[[modules-plugins]] == Plugins [float] === 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]] ==== 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 // ----------------------------------- 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, `` is the artifact `groupId` and `` 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 <>. [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 ----------------------------------- [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] [[known-plugins]] === Known Plugins [float] [[analysis-plugins]] ==== Analysis Plugins .Supported by Elasticsearch * https://github.com/elasticsearch/elasticsearch-analysis-icu[ICU Analysis plugin] * https://github.com/elasticsearch/elasticsearch-analysis-kuromoji[Japanese (Kuromoji) Analysis plugin]. * https://github.com/elasticsearch/elasticsearch-analysis-smartcn[Smart Chinese Analysis Plugin] * https://github.com/elasticsearch/elasticsearch-analysis-stempel[Stempel (Polish) Analysis plugin] .Supported by the community * https://github.com/barminator/elasticsearch-analysis-annotation[Annotation Analysis Plugin] (by Michal Samek) * https://github.com/yakaz/elasticsearch-analysis-combo/[Combo Analysis Plugin] (by Olivier Favre, Yakaz) * https://github.com/jprante/elasticsearch-analysis-hunspell[Hunspell Analysis Plugin] (by Jörg Prante) * https://github.com/medcl/elasticsearch-analysis-ik[IK Analysis Plugin] (by Medcl) * https://github.com/suguru/elasticsearch-analysis-japanese[Japanese Analysis plugin] (by suguru). * https://github.com/medcl/elasticsearch-analysis-mmseg[Mmseg Analysis Plugin] (by Medcl) * https://github.com/chytreg/elasticsearch-analysis-morfologik[Morfologik (Polish) Analysis plugin] (by chytreg) * https://github.com/imotov/elasticsearch-analysis-morphology[Russian and English Morphological Analysis Plugin] (by Igor Motov) * https://github.com/medcl/elasticsearch-analysis-pinyin[Pinyin Analysis Plugin] (by Medcl) * https://github.com/medcl/elasticsearch-analysis-string2int[String2Integer Analysis Plugin] (by Medcl) [float] [[river]] ==== River Plugins .Supported by Elasticsearch * https://github.com/elasticsearch/elasticsearch-river-couchdb[CouchDB River Plugin] * https://github.com/elasticsearch/elasticsearch-river-rabbitmq[RabbitMQ River Plugin] * https://github.com/elasticsearch/elasticsearch-river-twitter[Twitter River Plugin] * https://github.com/elasticsearch/elasticsearch-river-wikipedia[Wikipedia River Plugin] .Supported by the community * https://github.com/domdorn/elasticsearch-river-activemq/[ActiveMQ River Plugin] (by Dominik Dorn) * https://github.com/albogdano/elasticsearch-river-amazonsqs[Amazon SQS River Plugin] (by Alex Bogdanovski) * https://github.com/xxBedy/elasticsearch-river-csv[CSV River Plugin] (by Martin Bednar) * http://www.pilato.fr/dropbox/[Dropbox River Plugin] (by David Pilato) * http://www.pilato.fr/fsriver/[FileSystem River Plugin] (by David Pilato) * https://github.com/obazoud/elasticsearch-river-git[Git River Plugin] (by Olivier Bazoud) * https://github.com/sksamuel/elasticsearch-river-hazelcast[Hazelcast River Plugin] (by Steve Samuel) * https://github.com/jprante/elasticsearch-river-jdbc[JDBC River Plugin] (by Jörg Prante) * https://github.com/qotho/elasticsearch-river-jms[JMS River Plugin] (by Steve Sarandos) * https://github.com/endgameinc/elasticsearch-river-kafka[Kafka River Plugin] (by Endgame Inc.) * https://github.com/tlrx/elasticsearch-river-ldap[LDAP River Plugin] (by Tanguy Leroux) * https://github.com/richardwilly98/elasticsearch-river-mongodb/[MongoDB River Plugin] (by Richard Louapre) * https://github.com/sksamuel/elasticsearch-river-neo4j[Neo4j River Plugin] (by Steve Samuel) * https://github.com/jprante/elasticsearch-river-oai/[Open Archives Initiative (OAI) River Plugin] (by Jörg Prante) * https://github.com/sksamuel/elasticsearch-river-redis[Redis River Plugin] (by Steve Samuel) * http://dadoonet.github.com/rssriver/[RSS River Plugin] (by David Pilato) * https://github.com/adamlofts/elasticsearch-river-sofa[Sofa River Plugin] (by adamlofts) * https://github.com/javanna/elasticsearch-river-solr/[Solr River Plugin] (by Luca Cavanna) * https://github.com/sunnygleason/elasticsearch-river-st9[St9 River Plugin] (by Sunny Gleason) * https://github.com/plombard/SubversionRiver[Subversion River Plugin] (by Pascal Lombard) [float] [[transport]] ==== Transport Plugins .Supported by Elasticsearch * https://github.com/elasticsearch/elasticsearch-transport-memcached[Memcached transport plugin] * https://github.com/elasticsearch/elasticsearch-transport-thrift[Thrift Transport] * https://github.com/elasticsearch/elasticsearch-transport-wares[Servlet transport] .Supported by the community * https://github.com/tlrx/transport-zeromq[ZeroMQ transport layer plugin] (by Tanguy Leroux) * https://github.com/sonian/elasticsearch-jetty[Jetty HTTP transport plugin] (by Sonian Inc.)
