Gevent-socketio nginx uwsgi does not work together on the development server

I am running a django project that uses gevent-socketio.

For some reason, on my development server, all my requests to web servers return a 101 pending message in which the socket will begin cyclic movement through all other protocols that will lead to the pending status.

Error in my wwsgi logs:

 2013/05/23 16:09:08 [error] 14485#0: *85 upstream timed out (110: Connection timed out) while reading upstream, client: xxxx, server: dev.proj.co, request: "GET /socket.io/1/xhr-polling/116404981619?t=1369325348489 HTTP/1.1", upstream: "http://127.0.0.1:4042/socket.io/1/xhr-polling/116404981619?t=1369325348489", host: "dev.proj.co", referrer: "http://dev.proj.co/map/bycon/" 

Locally, I do not have this problem. I start the server using python run.py

run.py in the local environment

 #!/usr/bin/env python import os import sys from gevent import monkey monkey.patch_all() import django.core.handlers.wsgi from socketio.server import SocketIOServer import os PORT = 8000 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "proj.settings") application = django.core.handlers.wsgi.WSGIHandler() PROJECT_DIR = os.path.realpath(os.path.dirname(__file__)) sys.path.insert(0, PROJECT_DIR) sys.path.insert(0, os.path.join(PROJECT_DIR, "chat")) if __name__ == '__main__': SocketIOServer(('', PORT), application, resource="socket.io").serve_forever() 

On my development server where the error occurred, I have the following settings:

nginx.conf

 worker_processes auto; events { worker_connections 1024; } http { include mime.types; default_type application/octet-stream; sendfile on; keepalive_timeout 65; gzip on; upstream django { server 127.0.0.1:4042; } server { listen 80; server_name dev.proj.co; charset utf-8; access_log /var/log/nginx/myproj_dev.access.log; error_log /var/log/nginx/myproj_dev.error.log; location /media/ { alias /var/www/dev/myproj/releases/myproj_public/media/; error_page 404 = /404; expires 30d; } location /static/ { alias /var/www/dev/myproj/releases/myproj_public/static/; error_page 404 = /404; expires 30d; } location / { proxy_pass http://127.0.0.1:4042; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } } } 

uwsgi_dev.ini

wsgi_dev.py

 import os from gevent import monkey monkey.patch_all() from socketio.server import SocketIOServer os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myproj.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application() PORT = 4042 SocketIOServer(("127.0.0.1", PORT), application, \ resource="socket.io").serve_forever() 

Additional Information:

 I'm using uwsgi 1.9.6, gevent-websocket 0.3.6, greenlet 0.4.0 and the dev version of gevent(-e git://github.com/surfly/ gevent.git@e2f51c1358e88b60e45d1daf8ee263da64066576 #egg=gevent-dev) and gevent-socketetio (-e git://github.com/abourget/ gevent-socketio.git@aeece7038b0052ddf6b4228857e4d7a67a6242f2 #egg=gevent_socketio-dev) [ root@li476-12 ~]# nginx -v nginx version: nginx/1.4.1

To support web maps, you need the latest version of nginx (1.4.x). If you are using older versions, you will not be able to launch the websocket channel

SocketIOServer will never start when the django WSGI file is run as a module, so __name__ is not __main __

In addition to this, the logic is erroneous, as SocketIOServer will capture uWSGI, blocking the yorur django application.

I suggest you run SocketIOServer from a separate script using --attach-daemon uWSGI

(and obviously install uWSGi on a different port)

Disable threads in UWSGI.

You have a global interpreter lock problem

enable-threads = True <- I think the problem is here, try False
