  Why is the port number 8330 instead of 8080? Please check the settings

negative.code: then click the 'start' button at bottom right of the server list. Wait a
  moment and server-three should start now.
  
  Now we should also enable 'server-three' on the secondary Host Controller: From the top of menu
  list on left side of the page, we could see now we are managing the primary Host Controller
  currently. Click on the list, and click 'secondary', then choose
  'server-three', and we are in secondary Host Controller management page now.
  
  Then repeat the steps we've done on the primary host to start 'server-three' on
  secondary host.
  
  [TIP]
  
  server-three on primary and secondary host are two different hosts, their names
  can be different.
  
  After server-three on both primary and secondary hosts are started, we will add our
  cluster-demo.war for deployment. Click on the 'Manage Deployments' link
  at the bottom of left menu list.

  After enter 'Manage Deployments' page, click 'Add Content' at top right
