Apache官方最新版本为：3.4.8 下载地址： http://mirrors.cnnic.cn/apache/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz 环境变量：ZOOKEEPER_HOME  变量值 E:\zookeeper\zookeeper-3.5.2

 安装

      解压到指定目录下     D:\soft\zookeeper-3.4.8       修改zoo_sample.cfg 文件名(D:\soft\zookeeper-3.4.8\conf) 为 zoo.cfg       主要修改一下日志位置，具体配置文件如下： # 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=D:\\zookeeper\\data dataLogDir=D:\\zookeeper\\log # 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 配置文件简单解析 1、tickTime：这个时间是作为 Zookeeper 服务器之间或客户端与服务器之间维持心跳的时间间隔，也就是每个 tickTime 时间就会发送一个心跳。 2、dataDir：顾名思义就是 Zookeeper 保存数据的目录，默认情况下，Zookeeper 将写数据的日志文件也保存在这个目录里。 3、dataLogDir：顾名思义就是 Zookeeper 保存日志文件的目录 4、clientPort：这个端口就是客户端连接 Zookeeper 服务器的端口，Zookeeper 会监听这个端口，接受客户端的访问请求。

      启动

进入到bin目录，并且启动zkServer.cmd，这个脚本中会启动一个java进程
