1. 第一步：单机搭建

单机搭建：
安装完后，默认自动安装对应版本zookeeper

brew install kafka

2.第二步：修改配置文件:

配置3个Kafka
第一个（使用默认配置）

vi /opt/homebrew/etc/kafka/server.properties

第二个

cp /opt/homebrew/etc/kafka/server.properties /opt/homebrew/etc/kafka/server-1.properties

第三个

cp /opt/homebrew/etc/kafka/server.properties /opt/homebrew/etc/kafka/server-2.properties

第二个和第三个修改配置文件
vi /opt/homebrew/etc/kafka/server-1.properties

    broker.id=1 
    listeners=PLAINTEXT://:9093 
    log.dir=/tmp/kafka-logs-1

vi /opt/homebrew/etc/kafka/server-1.properties

    broker.id=2 
    listeners=PLAINTEXT://:9094 
    log.dir=/tmp/kafka-logs-2

3.第三步：查看启动服务位置

brew list kafka

4.第四步：服务启动/关闭

启动kafka之前必须启动zookeeper，上面已查出👆（步骤3）。

先启动zookeeper

/opt/homebrew/Cellar/kafka/3.3.1_1/bin/zookeeper-server-start /opt/homebrew/etc/kafka/zookeeper.properties &

再启动kafka

/opt/homebrew/Cellar/kafka/3.3.1_1/bin/kafka-server-start /opt/homebrew/etc/kafka/server.properties &

/opt/homebrew/Cellar/kafka/3.3.1_1/bin/kafka-server-start /opt/homebrew/etc/kafka/server-1.properties &

/opt/homebrew/Cellar/kafka/3.3.1_1/bin/kafka-server-start /opt/homebrew/etc/kafka/server-2.properties &

关闭kafka

/opt/homebrew/Cellar/kafka/3.3.1_1bin/kafka-server-stop

关闭zookeeper

/opt/homebrew/Cellar/kafka/3.3.1_1/bin/zookeeper-server-stop

5.最后：查看启动

查看端口命令
lsof -i :9092

根据进程名查看进程信息
ps aux | grep zookeeper
