创建主题:
./kafka-topics.sh –zookeeper localhost:12181 –create –topic lfwer –partitions 10 –replication-factor 2
增加主题分区数
./kafka-topics.sh –zookeeper localhost:12181 –alter –topic lfwer –partitions 10
删除主题
在server.properties中增加设置,默认未开启
delete.topic.enable=true
重启kafka
./kafka-server-stop.sh
./kafka-server-start.sh -daemon ../config/server.properties
执行删除
./kafka-topics.sh –zookeeper localhost:12181 –delete –topic lfwer
生产数据:
./kafka-console-producer.sh –topic lfwer –broker-list localhost:9092
消费数据:
./kafka-console-consumer.sh –topic lfwer –bootstrap-server localhost:9092
查看主题在分区中的偏移量 (time为-1时表示最大值,time为-2时表示最小值)
./kafka-run-class.sh kafka.tools.GetOffsetShell –topic lfwer –time -1 –broker-list localhost:9091 –partitions 0
查看有多少个组
./kafka-consumer-groups.sh –bootstrap-server localhost:9091 –list
查看组消费情况
./kafka-consumer-groups.sh –bootstrap-server localhost:9091 –describe –group my-group
