Elasticsearch is a search engine based on Lucene. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Elasticsearch is developed in [Java] and is released as open source under the terms of the Apache License.


Elasticsearch requires at least OpenJDK 7, setup [Java] first (if needed).

Install the elasticsearch package.


The main Elasticsearch configuration file is well-documented and located at /etc/elasticsearch/elasticsearch.yml.

  • By default Elasticsearch is public accessible, it may be preferred to allow only access on the host instead:
  • It is possible to use a custom port instead of the default {9200:
http.port: 9200
