This is a simple guide to install/upgrade mod_python on a Plesk RHEL box, running Apache 2.0.x. You need to have at least Python version 2.2.1 installed for this to work.

I could not get mod_python version 3.2.8 running at the time of writing.

1. Download and extract mod_python:
   

   cd /usr/local/src
wget http://apache.mirrors.pair.com/httpd/modpython/mod_python-3.1.4.tgz
tar zxvf mod_python-3.1.4.tgz

2. Configure & install mod_python
   

   cd mod_python-3.1.4
./configure --with-apxs=/usr/sbin/apxs (check where your apxs is by typing: locate apxs)
make
make install

3. Configure Apache:
   

   vi /etc/httpd/conf.d/pyhton.conf

   Locate your LoadModule – section and add the following line under the others:

   LoadModule python_module modules/mod_python.so

4. Installation done, now time for testing:

   First go to a publicly accessible directory. Make a test directory for mod_python by typing:

   mkdir python

   Now open vi and write the following lines:

   AddHandler python-program .py
PythonHandler testingpython
PythonDebug On

   save the file as .htaccess.

   Now open up vi again and copy/paste the following lines:

   from mod_python import apache

   def handler(req):
        req.send_http_header()
        req.write("Hello World!")
        return apache.OK

   close and save as testingpython.py. Those are tabs not spaces. If you left align everything you will get this error:

   IndentationError: expected an indented block (testingpython.py, line 4)"

   Now restart Apache by typing: service httpd restart

Take your browser to www.mydomain.com/python/testingpython.py and you should see “Hello World!” If you can see this message then you have succesfully installed mod_python.
