7.17. Set the 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 Microsoft Windows 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.
Note
The root user (also known as the superuser) has complete access to the entire system; for this reason, logging in as the root user is best done
only
to perform system maintenance or administration.
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.
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
.
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.
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 asks 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.
Note
Do not use one of the example passwords offered in this manual. Using one of these passwords could be considered a security risk.
Note
To change your root password after you have completed the installation, use the
Root Password Tool
.
Type the system-config-rootpassword
command in a shell prompt to launch the
Root Password Tool
. If you are not root, it prompts you for the root password to continue.
Enter the root
password into the
Root Password
field. Fedora displays the characters as asterisks for security. Type the same password into the
Confirm
field to ensure it is set correctly. After you set the root password, select
Next
to proceed.
