apache - mod_wsgi and multiple installations of python

Question

This is kind of a continuation of this question, but it has deviated so I started a new one. I'd like to use Python 2.5 instead of OS X's default 2.6. I've set this up for my terminal and whatnot, but whenever apache runs it gives me the following error output:

[Thu Jun 23 00:01:42 2011] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
[Thu Jun 23 00:01:42 2011] [warn] mod_wsgi: Compiled for Python/2.5.4.
[Thu Jun 23 00:01:42 2011] [warn] mod_wsgi: Runtime using Python/2.6.1.
[Thu Jun 23 00:01:42 2011] [notice] Digest: generating secret for digest authentication ...

I've set WSGIPythonPath to match what sys.path gives me in the python shell:

WSGIPythonPath /System/Library/Frameworks/Python.framework/Versions/2.5

Still no luck. Ideas?

Answer 1

You should use the following directives depending on which version of mod_wsgi you use

For mod_wsgi 1.x:

WSGIPythonExecutable /path/to/python/2.5/exe

For mod_wsgi 2.x:

WSGIPythonHome /path/to/python/2.5/exe/directory

The WSGIPythonPath is just intended to add your own libraries to the Python Path in the WSGI context.
