这里将集成的过程及遇到的问题分享给大家，欢迎指出纠正
目标：集成两台机器上的三个节点，一台服务器上装一个es，另一个机器上安装两个es
配置文件：
三个es的elasticsearch.yml配置如下：
主节点
cluster.name: my-application
node.name: node-1
network.host: 10.10.129.21
http.port: 9200
#transport.tcp.port:9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.master: true
node.data: true
discovery.zen.ping.unicast.hosts: ["10.10.129.19","10.10.129.21"]
同一台机器的附节点：
cluster.name: my-application
node.name: node-2
network.host: 10.10.129.21
http.port: 9500
#transport.tcp.port:9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.data: true
discovery.zen.ping.unicast.hosts: ["10.10.129.21","10.10.129.19"]
另外一台机器的节点付：
cluster.name: my-application
node.name: node-12
network.host: 10.10.129.19
http.port: 9200
#transport.tcp.port:9300
http.cors.enabled: true
http.cors.allow-origin: "*"
node.data: true
discovery.zen.ping.unicast.hosts: ["10.10.129.21"]
head插件修改head/_site/app.js
this.base_uri = this.config.base_uri || "http://10.10.129.21:9200";
因为this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";中this.prefs.get("app-base_uri") 返回的值是“http://localhost:9200”，没找到在哪，所以果断去掉（这个地方弄了许久，因为网上搜的都是把localhost直接换成ip，但是this.prefs.get("app-base_uri")返回值了）
head/Gruntfile.js修改：connect: {
server: {
options: {
hostname:'*',
port: 9100,
base: '.',
keepalive: true
}
}
}
注意：三个es的版本必须一致！！！！不然连不上，网上报x-pack的错误，但是我并没有装这个插件

版本一致就好了
