Selecting a 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.
The installation program will prompt you to set a root password for your system. You must enter a root password. The installation program will not let you proceed to the next section without entering a root password.
The root password must be at least six characters long; the password you type is not echoed to the screen. You must enter the password twice; if the two passwords do not match, the installation program will ask you to enter them again.
You should make the root password something you can remember, but not something that is easy for someone else to guess. Your name, your phone number, qwerty, password, root, 123456, and anteater are all examples of bad passwords. Good passwords mix numerals with upper and lower case letters and do not contain dictionary words: Aard387vark or 420BMttNT, for example. Remember that the password is case-sensitive. If you write down your password, keep it in a secure place. However, it is recommended that you do not write down this or any password you create.
To change your root password after you have completed the installation, use the Root Password Tool. Type the redhat-config-rootpassword command in a shell prompt to launch the Root Password Tool. If you are not root, it will prompt you for the root password to continue.
A root password is the administrative password for your Red Hat Linux system. You should only log in as root when needed for system maintenance. The root account does not operate within the restrictions placed on normal user accounts, so changes made as root can have implications for your entire system.
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].
