Nginx + Gunicorn + Django1.5 - connect() не удалось (111: соединение отказано) при подключении к восходящему потоку

Question

Я получаю это при доступе к моему домену: я вижу, что отображается мой шаблон по умолчанию, ошибка http500 error django.

У меня есть gunicorn установки:

command = '/usr/local/bin/gunicorn' 
logfile = "/home/ubuntu/virtualenv/myapp/error/gunicorn.log" 
loglevel = "info" 
pythonpath = '/home/ubuntu/virtualenv/myapp' 
bind = '127.0.0.1:8001' 
workers = 3 

У меня есть Nginx конфигурации:

server { 
     listen  80; 
     server_name *.myapp.com; 
     access_log /home/ubuntu/virtualenv/myapp/error/access.log; 
     error_log /home/ubuntu/virtualenv/myapp/error/error.log warn; 
     connection_pool_size 2048; 

     fastcgi_buffer_size 4K; 
     fastcgi_buffers 64 4k; 

     root /home/ubuntu/virtualenv/myapp/homelaunch/; 

     location /static/ { 
      alias /home/ubuntu/virtualenv/myapp/homelaunch/static/; 
      #alias /static/; 
      #root /home/ubuntu/virtualenv/myapp/homelaunch/; 
     } 

     location/{ 
      proxy_pass http://127.0.0.1:8001; 
      proxy_set_header Host $host; 
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

     } 
    }

в error_log этого Nginx Я вижу:

2013/10/25 00:31:49 [error] 1840#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xxx.xx.xxx, server: myapp.com, request: "GET/HTTP/1.1", upstream: "http://127.0.0.1:8001/", host: "myapp.com" 

в access_log этого Nginx конфигурации я вижу:

xx.xxx.xx.xxx - - [25/Oct/2013:00:31:49 +0000] "GET/HTTP/1.1" 502 173 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0" 

Я уже пытался читать в проблему и увидел, добавив:

fastcgi_buffer_size 4K; 
    fastcgi_buffers 64 4k; 

в конфигурацию nginx может помочь в этом, но это не так.

Я немного смущен тем, как я могу отладить это отсюда? Может кто-нибудь помочь?

спасибо.

Измените свой settings.py файл так, что allowed_hosts = [ «домен»] (или [ «*»], чтобы получить его работу)
