 echo "deb https://artifacts.elastic.co/packages/6.x/apt stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-6.x.list

3. Install Elasticsearch

 sudo apt update && sudo apt install elasticsearch

4. Run sudo nano /etc/elasticsearch/elasticsearch.yml and Replace #network.host with network.host: localhost.
5. Start Elasticsearch with sudo systemctl start elasticsearch, for auto start every time sudo systemctl enable elasticsearch .
6. Run curl -X GET 'http://localhost:9200' for checking the connection with Elasticsearch.
