Spring cloud配置EurekaServer很简单，如果要在细节上配置更多，那么需要阅读一下官方文档。

首先是maven：

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>
        <groupId>org.springframework.boot</groupId>

        <version>2.2.0.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->

    <artifactId>server</artifactId>

    </properties>

        <!--        </dependency>-->
        <dependency>

            <scope>test</scope>
            <exclusions>

    </dependencies>

            <url>https://repo.spring.io/milestone</url>
        </repository>

</project>

其次就是配置：

server:
  address: 127.0.0.1
  port: 7000
  undertow:
    io-threads: 19
    worker-threads: 24
    buffer-size: 1024
    direct-buffers: true
    always-set-keep-alive: true

spring:
  application:
    name: eureka-server
  profiles:
    active: test


eureka:
  instance:
    appname: eureka-server
    virtual-host-name: eureka-server
    secure-virtual-host-name: eureka-server
#    non-secure-port: 6000
#    non-secure-port-enabled: true
#    secure-port: 6443
#    secure-port-enabled: true
    lease-renewal-interval-in-seconds: 15
    lease-expiration-duration-in-seconds: 45
    instance-id: ${server.address}:eureka-server-peer:${server.port}
    hostname: localhost
  client:
    register-with-eureka: true
    fetch-registry: true
    registry-fetch-interval-seconds: 30
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
  server:
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 1000

最后就是注解开启：

package com.test.server;

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


@EnableEurekaServer
@SpringBootApplication
public class ServerApplication {

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

}

使用浏览器打开http://127.0.0.1:7000就可以看到效果了。
