ZooKeeper 集群环境搭建 （本机3个节点）
是一个简单的分布式同步数据库（或者是小文件系统）
--------------------------------------------------------
1、建立目录
server1
server1/dataDir
server1/dataLogDir
server1/logs
server1/zookeeper3.4.6
server2
server2/dataDir
server2/dataLogDir
server2/logs
server2/zookeeper3.4.6
server3
server3/dataDir
server3/dataLogDir
server3/logs
server3/zookeeper3.4.6
-------------------------------------------------------
2、myid
server1/dataDir/myid
1
server2/dataDir/myid
2
server3/dataDir/myid
3
--------------------------------------------------------
3、zoo.cfg
server1/dataDir/zookeeper3.4.6/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:/Tools/zookeeper3.4.6/server1/dataDir
dataLogDir=D:/Tools/zookeeper3.4.6/server1/dataLogDir
clientPort=2181
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
server2/dataDir/zookeeper3.4.6/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:/Tools/zookeeper3.4.6/server2/dataDir
dataLogDir=D:/Tools/zookeeper3.4.6/server2/dataLogDir
clientPort=2182
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
server3/dataDir/zookeeper3.4.6/conf/zoo.cfg
tickTime=2000
initLimit=5
syncLimit=2
dataDir=D:/Tools/zookeeper3.4.6/server3/dataDir
dataLogDir=D:/Tools/zookeeper3.4.6/server3/dataLogDir
clientPort=2183
server.1=localhost:2887:3887
server.2=localhost:2888:3888
server.3=localhost:2889:3889
--------------------------------------------------------
3、log4j.properties
server1/dataDir/zookeeper3.4.6/conf/log4j.properties
# Define some default values that can be overridden by system properties
zookeeper.root.logger=INFO, CONSOLE
zookeeper.console.threshold=INFO

zookeeper.log.file=zookeeper.log
zookeeper.log.threshold=DEBUG
zookeeper.tracelog.dir=D:/Tools/zookeeper3.4.6/server1/logs
zookeeper.tracelog.file=zookeeper_trace.log

log4j.appender.TRACEFILE=org.apache.log4j.FileAppender
log4j.appender.TRACEFILE.Threshold=TRACE
log4j.appender.TRACEFILE.File=${zookeeper.tracelog.dir}/${zookeeper.tracelog.file}
log4j.appender.TRACEFILE.layout=org.apache.log4j.PatternLayout
### Notice we are including log4j's NDC here (%x)
log4j.appender.TRACEFILE.layout.ConversionPattern=%d{ISO8601} [myid:%X{myid}] - %-5p [%t:%C{1}@%L][%x] - %m%n
