[support] how to access Drupal base URL

[Ijlal EL HAZITI]

Good afternoon
I'm new to Drupal, I'm trying to install it but I'm having a little trouble
while accessing Drupal from my browser... I extracted Drupal in the
/var/www/html directory as said in the installation guid, then modified the
.htaccess file as mentioned in that link:
*http://www.exp-media.com/drupal7-htaccess-subfolder-tip
*
and uncommente*d*  the base_url variable, in the default.setting.php*:
*
*$base_url = 'http://localhost';  // NO trailing slash!*

but in vain, each time I try to access to http://localhost I get the
default apache page:

*the web server software is running but no content has been added, yet. *

What am I doing wrong?

Thank you. Cheers
