主机
修改hosts 模拟两台主机
C:\Windows\System32\drivers\etc\hosts
# Copyright (c) 1993-1999 Microsoft Corp.
#
# 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:
127.0.0.1 localhost
127.0.0.1 www.galsang.org
127.0.0.1 www.galsang.io
服务注册中心
一台机器模拟出的两台主机规划如下：
| 项目名称 | spring.application.name | eureka.client.serviceUrl.defaultZone | eureka.instance.hostname | 端口 |
|---|---|---|---|---|
| spring-cloud-server | spring-cloud-server-discovery-eureka-ha | http://www.galsang.io:8999/eureka/ | www.galsang.org | 9000 |
| spring-cloud-server-available | spring-cloud-server-discovery-eureka-ha | http://www.galsang.org:9000/eureka/ | www.galsang.io | 8999 |
