1.新建一个父工程，指定springBoot版本和springCloud版本

pom.xml

>     <?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">
>         <modelVersion>4.0.0</modelVersion>
>     
>         <parent>
>             <groupId>org.springframework.boot</groupId>
>             <artifactId>spring-boot-starter-parent</artifactId>
>             <version>1.5.21.RELEASE</version>
>             <relativePath/> 
>         </parent>
>     
>         <groupId>com.l2cplat</groupId>
>         <artifactId>l2cplat-cloud</artifactId>
>         <version>0.0.1-SNAPSHOT</version>
>         <packaging>pom</packaging>
>         <name>l2cplat-cloud</name>
>     
>         <description>Demo project for Spring Boot</description>
>

>                 <url>https://8090ip.com</url>
>                 <email>java0928@126.com</email>
>             </developer>
>         </developers>
>     
>         <modules>
>             <module>l2cplat-cloud-common</module>
>             <module>l2cplat-cloud-eureka</module>
>             <module>l2cplat-cloud-card</module>
>         </modules>
>     
>         <properties>
>             <java.version>1.8</java.version>
>             <spring-cloud.version>Edgware.SR6</spring-cloud.version>
>         </properties>
>     
>         
>         <dependencyManagement>
>             <dependencies>
>                 <dependency>
>                     <groupId>org.springframework.cloud</groupId>
>                     <artifactId>spring-cloud-dependencies</artifactId>
>                     <version>${spring-cloud.version}</version>
>                     <type>pom</type>
>                     <scope>import</scope>
>                 </dependency>
>             </dependencies>
>         </dependencyManagement>
>     
>         <dependencies>
>             <dependency>
>                 <groupId>org.springframework.boot</groupId>
>                 <artifactId>spring-boot-starter</artifactId>
>             </dependency>
>     
>             <dependency>
>                 <groupId>org.springframework.boot</groupId>
>                 <artifactId>spring-boot-starter-test</artifactId>
>                 <scope>test</scope>
>             </dependency>
>         </dependencies>
>     
>     </project>

2.在 父工程下新建一个module(eureka server),添加eurekaServer所需依赖

pom.xml

3.在启动类上添加eureka Server的启动注解

4.在资源文件下创建一个bootstrap.yml文件

application.yml

>     server:
>       port: 8761
>     
>     spring:
>       profiles:
>         active: dev
>       application:
>         name: @pom.name@

bootstrap.yml

>     eureka:
>       instance:
>         #当前eureka server实例名称
>         hostname: localhost
>         # 注册时使用ip而不是主机名
>         prefer-ip-address: true
>       client:
>         #由于该应用为Eu注册中心,所以设置为false,代表不向注册中心注册自己
>         registerWithEureka: false
>         #由于注册中心的职责就是维护服务实例,它并不需要去检索服务,所以也设置为false，不需要从ereka服务中获取注册
>         fetchRegistry: false
>       #Eureka注册和访问地址
>       serviceUrl:
>         defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka
>       #eureka自我保护机制
>     #  server:
>     #    enable-self-preservation: false
> 
>

5.启动eureka Server服务，在打开localhost:8761
