kafka使用命令

kakfa版本：2.13-3.0.0

1、创建一个副本为1，分区数量为3个名为mytopic的topic(下面操作可以一个单点上操作，也就是说可以用elk:9092代替elk01:9092,elk02:9092,elk03:9092)

bin/kafka-topics.sh --create --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --replication-factor 1 --partitions 3 --topic mytopic

Created topic mytopic.

2、查看当前所有的topic

bin/kafka-topics.sh --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --list

mytopic

3、查看名为mytopic的topic属性

bin/kafka-topics.sh --describe --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --topic mytopic

Topic: mytopic	TopicId: CZoXBb6gQLikx8Jzy8IDWg	PartitionCount: 3	ReplicationFactor: 1	Configs: segment.bytes=1073741824
	Topic: mytopic	Partition: 0	Leader: 2	Replicas: 2	Isr: 2
	Topic: mytopic	Partition: 1	Leader: 3	Replicas: 3	Isr: 3
	Topic: mytopic	Partition: 2	Leader: 1	Replicas: 1	Isr: 1

4、在名为mytopic的topic中生产消息（ctrl+c退出）

bin/kafka-console-producer.sh --broker-list elk01:9092,elk02:9092,elk03:9092 --topic mytopic
>my mo  # 这个是输入信息

5、 在名为mytopic的topic中消费消息（ctrl+c退出）

bin/kafka-console-consumer.sh --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --topic mytopic
my mo

 6、从头开始接送消息

bin/kafka-console-consumer.sh --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --topic mytopic --from-beginning

 

 7、删除名为mytopic的topic

bin/kafka-topics.sh --delete --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --topic mytopic  # 删除
bin/kafka-topics.sh --bootstrap-server elk01:9092,elk02:9092,elk03:9092 --list  # 查看
