Elasticsearch

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

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

Run this command to see if Elasticsearch is running.

curl -X GET "localhost:9200/"

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 typing

sudo service elasticsearch status

If the service is down, restart or stop elasticsearch service.

sudo service elasticsearch restart

or

sudo service elasticsearch stop

Wait at least 30s to check the status again.

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