Dubbo学习笔记3：Dubbo管理控制台与监控中心的搭建

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：

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。

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：

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：

用户名和密码都输入root后，单机登陆，进入下面界面：

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。

单机搜索后页面跳转到：

比如你可以查看服务提供者：

比如比可以查看服务消费者：

比如你可以查看当前都有哪些应用：

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:

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：
