==> 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

查看zookeeper 信息


brew info zookeeper

brew nstall 完成之后对应配置如下


/usr/local/etc/zookeeper
chengkejundeMacBook-Pro:zookeeper c.kj$ ls
defaults        log4j.properties    zoo.cfg         zoo_sample.cfg
chengkejundeMacBook-Pro:zookeeper c.kj$

修改 zoo.cfg 搭建集群修改这些配置因为只需要搭建一个伪集群所以没有修改其中参数，感兴趣的可以自己搜索一些教程～


# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just
# example sakes.
dataDir=/usr/local/Cellar/zookeeper/data
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the
# administrator guide before turning on autopurge.

为了能够在任意目录启动zookeeper集群，我们需要配置环境变量.

ps:你也可以不配，这不是搭建集群的必要操作，只不过如果你不配置环境变量，那么每次启动zookeeper需要到安装文件的 bin 目录下去启动。

配置如下


chengkejundeMacBook-Pro:data c.kj$ open -e ~/.bash_profile
chengkejundeMacBook-Pro:data c.kj$ cat ~/.bash_profile
export M3_HOME=/usr/local/mvn/apache-maven-3.3.9
export GRADLE_HOME=/usr/local/Cellar/gradle/5.2.1
export SCALA_HOME=/usr/local/Cellar/scala/2.12.8
export ZK_HOME=/usr/local/Cellar/zookeeper/3.4.13
export PATH=$M3_HOME/bin:$PATH:$GRADLE_HOME/bin:$SCALA_HOME/bin:$ZK_HOME/binchengkejundeMacBook-Pro:data c.kj$
chengkejundeMacBook-Pro:data c.kj$
chengkejundeMacBook-Pro:data c.kj$ source ~/.bash_profile

启动命令：
zkServer start

停止命令：
zkServer stop

重启命令：
zkServer restart

查看集群节点状态：
zkServer status


chengkejundeMacBook-Pro:~ c.kj$ zkServer start
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Starting zookeeper ... already running as process 49422.
chengkejundeMacBook-Pro:~ c.kj$ zkServer status
ZooKeeper JMX enabled by default

chengkejundeMacBook-Pro:~ c.kj$
