shell-script-php execution of Shell scripting issues

1. I wrote a PHP script to execute some shell scripts through the Web interface.

The 2.shell script will use sudo

3.sudo user has set the Nopassword

4. Manually in the nobody User environment, (su-s/bin/bash nobody), and then execute the shell script can be executed normally, but through PHP execution, sudo that statement will not execute

How do I use PHP? This is currently performed using the Shell_exec function.

Know the reason, yes, sudo:sorry, you must has a TTY to run sudo

The system configuration can be modified.

This is a relatively dangerous way .... First of all, no matter how to achieve ...
sudo you need sudo to open the PHP process so PHP is doing sudo.

Add the WWW user to the root group

The 2.shell script will use sudo

This means that the execution of the shell script requires sudo permission?

It seems that this is a very dangerous operation Ah, cautious and cautious.

Of course, non-execution is generally caused by permissions issues. Execute PHP script in webserver environment, take Nginx as an example, generally use WWW user, you can under the CLI, if based on your request, first www should belong root group .
Second, for ease of debugging, you can try the CLI

sudo -Hu www php your.php

Also, the shell_exec function returns a value, that is, the shell's output, err_log() to the file to see the chant.

PHP can only execute part of the command, which is the same with root.
