Why my Server Always Change automatically in Folder Permissions?

Question

我有一个带有WHM / cPanel的centOS服务器，但是我的服务器有问题，有时候文件夹权限会自动更改，如果上传图片后带有网站文件夹变成755，那么在上传之前该文件夹是777 ...谢谢。

Answer 1

Upload means you perform an upload with a user to it's home directory and if the user and group of that directory is you only then for /home the umask value is 002 and if you upload a folder and you belong to a common group which is used by other users too the umask value for /home becomes to 022 so it makes the dir/folder permission as 755. So which user you are trying to upload that matters, upload with a user & group which are equal say janitra is the user and group is also janitra.
