I currently have one node running on my machine, but I'm curious how I can get 3 nodes running. Does each node require a separate yml config file with the same [cluster.name](http://cluster.name) or is there a way to specify within the one elasticsearch.yml file? I'm sure there's documentation out there for this, but I haven't been able to find anything specific to this topic.

My ES version:  
`Version: 5.1.1, Build: 5395e21/2016-12-06T12:36:15.409Z, JVM: 1.8.0_77`

You can read this:

> [@Create multiple nodes elasticsearch 5.4](https://discuss.elastic.co/t/create-multiple-nodes-elasticsearch-5-4/86101/6):
>
> If you want to start multiple nodes on the same machine (for tests purposes) just run: bin/elasticsearch -Epath.data=data1 -Epath.logs=log1 bin/elasticsearch -Epath.data=data2 -Epath.logs=log2 bin/elasticsearch -Epath.data=data3 -Epath.logs=log3 Without changing anything in the default elasticsearch.yml and you should be done.

Thank you @dadoonet - that's what I needed. It looks like I'm just telling elasticsearch to give the data node (hopefully my terminology is correct here) and log file location different names. I'm assuming I can do the same right within my default yml config file on my dev machine and that's all I really need?

Thank you!

I see this thread on Stack Overflow which I think will give me some insight into doing this. [https://stackoverflow.com/questions/35717790/how-to-add-a-new-node-to-my-elasticsearch-cluster](https://stackoverflow.com/questions/35717790/how-to-add-a-new-node-to-my-elasticsearch-cluster)
