Kafka 集群验证

1. Kafka Node01 启动生产端

   /usr/local/kafka/bin/kafka-console-producer.sh --bootstrap-server 127.0.0.1:9092 --topic test01

   • 启动后，在终端随意输入消息内容

2. Kafka Node02/3 节点上查看消息

   /usr/local/kafka/bin/kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092 --from-beginning --topic test01

   /usr/local/kafka/bin/kafka-console-consumer.sh --bootstrap-server 127.0.0.1:9092 --from-beginning --topic test01

   • 执行后如果输出了在生产端输入的消息内容则正常
