You can't create a new node using `elasticsearch.yml`.  
You can start a new node though. Ideally on another machine unless you have more than 64gb of RAM on your machine.

For dev purpose, you can easily run the `bin/elasticsearch` multiple times. But you need to change one of those two options:

- [https://www.elastic.co/guide/en/elasticsearch/reference/6.4/modules-node.html#max-local-storage-nodes](https://www.elastic.co/guide/en/elasticsearch/reference/6.4/modules-node.html#max-local-storage-nodes)

Thanks @dadoonet

via #discovery.zen.ping.unicast.hosts: ["host1", "host2"] this one we can configure another node ?can you explain what is the use of this one ?

Let say you start 2 nodes, one on [node1.company.com](http://node1.company.com) the other one on [node2.company.com](http://node2.company.com).

You'll need to make aware node1 how to reach node2 and the other way.

So you will actually put in both `elasticsearch.yml`:

```auto
discovery.zen.ping.unicast.hosts: ["node1.company.com", "node2.company.com"]

```
