RedHat Linux operating system configuration skills

As Linux continues to heat up in China, more and more people want to learn it. However, the vast majority of people have become accustomed to the silly Windows operating system. It is indeed very difficult for them to adapt to the Linux operating system at once. In particular, countless Linux commands are intolerable for those who have never been connected to DOS, which has brought great limitations to Linux's promotion in China. Therefore, in most cases, Linux appears in front of us as a high-end operating system.

Fortunately, in recent years, China's * strong support, and the world's hardware and software vendors in China to vigorously promote Linux, Linux has achieved great success. In addition, most versions of Linux support Chinese characters. What's even better is that X Windows has also been very beautiful and practical, which not only lowers the learning threshold for those who have just switched from Windows to Linux, it also helps them improve their enthusiasm for learning Linux.

In X Windows, we can complete most operations, with just a few commands. This is of great help for Linux learning. This article takes the most widely used RedHat Linux as an example to explain the basic configurations of the Linux operating system.

1. Add a user

The newly installed Linux generally has only one user, namely the root user, or the system administrator. He has unlimited power to the system and can modify or delete any file. Therefore, a slight carelessness may damage the system. For example, if the root user enters a simple command "rm-fr/", all files in the system can be deleted. Among them, "rm" is the file deletion command, and the "-f" parameter is mandatory, "-r" is used to delete files in the specified directory. "/" is the root directory. The entire command is to force delete all files in the system, which is highly destructive. Other misoperations may cause serious damage to the system. Therefore, to ensure security, we recommend that you do not Log On As "root" for normal operations. This requires you to create a new user.

You can create a new user by using commands in shell or in a graphic window like Windows. You can create a user with only one simple command in shell. For example, if the new user is text, right-click the desktop, select "New Terminal" to enter the shell, and enter "adduser text" to press the Enter key, enter "passwd text" and press Enter. Press the prompt to enter the password to create the new user "text ". (1 ):

　　

To create a new user in the graphic window, double-click the "start from here" icon on the desktop, click "system settings" in the window that opens, and then click "users and groups ", in the pop-up "RedHat User Manager", click "Add User" to create a user. After the user is created, you can log on with the new "text" account. If you need to use the root permission in shell later, you only need to enter the "su" command and press enter, and then enter the root password to temporarily perform operations as root.

2. Configure the Desktop

Log on to the new RedHat Linux operating system as text and enter the default Linux Desktop. The dark blue desktop gives you a warm feeling. (2 ):

In general, it is very similar to Windows desktop, and users familiar with Windows should be very easy to get started. In the upper-right corner, the default shortcuts are "main directory of text", "starting from here", and "recycle bin ". The "main directory of text" is the user's directory. The user enters his directory from here. "From here" is the place where the user configures the system, it is equivalent to Windows's "Control Panel", and the "recycle bin" is the same as Windows's "recycle bin" to store files temporarily deleted by users. If you are not satisfied with the desktop, you can change it by yourself. To change the desktop, right-click the blank area of the desktop and select "Change desktop background (B)". The "background preference" window is displayed. (3 ):

Here, you can change the desktop background color and wallpaper. To set an image as a wallpaper, you only need to click the default image under "select image (P)" in "background Preferences". The "select image" window is displayed, you only need to select the image you want to set as wallpaper, and then click "OK" to set the selected image as wallpaper.

3. Change the Panel

The bottom of the desktop is the Linux panel. To be honest, the default panel in Linux is really ugly, but we can customize the panel we like. Right-click the blank area of the Linux taskbar and click "properties". The "panel properties" setting window is displayed. (4 ):

Here, you can set it as you like. You can either place it on the top or bottom of the desktop or change its size, you can also set whether to automatically hide and change the background color or set the background image. On the left side of the Linux operating system panel is the default seven shortcut icons of the system, the options are "Main Menu", "Mozilla World Wide Web Browser", "Evolution email", "OpenOffice.org Writer", "OpenOffice.org Impress", "OpenOffice.org Calc", and "print manager ".
