This section includes information on how to setup elasticsearch and get it running. If you haven’t already, download it, and then check the installation docs.

Elasticsearch can also be installed from our repositories using apt or yum. See Repositories.


After downloading the latest release and extracting it, elasticsearch can be started using:

$ bin/elasticsearch

Under *nix system, the command will start the process in the foreground. To run it in the background, add the -d switch to it:

$ bin/elasticsearch -d

Java (JVM) versionedit

Elasticsearch is built using Java, and requires at least Java 7 in order to run. Only Oracle’s Java and the OpenJDK are supported. The same JVM version should be used on all Elasticsearch nodes and clients.

We recommend installing the Java 8 update 20 or later, or Java 7 update 55 or later. Previous versions of Java 7 are known to have bugs that can cause index corruption and data loss. Elasticsearch will refuse to start if a known-bad version of Java is used.

The version of Java to use can be configured by setting the JAVA_HOME environment variable.
