背景

Dubbo的开源人梁飞在内部的交流会上宣布重启dubbo的维护和更新，具体PPT内容请看我的个人订阅号。

因此本文基于2017-12-10号的维护的版本dubbo-2.5.7。

这里为何从Dubbo-admin开始，这不是最重要的部分，但是却是dubbo源码编译最简单的部分。

准备工作

按照zookeeper服务（参考单机安装zookeeper安装）

下载dubbo源码 
https://github.com/alibaba/dubbo/releases/tag/dubbo-2.5.7

当然也可以直接从我的github上面直接下载已经编译好了的war包 
https://github.com/BambooZhang/dubbo-study

编译

解压后这里只用到一个项目就是dubbo-admin

cd D:\git_space\dubbo-dubbo-2.5.7\dubbo-dubbo-2.5.7\dubbo-admin mvn package -Dmaven.skip.test=true 

出现下面的结果则说明编译成功

[INFO]
[INFO] --- maven-war-plugin:2.2:war (default-war) @ dubbo-admin ---

部署dubbo-admin到tomcat

把target\dubbo-admin-2.5.7下面的文件都拷贝到tomcat/webapps/ROOT下面

修改配置dubbo.properties 
zookeeper地址修改为自己安装的ip地址，默认是127.0.0.1

dubbo.registry.address=zookeeper://192.168.0.91:2181 dubbo.admin.root.password=root dubbo.admin.guest.password=guest

启动dubbo-admin

首先启动zookeeper服务，在启动tomcat 
启动完成访问localhost:8080 
默认账号密码都是root 

Dubbo服务提供者和消费者demo

dubbo-admin-2.5.7.war管理中心 
dubbo-provider服务器提供者 
dubbo-consumer服务器消费者

spring版本：4.3.9.RELEASE
