You have installed some plugins and now you need to remove a plugin because it's not required. Removing an Elasticsearch plugin is easy to uninstall if everything goes right, otherwise you need to manually remove it.
This recipe covers both cases.
You need a working Elasticsearch installation as we described in the Downloading and installing Elasticsearch recipe and a prompt/shell to execute commands in Elasticsearch install directory. Before removing a plugin, it is safer to stop Elasticsearch server to prevent error due to the deletion of plugin JAR.
The steps to remove a plugin are as follows:
- Stop your running node to prevent exceptions caused due to removal of a file.
- Using the Elasticsearch plugin manager, which comes with its script wrapper (plugin).
On Linux and MacOSX, type the following command:
elasticsearch-plugin remove lang-python
On Windows, type the following command:
elasticsearch-plugin.bat remove lang-python
- Restart the server.
The plugin manager's remove command tries to detect the correct name of the plugin and to remove the directory of the installed plugin.
If there are undeletable files on your plugin directory (or strange astronomical events that hits your server), the plugin script might fail to manually remove a plugin you need to follow these steps:
- Go into the plugins directory
- Remove the directory with your plugin name
