Linux Ubuntu 14.04.1 File Permissions

Question

im really new to Linux permissions so I would appreciate help with this simple query.

Ubuntu 14.04.1

I have 2 users root and user1

I have a directory /var/www/html/gallery

The directory is empty

I would like to create a new group add root and user1 to that group and make that group have read, write and delete permissions (FULL PERMISSIONS), to the directory, /var/www/html/gallery

Can someone please help me ?

Thank you.

Answer 1

Root is usually not added to any group because root is allowed to do everything he or she wants.

So you have multiple options now:

1) you don't create a group and give the permissons to user1 (simplest solution)

chown -R user1:user1 /var/www/html/gallery

chmod -R 700 /var/www/html/gallery

2) you create the group anyways and just add one user. that just makes sense when you want to add some more users to the group later

Answer 2

you can use acl for permissions,

sudo apt-get install acl

sudo groupadd connoisseurs

sudo usermod -a -G connoisseurs Teddy

sudo setfacl -m g:connoisseurs:rwx /var/www/html/gallery

you can vary permissions with r,w,x combinations.
