geevent - sockettio nginx uwsgi不能在开发服务器上一起工作

Question

我正在运行一个使用geevent -socketio的django项目。

由于某种原因，在我的开发服务器上，我所有的websockets请求都返回一个101 pending消息，在这个消息中，sockettio将开始循环通过所有其他协议，从而导致pending状态。

我的uwsgi日志中的错误是:

2013/05/23 16:09:08 [error] 14485#0: *85 upstream timed out (110: Connection timed out) while reading upstream, client: x.x.x.x, 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/"

在本地，我没有这个问题。我使用python run.py

启动服务器

run.py on my 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()

在我的开发服务器上，错误正在发生，我有以下设置:

nginx.conf

worker_processes  auto;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;

    gzip  on;

        server 127.0.0.1:4042;
    }

    server {
        listen       80;
        server_name dev.proj.co;

        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";
        }
    }
}

其他信息:

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

Answer 1

对于websockets支持，您需要最新版本的nginx (1.4.x)。如果你使用旧版本，你将无法启动websocket通道

Answer 2

当你将WSGI django文件作为一个模块运行时，SocketIOServer将永远不会运行，所以__name__不是__main__

除此之外，这个逻辑是错误的，因为SocketIOServer将接管uWSGI阻塞你的django应用。

我建议您使用uWSGI的——attach-daemon从一个单独的脚本运行SocketIOServer

(显然把uWSGi放在不同的端口上)

Answer 3

禁用UWSGI中的线程。

你有问题"全局解释器锁"

enable-threads = True <-我认为这里有问题，试试False
