检查集群状态 http://192.168.1.200:9200/_cluster/health?pretty=true http://192.168.1.201:9200/_cluster/health?pretty=true http://192.168.1.202:9200/_cluster/health?pretty=true
安装head： 从5开始，head不再是一个插件形式安装，head作为独立的一个服务，需要单独安装：
yum install git -y
cd /home/elasticsearch-5.3.0/
git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install -g grunt #(执行这条之前请看下面注意)
注意：目前centos7还不能用yum安装nodejs和npm，需要手动安装
安装nodejs：
去这里下载编译好的包，https://nodejs.org/download/release/latest-v7.x/
然后解压，把里面的bin添加到path即可
安装npm：
#使用如下命令（https://docs.npmjs.com/README#fancy-install-unix- 这个网址中有说明）
sudo curl -L https://npmjs.org/install.sh | sh
修改elasticsearch-head的连接地址: 目录：elasticsearch-head/_site/app.js
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://localhost:9200";
把localhost修改成你es的服务器地址，如:
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://192.168.1.x:9200";
cd /home/elasticsearch-5.3.0/elasticsearch-head/
执行npm install下载依赖的包：(这句其实不用也行)
npm install
启动：
nohup grunt server &
