bin/flume-ng agent --conf conf --conf-file conf/example.conf --name a1 -Dflume.root.logger=INFO,console

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
