1、安装（Linux，集群，3台机器）

  1. java环境，安装jdk，至少需要1.6版本
  2. 下载zookeeper，进入zookeeper/conf目录，拷贝zoo_sample.cfg，重命名为zoo.cfg，配置如下
# 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/zookeeper-3.4.6/data
dataLogDir=/usr/local/zookeeper-3.4.6/dataLog
# 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.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1
server.1=192.168.236.128:2888:3888
server.3=192.168.236.130:2888:3888
server.5=192.168.236.137:2888:3888

然后在dataDir对应的目录中，新建myid文件填入ID值，对应如下图server后面的数字

完了之后通过bin目录下面的zkServer.sh脚本可以开启和关闭服务，通过ps命令可以验证zk开启成功，通过bin目录下面的zkCli.sh脚本可以开启zk的命令终端，然后使用zk命令操作

Java API操作
