Target WSGI script cannot be loaded as Python module


Question

I am trying to deploy mod_wsgi with apache to run a django application but I am getting an error 500 internal server error The apache logs shows:

[Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64] mod_wsgi (pid=16142): Exception occurred processing WSGI script '/home/user/bms/apache/django.wsgi'.
[Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64] Traceback (most recent call last):
[Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64]   File "/home/user/bms/apache/django.wsgi", line 13, in <module>
[Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64]     import django.core.handlers.wsgi
[Thu Jun 23 14:01:47 2011] [error] [client 152.78.95.64] ImportError: No module named django.core.handlers.wsgi

My apache virtual host is as follows:

<VirtualHost *:80>

    DocumentRoot /home/user/bms

    <Directory /home/user/bms>
        Order allow,deny
        Allow from all
    </Directory>

WSGIDaemonProcess bms user=user group=user processes=2 threads=25 python-path=/usr/local/lib/python2.7/site-packages


    WSGIProcessGroup bms

    WSGIScriptAlias / /home/user/bms/apache/django.wsgi

</VirtualHost>

And the referenced wsgi file in my app directory with 0777 permissions:

import os
import sys

path = '/home/user/bms'
if path not in sys.path:
    sys.path.append(path)

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

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

I heard that this may be because the apache user does not have the correct permissions. However I have no idea how to fix this. I also tried starting the deamon with the www-data user and this did not solve the issue.

EDIT:

I solved this by copying the virtual hosts file into the default one and then disabling the old one with a2dissite. I have no idea how I can do it "properly" and set it so apache goes to the virtual host I want it to though.

For me the problem was wsgi python version mismatch. I was using python 3, so:

$ sudo apt-get remove libapache2-mod-python libapache2-mod-wsgi
$ sudo apt-get install libapache2-mod-wsgi-py3

Warning from @alxs before you copy/paste these commands:
If there are python 2 projects running on the server that use wsgi and apache, the above commands will effectively shut them down.
