Installing and configuring Elasticsearch

Elasticsearch is a search engine. In this book, you will use it as a NoSQL database. You will move data both to and from Elasticsearch to other locations. To download Elasticsearch, take the following steps:

2. Extract the files using the following command:

   tar xvzf elasticsearch.tar.gz

   bin/elasticsearch
