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

-Dapollo_profile=github -Dspring.datasource.url=jdbc:mysql: //localhost:3306/ApolloConfigDB?characterEncoding=utf8 -Dspring.datasource.username=root -Dspring.datasource.password= Program arguments --configservice --adminservice |
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:

@Component 设置组件名称 @RefreshScope 指定配置改变可以刷新 @ConfigurationProperties (prefix = "redis.cache" ) @Component ( "sampleRedisConfig" ) @RefreshScope public class SampleRedisConfig { private static final Logger logger = LoggerFactory.getLogger(SampleRedisConfig. class ); private int expireSeconds; private String clusterNodes; private int commandTimeout; private Map<String, String> someMap = Maps.newLinkedHashMap(); private List<String> someList = Lists.newLinkedList(); @PostConstruct private void initialize() { logger.info( "SampleRedisConfig initialized - expireSeconds: {}, clusterNodes: {}, commandTimeout: {}, someMap: {}, someList: {}" , expireSeconds, clusterNodes, commandTimeout, someMap, someList); } public void setExpireSeconds( int expireSeconds) { this .expireSeconds = expireSeconds; } public void setClusterNodes(String clusterNodes) { this .clusterNodes = clusterNodes; } public void setCommandTimeout( int commandTimeout) { this .commandTimeout = commandTimeout; } public Map<String, String> getSomeMap() { return someMap; } public List<String> getSomeList() { return someList; } @Override public String toString() { return String.format( "[SampleRedisConfig] expireSeconds: %d, clusterNodes: %s, commandTimeout: %d, someMap: %s, someList: %s" , expireSeconds, clusterNodes, commandTimeout, someMap, someList); } } |
