title: How to set up ES cluster?
body: <p>Assuming I have 5 machines I want to run an elasticsearch cluster on, and they are all connected to a shared drive. I put a single copy of elasticsearch onto that shared drive so all three can see it. Do I just start the elasticsearch on that shared drive on eall of my machines and the clustering would automatically work its magic? Or would I have to configure specific settings to get the elasticsearch to realize that its running on 5 machines? If so, what are the relevant settings? Should I worry about configuring for replicas or is it handled automatically?</p>
