title: nginx missing sites-available directory
body: <p>I installed Nginx on Centos 6 and I am trying to set up virtual hosts. The problem I am having is that I can't seem to find the <code>/etc/nginx/sites-available</code> directory.</p>
  
  <p>Is there something I need to do in order to create it? I know Nginx is up and running because I can browse to it.</p>
