1、去官网下载最新软件
选择zip包，https://www.elastic.co/downloads/elasticsearch
2、下载node
必须 > 6.0已上
3、解压elasticsearch压缩包
4、修改config下的elasticsearch.yml
注意：每个“:”后都必须有个空格
5、去 https://github.com/mobz/elasticsearch-head 下载head插件
插件放到plugins目录文件下
6、进入 head文件内 修改配置
修改_site/app.js
修改 Gruntfile.js
7、使用npm 安装head需要的包
cd elasticsearch-headnpm installnpm run start
8、启动elasticsearch
有点尴尬，报错了。
9、解决报错

因为 missing for plugin [head]，意思是找不到head插件。
从官方文档中，6.2版本需要将head插件放到elasticsearch目录中,所以，将head目录文件剪切拿到上一层目录中
10、启动软件
，再点击elasticsearch.bat
这样就完成下载和配置head插件了。
