1.在进入多个broker设置之前,首先启动ZooKeeper服务器/usr/local/zookeeper/bin/zkServer.sh start
2.复制kafka的server.properties文件
cd /usr/local/kafka/config/ cp -a server.properties server1.properties cp -a server.properties server2.properties vim server.properties ---------------------- # The id of the broker. This must be set to a unique integer for each broker. broker.id=0 # The port the socket server listens on listeners=PLAINTEXT://:9092 port=9092 # A comma seperated list of directories under which to store log files log.dirs=/tmp/kafka-logs vim server1.properties ---------------------- # The id of the broker. This must be set to a unique integer for each broker. broker.id=1 # The port the socket server listens on listeners=PLAINTEXT://:9093 port=9093 # A comma seperated list of directories under which to store log files log.dirs=/tmp/kafka-logs-1 vim server2.properties ---------------------- # The id of the broker. This must be set to a unique integer for each broker. broker.id=2 # The port the socket server listens on listeners=PLAINTEXT://:9094 port=9094 # A comma seperated list of directories under which to store log files log.dirs=/tmp/kafka-logs-2
3.启动3个broker
# Broker1 cd /usr/local/kafka bin/kafka-server-start.sh config/server.properties & # Broker2 cd /usr/local/kafka bin/kafka-server-start.sh config/server1.properties & # Broker3 cd /usr/local/kafka bin/kafka-server-start.sh config/server2.properties & # jps 8274 Jps 8079 Kafka 8145 Kafka 8210 Kafka 2004 QuorumPeerMain
4.创建topic
(1)为此topic的复制因子值(replication-factor)指定为3个,因为我们有三个不同的broker运行
(2)如果有两个broker,那么分配的复制因子值也得是2个
cd /usr/local/kafka bin/kafka-topics.sh --create --zookeeper localhost:2181 --replication-factor 3 -partitions 1 --topic Three
5.检查哪个broker正在侦听当前创建的主题
cd /usr/local/kafka bin/kafka-topics.sh --describe --zookeeper localhost:2181 --topic Three ------------ Topic: Three PartitionCount:1 ReplicationFactor:3 Configs: # 分区摘要信息,topic名,分区数量,复制因子 Topic: Three Partition: 0 Leader: 0 Replicas: 0,1,2 Isr: 0,1,2 # broker 0是领导者 ------------
6.生产和消费(注意ip和port)
# 生产 /usr/local/kafka/bin/kafka-console-producer.sh --broker-list 10.1.44.188:9092 --topic Three /usr/local/kafka/bin/kafka-console-producer.sh --broker-list 10.1.44.188:9093 --topic Three /usr/local/kafka/bin/kafka-console-producer.sh --broker-list 10.1.44.188:9094 --topic Three # 消费 /usr/local/kafka/bin/kafka-console-consumer.sh --zookeeper 10.1.44.188:2181 --topic Three --from-beginning jps 2290 ConsoleConsumer 1974 Kafka 1946 QuorumPeerMain 2042 Kafka 2107 Kafka 2460 Jps 2364 ConsoleProducer 2414 ConsoleProducer 2239 ConsoleProducer
