运行需要通过PHP进行root访问的程序

Question

I'm searching to execute a program via PHP, but it needs roots access, because it's accessing hardware stuff.

Is it possible to allow the www-data user to execute some programs and access some devices ?

Is it really not safe to add www-data in sudo group ?

Answer 1

I think changing script owner to www-data will make your script executable.

In Linux, use chown to change script owner

chown www-data file.txt

This will change file.txt owner to www-data

chown -R www-data /files/work

Recursively grant ownership of the directory /files/work, and all files and subdirectories, to user www-data.

In PHP, you can use chown function to change ownership

<?php

// File name and username to use
$file_name= "foo.php";
$path = "/home/sites/php.net/public_html/sandbox/" . $file_name ;
$user_name = "root";

// Set the user
chown($path, $user_name);

// Check the result
$stat = stat($path);
print_r(posix_getpwuid($stat['uid']));

?>
