amazon-ec2 - 为什么我无法从外部连接到 Kafka？

Question

我正在 ec2 实例上运行 kafka。所以amazon ec2实例有两个ip，一个是内部ip，第二个是外部使用的。

我从本地计算机创建了生产者，但它重定向到内部 IP 并给出连接失败错误。任何人都可以帮助我在 ec2 实例上配置 kafka，以便我可以从本地计算机运行生产者。我尝试了很多组合但没有成功。

在 Kafka FAQ (更新新属性)您可以阅读:

When a broker starts up, it registers its ip/port in ZK. You need to make sure the registered ip is consistent with what's listed in bootstrap.servers in the producer config. By default, the registered ip is given by InetAddress.getLocalHost.getHostAddress(). Typically, this should return the real ip of the host. However, sometimes (e.g., in EC2), the returned ip is an internal one and can't be connected to from outside. The solution is to explicitly set the host ip and port to be registered in ZK by setting the advertised.listeners property in server.properties.
