mount one directory to another while mapping the original directory's UID to another

Question

I'd like to mount the directory /var/www/mysite to the directory /home/daniel/mysite, but also have the user of the mounted files mapped from the original user (www-data) to my own user (daniel).

So that the file /var/www/mysite/index.php who's user is www-data will appear in the mounted directory as /home/daniel/mysite/index.php and be owned by daniel - and alternatively, if I create a file /home/daniel/mysite/test.php with my own user, it will be created in the original directory under the user www-data

Is it possible? If not, what alternatives do I have so I can use an IDE and still make sure all the files belong to the HTTP server's user?

Answer 1

The simplest solution would be to create a symbolic link using ln -s to the mysite folder under your home drive after granting yourself write access to everything under the mysite folder.

Answer 2

I ended up using NFS to solve my conundrum. I used this tutorial as a base and ended up having the following in /etc/exports:

/var/www/mysite localhost(rw,sync,no_subtree_check,all_squash,anonuid=33,anongid=33)

(all in a single line; where 33 is www-data's UID and GID)

and the following in /etc/fstab:

localhost:/var/www/mysite /home/daniel/mysite nfs4 defaults 0 0

When I browse the directory it says every file belongs to www-data:www-data, but I can create and edit files as if they belonged to my own user.
