Dubbo源码下载与编译

本文来讲下如何在Dubbo源码编译后，得到用于搭建管理控制台的war包和监控平台的jar包。

首先需要到[Github][]上下载Dubbo的源码，解压后如下：

![1057539-20180430122152834-1486340104.png][]

在dubbo-2.5.x目录执行 mvn clean package -Dmaven.test.skip=true 会生成如下结果：

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

进入/Users/xxx/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target目录，会发现生成了dubbo-monitor-simple-2.5.10-assembly.tar.gz。

管理控制台的搭建

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。

接着上面的操作，进入/Users/xxx/Downloads/dubbo-2.5.x/dubbo-admin/target目录，会发现生成了dubbo-admin-2.5.10.war。

![1057539-20180430123114866-1282383348.png][]

然后解压拷贝dubbo-admin-2.5.10.war后拷贝到一个Servlet容器，本文使用Tomcat容器，可以在[Tomcat 官网][Tomcat]下载Tomcat的二进制包，然后拷贝dubbo-admin-2.5.10到apache-tomcat-7.0.10/webapps 目录下：

![1057539-20180430123418786-1433330333.png][]

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

>     dubbo.registry.address=zookeeper://127.0.0.1:2181
>     dubbo.admin.root.password=root
>     dubbo.admin.guest.password=guest

这里的dubbo.registry.address为Zookeeper的地址。

最后在 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：

![1057539-20180523092041560-1358597608.png][]

用户名和密码都输入root后，单机登陆，进入下面界面：

![1057539-20180523092138968-837765959.png][]

至此说明管理控制台搭建完毕了。

现在你就可以使用管理控制台管理和查看服务信息了。

比如你可以搜索一个服务：dubbo/com.test.UserServiceBo:1.0.0。

![1057539-20180523092345210-606973291.png][]

单机搜索后页面跳转到：

![1057539-20180523092431426-643515952.png][]

比如你可以查看服务提供者：

![1057539-20180523092608043-225069349.png][]

比如比可以查看服务消费者：

![1057539-20180523092631167-2070120504.png][]

比如你可以查看当前都有哪些应用：

![1057539-20180523092721253-508607139.png][]

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

监控平台搭建

Dubbo-Monitor主要用来统计服务的调用次数和调用时间，服务消费者和提供者，在内存中累计调用次数和调用时间，定时每分钟发送一次统计数据到监控中心，监控中心则使用数据绘制图表来显示。

服务消费方和提供方需要显示开启Monitor。

如果使用Spring配置的服务消费方和提供方，则需要在对应xml添加下面配置：

>     <dubbo:monitor protocol="registry"/>

其中protocol为“registry”，表示服务提供方和消费方从服务注册中心发现监控中心（Monitor）地址。

如果使用的Dubbo API方式需要首先创建一个MonitorConfig对象。

>     MonitorConfig monitorConfig = new MonitorConfig();
>     monitorConfig.setProtocol("registry");

然后调用 reference.setMonitor(monitorConfig);设置到消费配置对象里面。

进入 /Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target 目录，会发现生成了 dubbo-monitor-simple-2.5.10-assembly.tar.gz:

![1057539-20180523094651532-2042249310.png][]'

解压 dubbo-monitor-simple-2.5.10-assembly.tar.gz,进入 dubbo-monitor-simple-2.5.10/conf/ 目录修改dubbo.properties:

>     dubbo.container=log4j,spring,registry,jetty
>     dubbo.application.name=simple-monitor
>     dubbo.application.owner=jiaduo
>     dubbo.registry.address=zookeeper://127.0.0.1:2181
>     dubbo.protocol.port=7070
>     dubbo.jetty.port=8081
>     dubbo.jetty.directory=/Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target/dubbo-monitor-simple-2.5.10/monitor
>     dubbo.charts.directory=/Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target/dubbo-moniotr-simple-2.5.10/charts
>     dubbo.statistics.directory=/Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target/dubbo-monitor-simple-2.5.10/monitor/statistics
>     dubbo.log4j.file=logs/dubbo-monitor-simple.log
>     dubbo.log4j.level=WARN

其中 dubbo.registry.address=zookeeper://127.0.0.1:2181 设置注册中心地址，这里设置为Zookeeper的地址。

dubbo.protocol.port=7070,是Monitor提供的远程服务监听端口，服务提供者和消费者会调用这个端口提供的服务，发送统计信息到Monitor。

dubbo.charts.directory和dubbo.statistics.directory为Monitor本地存放的监控数据文件的位置。

dubbo.jetty.port=8081,设置Jetty容器的监听地址，类似于Tomcat的8080端口，这里设置为8081。

然后进入dubbo-monitor-simple-2.5.10/bin，执行 sh start.sh 启动Monitor：

![1057539-20180523112752473-1288977095.png][]

至此Monitor启动了，访问 http://127.0.0.1:8081/ 会出现下面界面：

![1057539-20180523112921209-1249330348.png][]

然后我们就可以使用监控平台做一些事情了。

比如服务查看：

![1057539-20180523113018962-684689764.png][]

比如应用程序查看：

![1057539-20180523113054629-834111868.png][]

比如调用情况统计：

![1057539-20180523113131086-1504907181.png][]

![1057539-20180523113156276-816094010.png][]

注：Dubbo-Monitor也不是使用Dubbo搭建分布式系统必须的组件，但是它用来统计服务的调用次数和调用时间的控制中心，这些数据有助于系统运维和调优。
