线上Eureka高可用集群，至少三个节点组成一个集群，推荐部署在不同的服务器上，IP用域名绑定，端口保持一致。

1、Eureka服务端集群配置文件

#多服务器HAspring:  application:    name: mima-cloud-eureka-hamanagement:  security:    enabled: false---#启动命令nohup java -jar mima-cloud-eureka-ha.jar --spring.profiles.active=peer1 &server:  port: 8762spring:  profiles: peer1eureka:  instance:    hostname: localhost    prefer-ip-address: true    instance-id: ${spring.application.name}:${server.port}  client:    serviceUrl:      defaultZone: http://10.1.22.27:8762/eureka/,http://10.1.22.28:8762/eureka/---#启动命令nohup java -jar mima-cloud-eureka-ha.jar --spring.profiles.active=peer2 &server:  port: 8762spring:  profiles: peer2eureka:  instance:    hostname: localhost    prefer-ip-address: true    instance-id: ${spring.application.name}:${server.port}  client:    serviceUrl:      defaultZone: http://10.1.22.26:8762/eureka/,http://10.1.22.28:8762/eureka/---#启动命令nohup java -jar mima-cloud-eureka-ha.jar --spring.profiles.active=peer3 &server:  port: 8762spring:  profiles: peer3eureka:  instance:    hostname: localhost    prefer-ip-address: true    instance-id: ${spring.application.name}:${server.port}  client:    serviceUrl:      defaultZone: http://10.1.22.26:8762/eureka/,http://10.1.22.27:8762/eureka/
