下载
ZK官网
解压
tar -xvf zookeeper-3.4.10.tar.gz
启动zk

mv zookeeper-3.4.12 zk
cd zk/
cd conf/
cp zoo_sample.cfg zoo.cfg
cd ../bin
sh zkServer.sh start

简单测试

./zkCli.sh create /han_node 192.168.1.1 #创建节点
./zkCli.sh ls / #查看目录下的所有节点
./zkCli.sh get /han_node #获取当前节点的值

zkCli的指令集

ZooKeeper -server host:port cmd args
    stat path [watch]
    set path data [version]
    ls path [watch]
    delquota [-n|-b] path
    ls2 path [watch]
    setAcl path acl
    setquota -n|-b val path
    history 
    redo cmdno
    printwatches on|off
    delete path [version]
    sync path
    listquota path
    rmr path
    get path [watch]
    create [-s] [-e] path data acl
    addauth scheme auth
    quit 
    getAcl path
    close 
    connect host:port

集群配置

编辑三台机器的conf/zoo.cfg

server.1=centos01:2888:3888
server.2=centos02:2888:3888
server.3=centos03:2888:3888
maxClientCnxns=60

设置机器id，编辑dataDir=/tmp/zookeeper指定目录下的myid文件，设置id（1~256）

启动服务器
zkServer.sh start
查看服务器状态
zkServer.sh status
输出，集群启动成功
[root@centos02 bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/vagrant/soft/zk/bin/../conf/zoo.cfg
