Installing Elasticsearch

To install Elasticsearch:

1. Unzip the Elasticsearch version that you downloaded earlier and edit the config/elasticsearch.yml file.

   vi config/elasticsearch.yml

2. Add the following lines to the file.

   transport.tcp.port: 9300
   http.cors.allow-origin: "*"
   http.cors.enabled: true

3. Specify a unique cluster name for your Elasticsearch instances to avoid conflicts with other Elasticsearch instances on the network. For example, specify ciohybris as shown in the following example.

   cluster.name: ciohybris

4. Start Elasticsearch.

   ./bin/elasticsearch

Elasticsearch is now running. You can access it at http://localhost:9200 in your web browser.
