[hadoop@hadoop001 bin]$ ./grunt server
# 方法二：
[hadoop@hadoop001 elasticsearch-head]$ node_modules/grunt/bin/grunt server &
在 elasticsearch.yml添加如下内容
http.cors.enabled: true
http.cors.allow-origin: "*"
注意：启动elasticsearch-head后，可能看不见健康状态，需要用具体的IP地址或者主机名，不要用http://localhost:9200/
也可以配置环境变量

export PATH=${ELASTICSEARCH_HOME}/bin:$PATH
