internal server Error while accessing django project

Question

I am trying to setup a python 2.7 + Django + virtualenv + mod_wsgi environment in my centos 6.3 server to run my python application through apache. But I am getting internal error while trying to access the application through apache. The error log shows the following.

============

[Fri Nov 15 04:20:30 2013] [error] [client 117.201.194.54] mod_wsgi (pid=20361): Target WSGI script '/var/www/html/djangosites/spark.wsgi' cannot be loaded as Python module.

[Fri Nov 15 04:20:30 2013] [error] [client 117.201.194.54] mod_wsgi (pid=20361): Exception occurred processing WSGI script '/var/www/html/djangosites/spark.wsgi'.

Fri Nov 15 04:20:30 2013] [error] [client 117.201.194.54] ImproperlyConfigured: Requested setting DEBUG, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

============

It is working fine when running as a test server.

======

(virtualenv)[root@lampserver spark]# python manage.py runserver 0.0.0.0:8080
Validating models...

Django version 1.6, using settings 'spark.settings'
Starting development server at 0.0.0.0:8080
Quit the server with CONTROL-C.

====

spark.wsgi file looks like the following.

===========

import sys
import site
import os

vepath = '/var/www/html/virtualenv/lib/python2.7/site-packages'

prev_sys_path = list(sys.path)

site.addsitedir(vepath)

sys.path.append('/var/www/html/djangosites')

new_sys_path = [p for p in sys.path if p not in prev_sys_path]

for item in new_sys_path:

    sys.path.remove(item)

sys.path[:0] = new_sys_path

from django.core.handlers.wsgi import WSGIHandler

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

application = WSGIHandler()

==============

Entries for wsgi in apache conf looks like the following

============

[root@lampserver djangosites]# cat /etc/httpd/conf.d/django.conf 


LoadModule wsgi_module modules/mod_wsgi.so
AddHandler wsgi-script .wsgi

WSGIScriptAlias / /var/www/html/djangosites/spark.wsgi

WSGIDaemonProcess spark processes=5 threads=15 display-name=%{GROUP}

WSGIProcessGroup spark

WSGIApplicationGroup %{GLOBAL}

WSGISocketPrefix /var/run/wsgi

=================

Apache is running as user "apache".

My project files and permissions are shown below.

===========

root@lampserver djangosites]# pwd

[root@lampserver djangosites]# ls

==================

Can anybody please identify the problem with my settings?

Answer 1

Could you start trying to change your wsgi with something more simple like:

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "spark.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Maybe this helps to detect the problem easier

Also use default wsgi file ( spark/wsgi.py ) instead of your spark.wsgi , of course by changing the WSGIScriptAlias directive in your apache config file. Here is an example of a simpler apache config file with your site settings, test this and let's me know:

WSGIPythonPath /var/www/html/djangosites:/var/www/html/virtualenv/lib/python2.7/site-packages
WSGIPassAuthorization On
WSGIScriptAlias / /var/www/html/djangosites/spark/wsgi.py

<Directory /var/www/html/djangosites/spark>
    <Files wsgi.py>
        Order allow,deny
        Allow from all
     </Files>
</Directory>

Answer 2

Add this line to your spark.wsgi file:

sys.path.append('/var/www/html/djangosites/spark')

Since your django site is located in that directory
