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 :

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);
}
}
