WIN2016故障轉移群集

準備工作：

主機名

域名

WINA

192.168.0.24

WINA.NET

WINB

192.168.0.25

WINB.NET

WINC

192.168.0.26

WINC.NET

所有主機配置主機信息修改好主機名IP DNS為本機IP （以單臺主機A為例）

互相ping測試連通性（以單臺主機A為例）

所有主機安裝角色功能 DNS和故障轉移群集（以單臺主機A為例）

所有主機配置DNS解析記錄并測試解析

新建正向查找區域NET

新建反向查找區域

新建正向查找區域記錄默認已生成本機記錄

新建反向查找記錄（我們新建正向記錄勾選了PTR指針默認已經新建了B/C主機的反向記錄）現在只需新建一條本機的PTR記錄

測試解析

A主機配置故障轉移群集 B/C主機連接到群集指定虛擬IP192.168.0.88

主機A創建群集TEST

主機B/C連接到群集TEST

主機B（192.168.0.25）

查看群集當前在用主機為哪臺（網卡應有88IP）

所有主機安裝IIS 80端口為默認網頁訪問測試

關閉掉在用主機(網卡有88的主機同時只會有一臺) 查看在用主機被選為了哪臺 192.168.0.88:80是否還可以打開（使用網絡中其他主機來打開網頁）

關閉掉A主機后 B主機擁有了88IP 網頁依然可以打開

繼續關閉B主機

此時C主機擁有了88IP 網頁依然可以打開

參考：

注：

經后期測試建議不要將群集所有主機全部宕機否則會出現問題

進階：

以上內容為群集搭建及群集中某主機宕機后恢復業務的情況

下面記錄一種主機沒有宕機 IIS站點掛掉無法提供服務的情況

新建文本文檔修改為IIS.vbs 內容如下（虛線內內容）注意修改網站和應用程序池名稱(默認無需修改)
