你好，我找到了很多关于这个错误的东西，但对我来说仍然没有任何作用。很抱歉再次询问。:-)
错误（505）日志：
[Wed Aug 28 19:02:59 2013] [error] [client 123] mod_wsgi (pid=19305): Exception occurred processing WSGI script '/usr/local/www/foo-app/foobar/wsgi.py'.

我的 wsgi.py 文件：
import os
import sys
# We defer to a DJANGO_SETTINGS_MODULE already in the environment. This breaks
# if running multiple sites in the same mod_wsgi process. To fix this, use
# mod_wsgi daemon mode with each site in its own daemon process, or use
# os.environ["DJANGO_SETTINGS_MODULE"] = "foobar.settings"
sys.path.append('/usr/local/www/foobar-app/foobar')
sys.path.append('/var/www')
sys.path.append('/var/www/foobar')
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "foobar.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()
本地所有工作。
感谢您的每一个帮助！
伟大的
