1.在父项目spring-cloud-study项目中新建一个mavan模块 eureka-server-7001

2.修改子模块 pom.xml配置，引入spring-cloud-starter-netflix-eureka-server依赖，如下：

<?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>spring-cloud-study</artifactId>
        <groupId>org.andy.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
    <description>Eureka-server单实例服务中心 端口7001</description>
    <artifactId>eureka-server-7001</artifactId>


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

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>


</project>

3.新建服务中心启动类 com.andy.springcloud.server.EurekaServerApplication.java

package com.andy.springcloud.server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

/**
 * <h1>Eureka服务注册中心启动类</h1>
 * Created Time 2019/12/19 十二月 14:19
 * Created by   andy/aaa@qq.com
 */
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

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

}

4.在resources目录下新建application.yml并修改配置文件

server:
    port: 7001               # 服务中心端口

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

eureka:
    instance:
        hostname: eureka01    # hosts文件中配置的 别名
    client:
        fetch-registry: false #是否从服务器获取eureka注册信息
        register-with-eureka: false #是否将自己注册至eureka服务器
        service-url:
            defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka

5.子项目整体结构：
