本文详细介绍如何使用Zookeeper进行服务注册与发现，并通过Dubbo实现服务提供者与消费者的配置及部署过程。

下载并安装Zookeeper：

下载地址：http://www.apache.org/dist/zookeeper/

因为Zookeeper在启动时会找zoo.cfg这个文件作为默认配置文件，所以

启动Zookeeper

接着下载dubbo-admin

前往github上下载dubbo-admin：https://github.com/apache/incubator-dubbo/tree/dubbo-2.6.0

在dubbo-admin文件夹，输入cmd，打开dos窗口，输入以下命令

mvn  package -Dmaven.skip.test=true

打包好的war

将war包复制到tomcat的webapps文件夹下

在tomcat的bin目录下面，打开dos窗口，启动tomcat；成功启动后，关闭tomcat。这时候上图的dubbo-admin-2.6.0文件就出现了

用于指定zookeeper地址信息。默认的就是这个地址，不用改了

注：经测试，最好将Tomcat的【\webapps\ROOT】目录中的内容全部删除，然后将war包中的内容解压到其中，这样管理界面就成了Tomcat的默认应用，并且管理页面中的一些操作也不会发生404错误了。

账号密码是 root，root

启动我们项目中的服务

下面是我启动的启动类所在模块的applicationContext-dubbo-provider.xml配置文件的内容，即服务提供方
