[[plugin-management]] == 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 different location depending on which Elasticsearch package you installed: * {ref}/zip-targz.html#zip-targz-layout[Directory layout of `.zip` and `.tar.gz` archives] * {ref}/deb.html#deb-layout[Directory layout of Debian package] * {ref}/rpm.html#rpm-layout[Directory layout of RPM] Run the following command to get usage instructions: [source,shell] ----------------------------------- sudo bin/elasticsearch-plugin -h ----------------------------------- [IMPORTANT] .Running as root ===================== If Elasticsearch was installed using the deb or rpm package then run `/usr/share/elasticsearch/bin/elasticsearch-plugin` as `root` so it can write to the appropriate files on disk. Otherwise run `bin/elasticsearch-plugin` as the user that owns all of the Elasticsearch files. ===================== [[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/elasticsearch-plugin install [plugin_name] ----------------------------------- For instance, to install the core <>, just run the following command: [source,shell] ----------------------------------- sudo bin/elasticsearch-plugin install analysis-icu ----------------------------------- This command will install the version of the plugin that matches your Elasticsearch version and also show a progress bar while downloading. [[plugin-management-custom-url]] === Custom URL or file system A plugin can also be downloaded directly from a custom location by specifying the URL: [source,shell] ----------------------------------- sudo bin/elasticsearch-plugin install [url] <1> ----------------------------------- <1> must be a valid URL, the plugin name is determined from its descriptor. For instance, to install a plugin from your local file system, you could run: [source,shell] ----------------------------------- sudo bin/elasticsearch-plugin install file:///path/to/plugin.zip ----------------------------------- The plugin script will refuse to talk to an HTTPS URL with an untrusted certificate. To use a self-signed HTTPS cert, you will need to add the CA cert to a local Java truststore and pass the location to the script as follows: [source,shell] ----------------------------------- sudo ES_JAVA_OPTS="-Djavax.net.ssl.trustStore=/path/to/trustStore.jks" bin/elasticsearch-plugin install https://.... ----------------------------------- [[listing-removing-updating]] === Listing, Removing and Updating Installed Plugins [float] === Listing plugins A list of the currently loaded plugins can be retrieved with the `list` option: [source,shell] ----------------------------------- sudo bin/elasticsearch-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/elasticsearch-plugin remove [pluginname] ----------------------------------- After a Java plugin has been removed, you will need to restart the node to complete the removal process. By default, plugin configuration files (if any) are preserved on disk; this is so that configuration is not lost while upgrading a plugin. If you wish to purge the configuration files while removing a plugin, use `-p` or `--purge`. This can option can be used after a plugin is removed to remove any lingering configuration files. [float] === Updating plugins Plugins are built for a specific version of Elasticsearch, and therefore must be reinstalled each time Elasticsearch is updated. [source,shell] ----------------------------------- sudo bin/elasticsearch-plugin remove [pluginname] sudo bin/elasticsearch-plugin install [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 including the progress bar. 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] === Batch mode Certain plugins require more privileges than those provided by default in core Elasticsearch. These plugins will list the required privileges and ask the user for confirmation before continuing with installation. When running the plugin install script from another program (e.g. install automation scripts), the plugin script should detect that it is not being called from the console and skip the confirmation response, automatically granting all requested permissions. If console detection fails, then batch mode can be forced by specifying `-b` or `--batch` as follows: [source,shell] ----------------------------------- sudo bin/elasticsearch-plugin install --batch [pluginname] ----------------------------------- [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 CONF_DIR=/path/to/conf/dir bin/elasticsearch-plugin install --------------------- [float] === Proxy settings To install a plugin via a proxy, you can add the proxy details to the `ES_JAVA_OPTS` environment variable with the Java settings `http.proxyHost` and `http.proxyPort` (or `https.proxyHost` and `https.proxyPort`): [source,shell] ----------------------------------- sudo ES_JAVA_OPTS="-Dhttp.proxyHost=host_name -Dhttp.proxyPort=port_number -Dhttps.proxyHost=host_name -Dhttps.proxyPort=https_port_number" bin/elasticsearch-plugin install analysis-icu ----------------------------------- Or on Windows: [source,shell] ------------------------------------ set ES_JAVA_OPTS="-Dhttp.proxyHost=host_name -Dhttp.proxyPort=port_number -Dhttps.proxyHost=host_name -Dhttps.proxyPort=https_port_number" bin\elasticsearch-plugin install analysis-icu ------------------------------------ === Plugins directory The default location of the `plugins` directory depends on which package you install: * {ref}/zip-targz.html#zip-targz-layout[Directory layout of `.zip` and `.tar.gz` archives] * {ref}/deb.html#deb-layout[Directory layout of Debian package] * {ref}/rpm.html#rpm-layout[Directory layout of RPM] [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: analysis-icu,lang-js -------------------------------------------------- For safety reasons, a node will not start if it is missing a mandatory plugin.
