Red Hat Linux 7.0 Installation Use Notes (1)
Recent major news about Linux products is the listing of the Red Hat Linux 7.0 version. As a top manufacturer in the industry, his movement is eye-catching. In the world of Linux, the software product version is 6.2 "bounce" 7.0, you can think that the product has a large improvement. So, how is the face of this "small red hat"? Let us take a look. According to the official aspect of RedHat, Redhat 7.0 uses XFree 4.0, which provides better graphics card support, and more convenient configuration, support USB devices and more hardware. Of course, the appetite is also bigger, the workstation type is installed at least 900MB free hard disk space, recommended 64MB of memory, preferably 128MB. However, due to the installation process, the configuration is highly flexible, 300MB can be installed, but the software that can be used is too small. Because I got a strong helpful help, I went smoothly with the Red Hat Linux 7.0 disc. Two, the first one can start directly from the CD, including most packages and some installation tools. In addition to additional software packages, the second optical disk is mainly the source code, preview software, etc. - such as Glibc, KDE, 2.4 test version kernel code. Red Hat made improvements that allow the installer from multiple discs, because the software developed under Linux is too fast, a disk capacity is thinner, and it will not be able to hold it. Below is a brief description and experience of the installation process. Sed into the first disk, let the computer start from CDROM, and there is a simple welcome information immediately. Tap the car, you can enter the default installation mode - a graphical interface, mouse operation, basics, and 6.1, 6.2. Type "Text", you can enter text installation mode, and similar to the previous version of 6.0. No mouse is not supported, you need to use a keyboard operation, mainly for compatibility. If your computer uses graphics mode, it is not easy to use. For example, the screen is surprising, but how can the button can't find it, then this mode is used. Enter "Expert", you can enter the so-called expert model. In fact, the installer will give you all the steps. How do you set it with it, if your machine is a special hardware, the installer cannot be properly configured, then Just try this way. Typing "Linux Rescue" will enter the "rescue" mode, mainly for the original Linux system that cannot start normally. Use this method, in fact, you have entered a miniature Linux system, there are many tool programs that can be used to save the operating system. If you have a special hardware installation drive, type "Linux DD", which will prompt you to insert the floppy disk and read the system. To make better use them.

Knocking back to the default installation mode, after the kernel is started, there is a language selection menu, 18 languages, but unfortunately there is no Chinese. Choose "English", then pick the keyboard, mouse. It is worth mentioning that my double frying 4D mouse automatically recognizes three bonds. You know, the third button has a lot under the Linux environment. Many operations can be implemented with it. If you don't have a three-button mouse, use the simulated three-button method, right click, simultaneously, ie, the third button is represented.
The installation interface is very easy to use, there is a timely and detailed help message on the left, and the right is an option. Fully mouse operation.
In the system installation, the most important thing is to see the left instructions! Because many friends have a painful lesson - not careful, as a result, all things in the hard disk are killed, the system is paralyzed. I want to cry without tears, and some people keep going to the Internet to recover. Here, in detail, Redhat 7.0 has two major class installations: install or upgrade. The former contains three options: Workstation, Serversystem, Custem System. It can be easily switched with a mouse. The latter is an upgrade program, using RPM, can replace the old version of Linux software for the hard disk.
WorkStation --- General User Recommend this method. Workstation Type Installation will clear all the original Linux partition information on all hard drives. Regardless of the partition-independent of Linux, if you smell the dead 98. However, the installation is very easy, if the hard disk has Windows98, it will automatically configure the two boots of LILO, but if you compute with NT, don't use this method, you should use custom methods, otherwise, it is likely that your NT will never start. coming.
Serversystem --- Server Type Installation will do everything about all partitions on all hard drives. Never kidding! If your machine is used as a web server, use it.
CUSTEM SYSTEM - The installation of customized types. Don't like the type above, or try the free configuration process, use it.
I use the workstation type, the following steps are partitions, if you are insufficient, or you can use the automatic partitioning method, the installer automatically creates "/", "SWAP", "/ boot" partition. Of course, the Linux partition information on the hard disk is all erased, while Windows98 does not take it, it will be safe.
