我一直在尝试使用MOD_WSGI将DJANGO-REST WS集成到Apache中，但是在尝试应用所有调试技术和不同的wsgi脚本一段时间后，帮帮我。DJANGO-REST，MOD_WSGI和APACHE集成问题
Server版本：阿帕奇/ 2.2.22（Ubuntu的） 的Python 2.7.3（默认情况下，2014年2月27日，19点58分35秒） mod_wsgi的版本：3.3
目前我WSGI文件如下：
"""

It exposes the WSGI callable as a module-level variable named ``application``.

import os, sys
sys.path.append('/usr/local/ZigHomeWS')
sys.path.append('/usr/local/ZigHomeWS/zighome_rest')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "zighome_rest.settings")
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
和我的虚拟主机被配置如下：
<VirtualHost *:80>

我必须承认，添加“/usr/local/lib/python2.7/site-packages/django”只是一种绝望的措施，最终导致无所事事。
我应该提到的一点是，尽管它对解决方案没有任何影响，但核心系统实际上是一个我用SWIG包装的C++系统。
不用说，它正在使用Django-REST开发环境。
最后但并非最不重要的，如果在WSGI脚本文件更改这两行：
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
这些：
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
这反而崩溃日志中提供的堆栈跟踪文件：
[Sat Sep 27 19:44:10 2014] [error] [client X.X.X.X] Premature end of script headers: django.wsgi
我最终应用了推荐的调试技术，但不幸的是，牛逼非常有帮助的，因为GDB的堆栈跟踪只给我：
(gdb) cont

调查：
所以...我刚刚意识到的东西。
从我从几个网站阅读在网络上，我应该是真的使用这个电话：
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
的WSGI脚本。由于这两行代码一直在崩溃，我无法快速完成任务，所以我记得打电话给我创建的任何其他Web服务和VOILA！有用。 （不知道为什么我以前没有尝试过......固执我猜）
现在，两个网络服务之间的主要区别之一就是它只解析一些XML文件并添加数据到sqlite3数据库和另一个（崩溃的）数据库启动整个系统，这意味着创建多个线程等等。
因此，我现在正在寻找任何线程相关的记录问题，我可以找到modwsgi。
我希望你能为我提供一些帮助
谢谢
请用您的设置文件更新问题。 – 2014-09-28 12:21:01
我编辑了添加settings.py文件配置请求的问题。 – cvicente 2014-09-28 12:31:48
从错误看来，你应该在某些文件中使用'gettext_lazy'时使用'gettext';从你的设置不明确。但是，检查您的其他应用程序。如果你从'INSTALLED_APPS'注释掉'rest_framework'，你还会得到错误吗？ – 2014-09-28 13:03:51
