基于SpringCloud Eureka 搭建服务注册中心

新建一个springboot项目:eureka-server

添加Maven依赖信息 :

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>

application.yml配置:

spring:
  application:
    name: eureka
server:
  port: 8761
eureka:
  client:
    service-url:
      defaultzone: http://127.0.0.1:8762/eureka/
      #eureka必须实现高可用至少2个 2个eureka是互相注册 3个eureka则是两两互相注册
      #defaultzone: http://127.0.0.1:8761/eureka/ 即1注册到2 2注册到1
      #defaultzone: http://127.0.0.1:8761/eureka/,http://127.0.0.1:8762/eureka/
      #即 启动1时 将1注册到2和3 启动2时 将2注册到1和3  启动3时 将3注册到1和2
    register-with-eureka: false #本身就是一个注册中心所以不需要自己注册进eureka
  server:
    enable-self-preservation: false #eureka server 的自我保护 开发环境关闭 生产环境打开

在启动类中进行配置@EnableEurekaServer配置

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