Apache kafka 访问远程计算机中的kafka代理时出错

我在172.19.91.125运行zookeeper和大部分kafka服务器。这台机器上所有的东西我都运转得很好

但当我尝试与消费者一起访问172.19.101.61上的卡夫卡服务时：

bin/kafka-console-consumer.sh --zookeeper 172.19.91.125:2181 --from-beginning --topic my-topic

我收到以下错误消息：

一定是配置问题，是不是有人遇到了同样的问题？

最后，我自己解决了

因为我别无选择，只能检查源代码，即使我对Java/scala也知之甚少

我发现主机：linux，端口：9100是一个代理套接字信息，它应该打印一些ip地址。我想那一定是主人的错

---

然后我将configuration server.properties、所有host.name字段更改为IP并重新启动它们，效果很好

如果您配置了DNS，它还应该与主机名一起工作。这就是我们在生产系统中使用的方式。
