Running a script without password
Why do we need?¶
As part of automation of services, we need to issue certain commands as sudoer.
One typical use case I came across is to restart the ngnix once the Hugo content is rebuild. In this case, if sudo requires password, we can't trigger it in script.
🛑🛑🛑 Making scripts to run with sudo password is a security risk, and assumption here is that the machine access is restricted and secure. 🛑🛑🛑
How it can be done?¶
Open sudoers file for your user
update the commands that we want to call without sudo password as below.
myusername ALL=(ALL) NOPASSWD: /usr/sbin/service nginx start,/usr/sbin/service nginx stop,/usr/sbin/service nginx restart
we can add any script that is executable as root.
