  <p>I want to configure 2 apache http servers and 3 tomcat server on window7 machine.</p>
  
  <p>Currently I have done configuration with 1 http server and 2 or more tomcat server, but unable to do configuration of 2 http servers on same windows machine.Whenever I start second time of http server(2nd instance) then is says like this:</p>
  
  <pre><code>httpd: Could not reliably determine the server's fully qualified domain name, 
  using 172.17.124.181 for ServerName (OS 10048)Only one usage of each socket
  address (protocol/network address/port) is normally permitted.:
  make_sock: could not bind to address 0.0.0.0:80 no listening sockets available,
  shutting down Unable to open logs
  </code></pre>
  
  <p>Please let me know how I can I run two instances of HTTP servers on same windows machine.
  Help is appreciated.
  Thanks in advance.</p>
