1 Zookeeper注册中心的搭建（windows单机）

1. 下载zookeeper压缩包并解压到 D:\zookeeper\apache-zookeeper-3.5.5-bin，官网地址：http://www.apache.org/dyn/closer.cgi/zookeeper/
2. 进入conf目录将 zoo_sample.cfg 更名为 zoo.cfg。
   默认配置以下：
   

   # The number of milliseconds of each tick
   tickTime=2000
   # The number of ticks that the initial 
   # synchronization phase can take
   initLimit=5
   # The number of ticks that can pass between 
   # sending a request and getting an acknowledgement
   syncLimit=2
   # the directory where the snapshot is stored.
   # do not use /tmp for storage, /tmp here is just 
   # example sakes.
   dataDir=D:\\zookeeper\\data
   dataLogDir=D:\\zookeeper\\log
   # the port at which the clients will connect
   clientPort=2181
   # the maximum number of client connections.
   # increase this if you need to handle more clients
   #maxClientCnxns=60
   #
   # Be sure to read the maintenance section of the 
   # administrator guide before turning on autopurge.
   #
   # http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
   #
   # The number of snapshots to retain in dataDir
   #autopurge.snapRetainCount=3
   # Purge task interval in hours
   # Set to "0" to disable auto purge feature
   #autopurge.purgeInterval=1

3. 进入bin目录双击 zkServer.cmd，若启动成功，则windows单机版zookeeper搭建成功

2 dubbo-admin安装与使用

dubbo-admin git: https://github.com/apache/incubator-dubbo-ops下载。

注意：最新的dubbo-admin集成了springboot，能够打包为jar运行。

也能够从 https://gitee.com/jingyang3877/all-examples 直接下载jar包

执行如下命令打jar包：

mvn package -DskipTests=true

在jar包目录下，执行如下命令启动

java -jar dubbo-admin-xxx.jar

注意：dubbo-admin的端口默认是7001，dubbo注册中心的地址是本机的2181端口