In fact, I am more accustomed to manual partitioning, more flexible, can be configured on demand. For example, in order to be safe, it is necessary to separateize the root partition, and install a large number of packages separately in other partitions, etc.
After formatting the partition, the following is a very interesting time zone selection, there is a world map on the right side, the mouse arrow is put, the program automatically selects the nearest area time zone, and we must choose China.

Next, enter the password of the superuser -root, or you can establish the necessary ordinary user account here. Note that the password is a very important barrier, it is best to use the case form of the uppercase letter mixing numbers. MD5 Password and Shadow Password are also indispensable.
When choosing a package group, there are three kinds of gnome, kde, games, it seems that redhat is very thoughtful for games. Note that the group can be multi-selection, any combination of three packets can be installed.
My suggestion: If it is a software mad, (Just Like Me!) I want to have an eye addiction, then select the "SELECT Individual Packages" button under the screen. Install the required packages separately.
The installer automatically generates a very friendly package selection interface. The left is a tree image. All packages are divided into different belongings, such as Internet applications, X windows, software development, databases, shared library files. and many more. The right side is the icon representing the software, the state of "tick" means the selection, and the lower side of the screen is the annotation instructions for the right package, what is the characteristic of this software.
I found a lot of newly released programs, see, operate digital cameras, support ISDN, using a burner, scanner. Will the mouth? I believe soon, Linux can't support the history of new hardware, it is going to become. This part should also be one of the new features belonging to Redhat 7.0. The procedure of the procedure is usually, configure the X window, select the display, and pick the video card. My premedia2 can be easily recognized, and this, the latest turbolinux6.1 has not been done. This may be due to X Free 4.0. TurboLinux 6.1 is used in X Free 3.3.6.
Customize the appropriate X resolution, select the default window environment, then test it, continue, otherwise it will be re-adjusted until success. I selected "800x600", 24 colorful color for my 14-inch display (old soil :-).
The real copy process begins, look at the estimated time, you can go to drink tea, but come back, because finally need to use the second CD to complete the installation, then make the boot floppy disk, do not jump. Map, "Congratulations to the installation."
Red Hat Linux 7.0 Installation Use Notes (4)
After an urgent reboot, it was found to have a new change. RedHat 7.0 describes the LILO boot interface. The screen displays a small red hat image and the operating system that needs to be started. Use the keyboard arrow to switch. Unfortunately, I don't like this graph. For me, it is too rough.
Go to the Linux system. It can be seen that the system uses the 2.2.16-22 version of the core, the big name Ding Ding 2.4 is coming in! Fortunately, there is a beta version, you can taste fresh.
First look at whether the hardware is fully utilized, and the result uses the "free" command to see, my 128MB memory is only 64MB. Hey, use vi to open /etc/lilo.conf,
Boot = / dev / hda
MAP = / boot / map
INSTALL = / boot / boot.b
Prompt
TIMEOUT = 50
Message = / boot / message
Default = Win98
Image = / boot / vmlinuz-2.2.16-22
Label = Linux
Read-only
root = / dev / hda8
Other = / dev / hda1
Label = Win98
Join append = "MEM = 127m", by the way, the unfiusible graphic is passed. The result is this:
Boot = / dev / hda
MAP = / boot / map
INSTALL = / boot / boot.b
Prompt
TIMEOUT = 50
# message = / boot / message
Append = "MEM = 127m"
Default = Win98
Image = / boot / vmlinuz-2.2.16-22
Label = Linux
Read-only
root = / dev / hda8
Other = / dev / hda1
Label = Win98
Run lilo -v, now it is fine.
Red Hat Linux 7.0 Installation Use Notes (5)
The sound card under Linux is "Bruce Difficulties", although there is OSS, it is commercial software, although ALSA is free software, but the configuration is a bit complicated. If you provide sound card support by the system yourself is the most ideal.
Type: SNDCONFIG, the result is great to be surprised! My Yamaha 724 sound card did not expect any strength to recognize it, less than 10 seconds before and after configuration. When testing the sound card, the sound used is the "hello, this is ..." that everyone is very familiar with the "Hello, this is ...", and the number of Sound cards supported by Redhat 7.0, and the number of hardware supported is the previous version. Many times! The famous Sound Blaster AWE / Live is also named.
