Dubbo剖析-管理控制台的搭建与使用

一、前言

开源的Dubbo的服务管理控制台是阿里巴巴内部裁剪版本，开源部分主要包含：路由规则，动态配置，服务降级，访问控制，权重调整，负载均衡，等管理功能。

二、管理控制台的搭建

2.1 打包生成管理控制台war包

• 下载源码 在 https://github.com/alibaba/dubbo/tree/2.5.x 下载dubbo的源码
• 解压源码，进入dubbo-2.5.x 目录，内容如下:

在该目录执行mvn clean package 会生成如下结果： [INFO] ------------------------------------------------------------------------ [INFO] Reactor Summary: [INFO] [INFO] dubbo-parent ......................................

进入/Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-admin/target目录，会发现生成了dubbo-admin-2.5.10.war：

image.png

• 拷贝dubbo-admin-2.5.10.war到servlet容器 本文使用tomcat容器，可以在 https://tomcat.apache.org/ 这里下载二进制包 然后拷贝dubbo-admin-2.5.10.war到apache-tomcat-7.0.10/webapps目录下并解压：

image.png

然后进入dubbo-admin-2.5.10/WEB-INF目录修改dubbo.properties文件：

image.png

这里只需要修改注册中心的地址即可，这里设置为zk的地址。

• 启动tomcat 在apache-tomcat-7.0.10/bin 下执行sh catalina.sh run启动tomcat. 启动后访问 http://127.0.0.1:8080/dubbo-admin-2.5.10/ 会出现下面界面：

image.png 用户名和密码输入root,进入下面界面：

image.png 说明管理控制台搭建完毕了。

三、管理控制台运维

3.1 搜索页面

当你需要管理 Dubbo 的服务时，首先要搜索到这个服务，然后打开它的管理页面，比如搜索：dubbo/com.test.UserServiceBo:1.0.0

单击右侧搜索按钮进入下面界面：

3.2 服务提供者页面

3.3 服务消费者页面

3.4 服务应用页面

四、总结

管理控制台不是使用dubbo搭建分布式系统必须的，但是有了他我们可以对服务进行很好的治理和监控。
