创建eureka注册中心（eureka-server）

在父工程下创建一个maven项目

<?xml version="1.0" encoding="UTF-8"?>

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>springcloud-demo</artifactId>
        <groupId>demo.cloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>eureka-server</artifactId>

    <name>eureka-server</name>

    <dependencies>
        <!-- 引入eureka-server依赖 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>
</project>

修改application.yml文件

server:
  port: 8761

eureka:
  instance:
    #注册中心地址
    hostname: localhost
  client:
    #是否将自己注册到Eureka服务中
    register-with-eureka: false
    #是否从Eureka服务中获取注册信息
    fetch-registry: false
    #Eureka发现服务与注册服务的地址
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka

spring:
  application:
    #服务名称
    name: eureka-server

启动应用程序
启动eureka注册中心只需要在启动程序添加@EnableEurekaServer注解

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurekaServerApplication.class, args);
    }
}

访问eureka注册中心界面
eureka-server是有界面的，启动应用后，访问http://localhost:8761 (对应application.yml中的端口)
