Introduction – Elasticsearch Plugins
In our previous tutorial, we discussed what is elasticsearch plugin and how to install it. Also we have discussed how to install elasticsearch and ELK stack on CentOS 7. Now, in this article we will see how to Listing, Removing and Updating elasticsearch installed plugin.
Following is the command to list of the currently loaded plugins,
[root@localhost elasticsearch]$ bin/elasticsearch-plugin list
Alternatively, use the node-info API to find out which plugins are installed on each node in the cluster.
Plugins can be removed manually, by deleting the appropriate directory under
plugins/, or using the following command:
[root@localhost elasticsearch]$ bin/elasticsearch-plugin remove [pluginname]
Note: After a 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
--purge. This can option can be used after a plugin is removed to remove any lingering configuration files.
Plugins are built for a specific version of Elasticsearch, and therefore must be reinstalled each time Elasticsearch is updated. Following is the command to update of the currently loaded plugins,
[root@localhost elasticsearch]$ bin/elasticsearch-plugin remove [pluginname] [root@localhost elasticsearch]$ bin/elasticsearch-plugin install [pluginname]
