看一下有哪些資源
crm resource status
 刪除 ms_drbd_mysql  資源
crm resource stop ms_drbd_mysql ; crm configure delete ms_drbd_mysql

[root@DRBD01 ~]# cat /etc/drbd.d/r0.res

第一行 : 找現行目錄為 *.c 的檔案

先　SET HOSET &SSH 交換金鑰

日期的offset =OFFSET(data!$A$2,COUNTA(data!$A:$A)-1-data!$J$1,1,data!$J$1,1)
DATE 是參照前一個$A的欄位去統計的其長度為 $J$1 設定的大小(由資料的最後一筆計算)
 

近來有程式背景安裝微軟修補程式，之前與北京微軟合作時有用過，備份起來怕忘記了。
 
一、Microsoft Windows Installer
若某個軟體是用 Windows Installer 封裝的，那您就應該能在資料夾中看到 *.msi 檔案。這是最典型的特徵，這些檔案通常可以使用 /qb 和 /qn 參數進行自動安裝。
/qb 會在視窗中顯示一個基本的安裝行程。
/qn 參數則不會顯示任何視窗，直接在背景自動安裝。
