单节点环境搭建参考：[https://blog.csdn.net/qq\_38270106/article/details/84309702][https_blog.csdn.net_qq_38270106_article_details_84309702]

建议先搭建好单服务器，再clone两个服务器

### 环境准备：三台虚拟机 ###

> **node-1----------192.168.128.156**
> 
> **node-2----------192.168.128.157**
> 
> **node-3----------192.168.128.158**

### 修改配置文件 ###

> cd /usr/local/elasticsearch-6.4.3/config
> 
> vi elasticsearch.yml

### clone两台服务器：修改如下红色部分  ###

**cluster.name: my-elasticsearch  \#\#\#保证三台服务器节点集群名称相同**

**node.name: node-1 \#\#\#\# 每个节点名称不一样 其他两台为node-2 ,node-3**

**network.host: 192.168.128.156 \#\#\#\# 实际服务器ip地址**

**discovery.zen.ping.unicast.hosts: \["192.168.128.156", "192.168.128.157","192.168.128.158"\]  \#\#多个服务集群ip**

**discovery.zen.minimum\_master\_nodes: 1 \#\#\#集群最少master数量**

###  验证集群效果 ###

关闭防火墙 systemctl stop firewalld.service

注意

克隆data文件会导致数据不同步

报该错误解决办法

failed to send join request to master

因为克隆导致data文件也克隆呢，直接清除每台服务器data里面的node文件。

> cd /usr/local/elasticsearch-6.4.3/data
> 
> rm -rf nodes

### **分别启动三个服务器，访问 **[http://192.168.128.156:9200/\_cat/nodes?pretty][http_192.168.128.156_9200_cat_nodes_pretty] ###
