zookeeper是一个为分布式应用所设计的分布式的、开源的调度服务，它主要用来解决分布式应用中经常遇到的一些数据管理问题，简化分布式应用，协调及其管理的难度，提高性能的分布式服务。
本章的目的：如何安装zookeeper（在win7环境下），zookeeper下载https://mirrors.cnnic.cn/apache/zookeeper/。这里下载的版本是3.4.8.
zoomkeeper本身是可以单节点模式安装运行，不过一般为了确保zookeeper的稳定性和可用性，都会采用分布式部署，也进而保证了分布式应用的可靠性。它在分布式zookepper集群中，会基于选举算法来实现一个leader，多个follower。

- 单节点安装及配置：
1）下载zookeeper-3.4.8.tar.gz,并解压到目录：D:\Work\zookeeper\zookeeper-3.4.8下
2）进入conf目录下把zoo_sample.cfg文件重名为：zoo.cfg，并修改配置为如下:
# 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:\\Work\\zookeeper\\data # log config dataLogDir=D:\\Work\\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
3）启动zookeeper服务：
进入目录：D:\Work\zookeeper\zookeeper-3.4.8\bin，执行zkServer.cmd，这样就启动了zookeeper服务了。

4）启动客户端
进入目录：D:\Work\zookeeper\zookeeper-3.4.8\bin，执行zkCli.cmd -server 127.0.0.1:2181，这样就启动了zookeeper服务了。

这样就安装完成了单节点zookeeper服务。
