dubbo-admin dubbo-monitor 安裝

dubbo-admin：html

由於咱們不能直觀的看到dubbo和zk上到底有什麼服務（提供者），因此咱們須要一個可視化工具來方便咱們管理每個服務和每個節點。
dubbo-admin 就是dubbo的管理控制檯java

須要的準備工做是你的Linux已經安裝了git

jdk
Zookeeper
tomcat

github

編譯java包還須要用到Maven，安裝教程

redis

一、官網下載dubbo源碼spring

Dubbo 在2.6版本時合併了dubbox 的分支，如今dubbo-admin也遷移到一個單獨項目 apache/incubator-dubbo-opsexpress

在這個地址只能下載 apache-dubbo-2.5.0版本，這個裏面帶有admin
https://github.com/apache/incubator-dubbo/apache

新版本中apache-dubbo-2.7.0已經沒有dubbo-admin了vim

轉移到新項目 apache/incubator-dubbo-ops https://github.com/apache/incubator-dubbo-opscentos

總結：

打成war包，放到tomcat容器中，啓動，訪問，期間可能存在端口衝突，主要使用於dubbo2.5.x以前的版本
打成jar包，經過java -jar xxx.jar命令啓動，訪問，dubbo2.6.0以後開始使用該方式

舊版本的安裝流程
1.下載
2、編譯dubbo-admin工程，打成war包     dubbo-admin-2.5.8.war
 3、進入 WEB-INF 目錄修改文件 dubbo.properties 設置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、用戶密碼都root/root

新版本安裝流程

### 生產環境配置

1. 下載代碼: `git clone https://github.com/apache/incubator-dubbo-ops.git`
2. 在 `dubbo-admin-server/src/main/resources/application-production.properties`中指定註冊中心地址
3. 構建

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

dubbo-Monitor：

dubbo-monitor-simple是dubbo提供的簡單監控中心，能夠用來顯示接口暴露，註冊狀況，也能夠看接口的調用明細，調用時間等。

Simple Monitor掛掉不會影響到Consumer和Provider之間的調用，因此用於生產環境不會有風險。
Simple Monitor採用磁盤存儲統計信息，請注意安裝機器的磁盤限制，若是要集羣，建議用mount共享磁盤。
charts目錄必須放在jetty.directory下，不然頁面上訪問不了。
配置好了以後能夠結合admin管理後臺使用，能夠清晰的看到服務的訪問記錄、成功次數、失敗次數。

下面是官網的安裝步驟

安裝: 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 啓動: ./assembly.bin/start.sh 中止: ./assembly.bin/stop.sh 重啓: ./assembly.bin/restart.sh 調試: ./assembly.bin/start.sh debug 系統狀態: ./assembly.bin/dump.sh 總控入口: ./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 標準輸出: 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 訪問: http://127.0.0.1:8080

個人安裝步驟

1. 下載源碼（託管在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. 安裝依賴 ~]# yum -y install java-1.8.0-openjdk maven maven: 用於編譯dubbo-simple-monitor jdk: dubbo-simple-monitor是java語言所寫，故須要jdk 3. 編譯dubbo-simple-monitor dubbo-dubbo-2.6.0]# cd dubbo-simple/dubbo-monitor-simple/ dubbo-monitor-simple]# mvn clean install

編譯成功後的目標文件爲：target/dubbo-monitor-simple-2.6.0-assembly.tar.gz

進入target文件夾
能夠直接下載我編譯好的包

4. 修改配置文件 咱們使用dubbo-monitor-simple-2.6.0-assembly.tar.gz啓動程序，由於還有一些配置須要修改 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 服務啓動後訪問的端口（修改一下，不要和tomcat衝突）  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. 啓動服務 dubbo-monitor-simple-2.6.0]# bin/start.sh

報錯：

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)

解決：修改hosts文件，把服務器名稱 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

出現的錯誤

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 默認不使用這個命令了。
咱們安裝一下network工具包，就可使用這個命令了

# yum install net-tools

2.

訪問時沒法看到圖

解決

dubbo-simple-monitor配置文件中dubbo.jetty.directory中指明的目錄須要手動建立
咱們須要監控的服務在配置dubbo時要加入<dubbo:monitor protocol="registry"/>這項配置
