ElasticsStak是elatic公司推出的一些列技术栈,早期有一个比较响亮的名字叫"ELK"用于日志采集系统,后续由于对该组件的扩充,引入很多新的组件,比如beats,xpack及云原生相关的组件,最终统称为elasticstack。

温馨提示:
如果你的集群不正常工作,执行如下操作
(1)集群所有节点停止服务
systemctl stop elasticsearch
pkill java
(2)确保停止服务完成,可以执行"ss -ntl"查看监听端口是否存在或者是查看java
ss -ntl
ps -ef | grep java
(3)删除集群默认的数据
rm -rf /var/lib/elasticsearch/* /var/log/elasticsearch/* /tmp/*
(4)重新启动集群即可
