前言

基于上一篇文章搭建Eureka集群服务
实现3个eureka server节点数据同步
记录搭建过程中的的问题及疑问

Spring Cloud Eureka使用手册
 Eureka Wiki

Eureka集群架构

Eureka高级架构图

紧接上篇的demo项目，在其中新建dingsu-eureka-cluster模块
目标是上图中，3个eureka Server之间的数据同步
项目结构如下图

准备工作

因为是在本机模拟三个eureka Server，修改C:\Windows\System32\drivers\etc\hosts，增加3个域名对应到本地IP(复制到其他路径，右键属性取消只读，修改后复制回去覆盖)

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host

# localhost name resolution is handled within DNS itself.
#	127.0.0.1       localhost
#	::1             localhost
127.0.0.1       activate.navicat.com
127.0.0.1		eureka-server-1
127.0.0.1		eureka-server-2
127.0.0.1		eureka-server-3
