spring cloud之 EurekaServer

只是为了整理代码
(1) pom.xml

(2) 配置

server:
  port: 8761
  # Redis数据库索引（默认为0）
eureka:
  instance:
    hostname: eureka-server
    prefer-ip-address: true
  client:
    registerWithEureka: false
    fetchRegistry: false
    service-url:
      defaultZone: http://localhost:8761/eureka/

spring:
  application:
    name: tdcloudserver

(3) Application

@EnableEurekaServer
@SpringBootApplication
public class TDGISEurakaServer {
    public static void main(String[] args) {
        SpringApplication.run(TDGISEurakaServer.class, args);
    }
}

(4) 高可用Eureka Server 集群 处理体量比较大的微服务集群
4.1 需要修改application.yml 配置，在配置中采用profile的格式

 ---
 server:
      port: 8761
      # Redis数据库索引（默认为0）
    eureka:
      instance:
        hostname:peer1
      client:
        service-url:
          defaultZone: http://peer1:8761/eureka/
    spring:
      profiles:peer1
      ----
    server:
  			port: 8762
 	eureka:
  		instance:
    		hostname: peer2
 	client:
		service-url:
      		defaultZone: http://peer2:8762/eureka/
  	spring:
      	profiles:peer2

4.2 修改hosts 文件 添加 127.0.0.1 peer1 127.0.0.1 peer2
4.3 启动jar 配置 spring.profiles.active=peer1 spring.profiles.active=peer2
