基础架构:
Eureka的基本功能:
eueka按逻辑上可以划分为3个模块,eureka-server,service-provider,service-consumer
eureka-server:服务端,提供服务注册和发现
eureka-client-service-provider:服务端,服务提供者,通过http rest告知服务端注册,更新,取消服务
eureka-client-service-consumer:客户端,服务消费者,通过http rest从服务端获取需要服务的地址列表,然后配合一些负载均衡策略(ribbon)来调用服务端服务。
值得注意的一点,不同于其他服务注册与发现(zookeeper需要单独以中间件的形式部署集群server),以上3个角色都是逻辑角色,甚至可以在相同的jvm进程上
注意:在该默认配置下,注册中心也会将自己作为客户端尝试注册自己,因此要禁用客户端注册行为
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
