2021/10/31 Apollo配罝中心

[TOC]

一、簡介

Apollo是中國携程框架研發部所開發的開源項目，實現分布式的配管理中心，本文章是基於官方文檔整理的布署筆記，細節可以查看官網

二、架構圖

說明：

Apolloe 是由Portal、Admin、Config 三個模塊組成，Portal主要是管理後台，再通過不同的配罝，訪問不同環境的配罝中心，若實際應用上有需要DEV、UAT、PRO三個環境，則會需要三套Admin+Config

三、布署

3.執行 & 導入數據

啟動 docker-compose

>> docker-compose up -d

由於是使用MySQL8，密碼認證需要更改

注：請自行加固密碼安全

>> docker exec -it apollo-db mysql -uroot -pP@ssw0rd -e "ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY 'P@ssw0rd';"

創建數據庫

>> mysql -h 192.168.1.17 -u root -pP@ssw0rd -e 'CREATE DATABASE ApolloPortalDB DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;'
>> mysql -h 192.168.1.17 -u root -pP@ssw0rd -e 'CREATE DATABASE ApolloConfigDevDB DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;'
>> mysql -h 192.168.1.17 -u root -pP@ssw0rd -e 'CREATE DATABASE ApolloConfigUatDB DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;'
>> mysql -h 192.168.1.17 -u root -pP@ssw0rd -e 'CREATE DATABASE ApolloConfigProDB DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;'

導入數據

>> wget https://raw.githubusercontent.com/apolloconfig/apollo-build-scripts/master/sql/apolloconfigdb.sql
>> wget https://raw.githubusercontent.com/apolloconfig/apollo-build-scripts/master/sql/apolloportaldb.sql
# 需要修改 apolloconfigdb.sql，移除創建數據庫SQL

>> mysql -h 192.168.1.17 -u root -pP@ssw0rd ApolloPortalDB < apolloportaldb.sql 
>> mysql -h 192.168.1.17 -u root -pP@ssw0rd ApolloConfigDevDB < apolloconfigdb.sql
>> mysql -h 192.168.1.17 -u root -pP@ssw0rd ApolloConfigUatDB < apolloconfigdb.sql 
>> mysql -h 192.168.1.17 -u root -pP@ssw0rd ApolloConfigProDB < apolloconfigdb.sql

修改各環境admin讀取config服務的URL

>> mysql -h 192.168.1.17 -u root -p 
>> UPDATE ApolloConfigDevDB.ServerConfig SET `value`='http://apollo-config-dev:8080/eureka/' WHERE `key`='eureka.service.url';
>> UPDATE ApolloConfigUatDB.ServerConfig SET `value`='http://apollo-config-uat:8080/eureka/' WHERE `key`='eureka.service.url';
>> UPDATE ApolloConfigProDB.ServerConfig SET `value`='http://apollo-config-pro:8080/eureka/' WHERE `key`='eureka.service.url';

四、測試

可以訪問個環境的Admin頁面，確認服務是否正常啟用，如 192.168.1.17:18080

訪問 Portal 頁面(192.168.1.17:8070)，默認帳密 apollo/admin

測試配罝文件的抓取，不同URL代表不同環境，沒異常的話，就可以給程序正常調用

>> curl 'http://192.168.1.17:18080/configs/SampleApp/default/application'
{"appId":"SampleApp","cluster":"default","namespaceName":"application","configurations":{"timeout":"100"},"releaseKey":"20211101001334-1dc5a1de1881599c"}
>> curl 'http://192.168.1.17:28080/configs/SampleApp/default/application'
{"appId":"SampleApp","cluster":"default","namespaceName":"application","configurations":{"timeout":"100"},"releaseKey":"20211101001349-1dc5adf81c2a26a2"}
>> curl 'http://192.168.1.17:38080/configs/SampleApp/default/application'
{"appId":"SampleApp","cluster":"default","namespaceName":"application","configurations":{"timeout":"100"},"releaseKey":"20211101001400-1dc5a7eb1af82f79"}
