3.1 Installing mod_python

To install mod_python, we simply run:

yum install mod_python

 

3.2 Configuring Apache

Now we must configure Apache so that it can handle Python files. There are two ways of doing so. The first (and default) one is to use the Publisher Handler. It allows you to write pure Python scripts with the extension .py that will be interpreted by Apache. The second way is the PSP Handler. PSP stands for Python Server Pages. It allows you to embed Python code directly in HTML code, similar to PHP. PSP files have the extension .psp.

 

3.2.1 The Publisher Handler

To enable the Publisher Handler, we must edit the mod_python configuration which you can find in /etc/httpd/conf.d/python.conf. This file contains many examples - we make a backup of it and create that file again from scratch. I‘m using the default Fedora/CentOS document root /var/www/html here in the<Directory> directive - adjust this to your needs. The important lines are AddHandler mod_python .py and PythonHandler mod_python.publisher:

 
 

cp /etc/httpd/conf.d/python.conf /etc/httpd/conf.d/python.conf_orig
cat /dev/null > /etc/httpd/conf.d/python.conf
vi /etc/httpd/conf.d/python.conf

LoadModule python_module modules/mod_python.so

<Directory /var/www/html/>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride None
  Order allow,deny
  allow from all
  AddHandler mod_python .py
  PythonHandler mod_python.publisher
  PythonDebug On
</Directory>

Please note: if you use ISPConfig (from version 2.2.24 on) on the server, please leave out the <Directory ...>...</Directory> part in the above file since that would enable mod_python globally for the directory in question. In ISPConfig you can enable mod_python on a per-website basis instead which gives you more control whether a website can use mod_python or not.

Restart Apache afterwards:

/etc/init.d/httpd restart

Now we create a little Python test script (e.g. /var/www/html/test.py) with pure Python code in it...

vi /var/www/html/test.py

def index(req):
  return "Test successful";

... and call it in a browser (e.g. http://192.168.0.100/test.py). If all goes well, it should display Test successful in your browser.

 

3.2.2 The PSP Handler

To enable the PSP Handler, we must edit the mod_python configuration which you can find in /etc/httpd/conf.d/python.conf. This file contains many examples - we make a backup of it and create that file again from scratch. I‘m using the default Fedora/CentOS document root /var/www/html here in the <Directory>directive - adjust this to your needs. The important lines are AddHandler mod_python .py and PythonHandler mod_python.psp:

cp /etc/httpd/conf.d/python.conf /etc/httpd/conf.d/python.conf_orig
cat /dev/null > /etc/httpd/conf.d/python.conf
vi /etc/httpd/conf.d/python.conf

LoadModule python_module modules/mod_python.so

<Directory /var/www/html/>
  Options Indexes FollowSymLinks MultiViews
  AllowOverride None
  Order allow,deny
  allow from all
  AddHandler mod_python .psp
  PythonHandler mod_python.psp
  PythonDebug On
</Directory>

Please note: if you use ISPConfig (from version 2.2.24 on) on the server, please leave out the <Directory ...>...</Directory> part in the above file since that would enable mod_python globally for the directory in question. In ISPConfig you can enable mod_python on a per-website basis instead which gives you more control whether a website can use mod_python or not. Also note that ISPConfig does not support the PSP Handler - it uses the Publisher Handler.

Restart Apache afterwards:

/etc/init.d/httpd restart

Now we create a little PSP test script (e.g. /var/www/html/test.psp) with HTML and Python code in it...

vi /var/www/html/test.psp

<html>
<body>
<h1><% req.write("Hello!") %></h1>
</body>
</html>

... and call it in a browser (e.g. http://192.168.0.100/test.psp). If all goes well, it should display Hello! in your browser.
