HEAD插件安装

       elasticsearch-head 是用于监控Elasticsearch状态的客户端插件,包括数据可视化、执行增删改查操作等

安装步骤

      1.先安装Nodejs

      2.下载head源码

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

      3.安装依赖模块

         npm install

      4.启动服务

        npm run start

          

          

 HEAD使用步骤

        1.使用HEAD连接es集群的时候,es集群服务端默认不接受跨域请求,需要先修改es的配置文件然后重启服务

         

        修改elasticsearch所在目录中 config/elasticsearch.yml
        # 是否支持跨域
          http.cors.enabled: true
        # *表示支持所有域名
         http.cors.allow-origin: "*"
