title: Change Listen Port on httpd config for Varnish Configuration
body: <p>I installed Varnish Cache my CentOS server.I try the do configuration correctly but as I read many document say to me change apache port <code>Listen 80</code> to <code>Listen 8080</code>. But I couldn't find any Listen 80 line on my server <code>/etc/httpd/conf/httpd.conf</code> but i found <code>0.0.0.0:80</code> line. Is it same thing ? If those are same thinhgs, when i change my sites not working. </p>
  
  <p>I know that I make huge logical mistake but i can't understand.</p>
  
  <p>Thanks</p>
