dubbo-admin dubbo-monitor 安装

dubbo-admin：html

由于咱们不能直观的看到dubbo和zk上到底有什么服务（提供者），因此咱们须要一个可视化工具来方便咱们管理每个服务和每个节点。
dubbo-admin 就是dubbo的管理控制台java

须要的准备工做是你的Linux已经安装了git

jdk
Zookeeper
tomcat

github

编译java包还须要用到Maven，安装教程

redis

一、官网下载dubbo源码spring

Dubbo 在2.6版本时合并了dubbox 的分支，如今dubbo-admin也迁移到一个单独项目 apache/incubator-dubbo-opsexpress

在这个地址只能下载 apache-dubbo-2.5.0版本，这个里面带有admin
https://github.com/apache/incubator-dubbo/apache

新版本中apache-dubbo-2.7.0已经没有dubbo-admin了vim

转移到新项目 apache/incubator-dubbo-ops https://github.com/apache/incubator-dubbo-opscentos

总结：

打成war包，放到tomcat容器中，启动，访问，期间可能存在端口冲突，主要使用于dubbo2.5.x以前的版本
打成jar包，经过java -jar xxx.jar命令启动，访问，dubbo2.6.0以后开始使用该方式

旧版本的安装流程
1.下载
2、编译dubbo-admin工程，打成war包     dubbo-admin-2.5.8.war
 3、进入 WEB-INF 目录修改文件 dubbo.properties 设置zookeeper 地址 dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.admin.root.password=root dubbo.admin.guest.password=guest 4、在tomcat 中部署dubbo-admin-2.5.8.war 5、用户密码都root/root

新版本安装流程

### 生产环境配置

1. 下载代码: `git clone https://github.com/apache/incubator-dubbo-ops.git`
2. 在 `dubbo-admin-server/src/main/resources/application-production.properties`中指定注册中心地址
3. 构建

> - `mvn clean package`
4. 启动
* `mvn --projects dubbo-admin-server spring-boot:run`
或者
* `cd dubbo-admin-distribution/target; java -jar dubbo-admin-0.1.jar`
5. 访问 `http://localhost:8080`

dubbo-Monitor：

dubbo-monitor-simple是dubbo提供的简单监控中心，能够用来显示接口暴露，注册状况，也能够看接口的调用明细，调用时间等。

Simple Monitor挂掉不会影响到Consumer和Provider之间的调用，因此用于生产环境不会有风险。
Simple Monitor采用磁盘存储统计信息，请注意安装机器的磁盘限制，若是要集群，建议用mount共享磁盘。
charts目录必须放在jetty.directory下，不然页面上访问不了。
配置好了以后能够结合admin管理后台使用，能够清晰的看到服务的访问记录、成功次数、失败次数。

下面是官网的安装步骤

安装: git clone https://github.com/apache/incubator-dubbo-ops
cd incubator-dubbo-ops && mvn package cd dubbo-monitor-simple/target && tar xvf dubbo-monitor-simple-2.0.0-assembly.tar.gz cd dubbo-monitor-simple-2.0.0 配置: vi conf/dubbo.properties 启动: ./assembly.bin/start.sh 中止: ./assembly.bin/stop.sh 重启: ./assembly.bin/restart.sh 调试: ./assembly.bin/start.sh debug 系统状态: ./assembly.bin/dump.sh 总控入口: ./assembly.bin/server.sh start ./assembly.bin/server.sh stop ./assembly.bin/server.sh restart ./assembly.bin/server.sh debug ./assembly.bin/server.sh dump 标准输出: tail -f logs/stdout.log 命令行 [1]: telnet 127.0.0.1 7070 help 或者: echo status | nc -i 1 127.0.0.1 7070 访问: http://127.0.0.1:8080

个人安装步骤

1. 下载源码（托管在github上） ~]# wget https://github.com/alibaba/dubbo/archive/dubbo-2.6.0.zip
~]# unzip dubbo-2.6.0.zip
~]# cd dubbo-dubbo-2.6.0/

2. 安装依赖 ~]# yum -y install java-1.8.0-openjdk maven maven: 用于编译dubbo-simple-monitor jdk: dubbo-simple-monitor是java语言所写，故须要jdk 3. 编译dubbo-simple-monitor dubbo-dubbo-2.6.0]# cd dubbo-simple/dubbo-monitor-simple/ dubbo-monitor-simple]# mvn clean install

编译成功后的目标文件为：target/dubbo-monitor-simple-2.6.0-assembly.tar.gz

进入target文件夹
能够直接下载我编译好的包

4. 修改配置文件 咱们使用dubbo-monitor-simple-2.6.0-assembly.tar.gz启动程序，由于还有一些配置须要修改 target]# tar xf dubbo-monitor-simple-2.6.0-assemble.tar.gz -C /usr/local target]# cd /usr/local local]# vim dubbo-monitor-simple-2.6.0/conf/dubbo.properties # Licensed to the Apache Software Foundation (ASF) under one or more # contributor license agreements.

dubbo.registry.address=zookeeper://127.0.0.1:2181 zookeeper的地址
#dubbo.registry.address=redis://127.0.0.1:6379
#dubbo.registry.address=dubbo://127.0.0.1:9090
dubbo.protocol.port=7070 dubbo.jetty.port=8080 服务启动后访问的端口（修改一下，不要和tomcat冲突）  dubbo.jetty.directory=/data/monitor dubbo.charts.directory=${dubbo.jetty.directory}/charts dubbo.statistics.directory=/data/monitor/statistics dubbo.log4j.file=logs/dubbo-monitor-simple.log dubbo.log4j.level=WARN

5. 启动服务 dubbo-monitor-simple-2.6.0]# bin/start.sh

报错：

2018-07-06 16:18:37,135 [main] WARN  com.alibaba.dubbo.config.ServiceConfig (ServiceConfig.java:568) -  [DUBBO] lvs: lvs: Temporary failure in name resolution, dubbo version: 2.6.0, current host: 127.0.0.1 java.net.UnknownHostException: lvs: lvs: Temporary failure in name resolution at java.net.InetAddress.getLocalHost(InetAddress.java:1505) at com.alibaba.dubbo.config.ServiceConfig.findConfigedHosts(ServiceConfig.java:566) at com.alibaba.dubbo.config.ServiceConfig.doExportUrlsFor1Protocol(ServiceConfig.java:469) at com.alibaba.dubbo.config.ServiceConfig.doExportUrls(ServiceConfig.java:357) at com.alibaba.dubbo.config.ServiceConfig.doExport(ServiceConfig.java:316) at com.alibaba.dubbo.config.ServiceConfig.export(ServiceConfig.java:215) at com.alibaba.dubbo.config.spring.ServiceBean.onApplicationEvent(ServiceBean.java:121) at com.alibaba.dubbo.config.spring.ServiceBean.onApplicationEvent(ServiceBean.java:50)

解决：修改hosts文件，把服务器名称 lvs 和 127.0.0.1 地址作一下映射就行了

# vi /etc/hosts 加入 127.0.0.1  lvs

出现的错误

1.

# ./start.sh ./start.sh: line 30: netstat: command not found Starting the simple-monitor ...../start.sh: line 79: netstat: command not found ../start.sh: line 79: netstat: command not found

提示找不到netstat命令，centos7 默认不使用这个命令了。
咱们安装一下network工具包，就可使用这个命令了

# yum install net-tools

2.

访问时没法看到图

解决

dubbo-simple-monitor配置文件中dubbo.jetty.directory中指明的目录须要手动建立
咱们须要监控的服务在配置dubbo时要加入<dubbo:monitor protocol="registry"/>这项配置
