Kafka无法在ubuntu实例上启动，getLocalHost（InetAddress）返回带有“的ip”；知识产权；附加到ip的开头

在AWS上运行ubuntu。当我尝试启动卡夫卡时，我看到了以下例外：

从我开始使用这张图片开始，我就注意到了这一点：

ubuntu@ip-10-153-166-139:

---

为什么kafka服务器试图使用“ip”来完全启动实例ip？是否有可以更改的系统配置，以便getLocalHost只返回ip本身？

如上所述，答案如下：

Inside/kafka/config/server.properties添加：

---

host.name='actual.ip.of.the.box'

ip-10-153-166-139是解析为EC2实例的主专用IPv4地址的内部DNS主机名。看看这个问题的答案是否有帮助：显示您的Kafka服务器属性file@mazaneicha正是我需要的，非常感谢。
