记录一下在 Mac 上安装和测试 kafka 的步骤。
MacOS 上可以方便的使用 brew 进行安装。
brew很慢，可以换清华源 juejin.cn/post/684490…
安装
如果还没有安装Java, 可以先安装Java:
1、安装最新版本的java 13
brew cask install java
2、安装jdk8
参考:stackoverflow.com/questions/5…
brew cask install adoptopenjdk/openjdk/adoptopenjdk8
# 或者
brew cask install homebrew/cask-versions/adoptopenjdk8
3、在Mac中安装不同版本Java时的切换使用
参考：code000two.github.io/2019/01/17/…
➜ ~ cat ~/.zshrc
# JAVA_HOME SWITCH
# default java13
export JAVA_HOME=$JAVA_13_HOME
# set JDK 8
export JAVA_8_HOME=$(/usr/libexec/java_home -v 1.8)
# set JDK 13
export JAVA_13_HOME=$(/usr/libexec/java_home -v 13.0)
# switch
alias jdk8='export JAVA_HOME=$JAVA_8_HOME'
alias jdk13='export JAVA_HOME=$JAVA_13_HOME'
4、安装kafka和zookeeper
➜ ~ brew install kafka

==> Installing kafka dependency: zookeeper

==> Caveats
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

brew services start kafka
Or, if you don't want/need a background service you can just run:

5、修改配置
修改 /usr/local/etc/kafka/server.properties, 找到 listeners=PLAINTEXT://:9092 那一行，把注释取消掉。 然后修改为:
############################# Socket Server Settings #############################
# The address the socket server listens on. It will get the value returned from
# java.net.InetAddress.getCanonicalHostName() if not configured.
# FORMAT:
# listeners = listener_name://host_name:port
# EXAMPLE:
# listeners = PLAINTEXT://your.host.name:9092
listeners=PLAINTEXT://localhost:9092
启动
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
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、以服务的方式启动
brew services start zookeeper
brew services start kafka
2、或者临时启动
$ zkServer start
$ kafka-server-start /usr/local/etc/kafka/server.properties
创建Topic
➜ ~ kafka-topics --create --zookeeper localhost:2181 --replication-factor 1 --partitions 1 --topic test
Created topic test.
➜ ~
产生消息
➜ ~ kafka-console-producer --broker-list localhost:9092 --topic test
>HELLO Kafka
>
消费消息
简单方式:
kafka-console-consumer --bootstrap-server localhost:9092 --topic test --from-beginning
如果使用消费组:
kafka-console-consumer --bootstrap-server localhost:9092 --topic test --group test-consumer1 --from-beginning
