解压，配置文件server.properties，地址，存储位置，分区等等

先启动zookeeper

查看主题

kafka-topics.sh --zookeeper chen133:2181 --list

创建主题

kafka-topics.sh --create --zookeeper 192.168.153.133:2181 --topic mydemo --partitions 1 --replication-factor 1

创建生产者

kafka-console-producer.sh --topic mydemo --broker-list chen133:9092

创建消费者

kafka-console-consumer.sh --bootstrap-server chen133:9092 --topic mydemo --from-beginning

查看消息数量

kafka-run-class.sh kafka.tools.GetOffsetShell --broker-list chen133:9092 --topic mydemo -time  -1 --offsets 1

查看主题具体情况

kafka-topics.sh --zookeeper chen133:2181 --describe --topic mydemo

查看所有主题

kafka-topics.sh --zookeeper chen133:2181 --describe

进入zookeeper

zkCli.sh -server chen133:2181

[zk: chen133:2181(CONNECTED) 4] ls /brokers

[ids, topics, seqid]

[zk: chen133:2181(CONNECTED) 5] ls /brokers/topics

[mydemo2, __consumer_offsets, mydemo]

[zk: chen133:2181(CONNECTED) 8] ls /brokers/topics/mydemo2/partitions

[0, 1, 2]

感觉Kafka原理好难理解谁能教教我
