I am studying Accounting in a university.
Many friends are woundering the reason I am going to study accounting.
I got a pure IT background.
But I wish to study a different things.
I believe studying a different subject can widen my mind.
Moreover, I have taken in an accounting system development.
Now , during the accounting course, I finally know what I was doing during that position.
Perviously, I have faced a serious of permission problems during the uploading files.
I am 100% sure that I have changed everything to 777.
Well, I finally found out SELinux stop Apache to change the file system.
Then I turned SELinux off.
Everything are working fine.
