1、查看tocpic

./kafka-topics.sh --bootstrap-server localhost:9092 --list

2、创建一个topic

./kafka-topics.sh --bootstrap-server localhost:9092 --topic first --create --partitions 1

 3、查看主题详细信息

./kafka-topics.sh --bootstrap-server localhost:9092 --topic first --describe

 4、修改topci分区数

只能增加，不能减少

./kafka-topics.sh --bootstrap-server localhost:9092 --topic first --alter --partitions 2

 5、生产者生产数据

/usr/local/kafka_2.12-3.5.1/bin# ./kafka-console-producer.sh --bootstrap-server localhost:9092 --topic first

6、消费者消费数据

--from-beginning：表示从头消费数据，按需添加

/usr/local/kafka_2.12-3.5.1/bin# ./kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic first --from-beginning
