Mac安装kafka实践排错指南

1. brew && brew cask

brew:是下载项目的源码解压然后./configure && make install,同时会包含相关依存库。并自动配置 好各种环境变量，而且易于卸载。
brew cask:是已经编译好了的应用包(.dmg/.pkg).
仅仅是下载解压，放在统一的目录中(/opt/homebrew-cask/Caskroom)然后再软链到~/Applications/目录下, 省掉了自己去下载、解压、拖拽(安装)等蛋疼的步骤，同样，卸载相当容易与干净。
总的来说:brew是通过源码的方式来安装软件,brew cask是安装GUI图形化程序,比如我们下载的(.dmg/.pkg)

2 安装brew cask

在Mac安装kafka的时候需要安装java8,我们采用brew cask来安装,就需要先安装brew cask,但是有时候会遇到如下问题:

Error: Cask 'brew-cask' is unavailable: '/usr/local/Homebrew/Library/Taps/caskroom/homebrew-cask/Casks/brew-cask.rb' does not exist

此时执行下面的命令可以解决:

brew install brew-cask-completion

3 安装adoptopenjdk8

现在不能直接安装java8

brew install homebrew/cask-versions/java8

会报下面的错误:

Error: Cask 'java8' is unavailable: '/usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask-versions/Casks/java8.rb' does not exist.

所以我们需要安装公开的jdk8

brew cask install adoptopenjdk/openjdk/adoptopenjdk8

如下则安装完成:

MacBook-Pro  ~  brew cask install adoptopenjdk/openjdk/adoptopenjdk8

4 安装kafka

完成上面的准备工作就可以安装kafka了,其中也会安装依赖的zookeeper:

brew install kafka

静待成功.然后就可以愉快的学习(玩耍)了

==> 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
