简单实现一个eureka集群搭建

eureka服务器端搭建

咱们打算配置一个双节点的eureka集群，因此首先修改一下/etc/hosts文件，添加以下：

127.0.0.1 eureka01 eureka02

• 项目结构

• pom相关配置

• 启动文件详情

@SpringBootApplication
@EnableEurekaServer
public class ServerApplication{

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

• 配置文件-配置eureka各节点

application-eureka01.properties

server.port=8080
spring.application.name=eureka-server
eureka.instance.hostname=eureka01
eureka.client.serviceUrl.defaultZone=http://eureka02:8090/eureka/
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
复制代码

application-eureka02.properties

server.port=8090
spring.application.name=eureka-server
eureka.instance.hostname=eureka02
eureka.client.serviceUrl.defaultZone=http://eureka01:8080/eureka/
eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false
复制代码

启动eureka服务注册中心：

java -jar eureka.jar --spring.profiles.active=eureka01
java -jar eureka.jar --spring.profiles.active=eureka02
复制代码

登录控制台（http://eureka01:8080或http://eureka01:8090）如图：
