Create Multiple Nodes

Hi I was using the Elasticsearch Definitive Guide walkthrough, and it asked me to create a second node the same way I created the first one. However, when I went to the [instructions on creating] ( another node I couldn't figure it out. I tried running ./bin/elasticsearch -d again to create another node but that didn't work for me. Can someone please clarify how to create another node?

What was the output when you ran the command?

When I ran the command in the terminal there was no output
