Win7 Zookeeper的下载与安装

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 ticktickTime=2000# 2. The number of ticks that the initial # synchronization phase can takeinitLimit=10# 3. The number of ticks that can pass between # sending a request and getting an acknowledgementsyncLimit=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 connectclientPort=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-3.3.6D:\zookeeper-3.3.6>cd binD:\zookeeper-3.3.6\bin>zkServer.cmd启动服务......
