PHP：运行shell_exec或系统作为sudo？

Question

I have a few commands I need to invoke from my PHP web application that can only run as sudo.

http://php.net/manual/en/function.shell-exec.php says (in the comments) that I can do the following:

system('echo <password> | sudo -u root -S <command>');

It doesn't work. I'm trying to do a groupadd, useradd, etc. Suggestions?

To add a user to the sudo list and have it not prompt for a password for a certain program... edit your /etc/sudoers file as such:

Cmnd_Alias BUNDLE = /usr/bin/bundle

deploy  ALL=(ALL) NOPASSWD:BUNDLE

Where deploy is the username and /usr/bin/bundle is the path the program that I want to access without password.
