1, add Users

The newly installed Linux typically has only one user, the root user, the system administrator. He has unlimited power over the system to change or delete arbitrary files, so a slight carelessness can damage the system. For example, root simply type a simple command "RM–FR/" to delete all files within the system. Where "rm" deletes the file command, the "-F" parameter is mandatory, "-r" is used to delete the file in the specified directory, "/" means the root directory, and the entire command deletes all files in the system. It can be seen as devastating. There are other misoperation can also cause serious damage to the system, so for the sake of security, normal operation we should not log in as "root", which requires a new user. New users can be created with commands under the shell or in the graphics window like Windows. You can create a user with a simple command under the shell. For example, the new user is text, we just follow the steps below: Right click on the desktop, select "New Terminal" that goes into the shell, and then enter "AddUser text" press ENTER, and then enter "passwd text" return, as prompted to type the password that creates a new user " Text ". As shown in figure (1):

If you want to create a new user in a graphical window, double-click the "Start Here" icon on your desktop, click "System Settings" in the open window, click "Users and Groups", and click "Add User" in the pop-up "RedHat User Manager" to create a new user. After you have built the user, you can log in with the new "text" account. In the future, if you need to use the root in the shell, as long as the input "su" command and then enter the password, and then input root, you can temporarily operate as root.

2, configure the desktop

Log in as text login just new Redhat Linux, entered the default Linux desktop, dark blue desktop gives a very warm feeling, such as figure (2):

Generally speaking, it is close to Windows desktop, and users familiar with Windows should be easy to get started with. The upper-right corner is the default shortcut, which is "home directory for Text", "Start from Here", and "Recycle Bin." "Text's home directory" is the directory of the logged-in user, the user enters his or her own directory from here; "From here" is where the user makes the system configuration, the equivalent of Windows Control Panel, and the Recycle Bin, like the Windows Recycle Bin, where users temporarily delete files. As for the desktop, if not satisfied, you can change it yourself. To change the desktop, simply right-click in the desktop space and choose Change Desktop Background (B) to pop up the background preferences window. As shown in figure (3):
