How to run a script as root in Jenkins?

Solution 1:

You must run the script using sudo:

sudo /path/to/script

But before you must allow jenkins to run the script in /etc/sudoers.

jenkins    ALL = NOPASSWD: /path/to/script

Solution 2:

@Igor Chubin's answer is 100% correct, but never open sudoer file with a normal editor. always use visudo

just type

sudo visudo

this will take you to /etc/sudoers and upon saving it will make sure that there is no error in formatting.

if you make an error in sudoer file, you will lose sudo access, so always use visudo

Solution 3:

I do realise I'm late to the party on this question, but for reference sake I thought I'd throw my 2c in here: I use the SSH plugin for Jenkins to accomplish this (simply configure a localhost target). In this way, I can contain the script directly within Jenkins (like a normal "Execute shell" step), instead of using sudo to invoke an external script.
