Kafka常用命令行总结

以下是kafka常用命令行总结：




1.查看topic的详细信息

./kafka-topics.sh -zookeeper 127.0.0.1:2181 -describe -topic testKJ1

查看所有topic

./kafka-topics.sh --list --zookeeper 127.0.0.1:2181

2.为topic增加副本

./kafka-reassign-partitions.sh -zookeeper 127.0.0.1:2181 -reassignment-json-file json/partitions-to-move.json -execute

3、创建topic

./kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic testKJ1

4、为topic增加partition.

/bin/kafka-topics.sh –zookeeper 127.0.0.1:2181 –alter –partitions 20 –topic testKJ1

5、kafka生产者客户端命令

./kafka-console-producer.sh --broker-list localhost:9092 --topic testKJ1

6、kafka消费者客户端命令

./kafka-console-consumer.sh -zookeeper localhost:2181 --from-beginning --topic testKJ1

7、kafka服务启动

./kafka-server-start.sh -daemon ../config/server.properties

8、下线broker

./kafka-run-class.sh kafka.admin.ShutdownBroker --zookeeper 127.0.0.1:2181 --broker #brokerId# --num.retries 3 --retry.interval.ms 60shutdown broker

9、删除topic

./kafka-run-class.sh kafka.admin.DeleteTopicCommand --topic testKJ1 --zookeeper 127.0.0.1:2181./kafka-topics.sh --zookeeper localhost:2181 --delete --topic testKJ1

10、查看consumer组内消费的offset./kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --zookeeper localhost:2181 --group test --topic testKJ1
