How to properly configure paths and permissions for python to deploy Django + mod_wsgi?

Question

The problem I encountered is my wsgi file, which cannot import wsgi handlers correctly.

/var/log/apache2/error.log reports:

ImportError: no module named django.core.handlers.wsgi

A Google search results in a couple of results, mainly related to permission errors, because www-datait cannot read certain files and / or the pythonpath is incorrect. Some of the solutions are vague or just do not work in my circumstances.

Background information ..

My / usr / lib directory ..

/usr/lib/python2.4
/usr/lib/python2.5
/usr/lib/python2.6
/usr/lib/python-django

The default python version is 2.5.2. If I open the interpreter as a regular user, I can import django.core.handlers.wsgino problem.

www-data, python , django.core.handlers.wsgi .

bashrc PYTHONPATH , django...

export PYTHONPATH=/home/meder/django-sites/:$PYTHONPATH

, :

django-sites/
   test

test - , django-admin createproject.

:

<VirtualHost *:80>
    ServerName beta.blah.com
    WSGIScriptAlias / /home/meder/django-sites/test/apache/django.wsgi
    Alias /media /home/meder/django-sites/test/media/
</VirtualHost>

/home/meder/django-sites/test/apache/django.wsgi:

import os, sys

sys.path.append('/usr/local/django')
sys.path.append('/home/meder/django-sites')
sys.path.append('/home/meder/django-sites/test')
os.environ['DJANGO_SETTINGS_MODULE'] = 'test.settings'

import django.core.handlers.wsgi

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