Eureka Server & Eureka Client & Eureka Consumer 使用

參考代碼：https://mrbird.cc/Spring-Cloud-Eureka.html

本篇只記錄一些核心的配置，沒什麼價值。

1、單節點部署

Eureka Server 註冊中心服務（運行在環境中jar包）

eureka:
  instance:
    hostname: localhost
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/
  server:
    enable-self-preservation: false #關閉自我保護機制

Eureka Client 生產者，向Eureka Server提供註冊一個服務。

eureka:
  client:
    register-with-eureka: true 
    fetch-registry: true
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/

#register-with-eureka 
#fetch-registry 
#defaultZone

Eureka Consumer到註冊中心消費一個服務

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8080/eureka/

 

2、Eureka Server服務端集羣部署（模擬板）

2-1、添加file:///C:/Windows/System32/drivers/etc/hosts

	127.0.0.1       peer1
	127.0.0.1       peer2


本案例需要起兩個模塊，都是兩jar包

           Eureka-Service                                                         Eureka-Service-Cluster

 

 Eureka-Service 和 Eureka-Service-Cluster 目錄結構是一樣的，Eureka-Service調用的是peer1的配置，而Eureka-Service-Cluster調用的是peer2的配置，實際上就是所謂的互相註冊。

application-peer1.yml

server:
  port: 8080

spring:
  application:
    name: Eureka-Server

eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://mrbird:123456@peer2:8081/eureka/
  server:
    enable-self-preservation: false

application-peer2.yml

server:
  port: 8081

spring:
  application:
    name: Eureka-Server-Cluster

eureka:
  instance:
    hostname: peer2
  client:
    serviceUrl:
      defaultZone: http://mrbird:123456@peer1:8080/eureka/
  server:
    enable-self-preservation: false
