I always set up /etc/sudoers to allow user many but not all root privileges
Using root is dangerous.

su
enter root password
vim /etc/sudoers
go to the line which says
## Allow root to run any commands anywhere
root ALL=(ALL) ALL
under that enter your username <tab> All=(ALL) <tab> ALL
where <tab> is the tab key.
esc wq! to save and quit

When you need root access from a terminal type sudo <some command> and 
it will ask for your user password.
type exit or close the terminal to exit sudo.

There are probably better ways but this works for me.
