本文介绍搭建单机版的Eureka Server服务

1 创建项目，导入依赖

<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.yiidian</groupId>
	<artifactId>eureka-server</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.1.RELEASE</version>
		<relativePath />
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
		<!-- SpringCloud版本，F系列 -->
		<spring-cloud.version>Finchley.RC1</spring-cloud.version>
	</properties>

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

	<dependencyManagement>
		<dependencies>
			<!-- SpringCloud依赖，一定要放到dependencyManagement中，起到管理版本的作用即可 -->
			<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>

	<repositories>
		<repository>
			<id>spring-milestones</id>
			<name>Spring Milestones</name>
			<url>https://repo.spring.io/milestone</url>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</repository>
	</repositories>

</project>

2 配置Eureka

建立application.yml，内容如下：

server:
  port: 10086 # 端口

spring:
  application:
    name: eureka-server # serviceID

# 配置Eureka服务
eureka:
  client:
    fetch-registry: false  # 是否拉取Eureka服务器的注册信息，默认true。单机版false，集群版true
    register-with-eureka: false   #  是否向Eureka服务器注册  ，默认true。单机版false，集群版true
    service-url:  # 注册地址
      defaultZone: http://127.0.0.1:${server.port}/eureka

3 编写启动类

package com.yiidian;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@EnableEurekaServer  //开启Eurea Server
@SpringBootApplication
public class EurekaServerApplication {

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

}

4 运行并访问Eureka Server

运行启动类，浏览器访问： http://localhost:10086，效果如下：
