apache-user & root access
- by ahmedshaikhm
I want to develop few scripts in php that will invoke following commands; using exec() function
service network restart
crontab -u root /xyz/abc/fjs/crontab
etc.
The issue is that Apache executes script as apache user (I am on CentOS 5), regardless of adding apache into wheel or doing good, the bad and the ugly group assignment does not run commands (as mentioned above).
Following are my configurations;
My /etc/sudoers
root ALL=(ALL) ALL
apache ALL=(ALL) NOPASSWD: ALL
%wheel ALL=(ALL) ALL
%wheel ALL=(ALL) NOPASSWD: ALL
As I've tried couple of combination with sudoer & httpd.conf, the recent httpd.conf look something as follows;
my httpd.conf
User apache
Group wheel
my PHP script
exec("service network start", $a);
print_r($a);
exec("sudo -u root service network start", $a);
print_r($a);
Output
Array
(
[0] => Bringing up loopback interface: [FAILED]
[1] => Bringing up interface eth0: [FAILED]
[2] => Bringing up interface eth0_1: [FAILED]
[3] => Bringing up interface eth1: [FAILED]
)

Without any surprise, when I invoke restart network services via ssh, using similar user like apache, the command successfully executes. Its all about accessing such commands via HTTP Protocol. I am sure cPanel/Plesk kind of software do use something like sudoer or something and what I am trying to do is basically possible. But I need your help to understand which piece I am missing?
Thanks a lot!
