=== Plugins
Plugins are a way to enhance the basic elasticsearch functionality in a
custom manner. They range from adding custom mapping types, custom
analyzers (in a more built in fashion), native scripts, custom discovery
and more.
[float]
==== Installing plugins
Installing plugins can either be done manually by placing them under the
`plugins` directory, or using the `plugin` script. Several plugins can
be found under the https://github.com/elasticsearch[elasticsearch]
organization in GitHub, starting with `elasticsearch-`.
Starting from 0.90.2, installing plugins typically take the form of
`plugin --install <org>/<user/component>/<version>`. The plugins will be
automatically downloaded in this case from `download.elasticsearch.org`,
and in case they don't exist there, from maven (central and sonatype).
Note that when the plugin is located in maven central or sonatype
repository, `<org>` is the artifact `groupId` and `<user/component>` is
the `artifactId`.
For prior version, the older form is
`plugin -install <org>/<user/component>/<version>`
A plugin can also be installed directly by specifying the URL for it,
for example:
`bin/plugin --url file://path/to/plugin --install plugin-name` or
`bin/plugin -url file://path/to/plugin -install plugin-name` for older
version.
Starting from 0.90.2, for more information about plugins, you can run
`bin/plugin -h`.
[float]
==== Site Plugins
Plugins can have "sites" in them, any plugin that exists under the
`plugins` directory with a `_site` directory, its content will be
statically served when hitting `/_plugin/[plugin_name]/` url. Those can
be added even after the process has started.
Installed plugins that do not contain any java related content, will
automatically be detected as site plugins, and their content will be
moved under `_site`.
The ability to install plugins from Github allows to easily install site
plugins hosted there by downloading the actual repo, for example,
running:
[source,js]
--------------------------------------------------
# From 0.90.2
bin/plugin --install mobz/elasticsearch-head
bin/plugin --install lukas-vlcek/bigdesk
# From a prior version
bin/plugin -install mobz/elasticsearch-head
bin/plugin -install lukas-vlcek/bigdesk
--------------------------------------------------
Will install both of those site plugins, with `elasticsearch-head`
available under `http://localhost:9200/_plugin/head/` and `bigdesk`
available under `http://localhost:9200/_plugin/bigdesk/`.
[float]
==== Mandatory Plugins
If you rely on some plugins, you can define mandatory plugins using the
`plugin.mandatory` attribute, for example, here is a sample config:
[source,js]
--------------------------------------------------
plugin.mandatory: mapper-attachments,lang-groovy
--------------------------------------------------
For safety reasons, if a mandatory plugin is not installed, the node
will not start.
