開源配置中心 - Apollo
Apollo（阿波羅）是攜程框架部門研發(fā)的配置管理平臺，能夠集中化管理應用不同環(huán)境、不同集群的配置，配置修改后能夠?qū)崟r推送到應用端，并且具備規(guī)范的權(quán)限、流程治理等特性。服務端基于Spring Boot和Spring Cloud開發(fā)，打包后可以直接運行，不需要額外安裝Tomcat等應用容器。
檢出代碼
可以fork下然后本地使用idea打開
數(shù)據(jù)庫腳本
執(zhí)行以下腳本創(chuàng)建ApolloConifgDB、ApolloPortalDB
- apollo.scripts.sql.apolloconfigdb.sql
- apollo.scripts.sql.apolloportaldb.sql
啟動configservice adminservice

-Dapollo_profile=github -Dspring.datasource.url=jdbc:mysql://localhost:3306/ApolloConfigDB?characterEncoding=utf8 -Dspring.datasource.username=root -Dspring.datasource.password=Program arguments--configservice --adminservice |
啟動完后，打開 http://localhost:8080可以看到apollo-configservice和apollo-adminservice都已經(jīng)啟動完成并注冊到Eureka
啟動Apollo-Portal

如果啟用了auth profile的話，默認的用戶名是apollo，密碼是admin
應用在SIT、UAT、生產(chǎn)環(huán)境機器上
1.新增目錄/opt/data/目錄，且有可讀寫權(quán)限；
2.新增文件：/opt/settings/server.properties 且加入配置:

env=DEVsit: env=FATuat: env=UAT生產(chǎn)：env=PRO |
