3.安装head插件

yum -y install git npm
git clone git://github.com/mobz/elasticsearch-head.git
cd elasticsearch-head
npm install
npm install -g cnpm --registry=
修改head监听地址为内网
vim Gruntfile.js
connect: {
server: {
options: {
hostname:'172.16.230.198',
port: 9100,
base: '.',
keepalive: true
}
}
}
后台启动elasticsearch-head 插件
npm install grunt-cli
ln -s /usr/local/data/elasticsearch-head/node_modules/grunt/bin/grunt  /usr/bin/
grunt  server &

遇到的问题：head 插件无法连接es集群 显示集群健康值未连接
修改head的es监听地址

cd elasticsearch-head
vim _site/app.js

修改 『http://localhost:9200』字段到本机ES端口与IP

vim $ES_HOME$/config/elasticsearch.yml
# 增加如下字段
http.cors.enabled: true
http.cors.allow-origin: "*"

重启es 和head即可