Enter: startx, open the X window, soon entered the default GNOME window environment, um, the new version of the software does have new tastes. The 16 desktop topics Everything is unleading. Highly personalized, almost customize the system environment according to their own preferences. The software start menu is set to WIN98 is very similar. A wide range of software tools are very complete. Look at the picture with an electronic eye, how to make a picture with Photoshop, and Email, ICQ, FTP, dial-up network, text processing, game, etc.
If you choose KDE and games at installation, you will find them in the menu. KDE has a single optional single item that contains its application.
The display shows that the graphics is also very clear, because there is a good version of Linux that is a 14-inch display for me. X window model is vague, as well as electric wave stripes, I have been worried whether it will explode.
In fact, general displays are selected as long as they select a reasonable refresh and its resolution parameters, and there is basically no problem with the X-window environment. Remember: Once the window environment is adjusted, first back up the / etc / x11 / xf86config file! After the "martial" is changed later, it will be copied directly, because this file is common, so you can hassine. The most annoying is that there is often someone on the Internet: I can use the Linux and X window with Linux and X windows? It's a hateful tooth root. Is it a poor egg?
Personally, this Linux system is running very fast, and there is no hysteresis that opens large packages. (Machine environment is Celeron 366 MSI 6199VA motherboard gold diamond second generation 10.6GB hard drive 128MBKINGMAX memory)
It's better to operate more than TurboLinux6.1, which may be due to its exacerbation of Chinese character systems to occupy resources. It should be noted that RedHat 7.0 supports Chinese support is zero. There is no control. All Chinese characters are displayed in a bunch of chaos, and no one knows characters. I want to get Chinese support, I have to install the plug-in Chinese character system or wait for the Chinese version of the small red hat. Either, use TurboLinux or other Chinese version of Linux.
"Close window" Red Hat Linux 7.0 Installation Use Notes (6)
When the disc is placed, the program automatically loads, open the disc, eliminating the trouble of manual operation. (Walking to Windows98?) No matter how it is said to make the user's easy use.
Speaking here, I have to give a small red hat. This is also a point in the red ht focus: system bug.
At present, the user is batching a small red hat, and even requested returns. The industry is also blaming. Some people say that there are 2,500 bugs in 7.0. This statement may exaggerate, but the problem is indeed more.
Single talker X window, sometimes the system black screen during operation, no response. Of course, where will Linux crash? : ->, press CTRL ALT retaining keys to force exit.
Also, sometimes the system enters the screen protection state, it will never go back. The disc is opened, but the optical drive button is not locked, and the exit button on the light-drive panel can also pop up the disc, even replace the disc! This is hard to imagine in the Linux system. Because the system operation running mechanism and Windows are not very different, the disc or other storage medium (such as a floppy disk) is used first, and when the media needs to be uninstalled. Otherwise, it will mess with the system buffer and the actual content. Therefore, all Linux systems that are basically all, lock the buttons when using the optical drive, so that it doesn't work. Recovered until uninstallation. However, Redhat7.0 has a joke, I have changed the CD, it doesn't pay attention, and I can't read it again. Even if the manual operation is not helpful. I have to restart the Linux system to solve the problem. When exiting the Linux system environment, use the "Halt" command to automatically shut down the ATX power system. I have to manually operate. And other Linux distributions are uncertain in turbolinux6.1.
However, I believe that the system is because there are too many new things to lead so many questions. Support for new hardware, known as GCC compiler with huge progress, the latest application packages, etc. are all made together, it is a bit difficult for him.
RedHat7.0 has improved on network services and database support. Inherited the feature of the previous version of the configuration, there is a support of the practical configuration programs such as "LinuxConf" and "NetConf", and can be used smoothly in the terminal environment and the X window environment. The system is bundled with popular mysql3.23.22-6., PostgreSQL7.0.2-17 database software, and widely used PHP software packages - PHP4.01, the author does not actually apply them due to the limited conditions. It will not be described again here. Interested and actual friends can view software lists, install applications themselves.
Overall, RedHat7.0 has great progress on new hardware support, but there are also some problems that are not mature, there are many bugs. Do you use it or let your friends decide.
