The default apache has been loaded and I enabled to load it using http://localhost/.
Do you mean an 'apache2-default' page containing 'it works!'?

It should like http://localhost. Have you restarted Apache after modifying ports.conf file?
Under the /etc/apache2/sites-available is has soft link to /etc/koha/koha-httpd.conf as stated under INSTALL.debian. Both OPAC and Intranet has the following statements:
You may have to understand whether there is something wrong here. Default installation defines Koha web site as a virtual host. See Apache documentation: http://httpd.apache.org/docs/2.2/en/vhosts/name-based.html Check apache log files: /var/log/apache2/ You can try to disable default Apache web site: a2dissite default apache2ctl restart Revert on default web site this way: a2ensite default apache2ctl restart If you modify any apache config file, restart Apache: apache2ctl restart
