|
=== 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.

|
|
==== 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-`.
|
|
|
|
Installing plugins typically take the following form:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
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`.
|
|
|
|
A plugin can also be installed directly by specifying the URL for it,
|
|
for example:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
bin/plugin --url file:///path/to/plugin --install plugin-name
|
|
-----------------------------------
|
|
|
|
|
|
You can run `bin/plugin -h`.
|
|
|
|
[float]
|
|
[[site-plugins]]
|
|
==== 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]
|
|
--------------------------------------------------
|
|
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.
|
|
|
|
[float]
|
|
==== Installed Plugins
|
|
|
|
A list of the currently loaded plugins can be retrieved using the
|
|
<<cluster-nodes-info,Node Info API>>.
|
|
|
|
[float]
|
|
==== Removing plugins
|
|
|
|
Removing plugins can either be done manually by removing them under the
|
|
`plugins` directory, or using the `plugin` script.
|
|
|
|
Removing plugins typically take the following form:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
plugin --remove <pluginname>
|
|
-----------------------------------
|
|
|
|
[float]
|
|
==== Silent/Verbose mode
|
|
|
|
When running the `plugin` script, you can get more information (debug mode) using `--verbose`.
|
|
On the opposite, if you want `plugin` script to be silent, use `--silent` option.
|
|
|
|
Note that exit codes could be:
|
|
|
|
* `0`: everything was OK
|
|
* `64`: unknown command or incorrect option parameter
|
|
* `74`: IO error
|
|
* `70`: other errors
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
bin/plugin --install mobz/elasticsearch-head --verbose
|
|
plugin --remove head --silent
|
|
-----------------------------------
|
|
|
|
[float]
|
|
==== Timeout settings
|
|
|
|
By default, the `plugin` script will wait indefinitely when downloading before failing.
|
|
The timeout parameter can be used to explicitly specify how long it waits. Here is some examples of setting it to
|
|
different values:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
# Wait for 30 seconds before failing
|
|
bin/plugin --install mobz/elasticsearch-head --timeout 30s
|
|
|
|
# Wait for 1 minute before failing
|
|
bin/plugin --install mobz/elasticsearch-head --timeout 1m
|
|
|
|
# Wait forever (default)
|
|
bin/plugin --install mobz/elasticsearch-head --timeout 0
|
|
-----------------------------------
|
|
|
|
added[1.1.0]
|
|
[float]
|
|
==== Plugins isolation
|
|
|
|
Since Elasticsearch 1.1, by default, each plugin is loaded in _isolation_ (in its dedicated `ClassLoader`) to avoid class clashes between the various plugins and their associated libraries. The default can be changed through the `plugins.isolation` property in `elasticsearch.yml`, by setting it to `false`:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
plugins.isolation: false
|
|
--------------------------------------------------
|
|
|
|
Do note that each plugin can specify its _mandatory_ isolation through the `isolation` property in its `es-plugin.properties` configuration. In this (rare) case, the plugin setting is used, overwriting whatever default used by Elasticsearch.
