[PHP] php5.3 exec() : output truncate
Hi,
I want to get the list of running processes. also, I call exec() with
ps -A
(ps -A displays almost all processes of all users)
Unfortunatly, the output of ps -A seems incomplete
the test file test.php:
?php
unset($buf);
unset($res);
exec(ps -A, $buf, $res);
for($i=0; $i count($buf); $i++)
{
echo($buf[$i].br);
}
?
If I run the test.php under the context of httpd (from
http://server/test.php), I can see only a subset of running processes
(some processes of user apache)
PID TTY TIME CMD
3207 ? 00:00:00 httpd
3359 ? 00:00:00 httpd
3360 ? 00:00:00 httpd
3361 ? 00:00:00 httpd
3362 ? 00:00:00 httpd
3363 ? 00:00:00 httpd
3364 ? 00:00:00 httpd
3365 ? 00:00:00 httpd
3366 ? 00:00:00 httpd
3569 ? 00:00:00 ps
If I run the same script directly from php (from user apache) , I can
see *all* processes as expected
# sudo -u apache php -f test.php
PID TTY TIME CMDbr
1 ?00:00:01 initbr
2 ?00:00:00 migration/0br
3 ?00:00:00 ksoftirqd/0br
4 ?00:00:00 watchdog/0br
5 ?00:00:00 events/0br
6 ?00:00:00 khelperbr
[...]
Is it a problem with exec() or with ps -A or with ?
any ideas ?

[PHP] [SOLVED] Re: [PHP] php5.3 exec() : output truncate
I found the reason of this issue : SELinux
by defaut, SELinux is enabled on CentOS5.5 = httpd runs with
restricted rights
If I temporary disabled SELinux + restart httpd = ps -A from my
script runs as expected
$ setenforce 0
$ /etc/init.d/httpd restart
