Web server support and configuration

Before you perform CGI programming, make sure that your Web server supports CGI and a CGI-configured handler.

Apache supports CGI configuration:

Set up the CGI directory:

scriptalias/cgi-bin//var/www/cgi-bin/

All HTTP server execution CGI programs are saved in a pre-configured directory. This directory is called the CGI directory and, by convention, it is named the/var/www/cgi-bin directory.

CGI files with the. cgi,python extension can also use the. py extension.

By default, the Linux server configuration runs in the Cgi-bin directory as/var/www.

If you want to specify other directories that run CGI scripts, you can modify the httpd.conf configuration file as follows:

<directory "/var/www/cgi-bin" >   allowoverride None   Options +execcgi   Order allow,deny   allow From all</directory>

Add the. py suffix in AddHandler so that we can access the Python script file at the end of the. PY:

AddHandler cgi-script. cgi. pl. py
