SpringCloud填坑⽇志（2）——多个EurekaServer节点启动报错
问题描述：
建⽴了⼀个microrvice-discovery-eureka-ha的项⽬，实现Eureka运⾏多个实例并相互注册的⽅式实现⾼可⽤部署，配置⽂件
spring:
application:
name: microrvice-discovery-eureka-ha
---
spring:
# 指定profile=peer1
profiles: peer1
rver:
port: 8761
eureka:
instance:
# 指定当profile=peer1时，主机名是peer1
hostname: peer1
client:
rviceUrl:thereafter
# 将⾃⼰注册到peer2这个Eureka上⾯去
defaultZone: peer2:8762/eureka/
---
spring:
profiles: peer2
rver:
port: 8762
eureka:
instance:
hostname: peer2
client:
rviceUrl:
defaultZone: peer1:8761/eureka/
打包项⽬后，在项⽬对应的target⽂件夹使⽤以下命令启动两个Eureka Server节点：
java -jar microrvice-discovery-eureka-ha-0.0.1-SNAPSHOT.jar --spring.profiles.active=peer1
java -jar microrvice-discovery-eureka-ha-0.0.1-SNAPSHOT.jar --spring.profiles.active=peer2
报错摘要：
There was a problem with the instance info replicator
Cannot execute request on any known rver eureka rver
两个节点的详细错误：

问题出现原因：
仔细分析报错，是由于找不到Eureka Server的可⽤的Replicator造成的，但是为什么会找不到呢？思索发现，是由于⾃⼰没有同时启动Eureka Server的两个实例，所以在启动⼀个实例的时候找不到另外实例。
解决⽅法：
开启两个CMD窗⼝按照以上java -jar jar包名称命令同时运⾏以上两个实例。
