修改如下配置信息
config/server-1.properties:
broker.id=1
port=9093
log.dir=/tmp/kafka-logs-1

config/server-2.properties:
broker.id=2
port=9094
log.dir=/tmp/kafka-logs-2

broker.id 是唯一标示，因为在单机运行集群，所以修改下端口地址和日志存放目录

启动这两个broker

> bin/kafka-server-start.sh config/server-2.properties &

建立一个集群的topic
zhaoming@zhaoming:~/install/soft/kafaka/kafka_2.9.2-0.8.1.1$ bin/kafka-topics.sh –create –zookeeper localhost:2181 –replication-factor 3 –partitions 1 –topic replicated-topic
Created topic “replicated-topic”.

查看集群情况
zhaoming@zhaoming:~/install/soft/kafaka/kafka_2.9.2-0.8.1.1$ bin/kafka-topics.sh –describe –zookeeper localhost:2181 –topic replicated-topic
Topic:replicated-topic PartitionCount:1 ReplicationFactor:3 Configs:
Topic: replicated-topic Partition: 0 Leader: 1 Replicas: 1,0,2 Isr: 1,0,2

第一行信息：一个分区，复制因子是3
第二行信息：名字是replicated-topic 分区0 ，多个broker的leader是boker.id为1 的那个broker ， Replicas：复制且被leader管理的broker ，Isr：目前存活且被leader管理的broker

查看下没有做复制的topic
zhaoming@zhaoming:~/install/soft/kafaka/kafka_2.9.2-0.8.1.1$ bin/kafka-topics.sh –describe –zookeeper localhost:2181 –topic test_topic
Topic:test_topic PartitionCount:1 ReplicationFactor:1 Configs:
Topic: test_topic Partition: 0 Leader: 0 Replicas: 0 Isr: 0

一个分区，复制因子是1 leader是boker.id为1的broker，复制且存活的broker都是0
