一、1個eureka-server

注意點：1、新建專案選擇Eureka Server

 2、啟動類加註解

 3、application.yml配置檔案

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
    #不讓eureka.server自己註冊自己
    register-with-eureka: false
    #將服務端配置成客戶端關閉時展示服務消失：僅僅用於開發環境，生產環境得開啟
    server:
      enable-self-preservation: false
spring:
  application:
    name: eureka-server
#server:
#  port: 8761
 

 1個Eureka-Client

1、新建專案：

2、啟動類加註解@EnableDiscoveryClient

@SpringBootApplication
@EnableDiscoveryClient
public class LearningApplication {

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

 3、application.yml檔案

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/
spring:
  application:
    name: eureka-client
 

二、兩或三個Eureka Server ，相互註冊

yml配置檔案

eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka/,http://localhost:8762/eureka/
    #不讓eureka.server自己註冊自己
    register-with-eureka: false
    #將服務端配置成客戶端關閉時展示服務消失：僅僅用於開發環境，生產環境得開啟
    server:
      enable-self-preservation: false
spring:
  application:
    name: eureka-server
