Installation of Elasticsearch



Step by Step instructions on how to install elasticsearch

Elasticsearch is an open-source, RESTful, distributed search and analytics engine built on Apache Lucene.

Every feature of Elasticsearch is exposed as a REST API:

  1. Index API: Used to document the index.
  2. Get API: Used to retrieve the document.
  3. Search API: Used to submit your query and get a result.
  4. Put Mapping API: Used to override default choices and define the mapping.

Elasticsearch requires at least Java 8. It is recommended that you use the Oracle JDK version 1.8.0_131.

from the command line, type:

java -version
echo $JAVA_HOME

cd elasticsearch-6.4.2/bin
./elasticsearch
