I'm beginning to deal with more than one user on my system (it's a VPS serving some sites) and I need to make sure I understand how group permissions work.
Here's my setup:
I have an account named "admin" .. it's basically the primary account that is used for serving most of the sites that I control myself.
Now, I added a second account named "Ville" as one of my users wants to be able to administer that site.
So, I can do this the easy way and just
chown their domains folder under the
ville user and viola, they have permission to do whatever they need be and so forth.
However, let's say I want to also give the
admin user access to the files (modifying and all) .. how can I put both users into the same group and give them both permission?
I've tried doing: sudo usermod -a -G admin ville
To add the ville into the admin group, but ville still cannot edit files by
admin. Permissions for the primary directory for the
ville user are read/write for both owner and group, and the current group for the files is
ville still can't write into the directory.
So, what should I be doing here to get this right and secure at the same time?
