Apache Wsgi virtualHost, Django virtual env “no module named django.core.wsgi”

Question

I have seen plenty of previous messages related to my problem, but no answer could get rid of my "500 Server internal Error" so I try to post my conf to get help.

Error Message:

My django app do not load in apache wsgi mode, I tried many solutions but still don't work. Here is my confs files : Virtual host :

<VirtualHost *:80>

ServerName dev.www.waves.com
ServerAlias www.waves.com
ServerAdmin [email protected]

DocumentRoot /home/www/waves
Alias media/ /home/www/waves/media/
Alias static/ /home/www/waves/static/

<Directory /home/www/waves>
   Require all granted
</Directory>

<Directory /home/www/waves/staticfiles>
   Require all granted
</Directory>

<Directory /home/www/waves/media>
   Require all granted
</Directory>

WSGIDaemonProcess waves python-path=/home/marc/.virtualenvs/waves/lib/python2.7/site-packages:/home/www/waves
WSGIProcessGroup waves
WSGIScriptAlias /waves /home/www/waves/waves_services/wsgi.py

<Directory /home/www/waves/waves_services>
  <Files wsgi.py>
    Require all granted
  </Files>
</Directory>

<Directory /home/marc/.virtualenvs/waves/lib/python2.7/>
Require all granted
</Directory>

My wsgy.py content :

from __future__ import unicode_literals
import os
import sys
import site

print sys.path
from django.core.wsgi import get_wsgi_application
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "waves_services.settings.production")
application = get_wsgi_application()

I traced to sys.path content in apache error log, and the virtualenv in in sys.path. Django is installed in this virtualenv (I had first tried to install django 'globally' but the error was just moved to the first 'application specific' import : environ contained in my settings file. The virtual env was created with virtualenvwrapper (any impact ?)

I tried as well to change ownership of virtualenv file, changed 'execution' flag as well, but still I get this ... 500 Server Error.

I would be grateful to get a clue of what is happening ! thanxs

Hello, yes django is installed in a virtualenv. To pe more precise here is a sample of my sites-packages ll result: django mptt Django-1.9.6.dist-info django_cors_headers-1.1.0-py2.7.egg-info django_countries django_countries-3.4.1.dist-info django_crontab django_debug_toolbar-1.4.dist-info django-eav.egg-link ... — marcoooo
Is that virtualenv accessible to apache? this is often a problem — e4c5
Hello, do you mean configured in virtual host <Directory> or file permissions ? Permissions are set as follow on virtual env dir : 775 for dirs, 644 for files, all marked in www-data group, but owned by me (ie marc) — marcoooo
No, what is mean is does the apache user have access to the virtualenv folder — e4c5
Ok, if it is only related to 'apache' user (www-data), I changed group of my virtualenv directory to www-data, with no change in my error. still can't find django core module. I even tried to change ownership to www-data, (in this case, I think I won't be able to make any more pip install in this virtual env from 'marc' user?) stille same error. — marcoooo

Several things to check for.

Make sure that the virtualenv has django (pip freeze | grep django)
Check if apache user can access the virtualenv by checking the folder permissions
if you are using apache 2.4 + change the following

Order deny,allow Allow from all

to

Require all granted

Edit suggested by @marcoooo (OP) : don't put virtualenv base dir under any home dir which do not have 'x' flag, apache www-data user won't be able to activate the virtualenv either.... Many thanxs to e4c5 for his help, and saved my day (and nights)
