安装kafka
集群安装
1、解压
2、修改server.properties
broker.id=1
zookeeper.connect=zjgm01:2181,zjgm02:2181,zjgm03:2181
3、将zookeeper集群启动
4、在每一台节点上启动broker
bin/kafka-server-start.sh config/server.properties
5、在kafka集群中创建一个topic
bin/kafka-topics.sh --create --zookeeper zjgm01:2181 --replication-factor 3 --partitions 1 --topic order
6、用一个producer向某一个topic中写入消息
bin/kafka-console-producer.sh --broker-list zjgm01:9092 --topic order
7、用一个comsumer从某一个topic中读取信息
bin/kafka-console-consumer.sh --zookeeper zjgm01:2181 --from-beginning --topic order
8、查看一个topic的分区及副本状态信息
bin/kafka-topics.sh --describe --zookeeper zjgm01:2181 --topic order
9.查看topic
bin/kafka-topics.sh --list --zookeeper zjgm01:2181
10.删除topic
server.properties 设置 delete.topic.enable=true
bin/kafka-topics.sh --delete --zookeeper zjgm01:2181 --topic wordcount
