问题

kafka执行生产者和消费者命令报错
[root@hadoop89 bin]# kafka-console-producer.sh --broker-list 192.168.159.89:6668 --topic article_topic_1

[2021-06-15 11:01:24,411] WARN [Producer clientId=console-producer] Connection to node -1 could not be established. Broker may not be available. (org.apache.kafka.clients.NetworkClient)

原因

查看kafka的配置文件
cd $KAFKA_HOME/conf
vi server.properties
在这里插入图片描述
端口不是9092 是6667

解决办法

执行生产者消费者命令时把端口改为6667

启动生产者
 kafka-console-producer.sh --broker-list 192.168.159.89:6667 --topic article_topic_1
启动消费者
kafka-console-consumer.sh --bootstrap-server 192.168.159.89:6667 --topic  topic_test1 --from-beginning
