1、空工程创建完成-创建注册中心模块

2、项目的pom依赖如下

3、在配置文件配置注册中心

server:
  port: 8761
  tomcat:
    uri-encoding: UTF-8
  servlet:
    application-display-name: RegisterCenter
eureka:
  instance:
    #eureka实例的主机名
    hostname: eureka-server
  client:
    register-with-eureka: false     #是否把服务注册中心注册到eureka
    fetch-registry: false           #是否从服务注册中心注册eureka获取注册信息
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
spring:
  application:
    name: RegisterCenter
  cloud:
    loadbalancer:
      ribbon:
        enabled: true

4、当前版本下需要新建config.properties配置文件作为动态配置（空文件即可）

否则会报如下warn

5、在启动类添加开启EurekaServer的注解 @EnableEurekaServer

package com.fcant.register_center;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaServer
@SpringBootApplication
public class RegisterCenterApplication {
    public static void main(String[] args) {
        SpringApplication.run(RegisterCenterApplication.class, args);
    }
}

6、启动注册中心，并访问管理页面

http://localhost:8080/
