PHP Question
Phpseclib SSH2 not executing Shell Scripts
Currently trying to create a PHP web application to run a variety of Shell Scripts to handle website generation and cleanup on delete.
Here's a snippet from my deletePropertyProcess.php:
$ssh = new Net_SSH2($server);
if(!$ssh->login("username", "password")) {
$result['result'] = 'ERROR';
$result['message'] = 'Login failed to server ' . $server;
} else {
$result = $ssh->exec("cd /var/www/sites ; sudo /usr/local/bin/delete_property_folder.sh -c $comp -p $prop");
echo $result;
}
Where
delete_property_folder.sh-c $comp -p $propThe fun part is, all of this works flawlessly via Putty. Running this functionality from PHP via Ajax returns the exit status of the Shell Script and the anticipated output from Ajax, but none of the changes handled by my Shell Script are actually applied.
Like I said, this runs perfectly from Putty so I doubt the issue is the Shell Script but here it is anyways:
#!/bin/bash
function fix_file_permissions() {
chown -Rf username:username $1/$2
echo $?;
}
function delete_specified_folder() {
rm -rf $1/$2
echo $?;
}
##Main Script Body
POSITIONAL=()
while [[ $# -gt 0 ]]
do
key="$1"
case $key in
-c|--company)
COMPANY="$2"
shift
shift
;;
-p|--property)
PROPERTY="$2"
shift
shift
;;
*) #unknown option
POSITIONAL+=("$1") #save it in an array for later
shift
;;
esac
done
set -- "${POSITIONAL[@]}" #restore positional parameters
PERMISSIONS_FIXED=$(fix_file_permissions $COMPANY $PROPERTY)
if [ $PERMISSIONS_FIXED -eq 0 ]; then
FOLDER_DELETED=$(delete_specified_folder $COMPANY $PROPERTY)
echo $FOLDER_DELETED
exit
fi
echo 1
At this point, any recommendations would be useful. Let me know if you need any more information.

I've managed to get it working by feeding the sudo password via --STDIN to the Shell Script's full path using the following:
$result = $ssh->exec("cd /var/www/sites; echo 'password' | sudo -S /usr/local/bin/delete_property_folder.sh -c $comp -p $prop");
echo-ing your password with sudo -S allows you to pass your password via the pipe into the sudo shell script execution.
