1. Concept: Eureka-Cloud service discovery, a REST-based service for locating services to enable mid-cloud service discovery and failover.

2, Build: A, first of all, the next stand-alone construction, the first new MAVEN project, in the POM import Eureka coordinates:












B, New class Eurekaapplication



public class Eurekaapplication {

public static void Main (string[] args) {

Springapplication.run (Eurekaapplication.class, args);



Where @enableeurekaserver, start a service registry to provide conversations for other apps

C, application.properties configuration items

# The default port server.port=8761




D, start springboot, and Access http://localhost:8761/

3, the above is only a single-machine mode environment, the business environment is often high-availability (HA) environment, this time to consider the cluster, a node hangs, there is another node, cluster we just change the configuration file can be

eureka.client.serviceurl.defaultzone=http://localhost:8762/eureka/;http://localhost:8763/eureka/; If IP is different, configure three nodes , you need three machines
