title: Install and Configure varnish cache on Ubuntu server with VestaCP
body: <p>I would like to install and configure Varnish Cache to work properly on a VPS.
  The vps OS is Ubuntu 14.04 and I have installed and using VestaCP. Both Apache and nginx are installed on my vps. </p>
  
  <p>I find no problem installing the varnish cache on the vps, my problem is that I cannot configure it to work properly. All the documentation I find is for servers using either Apache or Nginx, but VestaCP installed both on my machine. I need to move both apache and nging to some other ports and move the varnish on port 80. 
  So, I need info on how to do that.</p>
  
  <p>Thank you all.</p>
