== Plugin Management
|
|
|
|
The `plugin` script is used to install, list, and remove plugins. It is
|
|
located in the `$ES_HOME/bin` directory by default but it may be in a
|
|
{ref}/setup-dir-layout.html[different location] if you installed Elasticsearch
|
|
with an RPM or deb package.
|
|
|
|
Run the following command to get usage instructions:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin -h
|
|
-----------------------------------
|
|
|
|
[[installation]]
|
|
=== Installing Plugins
|
|
|
|
The documentation for each plugin usually includes specific installation
|
|
instructions for that plugin, but below we document the various available
|
|
options:
|
|
|
|
[float]
|
|
=== Core Elasticsearch plugins
|
|
|
|
Core Elasticsearch plugins can be installed as follows:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install [plugin_name]
|
|
-----------------------------------
|
|
|
|
For instance, to install the core <<analysis-icu,ICU plugin>>, just run the
|
|
following command:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install analysis-icu
|
|
-----------------------------------
|
|
|
|
This command will install the version of the plugin that matches your
|
|
Elasticsearch version.
|
|
|
|
[float]
|
|
=== Community and non-core plugins
|
|
|
|
Non-core plugins provided by Elasticsearch, or plugins provided by the
|
|
community, can be installed from `download.elastic.co`, from Maven (Central
|
|
and Sonatype), or from GitHub. In this case, the command is as follows:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install [org]/[user|component]/[version]
|
|
-----------------------------------
|
|
|
|
For instance, to install the https://github.com/lmenezes/elasticsearch-kopf[Kopf]
|
|
plugin from GitHub, run one of the following commands:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install lmenezes/elasticsearch-kopf <1>
|
|
sudo bin/plugin install lmenezes/elasticsearch-kopf/1.x <2>
|
|
-----------------------------------
|
|
<1> Installs the latest version from GitHub.
|
|
<2> Installs the 1.x version from GitHub.
|
|
|
|
When installing from Maven Central/Sonatype, `[org]` should be replaced by
|
|
the artifact `groupId`, and `[user|component]` by the `artifactId`. For
|
|
instance, to install the
|
|
https://github.com/elastic/elasticsearch-mapper-attachments[mapper attachment]
|
|
plugin from Sonatype, run:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install org.elasticsearch/elasticsearch-mapper-attachments/2.6.0 <1>
|
|
-----------------------------------
|
|
<1> When installing from `download.elastic.co` or from Maven Central/Sonatype, the
|
|
version is required.
|
|
|
|
[float]
|
|
=== Custom URL or file system
|
|
|
|
A plugin can also be downloaded directly from a custom location by specifying the URL:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install [plugin-name] --url [url] <1>
|
|
-----------------------------------
|
|
<1> Both the URL and the plugin name must be specified.
|
|
|
|
For instance, to install a plugin from your local file system, you could run:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install my_plugin --url file:/path/to/plugin.zip
|
|
-----------------------------------
|
|
|
|
[[listing-removing]]
|
|
=== Listing and Removing Installed Plugins
|
|
|
|
[float]
|
|
=== Listing plugins
|
|
|
|
A list of the currently loaded plugins can be retrieved with the `list` option:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin list
|
|
-----------------------------------
|
|
|
|
Alternatively, use the {ref}/cluster-nodes-info.html[node-info API] to find
|
|
out which plugins are installed on each node in the cluster
|
|
|
|
[float]
|
|
=== Removing plugins
|
|
|
|
Plugins can be removed manually, by deleting the appropriate directory under
|
|
`plugins/`, or using the public script:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin remove [pluginname]
|
|
-----------------------------------
|
|
|
|
=== Other command line parameters
|
|
|
|
The `plugin` scripts supports a number of other command line parameters:
|
|
|
|
[float]
|
|
=== Silent/Verbose mode
|
|
|
|
The `--verbose` parameter outputs more debug information, while the `--silent`
|
|
parameter turns off all output. The script may return the following exit
|
|
codes:
|
|
|
|
[horizontal]
|
|
`0`:: everything was OK
|
|
`64`:: unknown command or incorrect option parameter
|
|
`74`:: IO error
|
|
`70`:: any other error
|
|
|
|
[float]
|
|
=== Custom config directory
|
|
|
|
If your `elasticsearch.yml` config file is in a custom location, you will need
|
|
to specify the path to the config file when using the `plugin` script. You
|
|
can do this as follows:
|
|
|
|
[source,sh]
|
|
---------------------
|
|
sudo bin/plugin -Des.path.conf=/path/to/custom/config/dir install <plugin name>
|
|
---------------------
|
|
|
|
You can also set the `CONF_DIR` environment variable to the custom config
|
|
directory path.
|
|
|
|
[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
|
|
sudo bin/plugin install mobz/elasticsearch-head --timeout 30s
|
|
|
|
# Wait for 1 minute before failing
|
|
sudo bin/plugin install mobz/elasticsearch-head --timeout 1m
|
|
|
|
# Wait forever (default)
|
|
sudo bin/plugin install mobz/elasticsearch-head --timeout 0
|
|
-----------------------------------
|
|
|
|
[float]
|
|
=== Proxy settings
|
|
|
|
To install a plugin via a proxy, you can pass the proxy details in with the
|
|
Java settings `proxyHost` and `proxyPort`. On Unix based systems, these
|
|
options can be set on the command line:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
sudo bin/plugin install mobz/elasticsearch-head -DproxyHost=host_name -DproxyPort=port_number
|
|
-----------------------------------
|
|
|
|
On Windows, they need to be added to the `JAVA_OPTS` environment variable:
|
|
|
|
[source,shell]
|
|
-----------------------------------
|
|
set JAVA_OPTS="-DproxyHost=host_name -DproxyPort=port_number"
|
|
bin/plugin install mobz/elasticsearch-head
|
|
-----------------------------------
|
|
|
|
=== Settings related to plugins
|
|
|
|
[float]
|
|
=== Custom plugins directory
|
|
|
|
The `plugins` directory can be changed from the default by adding the
|
|
following to the `elasticsearch.yml` config file:
|
|
|
|
[source,yml]
|
|
---------------------
|
|
path.plugins: /path/to/custom/plugins/dir
|
|
---------------------
|
|
|
|
The default location of the `plugins` directory depends on
|
|
{ref}/setup-dir-layout.html[which package you install].
|
|
|
|
[float]
|
|
=== Mandatory Plugins
|
|
|
|
If you rely on some plugins, you can define mandatory plugins by adding
|
|
`plugin.mandatory` setting to the `config/elasticsearch.yml` file, for
|
|
example:
|
|
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
plugin.mandatory: mapper-attachments,lang-groovy
|
|
--------------------------------------------------
|
|
|
|
For safety reasons, a node will not start if it is missing a mandatory plugin.
|
|
|
|
[float]
|
|
=== Lucene version dependent plugins
|
|
|
|
For some plugins, such as analysis plugins, a specific major Lucene version is
|
|
required to run. In that case, the plugin provides in its
|
|
`es-plugin.properties` file the Lucene version for which the plugin was built for.
|
|
|
|
If present at startup the node will check the Lucene version before loading
|
|
the plugin. You can disable that check using
|
|
|
|
[source,yaml]
|
|
--------------------------------------------------
|
|
plugins.check_lucene: false
|
|
--------------------------------------------------
|
|
