how to set up root account on a new install?

view story

http://askubuntu.com – I just installed ubuntu on my netbook and am loving it!! What I’m now trying to do is set up my root account. I tried to run the following command at a command prompt: su root and use the password for the main account i set up during the install process. but that didn't work. so then i tried "sudo password root" in an attempt to change the root password, but i get the following error message: cp@cp-AOA150:~$ sudo password root sudo: password: command not found any suggestions on how i can fix this? i need to start installing tools like apache2 but i can't without being root (HowTos)
