ZooKeeper是Hadoop的正式子项目，它是一个针对大型分布式系统的可靠协调系统，提供的功能包括：配置维护、名字服务、分布式同步、组服务等。ZooKeeper的目标就是封装好复杂易出错的关键服务，将简单易用的接口和性能高效、功能稳定的系统提供给用户
下载

解压
进入${zookeeper}/config
重新命名 zoo_sample.cfg --> zoo.cfg
修改dataDir=/tmp/zookeeper --> dataDir=F:\\taobao\\zookeeper-3.3.6\\data
新增 dataLogDir=F:\\taobao\\zookeeper-3.3.6\\logs
其余的不用改
Cmd命令行进入到${zookeeper}/bin
F:\taobao\zookeeper-3.3.6\bin>zkServer.cmd
看到控制打印出一串信息
F:\taobao\zookeeper-3.3.6\bin>zkCli.cmd -server 127.0.0.1:2181

。。。。。。
总之没有错误信息 表示成功了。
不关闭当前窗口，另外打开一个cmd命令行
进入${zookeeper}/bin
F:\taobao\zookeeper-3.3.6\bin>zkCli.cmd -server 127.0.0.1:2181
控制台没有保存表示成功
。。。。

WATCHER::

ls

这样zookeeper就按照好了。
