1建立一個springboot的空專案，由於springcloud需要啟動的專案實在太多，我使用了maven的多模組方法。

建立完畢後，需要對pom檔案進行改造一下，pom檔案應該如下所示。

<?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"

            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>

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

</project>

2使用idea建立module，選擇一個eureka server。

使用idea建立module時，選擇這個。

同樣，要對pom檔案進行修改。

<?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>

    <groupId>com.duanss</groupId>
    <artifactId>eureka-server</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>eureka-server</name>
    <description>Demo project for Spring Boot</description>

    <parent>
        <groupId>com.duanss</groupId>
        <artifactId>spring-cloud-demo</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>

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

</project>

建立完eurekaserve還沒完，需要在application檔案中加入註解@EnableEurekaServer
EurekaServerApplication.java的程式碼如下：

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

在application.yml檔案中加入如下配置：

server:
    port: 8761
eureka:
    instance:
        hostname: localhost
    client:
        registerWithEureka: false
        fetchRegistry: false
        serviceUrl:
            defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
spring:
    application:
        name: eurka-server

• registerWithEureka，說明了不需要想eureka註冊eureka，就是不註冊自己
• fetchRegistry：說明自己是註冊服務

現在啟動專案，開啟http://locahost:8761，就可以看到eureka自帶的介面。
