Kafka常用命令
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
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 60
shutdown 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
