Spring Cloud Eureka Server配置

单实例Eureka Server配置

1. 依赖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"

            </plugin>
        </plugins>
    </build>

</project>

2. 配置application.yml

server:
  port: 8761

eureka:
  instance:
    hostname: localhost
  client:
    # 下面两行表明自己是一个EurekaServer服务
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

spring:
  application:
    name: Eureka-Server

3. 启动类

package com.zws.cloud.server;

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

@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

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

}

4. 访问：

http://localhost:8761/

Eureka Server集群配置

集群配置只在配置文件上有区别

1.Server1

server:
  port: 8761

eureka:
  instance:
    hostname: peer1
  client:
    # 下面两行表明自己是一个EurekaServer服务
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://peer2:8762/eureka/,http://peer3:8763/eureka/

spring:
  application:
    name: Eureka-Server1

2.Server2

server:
  port: 8762

eureka:
  instance:
    hostname: peer2
  client:
    # 下面两行表明自己是一个EurekaServer服务
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://peer1:8761/eureka/,http://peer3:8763/eureka/

spring:
  application:
    name: Eureka-Server2

3.Server3

server:
  port: 8763

eureka:
  instance:
    hostname: peer3
  client:
    # 下面两行表明自己是一个EurekaServer服务
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://peer1:8761/eureka/,http://peer2:8762/eureka/

spring:
  application:
    name: Eureka-Server3

4./etc/hosts配置

127.0.0.1 peer1
127.0.0.1 peer2
127.0.0.1 peer3
