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。

10.1.22.27:8762
10.1.22.28:8762

1、Eureka服务端集群配置文件

#多服务器HA

spring:

  application:

    name: mima-cloud-eureka-ha

management:

  security:

    enabled: false

---
#启动命令nohup java -jar mima-cloud-eureka-ha.jar --spring.profiles.active=peer1 &

server:

  port: 8762

spring:

  profiles: peer1

eureka:

  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: 8762

spring:

  profiles: peer2

eureka:

  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: 8762

spring:

  profiles: peer3

eureka:

  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/

2、Eureka客户端集群配置文件

debug: true

spring:

  application:

    name: mima-cloud-producer

server:

  port: 9906

eureka:

  instance:

    prefer-ip-address: true

    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${server.port}

  client:

    serviceUrl:

      #如果需要使用主机名,则需要配置服务器的/etc/hosts文件
defaultZone: http://10.1.22.26:8762/eureka/,http://10.1.22.27:8762/eureka/,http://10.1.22.28:8762/eureka/
