Install Kafka on OSX via Homebrew

install-kafka.txt

$> brew cask install java

$> brew install kafka

$> vim ~/bin/kafka
# ~/bin/kafka
#!/bin/bash

zkServer start
kafka-server-start.sh /usr/local/etc/kafka/server.properties

$> chmod +x ~/bin/kafka

If you want to use kraft instead of zookeeper, just replace the default server.properties with the default kraft server.properties.

You can use /usr/local/ instead of $(brew --prefix) if you prefer.

brew install kafka

mv $(brew --prefix)/etc/kafka/kraft/server.properties $(brew --prefix)/etc/kafka/server.properties
kafka-storage format -t $(kafka-storage random-uuid) -c $(brew --prefix)/etc/kafka/server.properties

Then the zookeeper command is not necessary:

brew services start kafka
brew services info kafka
brew services stop kafka

@spartiv -- the info is for showing the status

After installing java (via kafka) I told OSX to use the java that I installed: (not sure if this is necessary)

sudo ln -sfn $(brew --prefix)/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
