This commit introduces a dedicated envirnoment variable ES_JAVA_HOME to determine the JDK used to start (if not using the bundled JDK). This environment variable will replace JAVA_HOME. The reason that we are making this change is because JAVA_HOME is a common environment variable and sometimes users have it set in their environment from other JDK applications that they have installed on their system. In this case, they would accidentally end up not using the bundled JDK despite their intentions. By using a dedicated environment variable specific to Elasticsearch, we avoid this potential for conflict. With this commit, we introduce the new environment variable, and deprecate the use of JAVA_HOME. We will remove support for JAVA_HOME in a future commit.

=== Install Elasticsearch with Debian Package
|
|
|
|
The Debian package for Elasticsearch can be <<install-deb,downloaded from our website>>
|
|
or from our <<deb-repo,APT repository>>. It can be used to install
|
|
Elasticsearch on any Debian-based system such as Debian and Ubuntu.
|
|
|
|
include::license.asciidoc[]
|
|
|
|
The latest stable version of Elasticsearch can be found on the
|
|
link:/downloads/elasticsearch[Download Elasticsearch] page. Other versions can
|
|
be found on the link:/downloads/past-releases[Past Releases page].
|
|
|
|
NOTE: Elasticsearch includes a bundled version of https://openjdk.java.net[OpenJDK]
|
|
from the JDK maintainers (GPLv2+CE). To use your own version of Java,
|
|
see the <<jvm-version, JVM version requirements>>
|
|
|
|
[[deb-key]]
|
|
==== Import the Elasticsearch PGP Key
|
|
|
|
include::key.asciidoc[]
|
|
|
|
[source,sh]
|
|
-------------------------
|
|
wget -qO - https://artifacts.elastic.co/GPG-KEY-elasticsearch | sudo apt-key add -
|
|
-------------------------
|
|
|
|
[[deb-repo]]
|
|
==== Installing from the APT repository
|
|
|
|
ifeval::["{release-state}"=="unreleased"]
|
|
|
|
Version {version} of Elasticsearch has not yet been released.
|
|
|
|
endif::[]
|
|

ifeval::["{release-state}"!="unreleased"]
|
|
|
|
You may need to install the `apt-transport-https` package on Debian before proceeding:
|
|
|
|
[source,sh]
|
|
--------------------------------------------------
|
|
sudo apt-get install apt-transport-https
|
|
--------------------------------------------------
|
|
|
|
Save the repository definition to +/etc/apt/sources.list.d/elastic-{major-version}.list+:
|
|
|
|
ifeval::["{release-state}"=="released"]
|
|
|
|
["source","sh",subs="attributes,callouts"]
|
|
--------------------------------------------------
|
|
echo "deb https://artifacts.elastic.co/packages/{major-version}/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-{major-version}.list
|
|
--------------------------------------------------
|
|
|
|
endif::[]
|
|
|
|
ifeval::["{release-state}"=="prerelease"]
|
|
|
|
["source","sh",subs="attributes,callouts"]
|
|
--------------------------------------------------
|
|
echo "deb https://artifacts.elastic.co/packages/{major-version}-prerelease/apt stable main" | sudo tee /etc/apt/sources.list.d/elastic-{major-version}.list
|
|
--------------------------------------------------
|
|
|
|
endif::[]
|
|
|
|
|
|
[NOTE]
|
|
==================================================
|
|
|
|
These instructions do not use `add-apt-repository` for several reasons:
|
|
|
|
. `add-apt-repository` adds entries to the system `/etc/apt/sources.list` file
|
|
rather than a clean per-repository file in `/etc/apt/sources.list.d`
|
|
. `add-apt-repository` is not part of the default install on many distributions
|
|
and requires a number of non-default dependencies.
|
|
. Older versions of `add-apt-repository` always add a `deb-src` entry which
|
|
will cause errors because we do not provide a source package. If you have added
|
|
the `deb-src` entry, you will see an error like the following until you delete
|
|
the `deb-src` line:
|
|
|
|
Unable to find expected entry 'main/source/Sources' in Release file
|
|
(Wrong sources.list entry or malformed file)
|
|
|
|
==================================================
|
|
|
|
You can install the Elasticsearch Debian package with:
|
|
|
|
[source,sh]
|
|
--------------------------------------------------
|
|
sudo apt-get update && sudo apt-get install elasticsearch
|
|
--------------------------------------------------
|
|
|
|
[WARNING]
|
|
==================================================
|
|
If two entries exist for the same Elasticsearch repository, you will see an error like this during `apt-get update`:
|
|
|
|
["literal",subs="attributes,callouts"]
|
|
|
|
Duplicate sources.list entry https://artifacts.elastic.co/packages/{major-version}/apt/ ...`
|
|
|
|
Examine +/etc/apt/sources.list.d/elasticsearch-{major-version}.list+ for the duplicate entry or locate the duplicate entry amongst the files in `/etc/apt/sources.list.d/` and the `/etc/apt/sources.list` file.
|
|
==================================================

==== Download and install the Debian package manually

The Debian package for Elasticsearch v{version} can be downloaded from the website and installed as follows:
|
|
|
|
["source","sh",subs="attributes"]
|
|
--------------------------------------------
|
|
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-{version}-amd64.deb
|
|
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-{version}-amd64.deb.sha512
|
|
shasum -a 512 -c elasticsearch-{version}-amd64.deb.sha512 <1>
|
|
sudo dpkg -i elasticsearch-{version}-amd64.deb
|
|
--------------------------------------------
|
|
<1> Compares the SHA of the downloaded Debian package and the published checksum, which should output
|
|
`elasticsearch-{version}-amd64.deb: OK`.

==== Configuring Elasticsearch
|

|
|
include::etc-elasticsearch.asciidoc[]
|
|
|
|
The Debian package also has a system configuration file (`/etc/default/elasticsearch`),
|
|
which allows you to set the following parameters:
|
|
|
|
include::sysconfig-file.asciidoc[]
|
|
|
|
NOTE: Distributions that use `systemd` require that system resource limits be
|
|
configured via `systemd` rather than via the `/etc/sysconfig/elasticsearch`
|
|
file. See <<systemd>> for more information.
|
|
|
|
[[deb-layout]]
|
|
==== Directory layout of Debian package
|
|
|
|
The Debian package places config files, logs, and the data directory in the appropriate
|
|
locations for a Debian-based system:
|
|
|
|
|
|
[cols="<h,<,<m,<m",options="header",]
