RedHatLinux9.0 hard disk installation guide

Three files RedHatLinux9.0 shrike-i386-disc1.iso; shrike-i386-disc2.iso; shrike-i386-disc3.iso. Decompress the data to any partition X: \ CD1, X: \ CD2, X: \ CD3. if you want to install dual systems, install a DOS (98 is not required ), and make sure that the disk partition you store is not in the NTFS format, restart the machine to enter DO

Three RedHat Linux 9.0 files
① Shrike-i386-disc1.iso;
② Shrike-i386-disc2.iso;
Shrike-i386-disc3.iso.

Decompress the data to any partition X: \ CD1, X: \ CD2, X: \ CD3.

If you want to install a dual system, install a DOS (98 is not required), and make sure that the disk partition you store is not in the NTFS format, then restart the machine and enter the DOS prompt, go to the DOSUTILS directory in the directory where CD1 is stored, and execute the autoboot directory. bat files, such:

X: \ CD1 \ dosutils \> autoboot. bat press ENTER

The rest is simple, and you will feel like installing Windows.
1. Select the system default language
RedHat supports languages in almost all countries in the world. Here, you only need to hook up in front of Simplified Chinese and select the system's default language as simplified Chinese. After the installation process ends and the system starts, the interface of the entire operating system will be in simplified Chinese. You do not need to perform any additional cultural operations or settings.

2. Partition operations

Next, we will work on disk partitioning. This may be the only step that requires more user intervention throughout the installation process, REDHAT Linux 9.0 provides two partitioning Methods: automatic partitioning and manual Partitioning Using the disk druid Program

1) automatic partitioning: if a new computer does not have any operating system, we recommend that you use the "automatic partitioning" function, which automatically depends on the disk and memory size, allocate disk space and SWAP space.

This is a "dangerous" function, because it will automatically delete the data on the original hard disk and format it into a Linux partition File System (EXT3, REISERFS, etc ), therefore, you can use the "automatic partitioning" function unless there is no other operating system on your computer or no data to be retained.

(2) manual partitioning: if there are other operating systems on the hard DISK or data on other partitions needs to be retained, we recommend using the disk druid program for manual partitioning. Disk druid is a GUI partition program that can conveniently Delete, add, and modify attributes of DISK partitions, it is more user-friendly and intuitive than the character interface Fdisk program used in previous versions. Next let's take a look at how to partition the hard DISK using the disk druid program.

Because the Linux operating system needs to have its own file system partition, And the Linux partition is different from that of Microsoft Windows and cannot be shared, you need to open one (or several) for Linux separately) partition. Linux generally uses EXT3 partitions, which is also the default file system used by REDHAT Linux 9.0.

There are two ways to create a file partition for Linux: one is to create a Linux partition using idle disk space, and the other is to edit an existing partition to make it a Linux partition. If there is no free disk space, you need to delete the existing partitions and free up space to create Linux partitions.

The disk druid program has buttons such as create, delete, edit, and reset. You can operate disks intuitively. When using disk druid to operate DISK partitions, four important parameters need to be carefully set: mount point, file system type, drive, partition size

Mount point: it specifies the directory of the Linux file system corresponding to the partition. Linux allows you to map partitions on different physical disks to different directories, in this way, different service programs can be deployed on different physical disks. When one of the physical disks is damaged, data on other physical disks will not be affected.

File System Type: Specifies the file system type of the partition. The options include EXT2, EXT3, REISERFS, JFS, and SWAP. After creating a Linux Data Partition, it is necessary to create a SWAP partition. It is actually a Virtual Memory Simulated by a hard disk. When the system memory usage is high, the kernel automatically uses the SWAP partition to simulate the memory.

Size: The partition size (in MB). You can enter the size of the Linux Data Partition based on your actual situation, the SWAP size can be set to twice the physical memory size, but when the physical memory is larger than 1 GB, the SWAP partition can be set to 2 GB.

Allowed drive: if there are multiple physical disks on the computer, you can select the physical disk to be partitioned in this menu option.

After partitioning the disk, the installation process is relatively complex, and the next installation will be smooth. Let's continue to select the system components to be installed.

3. Select the installation component

REDHAT Linux 9.0 is similar to the previous version in the selection of installation components. You can choose either the desktop computer, workstation, server, or the simplest installation method, you can also define the software packages to be installed, and the installer can estimate the required disk space in real time, which is very convenient for users.

After the system components are installed, the installer automatically copies the selected software package from the disc medium to the hard disk of the computer without manual intervention, each system component is briefly described when it is installed.

When selecting a software package, if you want to further configure the system, you can select a custom software package set. We recommend that you customize the KDE Desktop environment so that you have two desktops that can rival Windows XP

How is the installation process simple? Of course, this is not the last step, because after all system components are installed, the installer will remind you to create a boot disk for emergency purposes.

So far, the Linux system has been successfully installed.

3. Change the Startup Mode

It is more fun than Windows.

By default, REDHAT Linux 9.0 automatically starts X-Window at startup to enter the graphic operation interface. Many Linux hardcore players are used to working on the Console character interface, or some players may think that X-Window is too slow to start and like intuitive and fast Console operations.

1. Enter the character page

To directly enter the Console interface when Linux is started, you can edit the/etc/inittab file. Find id: 5 :? Initdefault: change this line to id: 3: initdefault: And then restart the system. We can simply change 5 to 3 to convert the X-Window Graphic operation interface or Console character interface at startup, this is because the Linux operating system has six different run levels. At different run levels, the system has different states. These six run levels are:

0: Shutdown (remember not to set initdefault to 0, because this will make Linux unable to start)
1: single-user mode, just like the security mode in Win9X.
2: multiple users, but not NFS.
3: full multi-user mode, standard operation level.
4: It is generally not used. In some special cases, you can use it to do something.
5: X11, which means entering the X-Window system.
6: restart (remember not to set initdefault to 6, because this will make Linux continuously restart ).

Among them, running level 3 is the standard Console character interface mode we want to enter.

2. Free conversion character interface and X-Window graphical interface

After learning about the conversion between the X-Window Graphic operation interface and the Console character operation interface, you may think that each of these two operation interfaces has its own advantages, can I be greedy and have these two interfaces at the same time? In a omnipotent Linux operating system, this requirement can certainly be met.

In the X-Window Graphic operation interface, press "Alt + Ctrl + function key Fn? N = 1 ~ 6 ?" You can enter the Console character operation interface. This means that you can have X-Window and six Console character operation interfaces at the same time. This is an exciting thing!

On the Console character operation interface, how does one return to X-Window? Simply press "Alt + Ctrl + F7. In this case, seven screens are displayed in Linux by default, numbered tty1 ~ Tty7. After X-Window is started, tty7 screen, tty1 ~ Tty6 is still a character screen. That is to say, you can use the "Alt + Ctrl + Fn" combination key to quickly switch between the character interface and the X Window Interface.

Linux users all know that X-Window is a very convenient graphical interface. It can be operated with the mouse, but it also has many disadvantages: such as slow startup and running speed, insufficient stability, poor compatibility, and easy to crash. However, once an error occurs in the X-Window system, it does not cause the entire Linux system to crash and cause data loss or system damage, because when X-Window loses response or crashes due to itself or applications, we can easily exit X-Window and go to the Console for troubleshooting, all you need to do is press the "Alt + Ctrl + Backspace" key, which means that as long as the system does not lose the response to the keyboard, any problem occurs in X-Window, and you can exit easily.
