I installed the Elastic Search by downloading the .deb package from this link.
After installing I tried to browse to http://localhost:9200/ where I'm getting connection refused error, so I checked the status of elastic search service by running the following command sudo service elasticsearch status and I'm getting the below logs :
● elasticsearch.service - Elasticsearch

Can some one tell me how to start the service?
