Dubbo源碼下載與編譯

本文來講下如何在Dubbo源碼編譯后，得到用於搭建管理控制台的war包和監控平台的jar包。

首先需要到Github上下載Dubbo的源碼，解壓后如下：

在dubbo-2.5.x目錄執行 mvn clean package -Dmaven.test.skip=true 會生成如下結果：

進入/Users/xxx/Downloads/dubbo-2.5.x/dubbo-admin/target目錄，會發現生成了dubbo-admin-2.5.10.war。

進入/Users/xxx/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target目錄，會發現生成了dubbo-monitor-simple-2.5.10-assembly.tar.gz。

管理控制台的搭建

開源的Dubbo的服務管理控制台是阿里巴巴內部裁剪版本，開源部分主要包含：路由規則/動態配置/服務降級/訪問控制/權重調整/負載均衡等管理功能。

接着上面的操作，進入/Users/xxx/Downloads/dubbo-2.5.x/dubbo-admin/target目錄，會發現生成了dubbo-admin-2.5.10.war。

然后解壓拷貝dubbo-admin-2.5.10.war后拷貝到一個Servlet容器，本文使用Tomcat容器，可以在Tomcat 官網下載Tomcat的二進制包，然后拷貝dubbo-admin-2.5.10到apache-tomcat-7.0.10/webapps 目錄下：

然后進入 dubbo-admin-2.5.10/WEB-INF目錄修改dubbo.properties文件：

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

這里的dubbo.registry.address為Zookeeper的地址。

最后在 apache-tomcat-7.0.10/bin 下執行 sh catalina.sh run 啟動Tomcat。

啟動后訪問 http://127.0.0.1:8080/dubbo-admin-2.5.10/ 會出現下面界面：

用戶名和密碼都輸入root后，單機登陸，進入下面界面：

至此說明管理控制台搭建完畢了。

現在你就可以使用管理控制台管理和查看服務信息了。

比如你可以搜索一個服務：dubbo/com.test.UserServiceBo:1.0.0。

單機搜索后頁面跳轉到：

比如你可以查看服務提供者：

比如比可以查看服務消費者：

比如你可以查看當前都有哪些應用：

注：管理控制台不是使用Dubbo搭建分布式系統必須的，但是有了它我們可以對服務進行很好的治理和監控。

監控平台搭建

Dubbo-Monitor主要用來統計服務的調用次數和調用時間，服務消費者和提供者，在內存中累計調用次數和調用時間，定時每分鍾發送一次統計數據到監控中心，監控中心則使用數據繪制圖表來顯示。

服務消費方和提供方需要顯示開啟Monitor。

如果使用Spring配置的服務消費方和提供方，則需要在對應xml添加下面配置：

<dubbo:monitor protocol="registry"/>

其中protocol為“registry”，表示服務提供方和消費方從服務注冊中心發現監控中心（Monitor）地址。

如果使用的Dubbo API方式需要首先創建一個MonitorConfig對象。

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

然后調用 reference.setMonitor(monitorConfig);設置到消費配置對象里面。

進入 /Users/zhuizhumengxiang/Downloads/dubbo-2.5.x/dubbo-simple/dubbo-monitor-simple/target 目錄，會發現生成了 dubbo-monitor-simple-2.5.10-assembly.tar.gz:

解壓 dubbo-monitor-simple-2.5.10-assembly.tar.gz,進入 dubbo-monitor-simple-2.5.10/conf/ 目錄修改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 設置注冊中心地址，這里設置為Zookeeper的地址。

dubbo.protocol.port=7070,是Monitor提供的遠程服務監聽端口，服務提供者和消費者會調用這個端口提供的服務，發送統計信息到Monitor。

dubbo.charts.directory和dubbo.statistics.directory為Monitor本地存放的監控數據文件的位置。

dubbo.jetty.port=8081,設置Jetty容器的監聽地址，類似於Tomcat的8080端口，這里設置為8081。

然后進入dubbo-monitor-simple-2.5.10/bin，執行 sh start.sh 啟動Monitor：
