OK so I am working with Ubuntu servers (no, I haven’t abandoned CentOS, just broadening the horizons).
Anyway, Ubuntu is different in that, rather than creating a root password during the install, it has you create a user account with sudo permissions.
However, whenever you type sudo ‘this’ or sudo ‘that’, Ubuntu asks for your password. Every time. Gets kind of annoying after a while.
So… search for Sudo without password on Ubuntu and problem solved!
sudo visudo
Add this line at the end (change “jerome” to your username):
jerome ALL=(ALL) NOPASSWD: ALL
Ctrl-X to leave, save your changes, and you’re done!
