How to write a simple CGI script using Python :
step 1: Install apache server in your linux machine:
for installation : sudo apt-get install --purge apache2 apache2-utils
if remove : sudo apt-get remove --purge apache2 apache2-utils
Now do your typical installation:
"sudo apt-get install apache2"
step 2:
First, you need an Apache server on your Linux/Mac OS/Windows box. If you are gonna use data base, you need a database server. There are tons of blogs addressing these issues. So I won't be gossipy here. Suppose everything we mention below happens on your server-even web browsing.
Second, configure cgi in Apache. There are many ways to run a Python program on a web/http interface. I think CGI is the easiest. Assume you are on your own server and using all default settings. On Ubuntu Linux 9.04, the default configuration file for your default website is
_________________________________________________________________________________
ScriptAlias /cgi-bin/ /var/www/cgi-bin/ specifies the path of cgi codes and the actual directory of your program. So when you type http://127.0.0.1/cgi-bin, the Apache will look into the directory
Now restart your apache. On Ubuntu Linux, by default installation and configuration, it is
sudo /etc/init.d/apache2 restart
Third, write up a Hello, World! program. Save it as hello.py and give it execution privilege for anyone.
Now open http://127.0.0.1/cgi-bin/hello.py in your web browser and you shall see a hello world in it.
If you have any error, e.g., 500 error, please check your Apache log file. It shall tell you something. You can find errors like what you have seen from a standard Python interpreter.

/etc/apache2/sites-available/default Open it, find the part for cgi directory, and make it like this_________________________________________________________________________________
ScriptAlias /cgi-bin/ /var/www/cgi-bin/
<Directory "/var/www/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
AddHandler cgi-script .py
# tell Apache to handle every file with .py suffix as a cgi program
AddHandler default-handler .html .htm
# tell Apache to handle HTML files in regular way
</Directory>

The line
ScriptAlias /cgi-bin/ /var/www/cgi-bin/ specifies the path of cgi codes and the actual directory of your program. So when you type http://127.0.0.1/cgi-bin, the Apache will look into the directory
/var/www/cgi-bin/ of your localhost.Now restart your apache. On Ubuntu Linux, by default installation and configuration, it is
sudo /etc/init.d/apache2 restart
Third, write up a Hello, World! program. Save it as hello.py and give it execution privilege for anyone.
1 2 3 4 5 6 | #!/usr/bin/env python print "Content-Type: text/html" print print """\ <html> <head><title>First Python HTTP Programming </title></head> <body> <h2>Hello World!</h2> </body> </html> """ |
If you have any error, e.g., 500 error, please check your Apache log file. It shall tell you something. You can find errors like what you have seen from a standard Python interpreter.
