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
