准备工作

Eureka-client一个，Eureka-server一个，config-server一个

1.1 pom的准备

config-server

        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-config-server</artifactId>        </dependency>

eureka-client和Eureka-server都添加

        <dependency>            <groupId>org.springframework.cloud</groupId>            <artifactId>spring-cloud-starter-config</artifactId>        </dependency>

1.2 配置文件
eureka-client

server:  port: 8081spring:  application:    name: eureka-client1eureka:  instance:    hostname: localhost    prefer-ip-address: true  client:    service-url:      default-zone: http://localhost:8761/eureka/

eureka-server

server:  port: 8761eureka:  instance:    hostname: localhost    prefer-ip-address: true  client:    service-url:      default-zone: http://${eureka.instance.hostname}:${server.port}/eureka/    register-with-eureka: false    fetch-registry: false  server:    wait-time-in-ms-when-sync-empty: 0    enable-self-preservation: false

config-server
目录结构

application.yml

server:  port: 8888spring:  application:    name: config-server  profiles:    active: native

eureka-client.yml

server:  port: 8081spring:  application:    name: eureka-client1eureka:  client:    service-url:      default-zone: http://localhost:8761/eureka/

eureka-server-peer1.yml

server:  port: 8761eureka:  instance:    hostname: localhost    prefer-ip-address: true  client:    service-url:      default-zone: http://localhost:8761/eureka/    register-with-eureka: true    fetch-registry: true  server:    wait-time-in-ms-when-sync-empty: 0    enable-self-preservation: false

然后先后启动config-server、eureka-server、eureka-client
