1、什么时Zookeeper
ZooKeeper：分布式服务框架 Zookeeper -- 管理分布式环境中的数据。
2、安装
1》官网下载压缩包并解压zookeeper-3.4.14.zip
2》在zookeeper-3.4.14的Home目录新建data、log文件夹
3》进入conf目录，复制其中的zoo_sample.cfg文件到同级目录，重命名为zoo.cfg（Zookeeper 在启动时会找这个文件作为默认配置文件）。修改其中的dataDir、dataLogDir
...
# example sakes.
dataDir=F:\ebook\Dubbo\zookeeper-3.4.14\data
dataLogDir=F:\ebook\Dubbo\zookeeper-3.4.14\log
# the port at which the clients will connect
...
3、启动测试
