  (1)、启动Zookeeper服务
  和Single node – single broker集群的部署一样,这种模式的集群部署也是需要启用Zookeeper。请参见《Kafka分布式集群部署手册(一)》
  (2)、启动Kafka broker服务
  如果需要在单个node上面启动多个brokers,我们需要复制$KAFKA_HOME/config/server.properties文件。如下:

$ cp server.properties server1.properties
$ cp server.properties server2.properties

并最少修改文件 server.properties、server1.properties和 server2.properties里面的以下几个属性:brokerid、port和log.dir。比如:

$ vim server.properties
brokerid = 0
port = 1234
log.dir = /tmp/wyp/kafka_log

$ vim server1.properties
brokerid = 1
port = 1235
log.dir = /tmp/wyp/kafka_log1

$ vim server2.properties
brokerid = 2
port = 1236
log.dir = /tmp/wyp/kafka_log2

不同的配置文件中其中这三个属性的值不要一样,否则会出现问题。在该结点上启动三个broker:

$ bin/kafka-server-start.sh config/server.properties
$ bin/kafka-server-start.sh config/server1.properties
$ bin/kafka-server-start.sh config/server2.properties

  (3)、如何测试?
  创建一个topic

$ bin/kafka-topics.sh --create --zookeeper master:2181,node:2181,node1:2181 \
           --replication-factor 2 --partitions 2 --topic wyp
Created topic "wyp".

  往wyp中发送消息:

$ bin/kafka-console-producer.sh                                 \
  --broker-list localhost:1234,localhost:1235,localhost:1236 --topic wyp

注意--broker-list localhost:1234,localhost:1235,localhost:1236和Single node – single broker集群的--broker-list不同。
  向wyp中拉取消息:

三、Multiple node – multiple broker集群

  Multiple node – multiple broker集群的部署和Single node – multiple broker集群很类似,只不过多个broker在不同的node上面,它的体系结构图如下:

所以关于Multiple node – multiple broker集群的部署我就不再介绍了。(完)
