Nginx + Gunicorn + Django1.5 – connect () a échoué (111: connexion refusée) lors de la connexion en amont

Je reçois cela lors de l’access à mon domaine: je vois mon modèle d’erreur django http500, par défaut, affiché.

J’ai la configuration gunicorn :

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 

J’ai nginx config:

 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; #proxy_set_header X-Forwarded-Host $server_name; #proxy_set_header X-Real-IP $remote_addr; add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"'; } }

dans error_log de ce nginx je vois:

 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" 

dans access_log de cette configuration nginx je vois:

 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" 

J’ai déjà essayé de lire dans le problème et j’ai vu append:

  fastcgi_buffer_size 4K; fastcgi_buffers 64 4k; 

à la configuration nginx peut aider cela, mais ce n’est pas le cas.

Je suis un peu confus sur la façon dont je peux déboguer ceci à partir de là? Quelqu’un peut-il aider?

Je vous remercie.
