kafka集群安装

前期准备:zookeeper集群安装：
zookeeper集群安装点击这里

集群安装
1、解压
2、修改server.properties
broker.id=1
zookeeper.connect=hadoop-master:2181,hadoop-master:2181,hadoop-master: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 –zookeepeprr weekend05:2181 –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 weekend:9092 –topic order

7、用一个comsumer从某一个topic中读取信息
bin/kafka-console-consumer.sh –zookeeper weekend05:2181 –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 weekend05:2181 –topic order
