sudo [ no tty present and no askpass program specified ] [ can't stat /var/run/sudo: Permission denied ]

Question

I'm running rsync from a php script using backtick operators. It's running as an apache user.

In /etc/sudoers, I've set

#Defaults requiretty Cmnd_Alias REPORTS = /usr/bin/rsync apache ALL = NOPASSWD: REPORTS 

In the error log, I'm getting these errors

sudo: can't stat /var/run/sudo: Permission denied sudo: no tty present and no askpass program specified 

Also, not that the rsync path is correct, and so is the rsync command in php. I can run the command as root, also if I add NOPASSWD to another user, i can sudo and run the same command.

Answer 1

This is likely because sudo requires a TTY session to run. You can force sudo to assume/use a TTY by passing in the -t arguments, i.e.:

sudo -tt /usr/bin/rsync 

Answer 2

Disable SELINUX(/etc/selinux/config SELINUX=disabled and reboot).
