Python CGI in Apache httpd server

Pre-requisite: Working Apache Server.

 

In httpd-vhosts.conf:

Add below content inside <VirtualHost …>

ScriptAlias /cgi-bin/ "/cgi-bin/" 
<directory "<httpd-installed-path="">/cgi-bin/">
         Options Indexes FollowSymLinks ExecCGI
         AddHandler cgi-script .cgi .py
         AllowOverride None
         Require all granted

Now create a new file ‘test.py’ in /cgi-bin/  with content:

#!/usr/bin/env python

import cgi
cgi.test()

Make sure the below line is not commented in httpd.conf

LoadModule cgi_module modules/mod_cgi.so

Start/Restart apache server.

You can verify the loaded cgi module using the command:

sudo [path/]apachectl -M | grep cgi

Try below url in web-browser:

http://<ip/hostname>:/cgi-bin/test.py

eg:
http://localhost:1025/cgi-bin/test.py
http://localhost:80/cgi-bin/test.py

You will get a page with details on current working directory, command line arguments, etc..

Apache httpd: APR not found; error while installation

During Apache httpd installation if you get below error, that means Apache Portable Run-time environment was not found or not installed.

checking for APR... no
configure: error: APR not found.  Please read the documentation.

and/or

checking for APR-util... no
configure: error: APR-util not found. Please read the documentation.

So install APR and APR-util and give httpd those paths. Httpd will be happy to run for you after that… 🙂

Go further if you want to know how to install APR.

You can download APR and APR-util from here.

Then extract those to separate folders.

First change to the extract APR directory and install it. (Tip: cd command to change directory)

sudo ./configure --prefix=<apr-path>

sudo make

sudo make install

So you have a working APR. Next is APR-util.

Change to the extract APR-Util directory and install it. (Tip: cd command to change directory)

sudo ./configure --prefix=<apr-util-path> --with-prefix=<apr-path>

sudo make

sudo make instal

Install zlib packages with the command (optional; you can turn this off at your will):

yum install zlib zlib-devel

Apart from APR and APR-Util, you may need to install pcre too. So download it from here first.

Change to the directory and use the below commands to install.

sudo ./configure --prefix=<pcre-path>

sudo make

sudo make install

Now lets make httpd understand that we have a working pcre, APR and APR-util.

./configure --enable-file-cache --enable-cache --enable-disk-cache --enable-mem-cache --enable-deflate --enable-expires --enable-headers --enable-usertrack --enable-cgi --enable-vhost-alias --enable-rewrite --enable-so --prefix=<httpd-path> --with-apr=<apr-path> --with-apr-util=<apr-util-path> --with-pcre=<pcre-path>

# Rest is history make make install
