解决

原因：线程占用

解决：重新启动

step1:杀死elasticsearch线程

ps -ef | grep elastic

kill -9 XXX

修改 elasticsearch-head 目录下的 Gruntfile.js 文件，在 options 属性内增加 hostname，设置为 0.0.0.0。

connect: {

    server: {

        options: {

            hostname: '0.0.0.0',

            port: 9100,

            base: '.',

            keepalive: true

        }

    }

}
