Why doesn't Apache run the right version of Python?

Question

Django

Hello!
I have two versions of python 2.6 and 2.7. Old Django project running 2.6 + django 1.3
Virtualenvs installed. Just the old site works in it + installed the environment there only by specifying the version of python 2.7
+ activated it.
HAVE MADE THESE SETTINGS:

NameVirtualHost *:82
Listen 82
<VirtualHost *:82>
    ServerAdmin [email protected]
    ServerName localhost

    DocumentRoot /var/www

    LogLevel warn
    ErrorLog /home/adminko/projects/test/error_log

    WSGIDaemonProcess test processes=2 maximum-requests=500 threads=1
    WSGIProcessGroup test

    WSGIScriptAlias / /home/adminko/projects/test/django.wsgi

    Alias /media/ /home/adminko/projects/test/media/
    Alias /admin-media/ /home/adminko/.virtualenvs/test/lib/python2.7/site-packages/django/contrib/admin/media/

    <Directory /home/adminko/projects/test/media>
        Order deny,allow
        Allow from all
    </Directory>
    <Directory /home/adminko/.virtualenvs/test/lib/python2.7/site-packages/django/contrib/admin/media>
        Order deny,allow
        Allow from all
    </Directory>

</VirtualHost>

DJANGO.WSGI

import os
import sys

PROJECT_ROOT = os.path.dirname(__file__)
PYTHON_LIBS = '/home/adminko/.virtualenvs/test/lib/python2.7/site-packages'

sys.path.extend((PROJECT_ROOT,PYTHON_LIBS,os.path.dirname(PROJECT_ROOT)))

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

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

SUMMARY: My site is running with Django 1.3 + Python 2.6
In settings.py, I deleted the lines
MIDDLEWARE_CLASSES = (
) to see what was going on, just an error 500 was always

Help, please.

Answer 1

Of course, I apologize for the "stupid" question, but why use all these shamanic dances with tambourines, with virtual environments and version managers if virtual machines have long been invented? You create an ideally clean environment for yourself in a virtual machine with the necessary versions of all software and enjoy life. Or is there something I don't know?

Answer 2

mod_wsgi runs the python (libpython) it was built with.
the link to the library is fixed directly in .so and nothing can be done about it.
you can try to build two versions of mod_wsgi and somehow play shaman with directives.
