本文介绍了在使用Kafka时遇到的连接问题及其解决方案。问题出现在尝试连接到Broker时，由于配置文件中指定的主机名与实际使用的命令不匹配导致。通过调整命令中的主机名与配置文件保持一致，成功解决了这一问题。

kafka连接生产者（消费者其实也一样的问题）出现了下面这个报错：（

WARN [Producer clientId=console-producer] Connection to node -1 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

找到配置文件


在配置plaintext的时候，地址配置的是master（master是我在/etc/hosts文件里面配置的127.0.0.1），而我连接的时候，使用的是：

 bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test

改为：

 bin/kafka-console-producer.sh --broker-list master:9092 --topic test

perfect，完美的解决了（生产者也一样哦）

真的很奇怪，为什么不能自动转换过来

Kafka上手时，为了测试简单的「生产者-消费者」，于是利用Kafka中的kafka-topics.sh创建了一个topic:topic_1后进行测试。 测试语句如下： 生产者：kafka-console-producer.sh --broker-list localhost:9092 --topic topic_1 消费者：kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topic_1 原本以为会如期出现生产者发送

一般是IP和端口的配置问题，建议查看一下 意思是连不上Kafka，我启动了虚拟机之后，启动项目，运行程序之后报这个错误，一开始没想起来，网上找了一些类似的问题和解决问题，差不多都和IP地址相关，我后来想起来，项目中的application.yml文件中，关于Kafka的bootstrap-servers: 虚拟机地址:9092 配置改为了自己的虚拟机地址，原来是：bootstrap-servers: 127.0.0.1:9092，改过之后，重新启动项目，调试接口，能够正常运行。我的Kafka配置文件：
