# 客户端服务实例id相同，被顶掉测试，服务被覆盖。 #

相同的服务，不同的名字，点开链接相同

如果所示，为不同名称的同一个服务，最新注册的服务为

**UP** (1) - [192.168.0.151:SERVICE-C1][192.168.0.151_SERVICE-C1]

所以先删除curl -X DELETE http://224:224@localhost:8888/eureka/apps/SERVICE-C1/192.168.0.151:SERVICE-C1:4444 发现只剩下192.168.0.151:SERVICE-C1服务了。

并且已经删除的服务因为服务名不会再通过心跳注册，所以，再也不会进入up状态。

再次查看注册中心，服务的确被删除了。过了一会儿，因为心跳的机制的存在，服务会自动注册上。

# 新增服务 #

curl -X PUT “http://224:224@localhost:8888/eureka/apps/SERVICE-C1/192.168.0.151:SERVICE-C1:4444/stauts?value=UP”

对于一个位置的instanceid，服务将不会出现在列表里。

[192.168.0.151_SERVICE-C1]: http://192.168.0.151:4444/info
