CentOS7 上搭建多节点 Elasticsearch集群

wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-6.4.2.tar.gz

mkdir /opt/elasticsearch
将压缩包复制到该目录下并解压

cluster.name: codesheep         # 集群名称
node.name: sheep1                 # 节点名
network.host: 192.168.31.8     # 绑定的节点1地址
network.bind_host: 0.0.0.0      # 此项不设置你试试本机可能访问不了啊
discovery.zen.ping.unicast.hosts: ["192.168.31.8","192.168.31.9"]  # hosts列表
discovery.zen.minimum_master_nodes: 1 

## 如下配置是为了解决 Elasticsearch可视化工具 dejavu的跨域问题！若不用可视化 工具 则可省略之
