How Can I Run Sudo-Protected Shell Scripts from PHP Without a Password Prompt?

Running sudo-Protected Shell Scripts from PHP

When attempting to execute shell scripts requiring sudo privileges from PHP, users often encounter the issue of being prompted for a password in the absence of a command line prompt like the one used to run sudo manually. This article addresses this challenge by exploring a solution that allows for passwordless sudo execution from within PHP.

Leveraging the sudoers File

To resolve this issue, we can modify the sudoers file using the visudo editor. The following steps outline the process:

sudo visudo

Once in the editor, add a rule to the file that permits the web server user to execute the script without a password prompt. The rule should take the following format:

www-data ALL=NOPASSWD: /path/to/script

In this rule, "www-data" represents the web server user, "ALL" allows the user to execute any command, "NOPASSWD" eliminates the need for a password, and "/path/to/script" specifies the script that can be run without a password.

By adding this rule to the sudoers file, the web server user is granted the necessary permissions to execute the sudo-protected shell script from PHP without entering a password.
