Question

I want to run some command from a remote server in my php using exec. Like this:

<? php
exec('ssh user@remote_server command');
?>

My account has access to ssh to that remote_server with public/private key but not apache. Note that I don’t have root access to either of the machines. All the answers for Generating SSH keys for 'apache' user need root access.

Answer 1

My recommendation: use phpseclib, a pure PHP SSH implementation. eg.

<?php
include('Net/SSH2.php');

$ssh = new Net_SSH2('www.domain.tld');
if (!$ssh->login('username', 'password')) {
    exit('Login Failed');
}

echo $ssh->exec('pwd');
echo $ssh->exec('ls -la');
?>
