1、Elasticsearch下载安装

https://www.elastic.co/cn/downloads/elasticsearch

解压：

2、安装head

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

This package has installed:

• Node.js v10.13.0 to /usr/local/bin/node
• npm v6.4.1 to /usr/local/bin/npm

Make sure that /usr/local/bin is in your $PATH.

houzhibindeMacBook-Pro:bin houzhibin$ npm install -g grunt -cli
npm WARN checkPermissions Missing write access to /usr/local/lib/node_modules
npm ERR! path /usr/local/lib/node_modules

npm ERR!

没权限，解决：sudo chown -R $(whoami) /usr/local/lib/node_modules

然后再

npm install -g grunt  -cli

成功

----------装head-----------

npm install

-----------运行head------------

grunt server，启动head服务，如下所示则为启动成功。（可以到head根目录下修改Gruntfile.js文件的启动端口，默认是9100）

http://localhost:9100

然后去修改elasticsearch的配置文件，elasticsearch安装目录/config/elasticsearch.yml，打开文件后在末端另起一行分别顶格添加如下两行红色字体文本，保存后重启elasticsearch.bat。图片是我的elasticsearch配置，提供给你参考下。

1 http.cors.enabled: true

2 http.cors.allow-origin: "*"

重启elastic

houzhibindeMacBook-Pro:self houzhibin$ cd elasticsearch-6.5.1/bin
houzhibindeMacBook-Pro:bin houzhibin$ ./elasticsearch

连接，试试：
再次启动head的命令：

houzhibindeMacBook-Pro:local houzhibin$ cd ~/self/elasticsearch-head-master
houzhibindeMacBook-Pro:elasticsearch-head-master houzhibin$ grunt server
