基本的hello.wsgi工作正常。 其他的django应用程序也完美地使用完全相同的virtualenv版本。
mod_wsgi挂起~10分钟（!!!），我什么都看不到问题（logleveldebugging）：

Apacheconfiguration也没有什么有趣的。 相同的configuration在其他服务器上工作。

没有什么有趣的wsgi ：
import os, sys activate_this = '/var/www/prj.project-dev/venv/bin/activate_this.py' execfile(activate_this, dict(__file__=activate_this)) sys.path = [ '/var/www/prj.project-dev/venv/lib/python2.7/site-packages/', '/var/www/prj.project-dev/venv/prj/', '/var/www/prj.project-dev/venv/', ] + sys.path os.environ['DJANGO_SETTINGS_MODULE'] = 'prj.settings' import django.core.handlers.wsgi #from raven.contrib.django.middleware.wsgi import Sentry application = django.core.handlers.wsgi.WSGIHandler() #application = Sentry(django.core.handlers.wsgi.WSGIHandler())
我的问题是：我怎么能得到它挂起的真实原因？
这由mod_wsgi文档覆盖。
http://code.google.com/p/modwsgi/wiki/ApplicationIssues#Python_Simplified_GIL_State_API
简而言之，你可能使用了一个Python扩展模块，这个扩展模块在Python子解释器中没有被正确的实现。 在进行阻塞操作时，扩展模块不能正确释放GIL。 两者都可能导致解释器死锁。
使用文档中的解决方案，看看是否有帮助。
<VirtualHost *:80> serverName localhost serverAlias localhost serverAdmin raghav@xyz.com <Directory /var/www/mysite/mysite> AddHandler wsgi-script .py Options +ExecCGI </Directory> DocumentRoot /var/www/mysite WSGIDaemonProcess myproject python-path=/var/www/mysite:/var/www/environ/lib/python2.7/site-packages #WSGIProcessGroup mysite WSGIScriptAlias / /var/www/mysite/mysite/wsgi.py WSGIApplicationGroup %{GLOBAL} <Directory /var/www/mysite/mysite/> order deny,allow Allow from all </Directory>
我也有同样的错误，我已经通过使用这种配置解决了这个问题。
还要/etc/apache2/apache.config下行添加到/etc/apache2/apache.config
#WSGIPythonPath /var/www/mysite
我知道这个线程是三岁，但当我有类似的问题，我偶然发现，所以我想我会添加我的解决方案。 在我的情况下，这是虚拟环境中的东西，需要在Apache中启用mod_ssl，即使没有一个站点使用SSL（以及他们这样做，但在别处终止）。 所以
a2enmod ssl service apache2 restart
修复。
通过上面的答案挖掘。 我必须将进程数量从5设置为1.还要使用多工人mpm。
