Setup ElasticSearch

This section describes how to setup ElasticSearch to be used in GeoNetwork to store the search/content statistics. Note that Geonetwork must have been built with the es profile for ElasticSearch to be used. See https://github.com/geonetwork/core-geonetwork/tree/master/software_development for details.

Installation

ElasticSearch can be installed manually, or for some operating systems packages are available.

Note

If installed manually, ElasticSearch must be configured as a service to ensure it starts automatically when the server is started. This is beyond the scope of this guide.

To install manually:

• Download ElasticSearch from http://www.elastic.co/downloads/past-releases/. For Geonetwork 3.8.x version 7.2.x is recommended.

• Unzip the file and copy it, for example, to /opt/elasticsearch

• Execute Elastic Search:

  $ cd /opt/elasticsearch/bin
  $ ./elasticsearch &
  

• Verify in a browser that ElasticSearch is running: http://localhost:9200/
