注册中心是Spring Cloud的一大特性。Eureka是官方提供的注册中心组件，当然也有Consul等组件，本篇主要介绍Eureka单服务的使用。
打开IDEA工具，File-NEW-Project新建项目，选择Spring Initializr工具
点击下一步，完成。等待程序加载完成。
自动生成的pom文件如下

解析：
<spring-cloud.version>Greenwich.RC2</spring-cloud.version> //spring cloud的版本号
<parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.1.1.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent>
// spring boot 的版本，spring cloud 是依赖于spring boot的。

// 以上是编译的配置，已经spring cloud的私服仓库配置
修改启动类，使其成为注册中心：
增加@EnableEurekaServer，使得当前项目成为一个注册中心
修改配置文件（application.yml）:
使用工具自动创建的配置文件是application.properties,我个人更喜欢yml（yaml）这种格式化的文件。默认文件内没有任何配置是空的，我们增加如下配置：
server:
port: 8761 #，项目端口，默认端口是8080,
启动项目：

上面报了一个错，找不到服务器，这是为什么呢？
这是因为默认eureka默认要从eureka注册中心获取注册信息，增加如下配置：
eureka:
client:
fetch-registry: false
#默认是true，官方api说明是：
Indicates whether this client should fetch eureka registry information from eureka
* server. 中文大意就是：是否客户端从eureka服务获取注册信息
重新启动。。。。。。。。。
没有报错！！！
请求http://127.0.0.1:8761：
到此，eureka注册中心创建完毕。
思考：
eureka:
client:
fetch-registry: false这个配置的实际应用是什么呢？
当生产环境下，eureka注册中心如果只有一个，这难免有高并发、高可用的问题，如果这个服务挂掉，所有服务都将瘫痪（其他服务都会注册到eureka注册中心），这时候，我们就需要多个服务注册与发现中心，这是时候就需要互相注册，已经获取注册表信息，此配置也就有了用处。
eureka注册中心的高可用，在下一节进行讲解
本人也是初学，知识涉入不深，如有问题，欢迎大家进行指正！！！
