Use Apache 2 + mod_wsgi for Python app

Question

I'm trying to use Apache 2 + mod_wsgi for my Python app. But get an error:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, [email protected] and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.

My configurations: Ubuntu 12.04, Apache2, Python3.3, Django 1.6, libapache2-mod-wsgi-py3.

My settings.

import os
import sys  
sys.path.append('/home/ube/www/test.local/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'test_site.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

I haven't forgotten:

sudo a2ensite test.local
sudo service apache2 restart

Error log says:

Where is Django installed? Does the Apache user have read rights to that location? — Daniel Roseman
Django installed in /usr/local/lib/python3.3/dist-packages. The test site is located in the /home/ube/www/test.local. Rights to this a folder: 0775/drwxrwxr-x. — Mikhail Shchedrakov

Solution in my case:

import os
import sys  
sys.path.append('/home/ube/www/test.local/test_site/')
sys.path.append('/home/ube/www/test.local/')
sys.path.append('/home/ube/www/')
sys.path.append('/usr/local/lib/python3.3/dist-packages')

os.environ['DJANGO_SETTINGS_MODULE'] = 'test_site.settings'

from django.core.handlers.wsgi import WSGIHandler
application = WSGIHandler()

I added more sys.path =).
