• To install Perl on windows, first download "ActivePerl" from www.activestate.com.
• Goto to the ActivePerl page, Click on Download button.
• Choose the version say ActivePerl 5.8.8.820, click on the MSI link under the Windows(x86).
• Double click on the installer and follow the instruction, click next to finish the installation.

• Open the httpd configuration file from C:\Program Files\Apache Group\Apache\conf\httpd.conf.
• Depending on the system one has to change the path in this file, say like c:\programfiles\apache\conf\
• Search for "AddModule mod_cgi.c" and remove the # before that line.
• Search for "AddType application/x-tar .tgz" and in the next line add "Addtype cgi-script .cgi .pl".
• Restart Apache if it is already running. And now apache is ready to parse and execute .cgi and .pl scripts.

Now you are ready to use Perl with Apache server.

• By default Perl will be installed in Linux.
• To know the location where perl is installed in your linux machine, execute the command "whereis perl", it gives the path /usr/bin.
• To execute a file from command prompt, use perl filename.pl inside root.
• If the Perl is not installed in the current path then use the command perl /usr/bin/perl filename.pl.

• To check all the working directories, type "ls" from root.
• Check if the module mod-perl.so is present in path etc/httpd/modules.
• Check for conf.d is present inside etc/httpd/conf.d.
• Goto cd/conf.d. then type in vim perl.conf
• Check for the module Loadmodule Perlmodule modules/mod_perl.so, uncomment if it is commented.
• If AddHandler cgi-script .cgi .pl is commented, uncomment it.
• In the directory /var/www/html user has to add "ExecCGI" to the following lines.

        Options Indexes FollowSymLinks ExecCGI
        SetHandler cgi-script
    

• Just execute your Perl file from the browser like localhost/filename.pl.

Note:This tutorial assumes that your server has Perl installed in it.
