elasticsearch head 可视化工具 安装

es5.x以前，head是以插件的形势安装的，5.x以后做为独立的服务来运行的。如果把elasticsearch，理解成数据库的话，那么head就相当于数据库可视化管理工具。

1，安装elasticsearch head

$ git clone https://github.com/mobz/elasticsearch-head.git
$ cd elasticsearch-head
$ npm install
$ npm run start

> elasticsearch-head@0.0.0 start /Users/zhangying/es/elasticsearch-head
> grunt server

(node:22286) ExperimentalWarning: The http2 module is an experimental API.
Running "connect:server" (connect) task
Waiting forever...
Started connect web server on http://localhost:9100  //启动成功

2，配置elasticsearch.yml

http.cors.enabled: true
http.cors.allow-origin: "*"   //可以是具体IP

这一步很重要的，因为牵扯到跨域问题。如果不做会报以下错误：

Failed to load resource: Origin http://localhost:9100 is not allowed by Access-Control-Allow-Origin.

3，重新启动elasticsearch.
