3.spring cloud eureka 高可用

 

 

1、目的 防止某一台服务器宕机 通常通过多台EUREKA来为客户端进行注册，客户也进行注册

2、开启三台EUREKA

 

 

 三天EUREKA分别对应端口 8761 8762 8763

配置文件如下

EUREKA1

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8762/eureka,http://localhost:8763/eureka
    register-with-eureka: false
  server:
    enable-self-preservation: false
spring:
  application:
    name: eureka
#server:
# port: 8761
management:
  context-path: /

EUREKA2

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka,http://localhost:8763/eureka
    register-with-eureka: false
  server:
    enable-self-preservation: false
spring:
  application:
    name: eureka
#server:
# port: 8761
management:
  context-path: /

EUREKA3

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka
    register-with-eureka: false
  server:
    enable-self-preservation: false
spring:
  application:
    name: eureka
#server:
# port: 8761
management:
  context-path: /

CLIENT

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/,http://localhost:8762/eureka/,http://localhost:8763/eureka/
spring:
  application:
    name: client

3.启动客户端和三台EUREKA
