The environment variable CONF_DIR was previously inconsistently used in our packaging to customize the location of Elasticsearch configuration files. The importance of this environment variable has increased starting in 6.0.0 as it's now used consistently to ensure Elasticsearch and all secondary scripts (e.g., elasticsearch-keystore) all use the same configuration. The name CONF_DIR is there for legacy reasons yet it's too generic. This commit renames CONF_DIR to ES_PATH_CONF. Relates #26197

=== 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",]
