=== 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.
|
|
|
|
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 requires Java 8 or later. Use the
|
|
http://www.oracle.com/technetwork/java/javase/downloads/index.html[official Oracle distribution]
|
|
or an open-source distribution such as http://openjdk.java.net[OpenJDK].
|

|
[[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 -a /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 -a /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
|
|
|
|
ifeval::["{release-state}"=="unreleased"]
|
|
|
|
Version {version} of Elasticsearch has not yet been released.

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}.deb
|
|
sha1sum elasticsearch-{version}.deb <1>
|
|
sudo dpkg -i elasticsearch-{version}.deb
|
|
--------------------------------------------
|
|
<1> Compare the SHA produced by `sha1sum` or `shasum` with the
|
|
https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-{version}.deb.sha1[published SHA].
|
|
|
|

include::init-systemd.asciidoc[]
|
|
|
|
[[deb-running-init]]
|
|
==== Running Elasticsearch with SysV `init`
|
|
|
|
Use the `update-rc.d` command to configure Elasticsearch to start automatically
|
|
when the system boots up:
|
|
|
|
[source,sh]
|
|
--------------------------------------------------
|
|
sudo update-rc.d elasticsearch defaults 95 10
|
|
--------------------------------------------------
|
|
|
|
Elasticsearch can be started and stopped using the `service` command:
|
|
|
|
[source,sh]
|
|
--------------------------------------------
|
|
sudo -i service elasticsearch start
|
|
sudo -i service elasticsearch stop
|
|
--------------------------------------------
|
|
|
|
If Elasticsearch fails to start for any reason, it will print the reason for
|
|
failure to STDOUT. Log files can be found in `/var/log/elasticsearch/`.

[[deb-configuring]]
|
|
==== Configuring Elasticsearch
|
|
|
|
Elasticsearch loads its configuration from the `/etc/elasticsearch/elasticsearch.yml`
|
|
file by default. The format of this config file is explained in
|
|
<<settings>>.
|
|
|
|
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",]
