Hi everyone!
Even though i compile mod_wsgi with "--with-python=/path/to/custom/
python/executable", the system python executable is being used to run
the wsgi app, not the custom one. Is there any setting i'm
misconfiguring in httpd.conf or anywhere else?
If the the Django framework (python-django Ubuntu package) is not
installed in the system python, the url, triggering the django wsgi
app, ends up with Apache's internal error and `"ImportError: No module
named django.core.handlers.wsgi"` message in apache's error logs. If
django is installed in the system path, it ends up with django pretty
error page:
ImportError at /
No module named djangosphinx.models
Request Method: GET
Request URL: http://127.0.0.1:8001/djangoapp/
Exception Type: ImportError
Exception Value:
No module named djangosphinx.models
Exception Location: /home/toinbis/Desktop/programming/project/src/
tsd/core/models.py in <module>, line 3
Python Executable: /usr/bin/python
So clearly the problem is with using wrong python executable to run
the wsgi app (djangosphinx is a module which is successfully imported
with the zc.buildout custom generated python executable).
More background details:
Am deploying custom nginx + apache(mod_wsgi) + supervisor + mysql +
python + django + php + phpmyadmin + wordpress setup using zc.buildout
(http://buildout.org). Buildout.cfg details:
[apache]

But usually that just caused apache to fail during the start,
generating error(s):

application = django.core.handlers.wsgi.WSGIHandler()
Possibly-relevant settings in httpd.conf (these are the only two
modules being loaded. Rest of the settings doesn't seem relevant to
the given problem):
LoadModule php5_module modules/libphp5.so
LoadModule wsgi_module modules/mod_wsgi.so
Thanks in advance for any ideas and suggestions how to make the custom
python executable (which, itsefl, is just a wrapper script for system
python, with several added python path dirs) run the mod_wsgi app!
