windows搭建zookeeper集群报错之Invalid config, exiting abnormally

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

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……会把"\"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  // todo 明天看源码查一查两者处理方式

dataDir=D:\\Software\\zookeeper\\zk_data\\server1

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

明天正常上班~goodnight

刚刚发邮件给博客园注销了一个不用的账号，后台提供支持服务的tx也是蛮辛苦的~

加油！
