使用来自网页的php在root下执行/运行可执行文件

Question

I want to run a executable file on my server when a user clicks a button on webpage. I am able to run the executable using exec command but the program runs under 'nobody' even if I followed the instructions in post : How to run from PHP a bash script under root user answer by : Riateche

But still the execuable file runs under 'nobody'

My executable program is kept in directory

/opt/lampp/htdocs/project

My php code

<?
$variable = 10;
$site_dir = 'project';
echo "<img src ='".exec('/opt/lampp/htdocs/' . $site_dir .'/myProgram '.' '.$_GET['value1'] .' '. $variable )."'>";
?>

Answer 1

You are not using the sudo keyword before your command:

echo "<img src ='".exec('/opt/lampp/htdocs/' . $site_dir .'/myProgram '.' '.$_GET['value1'] .' '. $variable )."'>";

Should be:

echo "<img src ='".exec('sudo /opt/lampp/htdocs/' . $site_dir .'/myProgram '.' '.$_GET['value1'] .' '. $variable )."'>";
