Python learnings #2 - apache mod-python

This tells you how to install mod_python so that you can code for the web in python, in other words, stay in one language for the backend and frontend.

 

$ sudo apt-get update

$ sudo apt-get install libapache2-mod-python libapache2-mod-python-doc

Configure mod_python

You need to create directory to host your python scripts assuming that your root html directory is /var/www. Type the following command:

$ sudo mkdir /var/www/py
$ sudo chown yourname:www-data /var/www/py

Now, open /etc/apache2/sites-available/default and add following code:

        AddHandler mod_python .py
        PythonHandler hello
        PythonDebug On

Note that PythonHandler is hello which is hello.py. Save and close the file. Restart Apache2 server.

/etc/init.d/apache2 restart

$ vi /var/www/py/hello.py
The following simple mod_python program serves as a good test:
import sys
sys.path.append('/var/www/html')
from mod_python import apache
 
def handler(req):
        req.log_error('handler')
        req.content_type = 'text/html'
        req.send_http_header()
        req.write('Testing mod_python')
        req.write('Hello World!')
        req.write('')
        return apache.OK
Save and close the file. Now fire a webbrowser and type the url:
http://localhost/py/hello.py
