/usr/local/kafka/kafka_2.11-0.8.2.1

修改每台服务器的config/server.properties

broker.id： 唯一，填数字，本文中分别为132/133/134

host.name：唯一，填服务器IP，之前配置时，把中间的'.'给忘写了，导致kafka集群形同虚设（基本只有leader机器在起作用），以及一系列莫名其妙的问题，伤啊

zookeeper.connect=192.168.40.134:2181,192.168.40.132:2181,192.168.40.133:2181

启动zookeeper(standalone模式):zkServer.sh stop

> bin/zookeeper-server-stop.sh config/zookeeper.properties &

启动kafka：

> bin/kafka-server-start.sh config/server.properties &

创建消息主题

bin/kafka-topics.sh --create \

--replication-factor 3 \

--partition 3 \

--topic user-behavior-topic \

--zookeeper 192.168.1.1:2181,192.168.1.2:2181,192.168.1.3:2181

查看topic的详细信息

bin/kafka-topics.sh --describe --zookeeper master:2181

生产者,输入数据

bin/kafka-console-producer.sh --broker-list master:9092 --topic user-behavior-topic

消费者,消费数据,这个和producer不是在一个窗口

bin/kafka-console-consumer.sh --zookeeper master:2181 --topic user-behavior-topic --from-beginning

bin/kafka-preferred-replica-election.sh --zookeeper 192.168.175.127:2181,192.168.75.128,192.168.75.129:2181 --path-to-json-file preferred-click.json
