title: Apache Server - Change port from 8080 to 80
body: <p>I have recently bought Amazon EC2 server. 
  Instead of installing it trough command line, I downloaded the latest zip file and deployed my application in WebApps folder.</p>
  
  <p>The problem is tomcat is listening all the requests on port 8080 instead of 80.
  I have tried changing the server.xml file in conf folder but no help!! 
  It is still listening to port 8080. </p>
  
  <p>How do I make it listen to port 80</p>
