EC2实例的文件权限

Question

I keep getting this issue on EC2. I've a cron that is run by root user. Whenever this tries to access files (fopen in read-only or filesize) in a folder that has 777, it fails with an error similar to "Warning: filesize(): stat failed for /var/www/.."

It is becoming increasingly difficult to predict this behaviour. Has anyone faced similar issues? Or any recommended way of setting up users and groups? I'm running it on a default setup. Safe mode is turned off as well.

Added my comment as an answer :

If the cron job is run by root then it's not a permissions issue (root has access to any file). This error is usually issued when the file doesn't exist.
