1、下载

　　下载地址：http://www.apache.org/dyn/closer.cgi/zookeeper/ ，下载解压到D:\tools 如下图所示：

2、启动

　　进入bin文件夹下，如下图：

3、运行(windows环境)

　　双击zkServer.cmd，发现闪退

4、问题解决

　　打开zkServer.cmd进行编辑，在尾部加pause,如下图：

保存，再次双击，发现找不到zoo.cfg文件，如下图：

进入conf文件夹下，将zoo_sample.cfg文件复制一份修改为zoo.cfg,如下图：

修改zoo.cfg

# 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:/tools/zookeeper-3.4.9/data # 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

　　至此ZooKeeper在Windows操作系统中安装配置完毕，但需要指出的是ZooKeeper是使用java编写的，因此运行ZooKeeper之前必须安装Java环境——配置JDK，且JDK的版本要大于或等于1.6。

5、再次启动

　　双击zkServer.cmd,出现如下界面，则启动成功
