前言
项目需要，所以，在mac OSX中安装了一下zookeeper。
安装
查看brew info zookeeper
$ brew info zookeeper zookeeper: stable 3.4.12 (bottled), HEAD Centralized server for distributed coordination of services https://zookeeper.apache.org/
安装brew install zookeeper
$ brew install zookeeper ==> 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
安装后，在/usr/local/etc/zookeeper/ 已经有了缺省配置
$ ls /usr/local/etc/zookeeper/
查看缺省配置文件
$ less -N /usr/local/etc/zookeeper/zoo.cfg
缺省内容如下：
$less -N /usr/local/etc/zookeeper/zoo.cfg 1 # The number of milliseconds of each tick 2 tickTime=2000 3 # The number of ticks that the initial 4 # synchronization phase can take 5 initLimit=10 6 # The number of ticks that can pass between 7 # sending a request and getting an acknowledgement 8 syncLimit=5 9 # the directory where the snapshot is stored. 10 # do not use /tmp for storage, /tmp here is just 11 # example sakes. 12 dataDir=/usr/local/var/run/zookeeper/data 13 # the port at which the clients will connect 14 clientPort=2181 15 # the maximum number of client connections. 16 # increase this if you need to handle more clients 17 #maxClientCnxns=60 18 # 19 # Be sure to read the maintenance section of the 20 # administrator guide before turning on autopurge. 21 # 22 # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance 23 # 24 # The number of snapshots to retain in dataDir 25 #autopurge.snapRetainCount=3 26 # Purge task interval in hours 27 # Set to "0" to disable auto purge feature 28 #autopurge.purgeInterval=1
启动服务
执行命令zkServer
$ zkServer ZooKeeper JMX enabled by default Using config: /usr/local/etc/zookeeper/zoo.cfg Usage: ./zkServer.sh {start|start-foreground|stop|restart|status|upgrade|print-cmd} $ zkServer status ZooKeeper JMX enabled by default Using config: /usr/local/etc/zookeeper/zoo.cfg Error contacting service. It is probably not running. $ zkServer start ZooKeeper JMX enabled by default Using config: /usr/local/etc/zookeeper/zoo.cfg Starting zookeeper ... STARTED
查看zookeeper运行及状态
安装后，可以看到zookeeper提供了zkCli等工具进行.
