website using default python interpreter instead of install virtualenv interpreter

I have installed python 2.7 on centos.

I have created and activated a virtualenv associated with this interpreter.

My path looks like this:

/home/ec2-user/django-venv/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/opt/aws/bin:/home/ec2-user/bin

When I hit my website i get the following error indicating that it is using the old version of python:

mod_wsgi (pid=19386): Exception occurred processing WSGI script '/var/www/html/-django//wsgi.py'.
 Traceback (most recent call last):
 File "/var/www/html/-django//wsgi.py", line 23, in <module>
   from django.core.wsgi import get_wsgi_application
 File "/usr/lib/python2.6/site-packages/django/core/wsgi.py", line 2, in <module>
   from django.core.handlers.wsgi import WSGIHandler
 File "/usr/lib/python2.6/site-packages/django/core/handlers/wsgi.py", line 11, in <module>
   from django import http
 File "/usr/lib/python2.6/site-packages/django/http/__init__.py", line 2, in <module>
   from django.http.request import (HttpRequest, QueryDict,
 File "/usr/lib/python2.6/site-packages/django/http/request.py", line 11, in <module>
   from django.conf import settings
 File "/usr/lib/python2.6/site-packages/django/conf/__init__.py", line 9, in <module>
   import importlib
 ImportError: No module named importlib

I created the the virtualenv like this:

virtualenv --python=/usr/local/bin/python2.7 django-venv

I then activated it like this:

source django-venv/bin/activate

When i initiate "which python" I get the following output:

~/django-venv/bin/python

My apache httpd.conf entry looks like this:

Alias /static/ /var/www/html/django/shared/static/

<Directory /var/www/html/django/shared/static/>
Order deny,allow
Allow from all
</Directory>


WSGIScriptAlias / /var/www/html/django/wsgi.py
WSGIPythonPath /var/www/html/django

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

But I still get the error above that it is using the old python version of 2.6

How can I have my site use this virtualenv which points to the correct place?

I just use the wsgi.py file generated by manage.py startproject and then put something like this in my httpd conf file:

WSGIScriptAlias / /full/path/to/wsgi.py
WSGIPythonPath /full/path/to/django/project:/full/path/to/django-venv/lib/python2.7/site-packages

The official docs cover this.

If you just run it in the shell, that only affects that shell session, and doesn't even persist between logins, let alone affecting any system-wide services like Apache.

Normally you would put something in your wsgi.py:

activate_this = '/path/to/virtualenv/bin/activate_this.py'
execfile(activate_this, dict(__file__=activate_this))
