Linux – How to make new files automatically belong to group

centoschgrplinuxPHPwebsite

I have used chgrp for the 'logs' and 'cache' directories, and chmod 770, so both the linux user asigned to that site (used to execute scripts from the command-line), and the user 'apache' can read/write log and cache files (because both users belong to the group of that site).

The problem is that when one of them creates a file, the other one is not able to write or delete it. The file is being created as owned by its creator, but not belonging to the group. I thought using chgrp in the parent directory was the solution.

Any ideas?

PS: I'm on Centos 5.5, and PHP 5.3

chmoding a directory setgid (g+s) will make all files created within it inherit group ownership.

Specify default group and permissions for new files in a certain directory

In order to have all files under a given directory inherit group rights, you need to use the setgid bit on your directory. See this link.

 $ mkdir test
 $ sudo chown raphink.staff test
 $ ls -lhd test
     drwxr-xr-x 2 raphink staff 4.0K 2009-12-21 16:19 test
 $ sudo chmod g+s test # Set the setgid bit
 $ ls -lhd test
     drwxr-sr-x 2 raphink staff 4.0K 2009-12-21 16:21 test
 $ touch test/foo
 $ ls -lh test
     total 0
     -rw-r--r-- 1 raphink staff 0 2009-12-21 16:23 foo

Linux – How to force specific permissions for new files/folders on Linux file server

I typically use SAMBA's native functionality for permissions and groups management on shares. For example..

force user=user1
force group=sharedgroup
create mask=775

You would specify these settings under the share. Be certain to reload SAMBA after the configuration change, which could be done via the init script.
