开源配置中心 - Apollo
Apollo（阿波罗）是携程框架部门研发的配置管理平台，能够集中化管理应用不同环境、不同集群的配置，配置修改后能够实时推送到应用端，并且具备规范的权限、流程治理等特性。服务端基于Spring Boot和Spring Cloud开发，打包后可以直接运行，不需要额外安装Tomcat等应用容器。
检出代码
可以fork下然后本地使用idea打开
数据库脚本
执行以下脚本创建ApolloConifgDB、ApolloPortalDB
- apollo.scripts.sql.apolloconfigdb.sql
- apollo.scripts.sql.apolloportaldb.sql
启动configservice adminservice
Main class配置

启动完后，打开 http://localhost:8080可以看到apollo-configservice和apollo-adminservice都已经启动完成并注册到Eureka

如果启用了auth profile的话，默认的用户名是apollo，密码是admin
应用在SIT、UAT、生产环境机器上
1.新增目录/opt/data/目录，且有可读写权限；
2.新增文件：/opt/settings/server.properties 且加入配置:
