=== Install Elasticsearch with RPM
|
|
|
|
The RPM for Elasticsearch can be <<install-rpm,downloaded from our website>>
|
|
or from our <<rpm-repo,RPM repository>>. It can be used to install
|
|
Elasticsearch on any RPM-based system such as OpenSuSE, SLES, Centos, Red Hat,
|
|
and Oracle Enterprise.
|
|
|
|
NOTE: RPM install is not supported on distributions with old versions of RPM,
|
|
such as SLES 11 and CentOS 5. Please see <<zip-targz>> instead.
|
|
|
|
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].
|
|
|
|
[[rpm-key]]
|
|
==== Import the Elasticsearch PGP Key
|
|
|
|
include::key.asciidoc[]
|
|
|
|
[source,sh]
|
|
-------------------------
|
|
rpm --import https://packages.elastic.co/GPG-KEY-elasticsearch
|
|
-------------------------
|
|
|
|
[[rpm-repo]]
|
|
==== Installing from the RPM repository
|
|
|
|
Create a file called `elasticsearch.repo` in the `/etc/yum.repos.d/` directory
|
|
for RedHat based distributions, or in the `/etc/zypp/repos.d/` directory for
|
|
OpenSuSE based distributions, containing:
|
|
|
|
["source","sh",subs="attributes,callouts"]
|
|
--------------------------------------------------
|
|
[elasticsearch-{major-version}]
|
|
name=Elasticsearch repository for {major-version} packages
|
|
baseurl=https://packages.elastic.co/elasticsearch/{major-version}/centos
|
|
gpgcheck=1
|
|
gpgkey=https://packages.elastic.co/GPG-KEY-elasticsearch
|
|
enabled=1
|
|
autorefresh=1
|
|
type=rpm-md
|
|
--------------------------------------------------
|
|
|
|
And your repository is ready for use. You can now install Elasticsearch with one of the following commands:
|
|
|
|
[source,sh]
|
|
--------------------------------------------------
|
|
sudo yum install elasticsearch <1>
|
|
sudo dnf install elasticsearch <2>
|
|
sudo zypper install elasticsearch <3>
|
|
--------------------------------------------------
|
|
<1> Use `yum` on CentOS and older Red Hat based distributions.
|
|
<2> Use `dnf` on Fedora and other newer Red Hat distributions.
|
|
<3> Use `zypper` on OpenSUSE based distributions
|
|
|
|
[[install-rpm]]
|
|
==== Download and install the RPM manually
|
|
|
|
The RPM for Elastisearch v{version} can be downloaded from the website and installed as follows:
|
|
|
|
["source","sh",subs="attributes"]
|
|
--------------------------------------------
|
|
wget https://download.elastic.co/elasticsearch/release/org/elasticsearch/distribution/rpm/elasticsearch/{version}/elasticsearch-{version}.rpm
|
|
sha1sum elasticsearch-{version}.rpm <1>
|
|
sudo rpm --install elasticsearch-{version}.rpm
|
|
--------------------------------------------
|
|
<1> Compare the SHA produced by `sha1sum` or `shasum` with the
|
|
https://download.elastics.co/elasticsearch/release/org/elasticsearch/distribution/rpm/elasticsearch/{version}/elasticsearch-{version}.rpm.sha1[published SHA].
|
|

include::init-systemd.asciidoc[]
|
|
|
|
[[rpm-running-init]]
|
|
==== Running Elasticsearch with SysV `init`
|
|
|
|
Use the `chkconfig` command to configure Elasticsearch to start automatically
|
|
when the system boots up:
|
|
|
|
[source,sh]
|
|
--------------------------------------------------
|
|
sudo chkconfig --add elasticsearch
|
|
--------------------------------------------------
|
|
|
|
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/`.

[[rpm-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 RPM also has a system configuration file (`/etc/sysconfig/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.
|
|
|
|
[[rpm-layout]]
|
|
==== Directory layout of RPM
|
|
|
|
The RPM places config files, logs, and the data directory in the appropriate
|
|
locations for an RPM-based system:
|
|
|
|
|
|
[cols="<h,<,<m,<m",options="header",]
