本文准备搭建三节点 elasticsearch集群，elasticsearch版本：6.5.4，因此这里准备了三台 Linux CentOS 7机器，只需要简单通过Vmware克隆两台CentOS 7机器，并分别设置静态ip即可。

三台 CentOS 7分别启动elasticsearch

NodeName	Web端口
node-1	192.168.92.90:9200
node-2	192.168.92.91:9200
node-3	192.168.92.93:9200

并将三台Centos7主机名分别设置nodenode01，node02和node03，区别三台centos7机器

#node01主机名设置：
[elsearch@localhost ~]$ hostnamectl set-hostname node01
node01
[elsearch@node01 ~]$ ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.92.90  netmask 255.255.255.0  broadcast 192.168.92.255
        inet6 fe80::b889:1772:c306:ef8f  prefixlen 64  scopeid 0x20<link>
        inet6 fe80::72e0:4da:118d:13d9  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:07:43:5a  txqueuelen 1000  (Ethernet)
        RX packets 829  bytes 158380 (154.6 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 634  bytes 116833 (114.0 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

#node02主机名设置：
[elsearch@localhost ~]$ hostnamectl set-hostname node02
node02
[elsearch@node02 ~]$ ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.92.91  netmask 255.255.255.0  broadcast 192.168.92.255
        inet6 fe80::b889:1772:c306:ef8f  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:84:99:62  txqueuelen 1000  (Ethernet)
        RX packets 2195  bytes 323930 (316.3 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 466  bytes 52037 (50.8 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

#node03主机名设置：
[elsearch@localhost ~]$ hostnamectl set-hostname node03
node03
[elsearch@node03 ~]$ ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.92.92  netmask 255.255.255.0  broadcast 192.168.92.255
        inet6 fe80::22a3:7ced:1761:de8e  prefixlen 64  scopeid 0x20<link>
        inet6 fe80::b889:1772:c306:ef8f  prefixlen 64  scopeid 0x20<link>
        inet6 fe80::72e0:4da:118d:13d9  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:c9:f0:22  txqueuelen 1000  (Ethernet)
        RX packets 859  bytes 141277 (137.9 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 619  bytes 147363 (143.9 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

下面在三台Centos7机器上对应的elasticsearch.yml配置集群

[elsearch@node01 elasticsearch-6.5.4]$ vim config/elasticsearch.yml
#node01的配置：
cluster.name: es-itcast-cluster
node.name: node01
#设置node01为主节点
node.master: true
node.data: true
network.host: 0.0.0.0
http.port: 9200

http.cors.enabled: true
http.cors.allow-origin: "*"

[elsearch@node02 elasticsearch-6.5.4]$ vim config/elasticsearch.yml
#node02的配置：
