How do I create multiple nodes on the same computer

[dadoonet (David Pilato)]

You can read this:

Create multiple nodes elasticsearch 5.4

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.
