Es集群搭建核心思想
1.配置相同集群名称
2.配置不同的节点ID
3.修改X台服务器elasticsearch.yml配置
服务器环境->准备三台服务器集群
服务器集群配置：
## 修改elasticsearch.yml文件
[[email protected] elasticsearch]# vim elasticsearch.yml
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
# 取消注释，修改节点集群名称，保证三台服务器节点集群名称相同
cluster.name: chenxi
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
# 取消注释，每个节点名称不一样，其他两台为node-2, node-3
node.name: node-1
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
# 取消注释，服务器IP地址
network.host: 192.168.0.1
# --------------------------------- Discovery ----------------------------------
#
# Pass an initial list of hosts to perform discovery when new node is started:
# The default list of hosts is ["127.0.0.1", "[::1]"]
# 取消注释，多个服务器集群IP
discovery.zen.ping.unicast.hosts: ["192.168.0.1","192.168.0.2","192.168.0.3"]
#
# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):
# 取消注释，设置最小主节点为1
discovery.zen.minimum_master_nodes: 1
###关闭防火墙###
注意克隆data文件会导致数据不同步
启动错误信息：
某台集群服务器报错 failed to send join request to master 时
解决办法：
清除每台服务器data文件
集群验证地址：
http://192.168.0.1:9200/_cat/nodes?pretty
如成功显示如下：
192.168.0.1 18 93 1 0.00 0.00 0.00 mdi * node-1
192.168.0.2 20 96 2 0.00 0.03 0.11 mdi - node-2
192.168.0.3 20 96 2 0.00 0.05 0.11 mdi - node-3
