Kafka常用命令
启动Kafka服务kafka-server-start.sh
./bin/kafka-server-start.sh config/server.properties
Topic操作Kafka-topics.sh
创建Topic
./bin/kafka-topics.sh --create --topic test-topic --partitions 2 --replication-factor 1 --zookeeper localhost:2181
删除Topic
./bin/kafka-topics.sh --delete --topic test-topic --zookeeper localhost:2181
如果要删除topic，需先要在配置里添加delete.topic.enable=true
显示当前所有Topic
./bin/kafka-topics.sh --list --zookeeper localhost:2181
显示指定Topic详细信息
./bin/kafka-topics.sh --describe --topic test-topic --zookeeper localhost:2181
重新分配分区
./bin/kafka-topics.sh --zookeeper localhost:2181 -alter --partitions 3 --topic test-topic
控制台接收消息
./bin/kafka-console-consumer.sh --from-beginning --topic test-topic -zookeeper localhost:2181
控制台发送消息
./bin/kafka-console-producer.sh --broker-list localhost:9092 --topic test-topic
显示Consumer的Group、Topic、分区ID、分区对应已经消费的Offset、logSize大小，Lag以及Owner等信息
./bin/kafka-consumer-offset-checker.sh --zookeeper localhost:2181 --topic test-topic --group xb_id --broker-info
验证日志索引是否正确，或者想从log文件中直接答应消息
./kafka-run-class.sh kafka.tools.DumpLogSegments
./kafka-run-class.sh kafka.tools.DumpLogSegments /usr/local/kafka/logs/xb_topic-0/0000000000000000000033.log
./kafka-run-class.sh kafka.tools.DumpLogSegments --files /usr/local/kafka/logs/xb_topic-0/0000000000000000000033.log --print--data-log
导出Zookeer中Group相关的偏移量
有时候我们需要导出某个Consumer group各个分区的偏移量
./kafka-run-class.sh kafka.tools.ExportZKOffsets
./kafka-run-class.sh kafka.tools.ExportZKOffsets --group xb_id --zkconnect c13-138:2181,c13-139:2181,c13-141:2181 --output-file ~/offset
vim ~/offset
