本文档详细记录了启动Kafka过程中遇到的问题，包括配置文件中的监听地址错误、启动命令位置不当、创建topic时访问地址错误，以及消费报错的情况，并提供了相应的解决办法，强调在监听、创建topic和消费时，IP地址需要保持一致。

问题1

启动kafka时报错

[2022-03-09 00:07:17,280] ERROR [KafkaServer id=1] Fatal error during KafkaServer startup. Prepare to shutdown (kafka.server.KafkaServer)
org.apache.kafka.common.KafkaException: Socket server failed to bind to a:9092: 无法指定被请求的地址.

        ... 11 more

原因：
server.properties配置文件中监听地址指向了一个
解决办法：
修改kafka/config/server.properties文件中的listeners=PLAINTEXT://hostname:9092，注意其中hostname应为本机的地址，也就是说应为每台机器的ip

问题2

[2022-03-09 00:02:37,098] ERROR Exiting Kafka due to fatal exception (kafka.Kafka$)

        at kafka.Kafka$.main(Kafka.scala:58)
        at kafka.Kafka.main(Kafka.scala)

原因：
启动命令位置不对
解决办法：
去kafka的根目录下启动

[root@b kafka]# bin/kafka-server-start.sh config/server.properties

问题3

创建topic时报错

Error while executing topic command : Replication factor: 1 larger than available brokers: 0.
[2022-03-09 00:14:42,185] ERROR org.apache.kafka.common.errors.InvalidReplicationFactorException: Replication factor: 1 larger than available brokers: 0.

原因：
访问地址不正确
解决办法：
查看server.properties中的zookeeper.connect=a:2181,b:2181,c:2181看后面有没有/kafka，以前版本是有/kafka的，所以创建topic就需要加上

kafka-topics.sh --zookeeper localhost:2181/kafka --create --topic topic-demo --partitions 1 --replication-factor 1

如果没有/kafka，则：

kafka-topics.sh --zookeeper localhost:2181 --create --topic topic-demo --partitions 1 --replication-factor 1

问题4

消费报错
生产：
kafka-console-producer.sh --broker-list localhost:9092 --topic topic-demo
消费：
kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topic-demo --from-beginning

[2022-03-09 00:42:40,715] WARN [Producer clientId=console-producer] Connection to node -1 (localhost/127.0.0.1:9092) could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

原因：server.properties文件中监听的地址虽然写的是本机ip：192.168.xx.xx,但是生产ip写的localhost，消费也写的localhost，导致监听地址不同
解决办法：
listeners=PLAINTEXT://host:9092中host都统一
总之：监听，创建topic，生产，消费中ip需一致

总结
