono-server2 得到的：

我看不出我做错了什么。任何帮助都会很棒。
编辑：返工，现在我收到错误网关的 502 错误。日志看起来仍然一样。
查看我的 Nginx 错误日志，发现许多这样的条目：
2012/06/18 13:56:01 [error] 3108#0: *4 connect() failed (111: Connection refused) while connecting to upstream, client: 192.168.128.121, server: site, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "site"
无论 fastcgi-mono-server4 是否打开，我都会得到相同的响应。它现在总是显示 502 错误。
