四、安装ElasticSearch Head插件

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

https://github.com/mobz/elasticsearch-head

二、安装

sudo elasticsearch/bin/plugin install mobz/elasticsearch-head
sudo elasticsearch/bin/plugin -install mobz/elasticsearch-head/1.x
sudo elasticsearch/bin/plugin -install mobz/elasticsearch-head/0.9

（Chrome扩展程序)

#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

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;

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。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。

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

四、测试head插件(选择你对应的安装方式)

修改链接地址:链接集群你可以看到节点信息以及状态
