直接安装：brew install kafka

查看kafka版本：
find / -name \*kafka_\* | head -1 | grep -o '\kafka[^\n]*'

==> zookeeper
To have launchd start zookeeper now and restart at login:
  brew services start zookeeper
Or, if you don't want/need a background service you can just run:
  zkServer start
==> kafka
To have launchd start kafka now and restart at login:
  brew services start kafka
Or, if you don't want/need a background service you can just run:
  zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties & kafka-server-start /usr/local/etc/kafka/server.properties

1.采用homebrew的方式

终端执行命令：brew install kafka

2.修改Kafka服务配置文件server.properties

执行命令: vi /usr/local/etc/kafka/server.properties

解除注释:listeners=PLAINTEXT://localhost:9092(如无该内容则增加，ip地址需要注意以后可能也需要外部访问进行更改)

3.启动zookeeper 服务

执行命令:zookeeper-server-start /usr/local/etc/kafka/zookeeper.properties &

4.启动Kafka服务

执行命令:kafka-server-start /usr/local/etc/kafka/server.properties &

5.创建topic

执行命令(新开终端)：kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic hello

查看已有主题list: kafka-topics --list --zookeeper localhost:2181

6.创建生产者(输入内容生产消息由消费者获取)

执行命令(新开终端):kafka-console-producer --topic hello --broker-list localhost:9092

7.创建消费者(读取生产者生产的消息内容)

执行命令(新开终端):kafka-console-consumer --bootstrap-server localhost:9092 -topic hello

注意：启动kafka和创建topic、生产者、消费者分别启动独自的窗口进行编辑
