插件能额外扩展elasticsearch功能,提供各类功能等等。有三种类型的插件:
- java插件
只包含JAR文件,必须在集群中每个节点上安装而且需要重启才能使插件生效。 - 网站插件
这类插件包含静态web内容,如js、css、html等等,可以直接从elasticsearch服务,如head插件。只需在一个节点上安装,不需要重启服务。可以通过下面的URL访问,如:http://node-ip:9200/_plugin/plugin_name - 混合插件
顾名思义,就是包含上面两种的插件。

关于插件更多内容参见:https://www.elastic.co/guide/en/elasticsearch/plugins/2.0/index.html
elasticsearch的内容暂且更新这么多了,转到kibana上去了,目前这些内容够你摆弄ELK。后面再回过头来继续elasticsearch内容,如增删查改等等。
