Type su and hit enter, it will ask the root password. Type Ctrl-d to exit su.

To run a command without actually loggin in as root run...

Code:
su -c thecommandUwant2run
It'll prompt you for roots password, and if entered right, it'll execute the command for you.

sudo

You can also give your personal account the right to execute 'root-commands'. As root run:

visudo

You'll get to see a file which contains the line:

root ALL=(ALL) ALL

simply add this line beneath that one:

myuser ALL=(ALL) ALL

and save it. Now in the terminal you can use sudo to execute 'root-commands':

sudo theCommandYouWant

You'll be promted for your userpassword (NOT your rootpassword) when you use this the first time after opening the terminal.
And if you don't use sudo for a while in an already opened terminal.

I hope I made myself clear.

Good luck!

sudo is a good option for giving regular users access to run commands that can only be run by the superuser or another user. There are some neat security measures available within this utility. You'll want to look over the sudo and sudoers man pages to get a better idea of how it works.

Often when setting up new software or new procedures a regular user will run into roadblocks that can only be resolved by the superuser. The best way around this is to become superuser for a short time and then go back to your normal user account. This is done with the su command. I would recommend using su - over just su so that your default path gets set up properly. Otherwise programs in /sbin and /usr/sbin will not be recognized without using the full path or ./ in the directory where they are stored.
