动手搭建一个三个节点的eureka集群

搭建一个三个节点的eureka集群

jdk1.8、spring boot2.7.1 、spring-cloud2021.0.3

eureka-colony
eureka1
eureka2
eureka3

分别为 8761、8762、8763

为了在同一台机器上能同时运行三个eureka而不导致冲突，修改主机host文件(C:WindowsSystem32driversetc)

将127.0.0.1映射为如下三个地址:

127.0.0.1 eureka1.com
127.0.0.1 eureka2.com
127.0.0.1 eureka3.com

然后依次构建三个微服务，做好配置

访问：http://eureka1.com:8761/

可以看到你中有我，我中有你

自此，eureka集群搭建成功

spring:
  application:
    name: eureka1

server:
  port: 8761

eureka:

  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://eureka2.com:8762/eureka,http://eureka3.com:8763/eureka
  instance:
    hostname: eureka1.com
    prefer-ip-address: true

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

@SpringBootApplication
@EnableEurekaServer
public class Eureka1Application {

    public static void main(String[] args) {
        SpringApplication.run(Eureka1Application.class, args);
    }

}
