Problem getting mod_wsgi running with apache

Question

Not had any problems implementing this set up before, got a new server set up at home and wanted to work on some django projects.

Im using virtualenv with virtualenvwrapper, mod_wsgi module seems to be installed correctly. here is the vhost im using

<VirtualHost *:80> ServerName local.projectname.com ServerAlias local.projectname.co.uk WSGIDaemonProcess site-dev1 user=mike group=mike threads=20 python-path=/home/mike/envs/projectenv/lib/python2.6/site-packages WSGIProcessGroup site-dev1 WSGIScriptAlias / /home/mike/Sites/path/project/django.wsgi <Directory /home/mike/Sites/path/project> Options +Indexes FollowSymLinks +ExecCGI AllowOverride AuthConfig FileInfo Order allow,deny Allow from all </Directory> # Allow cross domain @font-face styles for Firefox <FilesMatch "\.(ttf|otf|eot)$"> <IfModule mod_headers.c> Header set Access-Control-Allow-Origin "*" </IfModule> </FilesMatch> ErrorLog /var/log/apache2/error.log LogLevel warn CustomLog /var/log/apache2/access.log combined </VirtualHost> 

When try to navigate to the project i get 500 internal server error, heres the out put from the apache error logs

[Sun Jul 24 08:46:32 2011] [error] [client 127.0.0.1] Traceback (most recent call last): [Sun Jul 24 08:46:32 2011] [error] [client 127.0.0.1] File "/home/mike/Sites/outsideline/queenonline/queenonline.wsgi", line 16, in <module> [Sun Jul 24 08:46:32 2011] [error] [client 127.0.0.1] from django.core.handlers.wsgi import WSGIHandler [Sun Jul 24 08:46:32 2011] [error] [client 127.0.0.1] ImportError: No module named django.core.handlers.wsgi 

I can import from django.core.handlers.wsgi import WSGIHandler in shell with out any errors, As i understand it the process and group of the WSGIdaemon should be the user and group owners of the files, i have also set my apache user and group to run as mike:mike to see if that would work

Im totally out of ideas now so if anyone can shed some light on this i will be eternally grateful!

Check the PYTHONPATH

To debug this problem you can output logging output from your .wsgi script to a file using a logger (Python logger). PYTHONPATH can be read inside Python using sys.path

 import sys log = open("/tmp/log.txt", "wt") # ghetto logging print >> log, sys.path # you'll see what you have PYTHONPATH when running the script 

Then you can check if Python can actually open the file

 import sys log = open("/tmp/log.txt", "wt") # ghetto logging try: f = open("/path/to/django/__init__.py", "rt") exception Exception, e: print >> log, str(e)
