這篇文章跟大家分析一下“WINDOWS2016故障轉移的示例分析”。內容詳細易懂，對“WINDOWS2016故障轉移的示例分析”感興趣的朋友可以跟著小編的思路慢慢深入來閱讀一下，希望閱讀后能夠對大家有所幫助。下面跟著小編一起深入學習“WINDOWS2016故障轉移的示例分析”的知識吧。
WIN2016故障轉移群集
準備工作：
主機名 | IP | 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

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)

'<end script sample>將文件復制到所有群集主機的相同目錄下 如：C:\Windows\System32\inetsrv主機A打開故障轉移群集管理器 連接到群集TEST
配置IIS故障轉移
此時我們在群集下角色列表里可以看到IIS故障轉移群集角色
查看一下WINC（192.168.0.26）主機的網卡情況
測試訪問http://192.168.0.99 -------- 可以打開
現在我們模擬WINC主機IIS網頁服務掛掉/端口無法訪問 打開WINC主機IIS管理器 展開網頁 停止默認網站
再次打開瀏覽器 打開http://192.168.0.99 ----- 依然可以打開
主機A上查看群集角色 已經自動切換到WINB提供web服務
查看WINB主機網卡信息 99IP已自動切換到WINB 我們打開的是WINB的網頁
同理 我們關閉WINB的IIS網站 99又會切換到WINA 訪問依然不受影響
至此 我們實現了 主機在非宕機情況下 IIS站點掛掉后切換主機提供服務的情況
注：
1、本測試中99IP對應的不是整個IIS服務 只是一個站點（默認站點）
2、用戶上傳的附件需要一個群集共用的存儲介質 目前還未解決 待完善
