一、 下载 官网地址： http://zookeeper.apache.org/ 下载方法可参考 http://jingyan.baidu.com/article/6181c3e094266d152ef153da.html 不过稍微看得懂英文的也可以找到下载的地方。
二、 安装 我第一次下载的是zookeeper-3.5.0，jdk是1.7的，但是通过bin目录下启动的时候启动失败,报的错误是 java_home is incorrectly set. 通过查找资料提到大致是jdk的版本或者zookeeper的版本不对，后来把jdk换成1.6的，zookeeper换成3.3.6的就好了。
下载完成之后，是新进行配置，配置文件是 ../zookeeper-3.3.6/conf/zoo.cfg。
配置项为：
# 1. The number of milliseconds of each tick tickTime=2000 # 2. The number of ticks that the initial # synchronization phase can take initLimit=10 # 3. The number of ticks that can pass between # sending a request and getting an acknowledgement syncLimit=5 # 4. the directory where the snapshot is stored. # do not use /tmp for storage, /tmp here is just # example sakes. dataDir=D:\\zookeeper-3.3.6\\data #（这里的目录根据实际的来，data目录需要自己手动建） # 5. the directory of logs （日志目录） dataLogDir=D:\\zookeeper-3.3.6\\logs #（这里的目录根据实际的来，dataLogDir目录需要自己手动建） # 6. 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
配置完成之后，进入dos命令行，通过以下步骤启动zookeeper：
C:\Users\John>d: D:\>cd zookeeper-3.3.6 D:\zookeeper-3.3.6>cd bin D:\zookeeper-3.3.6\bin>zkServer.cmd 启动服务 ... .. .
