User Permissions: Daemon and User

I often run into this issue on Linux, and I'd love to know the proper way of solving it.

Say I have a daemon running. In my example, I'll use LigHTTPD, a webserver.

Some software, like Wordpress, enjoys having read/write access to files for updating applications via a web interface, which I think is quite handy.

At the same time, I enjoy being able to hack on my files using vim, using my local user account, 'eddie'.

Herein lies the rub. Either I chown everything to lighttpd or eddie and a shared group between them both, and chmod it 660, or perpetually sudo to edit the damned things. The former isn't a bad solution, until I create a new file in which case I have to remember to chmod it appropriately, or create some hack like a cron job that chmods for me.

Is there an easier way of doing this? Have I overlooked something?

Cheers,

Solution 1:

In fact there is a way to auto-chown files created in a certain directory. Let's say the files you want lighttpd to be able to access are in /var/www. Then you set the group of /var/www to your group and set the SGID bit on /var/www. You will probably want to do this recursively for subdirs. I'm assuming the group is www-data.

chgrp -R www-data /var/www
chmod -R g+s /var/www

This will just set the group however. To give newly created files 660 permissions by default you can set your umask to 007. Add this line to ~/.bashrc:

umask 007
