This documentation guide you through how to get started with Elasticsearch.

https://www.elastic.co/guide/en/elasticsearch/reference/current/deb.html

Use command line to run curl -X GET "localhost:9200/" to see if Elasticsearch is running. It should give the following if successful:

{
 “name” : “ip-172–31–28–88”,
 “cluster_name” : “my-application”,
 “cluster_uuid” : “dLfzIIfwSEWOnuu5i1I6OQ”,
 “version” : {
 “number” : “7.2.0”,
     “build_flavor” : “default”,
     “build_type” : “deb”,
     “build_hash” : “508c38a”,
     “build_date” : “2019–06–20T15:54:18.811730Z”,
     “build_snapshot” : false,
     “lucene_version” : “8.0.0”,
     “minimum_wire_compatibility_version” : “6.8.0”,
     “minimum_index_compatibility_version” : “6.0.0-beta1”
 },
 “tagline” : “You Know, for Search”
}

Alternatively, you can also check the status by sudo service elasticsearch status . If the service is down, run sudo service elasticsearch restart or sudo service elasticsearch stop to restart the service. Wait at least 30s to check the status again.

By default, all three services will automatically start when you launch the instance.
