telnet localhost 44444
三个节点都开启kafka服务
bin/kafka-server-start.sh config/server.properties &
启动之后输入exit，再重新登录
exit
创建topic
bin/kafka-topics.sh --zookeeper server1:2181,server2:21821,server3:2181 --create --replication-factor 3 --partitions 1 --topic mytopic
启动消费者
bin/kafka-console-consumer.sh --zookeeper server1:2181,server2:2181,server3:2181 --from-beginning --topic mytopic
随便在telnet的窗口输入点什么，观察消费者窗口
补充命令查看所有topic
bin/kafka-topics.sh --zookeeper server3:2181 --list
删除topic
bin/kafka-topics.sh --zookeeper server1:2181 --delete --topic first
启动生产者
bin/kafka-console-producer.sh --broker-list server1:9092 --topic first
查看某个topic详情
bin/kafka-topics.sh --zookeeper hadoop102:2181 --describe --topic first
停止服务
bin/kafka-server-stop.sh stop
