Python version for mod_wsgi

Question

how can I change the default version mod_wsgi uses?

I am using Debian 5 with Apache 2.

Answer 1

Look for /usr/lib/apache2/modules/mod_wsgi.so*, at least on ubuntu I have:

/usr/lib/apache2/modules/mod_wsgi.so -> mod_wsgi.so-2.6
/usr/lib/apache2/modules/mod_wsgi.so-2.5
/usr/lib/apache2/modules/mod_wsgi.so-2.6

If you change the symlink, you change the default mod_wsgi.

An alternative is to look in /etc/apache2/mods-enabled/wsgi.load, for me that's just one line:

LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so

If you point that at one of those mod_wsgi.so-2.x files, you've changed the default version.

Answer 2

When you say different version you mean Python 2.5 vs 2.6, then you must install mod_wsgi package binary compiled against Python 2.5, or compile mod_wsgi from source code yourself against the Python 2.5 version. See notes about --with-python option in:

Answer 3

you should look into using virtualenv. I think that is what you are looking for
