spring Cloud服务注册中心Eureka集群

spring Cloud服务注册中心Eureka集群配置：

在application.yml文件加以下配置：

server:
  port: 8761
  tomcat:
    uri-encoding: UTF-8

eureka:
  instance:
    hostname: localhost
    # 优先使用IP地址方式进行注册服务
    prefer-ip-address: true
    appname: ${spring.application.name}
    # 表示eureka client发送心跳给server端的频率
    leaseRenewalIntervalInSeconds: 10
    # 表示eureka server至上一次收到client的心跳之后，等待下一次心跳的超时时间，
    # 在这个时间内若没收到下一次心跳，则将移除该instance (缺省为90*1000ms)
    leaseExpirationDurationInSeconds: 30

  server:
    # 关闭自我保护模式（缺省为打开）
    enableSelfPreservation: false
    # 续期时间，即扫描失效服务的间隔时间（缺省为60*1000ms）
    evictionIntervalTimerInMs: 4000

  client:
    # 是否注册自己
    register-with-eureka: true
    # 要不要去注册中心获取其他服务的地址
    fetch-registry: true
    service-url: 
      defaultZone: http://localhost:8762/eureka,http://localhost:8763/eureka

 

application-node1.yml文件加以下配置：

server:
  port: 8762
  tomcat:
    uri-encoding: UTF-8

eureka:
  instance:
    hostname: localhost
    prefer-ip-address: true   # 优先使用IP地址方式进行注册服务
    appname: ${spring.application.name}
    leaseRenewalIntervalInSeconds: 10
    leaseExpirationDurationInSeconds: 30

  server:
    enableSelfPreservation: false
    evictionIntervalTimerInMs: 4000

  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:8761/eureka,http://localhost:8763/eureka

application-node2.yml文件加以下配置：

server:
  port: 8763
  tomcat:
    uri-encoding: UTF-8

eureka:
  instance:
    hostname: localhost
    prefer-ip-address: true   # 优先使用IP地址方式进行注册服务
    appname: ${spring.application.name}
    leaseRenewalIntervalInSeconds: 10
    leaseExpirationDurationInSeconds: 30

  server:
    enableSelfPreservation: false
    evictionIntervalTimerInMs: 4000

  client:
    register-with-eureka: true
    fetch-registry: true
    service-url:
      defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka

bootstrap.yml配置应用名称：

spring:
  application:
    name: spring-cloud-eureka

 

配置java启动类node1、node2

 

 

 

启动EurekaApplication、node1、node2启动类，访问http://localhost:8761/、http://localhost:8762/、http://localhost:8763/成功则说明Eureka集群配置成功。
