一、简介：
elasticsearch-head是一个用于浏览ElasticSearch集群并与其进行交互的Web项目
GitHub托管地址：https://github.com/mobz/elasticsearch-head
二、安装
1、插件安装(我这里以新版本为主):
从ElasticSearch5.x开始 不在支持 插件方式启动 必须作为独立服务器运行
对于Elasticsearch 2.x： sudo elasticsearch/bin/plugin install mobz/elasticsearch-head
对于Elasticsearch 1.x： sudo elasticsearch/bin/plugin -install mobz/elasticsearch-head/1.x
对于Elasticsearch 0.x： sudo elasticsearch/bin/plugin -install mobz/elasticsearch-head/0.9
2、浏览器插件（Chrome扩展程序)
地址：https://chrome.google.com/webstore/detail/elasticsearch-head/ffmkiejjmecolpfloofpjologoblkegm/
CSDN:点击下载
下载后解压 拖到浏览器完成安装
如图:
3、作为服务安装在服务器
需要环境：Node.js
1>、安装Node.js
[root@gameServer ~]# cd /usr/local/

2>、下载Head插件
[root@gameServer local]# su payment
[payment@gameServer local]$ cd ~/elasticSearch/
[payment@gameServer elasticSearch]$ ll

3>、编译启动
别的博客有推荐
#使用淘宝的镜像库进行下载，速度很快
npm config set registry https://registry.npm.taobao.org
我这里不建议使用：我在使用过程中、出现了找不到包
我用的官网的
npm config set registry http://registry.cnpmjs.org
[payment@gameServer elasticsearch-head]$ npm config set registry http://registry.cnpmjs.org
[payment@gameServer elasticsearch-head]$
[payment@gameServer elasticsearch-head]$ npm install

[payment@gameServer elasticsearch-head]$
[payment@gameServer elasticsearch-head]$ npm run start
> elasticsearch-head@0.0.0 start /home/payment/elasticSearch/elasticsearch-head
> grunt server
(node:9942) ExperimentalWarning: The http2 module is an experimental API.
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:9100
修改配置：并且后台启动
[payment@gameServer elasticsearch-head]$ pwd
/home/payment/elasticSearch/elasticsearch-head
[payment@gameServer elasticsearch-head]$ vim Gruntfile.js
# 找到并修改如下配置
connect: {
server: {
options: {
port: 9100,
base: '.',
keepalive: true,
hostname: '*'
}
}
}
[payment@gameServer elasticsearch-head]$ vim _site/app.js
# 找到如下配置并修改：
this.base_uri = this.config.base_uri || this.prefs.get("app-base_uri") || "http://172.17.63.15:9200";
[payment@gameServer elasticsearch-head]$ npm run start &
三、ElasticSeatch修改配置(已经配置的忽略此步)
连接到elasticsearch
默认情况下，elasticsearch会在弹性搜索头连接的端口9200上公开一个http rest API。
在elasticsearch中启用CORS
当不作为elasticsearch的插件运行时，您必须在elasticsearch中启用CORS，否则您的浏览器将拒绝跨域。
在elasticsearch配置中;
加 http.cors.enabled: true
您还必须设置，http.cors.allow-origin因为默认情况下不允许跨域。http.cors.allow-origin: "*" 是允许配置的，但由于这样配置的任何地方都可以访问，所以有安全风险。
我在集群安装的时候已经配好了、如果你刚配置、需要重启ElasticSearch服务
http.cors.enabled: true
http.cors.allow-origin: "*"
四、测试head插件(选择你对应的安装方式)
1、测试浏览器插件
点击插件按钮进入页面
修改链接地址:链接集群 你可以看到节点信息 以及状态
2、测试服务安装的插件
进入：http://ip地址:9100(如图)
到这里 ElasticSearch Head插件就彻底安装OK了
