問題簡述：在oracle linux下安裝oracle10g，多個文件報“Permission denied”錯誤，無法啓動圖形界面，下面是執行並逐步解決的過程。
[oracle@ocmu software]$ cd database/
[oracle@ocmu database]$ ls
doc install response runInstaller stage welcome.html
[oracle@ocmu database]$
開始執行oracle的安裝，忽略對操作系統的認證，報沒有權限執行
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs
bash: ./runInstaller: Permission denied
[oracle@ocmu database]$
[oracle@ocmu database]$
檢查一下發現確實沒有執行權限
[oracle@ocmu database]$ ll
total 28
drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 doc
drwxr-xr-x 5 oracle oinstall 4096 Jul 2 2005 install

drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 stage
-rw-r–r– 1 oracle oinstall 5100 Jul 2 2005 welcome.html
授予755 的權限
[oracle@ocmu database]$ chmod 755 runInstaller
[oracle@ocmu database]$ ll

drwxr-xr-x 9 oracle oinstall 4096 Jul 2 2005 doc

-rw-r–r– 1 oracle oinstall 5100 Jul 2 2005 welcome.html
[oracle@ocmu database]$
再次執行oracle安裝，提示/software/database/install/.oui這個隱藏文件沒有執行的權限
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs
./runInstaller: line 52: /software/database/install/.oui: Permission denied
cd到指定目錄，查看一下，確認沒有後，給予755 權限
[oracle@ocmu database]$ cd install/
[oracle@ocmu install]$ ll

回到執行安裝目錄，三次執行安裝，發現有些靠譜了，但是，圖形界面還是沒有出來，下面還是報錯，本次是“/software/database/install/unzip: Permission denied”
[oracle@ocmu install]$ cd ..
[oracle@ocmu database]$
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs

cd到unzip指定目錄，賦755

回來，四次執行安裝oracle命令，還好，此時，可以正常啓動圖形界面開始安裝了。
[oracle@ocmu install]$ cd ..
[oracle@ocmu database]$
[oracle@ocmu database]$ ./runInstaller -ignoresysprereqs
真怕安裝到半路還有問題，忐忐忑忑的裝成功了。
小結：
爲什麼那三個文件沒有執行權限，它們是怎麼導致沒有執行權限的呢？
因爲，在軟件上傳到linux服務器之前，由於linux服務器的空間緊張，所以就在windows環境下將其先解壓，然後再上傳的，上傳時，已經是解壓後的文件夾了，故導致那三個文件的執行權限丟失。
