=== Install Elasticsearch with MSI Windows Installer

Elasticsearch can be installed on Windows using the `.msi` package.  This can
install Elasticsearch as a Windows service or allow it to be run manually using
the included `elasticsearch.exe` executable.

TIP: Elasticsearch has historically been installed on Windows using the <<zip-windows, .zip>> archive.
You can continue using the `.zip` approach if you prefer.

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].

[[download-msi]]
==== Download the `.msi` package

ifeval::["{release-state}"=="unreleased"]

Version {version} of Elasticsearch has not yet been released.

endif::[]

ifeval::["{release-state}"!="unreleased"]

Download the `.msi` package for Elasticsearch v{version} from https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-{version}.msi

endif::[]

[[install-msi-gui]]
==== Install using the graphical user interface (GUI)

Double-click the downloaded `.msi` package to launch a GUI wizard that will guide you through the 
installation process. You can view help on any step by clicking the `?` button, which reveals an
aside panel with additional information for each input:

[[msi-installer-help]]
image::images/msi_installer/msi_installer_help.png[]

Within the first screen, select the directory for the installation. In addition, select directories for where
data, logs and configuration will reside or <<msi-command-line-options,roll with the default locations>>:

[[msi-installer-locations]]
image::images/msi_installer/msi_installer_locations.png[]

Then select whether to install as a service or start Elasticsearch manually as needed. When
installing as a service, you can also decide which account to run the service under as well
as whether the service should be started after installation and when Windows is started or 
restarted:

[[msi-installer-service]]
image::images/msi_installer/msi_installer_service.png[]

IMPORTANT: When selecting an account to run the service with, be sure that the chosen account
has sufficient privileges to access the installation and other deployment directories chosen.

Common configuration settings are exposed within the Configuration section, allowing the cluster
name, node name and roles to be set, in addition to memory and network settings:

[[msi-installer-configuration]]
image::images/msi_installer/msi_installer_configuration.png[]

Finally, the installer provides a list of common plugins that can be downloaded and installed as
part of the installation:

[[msi-installer-selected-plugins]]
image::images/msi_installer/msi_installer_selected_plugins.png[]

By default, the {xpack-ref}/index.html[X-Pack] plugin will be selected to be installed, and if 
installing with the <<ingest, ingest>> node role, the {plugins}/ingest-attachment.html[Ingest Attachment Processor] and {plugins}/ingest-geoip.html[Ingest GeoIP Processor] plugins will also be selected for installation.

NOTE: X-Pack includes a trial license for 30 days. After that, you can obtain one of the https://www.elastic.co/subscriptions[available subscriptions] or {xpack-ref}/security-settings.html[disable Security]. The Basic license is free and includes the https://www.elastic.co/products/x-pack/monitoring[Monitoring] extension.

After clicking the install button, Elasticsearch will be installed:

[[install-msi-command-line]]
==== Install using the command line

The `.msi` can also install Elasticsearch using the command line. The simplest installation
using the same defaults as the GUI is achieved by first navigating to the download directory,
then running:

["source","sh",subs="attributes,callouts"]
--------------------------------------------
msiexec.exe /i elasticsearch-{version}.msi /qn
--------------------------------------------

By default, msiexec does not wait for the installation process to complete, since it runs in the 
Windows subsystem. To wait on the process to finish and ensure that `%ERRORLEVEL%` is set
accordingly, it is recommended to use `start /wait` to create a process and wait for it to exit

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /i elasticsearch-{version}.msi /qn
--------------------------------------------

As with any MSI installation package, a log file for the installation process can be found 
within the `%TEMP%` directory, with a randomly generated name adhering to the format 
`MSI*.LOG`. The path to a log file can be supplied using the `/l` command line argument

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /i elasticsearch-{version}.msi /qn /l install.log
--------------------------------------------

Supported Windows Installer command line arguments can be viewed using

["source","sh",subs="attributes,callouts"]
--------------------------------------------
msiexec.exe /help
--------------------------------------------

or by consulting the https://msdn.microsoft.com/en-us/library/windows/desktop/aa367988(v=vs.85).aspx[Windows Installer SDK Command-Line Options].

the installation command. For example, to use a different installation directory to the default one:

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /i elasticsearch-{version}.msi /qn INSTALLDIR="C:\Custom Install Directory"
--------------------------------------------

Consult the https://msdn.microsoft.com/en-us/library/windows/desktop/aa367988(v=vs.85).aspx[Windows Installer SDK Command-Line Options]
for additional rules related to values containing quotation marks. 

[[msi-installer-command-line-running]]
==== Running Elasticsearch from the command line

Once installed, Elasticsearch can be started from the command line, if not installed as a service
and configured to start when installation completes, as follows:

["source","sh",subs="attributes,callouts"]
--------------------------------------------
.\bin\elasticsearch.exe
--------------------------------------------

By default, Elasticsearch runs in the foreground, prints its logs to `STDOUT` in addition
to the `<cluster name>.log` file within `LOGSDIRECTORY`, and can be stopped by pressing `Ctrl-C`.

