Eureka+Config集群搭建配置中心

根据前面搭建Eureka 和 Config集群的经验，下面讲Eureka+Config集群搭建的配置中心。

Eureka2

同上，需要修改下application.yml的名字为application-peer2.yml ，server.port=7001

configServer1

    config:
      server:
        git:

    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true #以IP地址注册到服务中心
    lease-renewal-interval-in-seconds: 5      # 心跳时间，即服务续约间隔时间（缺省为30s）
    lease-expiration-duration-in-seconds: 15  # 发呆时间，即服务续约到期时间（缺省为90s）

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
      label: master                      #指定分支
      discovery:
        enabled: true
        service-id: config-server

management:
  endpoints:
    web:
      exposure:
        include: refresh

eureka:
  client:
    serviceUrl:
        defaultZone: http://192.168.1.18:7001/eureka/,http://192.168.1.18:7002/eureka/
  instance:
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true #以IP地址注册到服务中心

    lease-renewal-interval-in-seconds: 5      # 心跳时间，即服务续约间隔时间（缺省为30s）
    lease-expiration-duration-in-seconds: 15  # 发呆时间，即服务续约到期时间（缺省为90s）

logging:
  config: classpath:log4j2-dev.xml

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