title: How does a server become part of a distributed system?
body: <p>The GemFire tutorial shows that a locator is started with<br>
  gfsh>start locator --name=locator1 --port=55221</p>
  
  <p>In some parts of the tutorial the command to start a server is shown as<br>
  gfsh>start server --name=server1 --J=-Dgemfire.jmx-manager=true --J=-Dgemfire.jmx-manager-start=true --J=-Dgemfire.http-port=8080</p>
  
  <p>In this case, how does the server know the locator on which it will get registered?</p>
