Nginx，fastcgi，proxy_pass

Question

有2个域： main.domain.com和sub.domain.com

所以我需要将sub.domain.com代理传递给main.domain.com/somepath ，但是现在我正在捕获main.domain.com和sub.domain.com ：

[错误] 27961＃27961：* 14上游超时（110：连接超时），同时从上游读取响应头，客户端：ip.ip.ip.ip，服务器：sub.domain.com，请求：“ GET / HTTP /1.1“，上游：” http://127.0.0.1:8000/ “，主机：” sub.domain.com“

我的nginx配置看起来像：

    server {
        listen 80;
        client_max_body_size 1000m;
        charset utf-8;

        server_name main.domain.com;

        location / {
             fastcgi_pass 127.0.0.1:8000;
             include fastcgi_params;
             fastcgi_param PATH_INFO $fastcgi_script_name;
             fastcgi_param REQUEST_METHOD $request_method;
             fastcgi_param QUERY_STRING $query_string;
             fastcgi_param CONTENT_TYPE $content_type;
             fastcgi_param CONTENT_LENGTH $content_length;
             fastcgi_pass_header Authorization;
             fastcgi_intercept_errors off;
        }
    }

   server{
        listen 80;
        server_name sub.domain.com;

        location / {
            proxy_pass http://127.0.0.1:8000/somepath;
            proxy_set_header Host main.domain.com;
        }
    }
