常见问题总结本章代码

1、1. Eureka1.1. Eureka Environment 的配置：参考文档：/Netflix/eureka/wiki/Configuring-Eureka1.2. Eureka Denter 的配置/Netflix/eureka/wiki/Configuring-Eureka这边说：配置-Deureka.denter=cloud，这样eureka 将会知道是在 AWS 云上1.3. Eureka 开启自我保护的提示1.4. Eureka服务慢如何解决？eureka.instance.leaseRenewalervalInSeconds参考文档：原文：Why is it so Slow

3、reservation: false evictionervalTimers: t.healthcheck.enabled = true开启健康检查（需要 spring-boot-starter-actuator 依赖）eureka.instance.lease-renewal-erval-in-seconds =10租期更新时间间隔（默认 30 秒）eureka.instance.lease-expiration-duration-in-seconds =30租期到期时间（默认 90 秒）eureka.server.enable-self-preservation（设为 false，关闭自我

4、保护主要） eureka.server.eviction-erval-timer-s间隔（毫秒，默认是 60*1000）作为实例还涉及到与中心的周期性心跳，默认持续时间为 30 秒（通过 serviceUrl）。在实例、服务器、客户端都在本地缓存中具有相同的元数据之前，服务不可用于客户端发现（所以可能需要 3 次心跳）。你可以使用 eureka.instance.leaseRenewalervalInSeconds 配置，这将加快客户端连接到其他服务的过程。在生产中，最好坚持使用默认值，因为在服务器有一些计算，他们对续约做出假设。Being an instance also involves

5、riodic heartbeat to the registry (via the c nts serviceUrl) with defau uration 30 seconds. A service is not available for discovery by c nts until the instance, the server and the c nt all have the same metadata heir local cache (so it could take 3 heartbeats). You can change the period using eureka

6、.instance.leaseRenewal ervalInSeconds and this will speed up the pro s of getting c nts connected to other servi . In production its probably better to stick with the default because there are some compu ions ernally he server t make a mptions about the lease renewal period.注意：更改 Eureka 更新频率将打破服务器的自
