zookeeper安装

进入目录：/home/work/zookeeper-3.5.2-alpha/conf

创建zoo.cfg

tickTime=2000  
dataDir=/home/work/www/zookeeper/data  
dataLogDir=/home/work/www/zookeeper/logs
initLimit=5
syncLimit=2
clientPort=4180
server.0=127.0.0.1:8880:7770    
server.1=127.0.0.1:8881:7771    
server.2=127.0.0.1:8882:7772

多集群，修改clientPort ,dataDir dataLogDir 

每个目录dataDir 创建myid ，对应值位 server.x
