elasticsearch 伪集群部署

1. 环境准备

IP	主机名	安装软件	操作系统
192.168.2.20	master	es，jdk1.8	ubuntu18.04

我们部署ELK 5.X 本文介绍伪集群部署，也就是单个机器上跑多个es组成的集群

2. 伪集群启动

/opt/elasticsearch/bin/elasticsearch &
/opt/elasticsearch/bin/elasticsearch -Ehttp.port=8200 -Epath.data=node1 &
/opt/elasticsearch/bin/elasticsearch -Ehttp.port=7200 -Epath.data=node2 &

查看集群状态

curl master:8200/_cat/nodes?v
