Authentication error in jenkins on using sudo

问题:

I have sh script in jenkins which has sudo ssh command and I am getting this error

Warning: Identity file key.pem not accessible: Permission denied.
Host key verification failed.
sudo: no tty present and no askpass program specified

I have found solutions saying add

jenkins ALL=(ALL) ALL

these lines in /etc/sudoers but still its not working.

回答1:

sudo su    
visudo -f /etc/sudoers

add add following line at the end.

jenkins ALL= NOPASSWD: ALL

回答2:

username ALL= NOPASSWD: ALL in sudoers worked in ubuntu server 12.04.2
