Elasticsearch

Elasticsearch is the distributed, RESTful search and analytics engine at the heart of the Elastic Stack. You can use Elasticsearch to store, search, and manage data for:

Logs
Metrics
A search backend
Application monitoring
Endpoint security

... and more!

To learn more about Elasticsearch’s features and capabilities, see our product page.

Get started

The simplest way to set up Elasticsearch is to create a managed deployment with Elasticsearch Service on Elastic Cloud.

If you prefer to install and manage Elasticsearch yourself, you can download the latest version from elastic.co/downloads/elasticsearch.

For more installation options, see the Elasticsearch installation documentation.

Upgrade

To upgrade from an earlier version of Elasticsearch, see the Elasticsearch upgrade documentation.

Build from source

Elasticsearch uses Gradle for its build system.

To build a distribution for your local OS and print its output location upon completion, run:

./gradlew localDistro

To build a distribution for another platform, run the related command:

./gradlew :distribution:archives:linux-tar:assemble
./gradlew :distribution:archives:darwin-tar:assemble
./gradlew :distribution:archives:windows-zip:assemble

To build distributions for all supported platforms, run:

./gradlew assemble

Distributions are output to distributions/archives.

To run the test suite, see TESTING.
