1、创建artifactId为microservice-discovery-eureka的maven工程。（spring boot 为2.0.3）

<parent>
          <groupId>org.springframework.boot</groupId>
          <artifactId>spring-boot-starter-parent</artifactId>
          <version>2.0.3.RELEASE</version>
          <relativePath/> 
       </parent>
    
       <dependencies>
          <dependency>
             <groupId>org.springframework.cloud</groupId>
             <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
          </dependency>
    
          <dependency>
             <groupId>org.springframework.boot</groupId>
             <artifactId>spring-boot-starter-test</artifactId>
             <scope>test</scope>
          </dependency>
       </dependencies>
    
       <dependencyManagement>
          <dependencies>
             <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
             </dependency>
          </dependencies>
       </dependencyManagement>

2、编写启动类，增加@EnableEurekaServer注解，声明为eureka server。

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

3、配置application.yml。

server:
      port: 8764
    eureka:
      client:
        register-with-eureka: false # 是否将应用注册到Eureka server上，当前应用为server，设置为false
        fetch-registry: false # 从eureka获取注册信息
        service-url:
           defaultZone: http://localhost:8764/eureka/  #defaultZone不能替换为default-zone(本人踩过的坑)

4、运行mvn spring-boot:run运行项目

5、结果如图
