Can't access my elasticsearch through public IP in EC2 instance

Question

I have deployed elasticsearch(7.3 version) service on my EC2 instance.

• After installing when I did curl localhost:9200it gave me correct response

Answer 1

So the solution was simply to modify the following settings in elasticsearch.yml:

network.host: 0.0.0.0
discovery.type: single-node

Note: The second setting is only necessary if you have a single node.
