1.linux安装kafka

源码下载：https://download.csdn.net/download/adam_zs/24829887

参考；http://kafka.apache.org/quickstart
备注：现在安装kafka不需要安装ZooKeeper
常用命令：
cd /usr/local/kafka_2.13-3.0.0/
nohup bin/zookeeper-server-start.sh config/zookeeper.properties & #启动zookeeper
nohup bin/kafka-server-start.sh config/server.properties & #启动kafka
bin/kafka-topics.sh --create --topic quickstart-events --bootstrap-server localhost:9092 --partitions 1 --replication-factor 1 #创建主题名quickstart-events
bin/kafka-console-producer.sh --topic quickstart-events --bootstrap-server localhost:9092 #启动kafka生产者
bin/kafka-console-consumer.sh --topic quickstart-events --from-beginning --bootstrap-server localhost:9092 #启动kafka消费者

2.安装kafka界面工具CMAK

参考：https://www.jianshu.com/p/c3c8f55310f9
备注：需要jdk11版本
常用命令：
cd /usr/local/cmak-3.0.0.5
nohup bin/cmak & #启动cmak

3.spring boot集成kafka

application.yml

spring:
  kafka:
    #生产者
    producer:
      bootstrap-servers: 10.18.xx.xx:9092
      key-serializer: org.apache.kafka.common.serialization.StringSerializer
      value-serializer: org.apache.kafka.common.serialization.StringSerializer
    #消费者
    consumer:
      bootstrap-servers: 10.18.xx.xx:9092
      group-id: foo
      auto-offset-reset: earliest
