Setup

edit

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.

Installation

edit

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 background. To run it in the foreground, add the -f switch to it:

$ bin/elasticsearch -f

ElasticSearch is built using Java, and requires at least Java 6 in order to run. The version of Java that will be used can be set by setting the JAVA_HOME environment variable.

*NIX

There are added features when using the elasticsearch shell script. The first, which was explained earlier, is the ability to easily run the process either in the foreground or the background.

Another feature is the ability to pass -X and -D directly to the script. When set, both override anything set using either JAVA_OPTS or ES_JAVA_OPTS. For example:

$ bin/elasticsearch -f -Xmx2g -Xms2g -Des.index.store.type=memory
