### 高可用服务注册中心 ###

1.  创建两个服务注册中心

2.  添加依赖   注意更改一下artifactId

<?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">

        </dependencies>
    
        <dependencyManagement>

            <plugins>
                <plugin>

                    <artifactId>spring-boot-maven-plugin</artifactId>
                </plugin>
            </plugins>
        </build>
    
    </project>

3.  分别配置配置文件

server.port=7998
    eureka.client.register-with-eureka=false
    eureka.client.fetch-registry=false
    spring.application.name=eureka-server
    eureka.instance.hostname=one
    eureka.client.serviceUrl.defaultZone=http://three:7999/eureka/
    
    #---------------------
    
    server.port=7999
    eureka.client.register-with-eureka=false
    eureka.client.fetch-registry=false
    spring.application.name=eureka-server
    eureka.instance.hostname=three
    eureka.client.serviceUrl.defaultZone=http://one:7998/eureka/

4.  在主函数上添加注册中心的注释  @EnableEurekaServer

5.  配置服务提供方 注册到注册中心集群

spring.application.name=demo-server
    eureka.client.service-url.defaultZone=http://one:7998/eureka/,http://three:7999/eureka/
