1.到地址 https://github.com/alibaba/dubbo
https://pan.baidu.com/s/1i5zi5Sh
下载dubbo源码
2.解压缩zip文件到 “ D:\zookeeper\dubbo-master\dubbo-master” 目录下
3.打开命令操作模式，进入D:\技术资料\zookeeper\dubbo-master\dubbo-master\dubbo-admin目录下执行下面的编译命令
D:\技术资料\zookeeper\dubbo-master\dubbo-master\dubbo-admin> mvn package -Dmaven.skip.test=true
如果编译时报下面的错误，需要修改 D:\技术资料\zookeeper\dubbo-master\dubbo-master\dubbo-admin目录下的pom.xml文件
[ERROR] Failed to execute goal on project dubbo-admin: Could not resolve dependencies for project com.alibaba:dubbo-admin:war:2.5.4-SNAPSHOT: Could not find artifact com.alibaba:dubbo:jar:2.5.4-SNAPSHOT -> [Help 1]
将 <version>${project.parent.version}</version> 修改为<version>2.5.3</version>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>${project.parent.version}</version>
</dependency>
<dependency>
<groupId>com.alibaba</groupId>
<artifactId>dubbo</artifactId>
<version>2.5.3</version>
</dependency>
4.出现下面的提示，编译成功
5.编译成功后，在D:\技术资料\zookeeper\dubbo-master\dubbo-master\dubbo-admin\target目录下有下面的war包存在
6.把这个dubbo-admin-2.5.4-SNAPSHOT.war拷贝到 tomcat下的webapps目录下
7 修改tomcat的端口为8088,修改方法如下，打到conf下的文件 server.xml，因为zookeeper会用到8080的端口，所以为了不冲突，把Tomcat的端口改一下。记得一定要改！！！
8 启动tomcat后，tomcat启动命令为 C:\tomcat\bin>startup.bat，启动后，dubbo-admin-2.5.4-SNAPSHOT.war包会自动解压，在tomcat/webapps目录下生成一个dubbo-admin-2.5.4-SNAPSHOT文件夹
修改dubbo-admin-2.5.4-SNAPSHOT/WEB-INF/文件夹下的dubbo.properties文件为如下内容
9 先启动zookeeper,然后再启动tomcat,在浏览器输入 http://localhost:8088/dubbo-admin-2.5.4-SNAPSHOT/
弹出登录框
，输入root/root后，显示下面页面
