application-peer1.yml
spring:
application:

server:
port: 7001
eureka:
instance:
instance-id: ${spring.cloud.client.ip-address}:${server.port}
hostname: peer1
# prefer-ip-address: true #以IP地址注册到服务中心，相互注册使用IP地址
# instance-id: ${spring.cloud.client.ipAddress}:${server.port}
# ip-address: #强制指定IP地址，默认会获取本机的IP地址

register-with-eureka: true # 表示是否注册自身到eureka服务器
fetch-registry: true # 是否从eureka上获取注册信息
serviceUrl:
defaultZone: http://peer2:7002/eureka/
server:
eviction-interval-timer-in-ms: 3000 # 续期时间，即扫描失效服务的间隔时间（单位毫秒，默认是60*1000）
enableSelfPreservation: false # 设为false，关闭自我保护
# renewalPercentThreshold: 0.49
logging:
config: classpath:log4j2.xml
Eureka2
同上，需要修改下application.yml的名字为application-peer2.yml ，server.port=7001
configServer1

configServer2
同configServer1，需要修改下bootstrap.yml的server.port=8768
configClient
bootstrap.yml
spring:
application:
name: config-client
cloud:
config:
name: application # 对应 {application} 部分
profile: dis-dev #指定的环境

logging:

一次启动项目，打开eureka监控网址，http://192.168.1.18:7001/
