第一次尝试自己在Windows上搭建zk的集群，是在搭建单机zk的基础上操作的。
单机时的zoo.cfg文件如下所示，可正常启动
# 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:\Software\zookeeper\zk_data\server1 # 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

此处并非是正常启动，DataDir的值其实为：D:Softwarezookeeperzk_dataserver1，并非期望的目录。
而对于D:Softwarezookeeperzk_dataserver1而言，"D:"相当于切换盘符，如果命令是在C盘执行，则切换到了D盘根目录，如果本身就在D盘执行，则就在命令所在目录，而“Softwarezookeeperzk_dataserver1”不是以“C:\\”“D:\\”等开头的，故认为是相对路径，所以导致设置的目录为“D:\Software\zookeeper\zookeeper-3.4.10-1\bin\Softwarezookeeperzk_dataserver1”
====================================
复制三个节点，增加对应的集群配置
server.1=localhost:2887:3887 server.2=localhost:2888:3888 server.3=localhost:2889:3889
启动
果然报错了……
去掉server1=local...server2...server3...又可以正常启动，仔细检查了那三行配置也没有多余的空格……为此还在sublime中配置了
"draw_white_space": "all"
百思不得其解，突然想起来log文件里应该会有额外的信息吧……
果不其然

快照日志、事务日志根据以下路径是可以正常存储的
dataDir=D:\Software\zookeeper\zk_data\server1 集群查找myid文件就gg了……是把"\"当做是转义符处理，所以路径错误，找不到myid文件从而启动失败，修改该路径后重新启动一切正常

Ps：zookeeper日志修改需改动log4j.properties的zookeeper.root.logger和zkEnv.cmd中的ZOO_LOG4J_PROP，默认是CONSOLE，我都改成了ROLLINGFILE了
log路径需要修改zkEnv.cmd中的ZOO_LOG_DIR。
log4j.properties中的zookeeper.log.dir=. 表示命令所在的路径 // todo 初步估计zkEnv.cmd中不修改，此处改为绝对路径应该也是可以的，明天验证
验证：zkEnv.cmd中的配置是必须修改的，只修改log4j.properties是不生效的
