配置Eureka集群注册中心

1.本机集群时需要使用域名，配置 localhost 和 127.0.0.1的时候集群不可用(集群模式会显示unavailable-replicas)

2.非本机环境使用ip地址的形式进行注册，添加：

eureka:

instance:

prefer-ip-address: true

3.注意yml首尾字母的间隔

启动时指定profiles即可

java -jar -Xms512m -Xmx1024m xxxxx.jar --spring.profiles.active=dev1

application.yml配置信息：

#公共配置

spring:

application:

name: registry

eureka:

#dashboard:

#enabled: true

#path: /admin #访问eureka时地址上带admin

server:

eviction-interval-timer-in-ms: 5000 #清理无效节点的时间 5秒

enable-self-preservation: false #关闭自我保护模式

##127.0.0.1 eureka1

##127.0.0.1 eureka2

eureka:

instance:
