1.将安装包解压到指定目录：E:\zookeeper-3.5.4-beta 2.进入zooKeeper的配置文件目录E:\zookeeper-3.5.4-beta\conf，修改zoo_sample.cfg 文件名为 zoo.cfg 3.编辑zoo.cfg文件，修改zooKeeper数据和日志储存位置，具体配置如下：
# 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=E:\data\zookeeper\data dataLogDir=E:\data\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进入到bin目录，双击执行zkServer.cmd 运行cmd输入jps -l -v命令可以看到QuorumPeerMain的进程，这是ZooKeeper的进程,zookeeper启动成功！ 参考文章：https://segmentfault.com/a/1190000014642400
