Permissions for Upload Folder in PHP/Apache
In this context, the user seeks guidance on setting appropriate file permissions for an upload folder within a PHP/Apache environment. The goal is to allow successful file uploads and subsequent modifications for both the webserver user and an FTP user.
To address this challenge, it is essential to understand the interplay between file permissions, ownership, and user groups.
Ownership and File Permissions
The initial approach of setting the upload folder's ownership to the webserver user (apache) and permissions to 755 restricts writing access to that user only. This explains the difficulty in modifying uploaded files by the FTP user.
Addressing the Permissions Issue
To resolve this limitation, consider creating a customized group. Additionally, grant both the webserver user (apache) and FTP user membership in this group. Subsequently, assign file permissions of 775 to the upload folder. This combination allows write access for both the webserver and FTP users while restricting modifications to others.
By implementing this approach, you can ensure both successful file uploads and the ability of authorized users to modify files within the upload folder, addressing the initial concern.
