Running sudo root commands in php
edit the sudoers file (vi /etc/sudoers) and then under "#User priviligie specification" (where it should have root ALL=(ALL:ALL) ALL) add:
www-data ALL=NOPASSWD: path_to_command
example for chown:
www-data ALL=NOPASSWD: /bin/chown
then inside php run using:
exec("sudo -u root command);
example for chown:
exec("sudo -u root chown -R www-data /directory");This is particular usefull if you are trying to edit/delete a file/folder that is owned by root through php. Meaning solution for:
unlink Permission denied
