关闭掉在用主机(网卡有88的主机 同时只会有一台)  查看在用主机被选为了哪台 192.168.0.88:80是否还可以打开 (使用网络中其他主机来打开网页)

关闭掉a主机后 b主机拥有了88ip 网页依然可以打开

经后期测试 建议不要将群集所有主机全部宕机 否则会出现问题

此时我们在群集下角色列表里可以看到iis故障转移群集角色

WINDOWS2016故障转移群集(图文教程)

查看一下winc(192.168.0.26)主机的网卡情况

WINDOWS2016故障转移群集(图文教程)

测试访问http://192.168.0.99  --------  可以打开

WINDOWS2016故障转移群集(图文教程)

现在我们模拟winc主机iis网页服务挂掉/端口无法访问 打开winc主机iis管理器 展开网页 停止默认网站

WINDOWS2016故障转移群集(图文教程)

再次打开浏览器 打开http://192.168.0.99  ----- 依然可以打开

WINDOWS2016故障转移群集(图文教程)

主机a上查看群集角色 已经自动切换到winb提供web服务

WINDOWS2016故障转移群集(图文教程)

查看winb主机网卡信息   99ip已自动切换到winb 我们打开的是winb的网页

WINDOWS2016故障转移群集(图文教程)

同理 我们关闭winb的iis网站 99又会切换到wina 访问依然不受影响

WINDOWS2016故障转移群集(图文教程)

至此 我们实现了 主机在非宕机情况下 iis站点挂掉后切换主机提供服务的情况

注:

1、本测试中99ip对应的不是整个iis服务 只是一个站点(默认站点)

2、用户上传的附件需要一个群集共用的存储介质 目前还未解决 待完善
