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
        }
    }
}
