Learning Elasticsearch

Verifying Elasticsearch is running

In Chapter 1, Introduction to Elasticsearch, we described the RESTful API that Elasticsearch provides. By default, Elasticsearch runs on the 9200 HTTP port. Once Elasticsearch is running, you can verify Elasticsearch by executing the http://127.0.0.1:9200 URL in your favorite browser. You should see a JSON response similar to the following:

{   "name": "A_TmR2p",   "cluster_name": "elasticsearch",   "cluster_uuid": "Mp7tziykSjymFwBYozM4RA",   "version": {     "number": "5.1.2",     "build_hash": "c8c4c16",     "build_date": "2017-01-11T20:18:39.146Z",     "build_snapshot": false,     "lucene_version": "6.3.0"   },   "tagline": "You Know, for Search" }

You can see from the JSON response that the node name is A_TmR2p, cluster name is ...
