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

$ bin/elasticsearch -d

*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 or getopt long style configuration parameters directly to the script. When set, all override anything set using either JAVA_OPTS or ES_JAVA_OPTS. For example:

$ bin/elasticsearch -Xmx2g -Xms2g -Des.index.store.type=memory --node.name=my-node

Java version

edit

Elasticsearch is built using Java, and requires at least Java 7 in order to run [1.2.0] Added in 1.2.0. Was at least Java 6 before . Only Oracle’s Java and the OpenJDK are supported.

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.

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