uWSGI 和 Django 1.4 - 网关错误且无错误

我在让 Django 和 uWSGI 在 Ubuntu (12) 上顺利运行方面遇到了麻烦。似乎 wsgi 正在加载，然后应用程序立即崩溃。uwsgi 日志都没有给我任何参考信息。我使用的是标准 Django 1.4 wsgi，uwsgi 配置如下：

[uwsgi]
project = djangoproject
base_dir = /home/www/mywebsite.com

uid = www-data
gid = www-data
plugins = http,python

processes = 4
harakiri = 60
reload-mercy = 8
cpu-affinity = 1
max-requests =  2000
limit-as = 512
reload-on-as = 256
reload-on-rss = 192
no-orphans = True
vacuum = True
master = True

logto = /var/log/uwsgi/%n.log
catch-exceptions

virtualenv = %(base_dir)/venv
chdir = %(base_dir)
module = %(project).wsgi

socket = /run/uwsgi/%n.sock
chmod-socket = 666

这是我的日志文件的内容：

我看不到任何可以解释应用程序崩溃原因的内容。我还向 wsgi.py 添加了打印语句，以确保它正确加载。

作为参考，这是我的 wsgi：

import os

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "djangoproject.settings")

# This application object is used by any WSGI server configured to use this
# file. This includes Django's development server, if the WSGI_APPLICATION
# setting points here.
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

我不认为 uWSGI（或 Django）崩溃了。uWSGI 在死亡/重新加载时非常冗长，而你的标题报告了“坏网关”错误，这是另一回事。检查你的网络服务器日志，也许是一些配置错误
