You might have suffered from the problem of executing/running PHP or CGI programs in Ubuntu. For all your problems, here is the solution.
Steps to run php programs :--
- Open terminal and type sudo chmod -R 777 /var/www
- Now create a folder with the name php.
- Place your html files in /var/www folder and php files in /var/www/php folder.
Steps to run CGI programs :--
- Open terminal and type sudo chmod -R 777 /usr/lib/cgi-bin
- Now place your .cgi or .pl files in cgi-bin folder.
- Now open your browser and type http://localhost/cgi-bin/programname.cgi
Thank you :)
