mac OSX中安装启动zookeeper

安装

zookeeper支持brew安装。

查看zookeeper 信息

$ brew info zookeeper

安装zookeeper

$ brew install zookeeper

安装后，在/usr/local/etc/zookeeper/目录下，已经有了缺省的配置文件。

$ ls /usr/local/etc/zookeeper
defaults         log4j.properties zoo.cfg          zoo_sample.cfg

打开配置文件

$ 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

主要配置

      2 tickTime=2000
      5 initLimit=10
      8 syncLimit=5
     12 dataDir=/usr/local/var/run/zookeeper/data
     14 clientPort=2181

启动zookeeper

$ which zkServer
/usr/local/bin/zkServer

$ cd /usr/local/bin
$ ls | grep zk
zkCleanup
zkCli
zkServer

$ zkServer start
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Starting zookeeper ... STARTED

连接ZooKeeper服务器

ZooKeeper命令行界面（CLI）用于与ZooKeeper集合进行交互以进行开发。它有助于调试和解决不同的选项。使用如下命令：

$ zkCli
Connecting to localhost:2181
Welcome to ZooKeeper!
JLine support is enabled

WATCHER::

WatchedEvent state:SyncConnected type:None path:null
[zk: localhost:2181(CONNECTED) 0]

一旦客户端启动，就可以使用命令与zookeeper服务器进行交互了。
最后使用 Ctrl + c即可退出zkCli。

停止zookeeper服务器

$ zkServer stop
ZooKeeper JMX enabled by default
Using config: /usr/local/etc/zookeeper/zoo.cfg
Stopping zookeeper ... STOPPED
