Allow a user write access to /var/www - what's the best approach

[SHRIKEE]

So i'm wondering, i've got a Ubuntu 8 server set up. LAMP, and it works fine so far.

Now i'm at the point of putting a bunch of files to work on /var/www in order to run a small website.

Turns out my user (arnan) has read only rights on /var/www
root is forbidden in sftp.

I prefer to use sftp. And am not aware of any installed FTP servers.

Now i can just go into the openssh config and allow root access. Or i can do some magic with userrights and change ownership on /var/www to my user.

I'm wondering what would be the best approach.

I use a mac and use Cyberduck as my FTP client. This allows me to use FTP SFTP and SSH/SSL.
I prefer SFTP.

Please advise!

Thanks!

The best approach would be to change the user/group rights. Allowing root probably isn't the best idea, especially when you could change the folder to owned by the group as www-data and make your user a member of that group and give the group folder write access (and sub-folders). That's my 2 cents

In support of the crazycaveman I would also make the changes recommended here. Using setgid and umask together ensure that everyone belonging to that group will have write access to the files.

I agree with crazycaveman as well...

Make sure the group is www-data on '/var/www'.

prompt> sudo chgrp www-data /var/www

Make '/var/www' writable for the group.

prompt> sudo chmod 775 /var/www

Set the GID for www-data for all sub-folders.

prompt> sudo chmod g+s /var/www

Your directory should look like this on an 'ls -l' output.

drwxrwsr-x

Last, add your user name to the www-data group (secondary group).

prompt> sudo useradd -G www-data [USERNAME]

You should now be able to SFTP to your server as your user name and upload to '/var/www' with no problems.

An alternative is simply to move the default Apache site elsewhere - see https://help.ubuntu.com/community/Ap...irtual%20Hosts

Thanks all for your kind, prompt and clear answers. I followed Killahurtz's instructions and got the following:

I then logged in with my user 'arnan' via SFTP and tried to upload a file to the /var/www but i still got the permission denied thing.

I'm guessing folder ownership should remain root? Or should i change that too?

Thanks!

This worked perfectly for me, thanks !
