=== 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].

[[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:
