#### 单机Eureka构建步骤 ####

*  IDEA生成 EurekaServer端服务注册中心，类似物业公司
 *  Eurekaclient端 cloud- provider-payment8001将注册进 Eurekaserver成为服务提供者 provider,类似学校对外提供授课服务
 *  EurekaClient端 cloud- consumer-order.80将注册进 EurekaServer成为服务消费者 consumer类似来上课消费的同学

## IDEA生成 EurekaServer端服务注册中心，类似物业公司 ##

1、建Moudle  
**cloud-eureka-server7001**

2、改pom

    <project xmlns="http://maven.apache.org/POM/4.0.0"

        <dependencies>

                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>

            </dependency>
    
        </dependencies>
    
    
    </project>

3、写yml

server:
      port: 7001
    
    eureka:
      instance:
        hostname: localhost    #eureka服务端的实例名字
      client:
        register-with-eureka: false   #表识不向注册中心注册自己
        fetch-registry: false       #表示自己就是注册中心，职责是维护服务实例，并不需要去检索服务
        service-url:
          #设置与eureka server交互的地址查询服务和注册服务都需要依赖这个地址
          defaultZone:  http://${
        eureka.instance.hostname}:${
        server.port}/eureka/

4、主启动类

@EnableEurekaServer
    @SpringBootApplication
    public class EurekaMain7001 {
        
        public static void main(String[] args) {
        
            SpringApplication.run(EurekaMain7001.class,args);
        }
    }

5、测试  
http://localhost:7001

## Eurekaclient端 cloud- provider-payment8001将注册进 Eurekaserver成为服务提供者 provider,类似学校对外提供授课服务 ##

1、改pom

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>

2、写yml

server:
    eureka:
      client:
        register-with-eureka: true
        fetchRegistry: true
        service-url:
          defaultZone: http://localhost:7001/eureka

3、主启动

@EnableEurekaClient
    @SpringBootApplication
    public class PayMentMain8001 {
        
        public static void main(String[] args) {
        
        SpringApplication.run(PayMentMain8001.class,args);
        }
    }

4、测试  
先启动EurekaServer7001  
然后启动8001  
然后访问 http://localhost:7001/

## EurekaClient端 cloud- consumer-order.80将注册进 EurekaServer成为服务消费者 consumer类似来上课消费的同学 ##

1、改pom

<dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
            </dependency>

2、写yml

server:
      port: 80
    spring:
      application:
        name: cloud-order-service
    
    eureka:
      client:
        register-with-eureka: true
        fetchRegistry: true
        service-url:
          defaultZone: http://localhost:7001/eureka

3、给主启动加上@EnableEurekaClient

4、测试  
先启动7001，再启动8001，再启动80

①然后访问http://localhost:7001  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzIxMDQwNTU5_size_16_color_FFFFFF_t_70_pic_center 3]  
②http://localhost/consumer/payment/get/2 同样可以拿到结果
