Kafka 启动报错java.io.IOException: Can't resolve address.

阿里云上 部署Kafka 启动报错java.io.IOException: Can't resolve address.

本地调试的,报错

需要在本地添加阿里云主机的 host 映射

linux kafka server 192.168.0.141 hostname bogon

在windows

java 代码

package myzookeeper;

import java.util.Properties;

import org.apache.kafka.clients.producer.KafkaProducer;

import org.apache.kafka.clients.producer.Producer;

import org.apache.kafka.clients.producer.ProducerRecord;

public class myCustomer {

public static void  main(String[] args) {

Properties props = new Properties();  

        props.put("bootstrap.servers", "192.168.0.141:9092");  

        props.put("key.serializer", "org.apache.kafka.common.serialization.StringSerializer");  

        props.put("value.serializer", "org.apache.kafka.common.serialization.StringSerializer");  

        Producer producer = new KafkaProducer<>(props);  

        producer.send(new ProducerRecord<>("mytopic", "axxxx", "axxxx"));

        System.out.println("1");

        producer.close();  

}

}

报错 Error connecting to node 0 at bogon:9092:

不能解析bogon

kafka 连接原理

首先连接 192.168.0.141:9092

再连接返回的host.name = bogon,

最后继续连接advertised.host.name=bogon

解决办法

添加window解析

hosts 文件增加 

192.168.0.141 bogon

用cmd ping bogon 试试如果可以ping通即可。
