1：linux单机安装使用
软件创建 data 文件夹，进入 conf 目录 ，把 zoo_sample.cfg 改名为 zoo.cfg，默认2181端口
mkdir data
cd conf
mv zoo_sample.cfg zoo.cfg
常用命令，进入 bin 目录
#启动
./zkServer.sh start
#查看状态
./zkServer.sh status
2、zookeeper集群搭建
复制3份zookeeper，修改配置文件zoo.cfg如下，dataDir，dataLogDir，clientPort做相应的调整。
(版本：zookeeper-3.4.8-1)
# 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=E:\zookeeper\zk_2\data
dataLogDir=E:\zookeeper\zk_2\logs
# the port at which the clients will connect
clientPort=2182
server.1=localhost:2287:3387
server.2=localhost:2288:3388
server.3=localhost:2289:3389
data目录下，新建myid文件，内容分别为1，2，3
启动3台zookeeper，zkServer.cmd。集群就配置完成！