[[msi-installer-command-line-configuration]]
==== Configuring Elasticsearch on the command line

Elasticsearch loads its configuration from the `%ES_HOME%\config\elasticsearch.yml`
file by default.  The format of this config file is explained in
<<settings>>.

Any settings that can be specified in the config file can also be specified on
the command line, using the `-E` syntax as follows:

["source","sh",subs="attributes,callouts"]
--------------------------------------------
.\bin\elasticsearch.exe -E cluster.name=my_cluster -E node.name=node_1
--------------------------------------------

NOTE: Values that contain spaces must be surrounded with quotes.  For instance `-E path.logs="C:\My Logs\logs"`.

TIP: Typically, any cluster-wide settings (like `cluster.name`) should be
added to the `elasticsearch.yml` config file, while any node-specific settings
such as `node.name` could be specified on the command line.

include::check-running.asciidoc[]

[[msi-installer-windows-service]]
==== Installing Elasticsearch as a Service on Windows

Elasticsearch can be installed as a service to run in the background or start
automatically at boot time without any user interaction. This can be achieved upon installation
using the following command line options
 
* `INSTALLASSERVICE=true` 
* `STARTAFTERINSTALL=true` 
* `STARTWHENWINDOWSSTARTS=true` 

Once installed, Elasticsearch will appear within the Services control panel:

[[msi-installer-installed-service]]
image::images/msi_installer/msi_installer_installed_service.png[]

and can be stopped and restarted from within the control panel, or from the command line using:

with Command Prompt:

[source,sh]
--------------------------------------------
sc.exe stop Elasticsearch
sc.exe start Elasticsearch
--------------------------------------------

with PowerShell:

[source,powershell]
--------------------------------------------
Get-Service Elasticsearch | Stop-Service | Start-Service
--------------------------------------------

Changes can be made to jvm.options and elasticsearch.yml configuration files to configure the 
service after installation. Most changes (like JVM settings) will require a restart of the 
service in order to take affect.

[[upgrade-msi-gui]]
==== Upgrade using the graphical user interface (GUI)

The `.msi` package supports upgrading an installed version of Elasticsearch to a newer 
version of Elasticsearch. The upgrade process handles upgrading all installed plugins as
well as retaining both your data and configuration.

Downloading and clicking on a newer version of the `.msi` package will launch the GUI wizard. 
The first step will list the read only properties from the previous installation:

[[msi-installer-upgrade-notice]]
image::images/msi_installer/msi_installer_upgrade_notice.png[]

The following configuration step allows certain configuration options to be changed:

[[msi-installer-upgrade-configuration]]
image::images/msi_installer/msi_installer_upgrade_configuration.png[]

Finally, the plugins step allows currently installed plugins to be upgraded or removed, and 
for plugins not currently installed, to be downloaded and installed:

[[msi-installer-upgrade-plugins]]
image::images/msi_installer/msi_installer_upgrade_plugins.png[]

[[upgrade-msi-command-line]]
==== Upgrade using the command line

The `.msi` can also upgrade Elasticsearch using the command line. The simplest upgrade
using the same defaults as the currently installed version is achieved by first 
navigating to the download directory, then running:

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /i elasticsearch-{version}.msi /qn
--------------------------------------------

Similar to the install process, a path to a log file for the upgrade process can
be passed using the `/l` command line argument

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /i elasticsearch-{version}.msi /qn /l upgrade.log
--------------------------------------------

[[uninstall-msi-gui]]
==== Uninstall using Add/Remove Programs

The `.msi` package handles uninstallation of all directories and files added as part of installation.

WARNING: Uninstallation will remove all directories and their contents created as part of 
installation, including data within the data directory. If you wish to retain your data upon
uninstallation, it is recommended that you make a copy of the data directory before uninstallation.

MSI installer packages do not provide a GUI for uninstallation. An installed program can be uninstalled
by pressing the Windows key and typing `add or remove programs` to open the system settings.

Once opened, find the Elasticsearch installation within the list of installed applications, click
and choose `Uninstall`:

[[msi-installer-uninstall]]
image::images/msi_installer/msi_installer_uninstall.png[]

This will launch the uninstallation process.

[[uninstall-msi-command-line]]
==== Uninstall using the command line

Uninstallation can also be performed from the command line by navigating to the directory
containing the `.msi` package and running:

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /x elasticsearch-{version}.msi /qn
--------------------------------------------

Similar to the install process, a path to a log file for the uninstallation process can
be passed using the `/l` command line argument

["source","sh",subs="attributes,callouts"]
--------------------------------------------
start /wait msiexec.exe /x elasticsearch-{version}.msi /qn /l uninstall.log
--------------------------------------------
