版本查看

kafka-topics.sh --version

查看kafka端口号

ps -ef | grep kafka/config/server.properties
sudo netstat -nlpt | grep 7745

查看zookeeper端口号

ps -ef | grep org.apache.zookeeper.server.quorum.QuorumPeerMain
sudo netstat -nlpt | grep 4683

topic命令

查询topic列表
kafka-topics.sh --list --zookeeper isxcode:2181
创建topic
kafka-topics.sh --create --zookeeper isxcode:2181 --topic ispong-topic --replication-factor 1 --partitions 1
查询topic信息
kafka-topics.sh --describe --zookeeper isxcode:2181 --topic ispong-topic
删除topic
kafka-topics.sh --delete --zookeeper isxcode:2181 --topic ispong-topic

如果无法删除,则需要在zk中强行删除

# zookeeper-shell.sh isxcode:2181
ls /brokers/topics
deleteall /brokers/topics/ispong_kafka

生产者命令

kafka-console-producer.sh --topic ispong-topic --broker-list isxcode:9092

消费者命令

kafka-console-consumer.sh --bootstrap-server 192.168.115.104:30120 --topic ispong-topic --from-beginning --property print.key=true

group.id查看

cat /opt/kafka/config/consumer.properties | grep group.id=
