If you want to use multiple users to upload to the same directory the best way to do that is to manage it through groups.

You can all add them to the same group and set the directory to group writeable and then set the .umask to also automatically set each file that is uploaded to group writeable as well.

That way all of the users that upload there can all edit/delete each other's files.

The problem is i have them apart of www-data but they still can't upload, www-data also has ownership of all the files.

Does it have group write permissions enabled as well?

775

Should be the permissions on the directories and the files need:

# chmod -R g+w *

In the directory where you are uploading to.

I'm having the same issue as well.

AH! how did i not notice that! thank you! i used

# sudo chmod -R 775 /var/www/

thank you!

dont forget to umask or stickybit the parent directory as raiyu mentioned. this will avoid future problems where users upload files and the file owner and the group becomes the user and no one else will be able to edit them. umasking will make sure the newly created files will get the www-data as their group.

I'm fairly new to this
isn't
chown -R user:group usr/share/nginx/www
chmod -R 775 usr/share/nginx/www

enough?

By default when a file is created only the "owner" not the group has write permissions.

If you have multiple users sharing a directory then each user that uploads a file will be the only owner of it so other members of that group will be unable to edit or delete that file.

That is why you setup the umask for the directory which will automatically make each file that is created there writeable by both the owner and the group. Then any other user in the group can delete another user's file or update it.

It really depends on whether or not you want to allow that.

Well at least in my case I'm developing locally. my www directory is set to owner and group being root.
I'm going to change it to www-data like in Apache and I'm going to add my user to the www-data group :P

how do you unmark stuff in linux? :S
I'm fairly new to this :S

If I'm not mistaken just goto the directory where you want to set it and do:

# umask 022

And you should be all set so that all new files created will be group writeable.

I created a symbolic link to /var/www/ to the home folder of the website. I only host one domain though. If I had more than one domain I would have to go the Virtual Host route.

Got a similar issue. I use winscp. I can add, delete and modify files and folders with my non-root user but any new files or folders I create/upload I cannot change ownership from my non-root user to www-data, I get permission denied. I have always have to open a terminal to chown which is a bit of a pain. Any way around this?

@p_ingram3541: Run

sudo chgrp www-data /path/to/dir

sudo chmod g+s /path/to/dir

cd /path/to/dir

sudo umask 002

Does that fix it?

I'm having the same issue and haven't been able to resolve it using any suggestions here or elsewhere. My user is part of the admin and www-data groups and /var/www/* is all owned by www-data, but I can't upload or modify anything. Logging in as root works, but I'd like to avoid that.

If it matters, I'm using Transmit, the Mac GUI.
