1、修改操作系统的/etc/hosts文件，添加IP与主机名映射：
# vim /etc/hosts #zookeeper cluster server 192.168.1.135 server-zk-01 192.168.1.135 server-zk-02 192.168.1.135 server-zk-03
2、下载安装zookeeper
wget http://mirrors.hust.edu.cn/apache/zookeeper/zookeeper-3.4.8/zookeeper-3.4.8.tar.gz
tar -zxvf zookeeper-3.4.8.tar.gz cd ./zookeeper-3.4.8 cp -R zookeeper-3.4.8 zookeeper-node-01 mkdir data mkdir logs 将zookeeper-node-01/conf目录下的zoo_sample.cfg文件拷贝一份，命名为为zoo.cfg cp zoo_sample.cfg zoo.cfg 修改zoo.cfg tickTime=2000 initLimit=10 syncLimit=5 dataDir=/home/leantaot/zookeeper/zookeeper-node-01/data dataLogDir=/home/leantaot/zookeeper/zookeeper-node-01/logs clientPort=2181 server.1=leantaot-zk-01:2881:3881 server.2=leantaot-zk-02:2882:3882 server.3=leantaot-zk-03:2883:3883
3、创建myid文件
4、启动zookeeper
zkServer.sh start zkServer.sh status zkServer.sh stop 连接zookeeper（server-zk-01为/etc/hosts配置的hostname） zkCli.sh -server server-zk-01:2181
5、dubbo配置方式
dubbo.registry.address=zookeeper://192.168.1.135:2181?backup=192.168.1.135:2182,192.168.1.135:2183
