execution of ssh in python script which is called from php exec command
Question
I have a PHP code which calls a python script.In python script i am connecting to a remote system using ssh and running a command.When python code is executed independently all seems perfect,but when i call it from php, the connection can't be established and it prints an empty string as output in the browser.
Here is my php script
<?php
$command = escapeshellcmd('python p.py');
$output = shell_exec($command);
echo $output;
?>
Python script(p.py) is as follows
import subprocess
proc = subprocess.Popen(["ssh remotehost uptime"], stdout=subprocess.PIPE, shell=True)
(out, err) = proc.communicate()
print "program output:", out
When I execute
python p.py
the program successfully prints the result.And when the php script is executed the browser just displays
program output:
which shows python script gets executed and the problem is in ssh connection when called through php. can anyone suggest me a way to make it work properly?
EDIT:
when my python code has database connections ,similar issues araised . After surfing i found that in /etc/sysconfig I have to give
setsebool -P httpd_can_network_connect_db=1
Is there any similar issues that should be considered for connections over ssh??

Try using this code in your php code. Note : the file should have a .php extension.
<html>
<head></head>
<body>
<H3>Executing...</H3>
<?php exec("p.py"); ?>
<H3>Completed...</H3>
</body>
</html>
