微服务的搭建如何配合idea这个工具将会非常有效率。

创建EurekaServer

正常创建项目就行了

启动器配置：

只是简单的开启配置就行了，但是，千万注意注解是 @EnableEurekaServer，是 Server！！！！

image-20200819144643214

核心配置文件：

想要集群，就必须要eureka的服务端端口相互指向。比如 01服务器端口1 02服务器端口2 ，那么在启动01服务器的时候 defaultZone 就要是2，02服务器启动时 defaultZone 就要是1

这是基本配置

1
2
3
server.port=10086
spring.application.name=eureka
eureka.client.service-url.defaultZone=http://localhost:10087/eureka

这是更改后的配置：

1
2
3
server.port=10087
spring.application.name=eureka
eureka.client.service-url.defaultZone=http://localhost:10086/eureka

启动eureka集群

启动 基本的 springboot 启动器

在启动器编辑中添加新的springboot启动器

先使用基本配置启动

再使用更改后的配置启动

eureka.client.service-url.defaultZone=http://localhost:10086/eureka
eureka.instance.prefer-ip-address=true
eureka.instance.ip-address=localhost
#   applicatonname   是对进入集群后的自己命名
#   defaultZone   指定集群
#   prefer为true就可以将IP注册到Eureka Server上，而如果不配置就是机器的主机名
#   ip-address   为本机的ip
