[CentOS] Apache 2.2 itk - 404 not found

Hi all, Freshly installed apache 2.2 with httpd-itk (from epel). When I 
try to access apache's document root from a browser on local network, it 
always serve me the Apache welcome page, even if I have a index.html and 
a phpinfo.php file in the /var/www/html folder. If point the browser 
specifically to http://server/index.html, I get a '404 Not found error'. 
I'm running CentOS 6.6 x86_64. I've been googling this for a couple of 
days and found nothing. Here's a few output that might be useful:

    [root at srv01 ~]# rpm -qa |grep httpd

    httpd-tools-2.2.15-39.el6.centos.x86_64
