D.2.2.12Set Root Password
Setting up a root account and password is one of the most important steps during
your installation.
Your root account is similar to the administrator account used on Windows NT
machines. The root account is used to install packages, upgrade RPMs, and perform
most system maintenance. Logging in as root gives you complete control over your
system.
Use the root account only for system administration. Create a non-root account for
your general use and “su “- to root when you need to fix something quickly. These
basic rules minimize the chances of a typo or an incorrect command doing damage
to your system
.
The installation program prompts you to set a root password for your system. You
cannot proceed to the next stage of the installation process without entering a root
password
Figure D-13. Set Root Password
Note: To become root, type “su -” at the shell prompt in a terminal window and
then press [Enter]. Then, enter the root password and press [Enter].
