Question

我正在尝试将Django项目的升级从1.4升级到1.8。我的网站在本地运行没有任何问题。但是，当我部署升级的代码时，我得到一个502坏网关。该站点使用Django 1.4在服务器上运行，没有任何问题。

1.4版本的代码使用了Gunicorn和Supervisor。我无法使用Gunicorn运行升级的代码，因此我尝试使用uWsgi，这导致我遇到了同样的问题。

我在同一台服务器上使用Django 1.4的其他网站工作正常。

我无法在任何日志中看到任何有用的错误，我看到的唯一错误是在Nginx日志中：

2016/02/24 10:32:16 [error] 15475#0: *52 upstream prematurely closed connection while reading response header from upstream, client: [IP address], server: myapp.*, request: "GET /api/get_campaign/ HTTP/1.1", upstream: "http://unix:///var/run/supervised-sockets/myapp-uwsgi.sock:/api/get_campaign/", host: "[site-name]"

Nginx配置：

upstream django {
        server unix:///var/run/supervised-sockets/myapp-uwsgi.sock;
    }

server {
    listen 80;

    server_name myapp.*;

    access_log /var/log/nginx/myapp_access.log;
    error_log /var/log/nginx/myapp_error.log notice;

   # rewrite URLs of the form  static/.*/*.gz to non .gz then gzip_static module will check
    # for the compressed version on disk. Round about method to get around django-compressor
    # adding the .gz extension
    rewrite /static/(.*)\.(css|js)\.gz$ /static/$1.$2 last;
    rewrite /media/(.*)\.(css|js)\.gz$ /media/$1.$2 last;

    location /static/CACHE/ {

        root /srv/myapp/releases/current/myapp/myapp/assets/;

        expires max;
        break;
    }



    location /favicon.ico {
        root /srv/myapp/releases/current/myapp/myapp/assets/static/img/;
    }

    location /static/ {

        root /srv/myapp/releases/current/myapp/myapp/assets/;
    }

    location /media/ {
        root /srv/myapp/shared/;
    }

    location / {
       uwsgi_pass django;
       include /srv/myapp/releases/current/myapp/uwsgi_params;
       proxy_set_header HOST $http_host;
       #proxy_pass http://unix:/var/run/supervised-sockets/myapp-uwsgi.sock;
       proxy_pass http://myapp;
       proxy_buffering off;  # no need as services are local
       proxy_connect_timeout 3000s;
       proxy_read_timeout 3000s;
    }

这是我的uWsgi ini文件：

[uwsgi]

# Django-related settings
# the base directory (full path)
chdir           = /srv/myapp/releases/current/myapp
# Django's wsgi file
module          = myapp_wsgi:application
# the virtualenv (full path)
home            = /srv/myapp/
#virtualenv = myapp
# process-related settings
# master
master          = true
# maximum number of worker processes
processes       = 2
# the socket (use the full path to be safe
socket          = /var/run/supervised-sockets/myapp-uwsgi.sock
# ... with appropriate permissions - may be needed
chmod-socket = 666
chown-socket = myapp
# clear environment on exit
vacuum          = true
buffer-size=32768
#die-on-term = true
#wsgi-file = myapp/myapp_wsgi.py

当我运行uWsgi时，这是输出：

这是Supervisor使用的Gunicorn配置：

这是我的Django wsgi文件：

import os
import sys

THIS_DIR = os.path.dirname(os.path.realpath(__file__))

sys.path.insert(0, os.path.join(THIS_DIR, "/"))
sys.path.insert(0, os.path.join(THIS_DIR, "myapp/apps"))
sys.path.insert(0, os.path.join(THIS_DIR, "myapp/lib"))

os.environ["DJANGO_SETTINGS_MODULE"] = "myapp.settings"

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

任何帮助都非常感谢，因为我已经研究了一段时间了。

谢谢
