User http does not have write permissions directory?
- by dwieeb
I have a bit of an odd set up, I think. I have groups for each domain my server hosts, and I add the user http to each domain group along with the users that should have access to the groups' domains. In my php script running from a directory 'public_html', I try creating a file:
<?php
$output = "";
print exec('touch test 2>&1', $output);
But I get
touch: cannot touch `test': Permission denied
and the file is not created. But here, clearly stated, the group has all permissions on the directory:
drwxrwxr-x 5 dwieeb example.com 1024 Feb 4 05:19 public_html
And here are the permissions on the php file in public_html that is trying to use the exec function:
-rw-rw-r-- 1 dwieeb example.com 59 Feb 4 05:19 test.php
How is this possible if http is part of the example.com group (as seen from a cat on /etc/group) and the directory has full permissions for the group? ...
example.com:x:1000:dwieeb,http
I'm stumped.
EDIT (since apparently I'm not cool enough to answer my own questions yet):
Ah, I found the problem. Yes, I restarted Nginx, but the php-fpm daemon must be restarted as well when http is added to the group for my domain.
On Arch Linux:
rc.d restart php-fpm
