 ==> Downloading https://homebrew.bintray.com/bottles/zookeeper-3.4.12.high_sierr
###### ################################################################## 100.0%
==> Pouring zookeeper-3.4.12.high_sierra.bottle.tar.gz
==> 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
  1. 安装后，在/usr/local/etc/zookeeper/ 中可查看配置
1
$ ls /usr/local/etc/zookeeper/

  • 安装后，在/usr/local/etc/zookeeper/ 已经有了缺省配置

    1
    $ ls /usr/local/etc/zookeeper/

    • 查看配置文件

      1
      $ less -N /usr/local/etc/zookeeper/zoo.cfg

    • 配置文件如下
