Hardware:

1.PC Machine one set.

Background knowledge:

1. VMware:

VMware Workstation is one of the commercial software products that vmware companies sell. The workstation software includes a virtual machine suite for the intel® x86 compatible PC that allows users to create and run multiple x86 virtual machines at the same time. Each virtual machine instance can run its own guest operating system (but not limited to) such as Windows, Linux, BSD-versioned versions. In simple terms, a VMware workstation allows a real computer to open and run several operating systems simultaneously in one operating system. Other VMware products help manage or migrate VMware virtual machines across multiple host computers.

3. Linux operating system:

Simply put, Linux is a free-to-use and freely-propagated Unix-like operating system that is designed and implemented by thousands of programmers around the world. The aim is to create Unix-compatible products that are free to use worldwide, without the copyright restrictions of any commodity-based software.

The advent of Linux began with the first Finnish university student named Linus Torvalds. His aim is to design an operating system that replaces the Minix (an operating system teaching program), which can be used on a 386-, 486-, or Pentium-processor PC, and has the full functionality of the Unix operating system, thus beginning the design of the Linux prototype.

Linux is used primarily as part of a Linux distribution. A typical Linux distribution includes: Linux kernel, some GNU libraries and tools, command line shell, graphical interface X Window system and corresponding desktop environment, such as KDE or GNOME, and contains thousands of kinds of applications from office suite, compiler, text editor to scientific tool 。 This section describes how to customize the installation of a well-known release version of the Linux operating system according to our course needs--rhel6

Installation of 1.VMware:

Figure 3-32 VMware Installation Method

2. Select Start VMware on the desktop, create an empty folder on the computer, it is recommended to select a larger disk to create the directory, if we create a folder in the D:/VM

3. Via "File" "New" "Virtual Machine" or by clicking on the icon (new virtual machine),

Open the New Virtual Machine Wizard, shown in 3-33, and select indicate user customization.

8. Select the size of the memory allocated to the virtual machine,the memory of thepc is larger, you can choose 1024MB, according to your

PC physical memory size to handle. However, if you want to run the graphical interface, it is recommended above 256MB . As

shown in the figure.

Allocate virtual machine maximum disk size

11. Click "Next" to go to the next step, select the location where the virtual machine disk file rhel6.vmdk is stored, and the recommended setting is the virtual machine installation directory set up previously. As shown in 3-41.

Figure 3-41 Set Disk File storage location

Click "next" to proceed to the next step and click Finish to install the RHEL6 virtual machine settings. as shown in 3-42.

13. After the custom virtual machine is complete, the virtual machine is displayed in the "My computer" on the left side of the virtual machine software "Red Hat

Enterprise Linux 6 ".

14. Load the RHEL6 installation image file with the virtual machine's optical drive. From the menu "VM" | "Settings", open the interface as shown. Select in the Device list box, or in Figure 3-44

Double-click to select the CD/DVD (IDE) option and select it in the Connect item and browse to and select the RHEL6 image file you want to install. RHEL6 mirroring in training-specific

and through the software/Red Hat Linux installation CD image folder, click "OK" to confirm the exit.

Figure 3-44 Add RHEL6 Mirror to the virtual machine's optical drive

After selecting the image of the virtual optical drive, go back to the figure 3-45 interface, select, launch the virtual machine into the RHEL6 installation interface, move the mouse into the virtual machine and select Enter. When you hover your mouse over a virtual machine, you cannot move out of the mouse, using

The "Ctrl+alt" combo key is moved out.

Enter the RHEL6 installation interface

16. Select whether to detect the integrity of the disc, as we are using the iOS image intact,

So by "←" "→" Select "Skip" Skip, 3-46, and then formally entered the RHEL6 Installation Wizard interface, 3-47 shown. Click "Next" to go to the next step, select the operating system language, here selected Simplified Chinese, recommended to use the default language, 3-48 is shown. Click "Next" to go to the next step, select the keyboard language, using the default "American English style", 3-49 is shown. Click "Next" to proceed to the next step, select install using the device "Basic storage Device", shown in 3-50.

Summarize:

Through this experiment, we should master the method of custom installation of Linux system, including how to choose appropriate configuration according to the resources of the system, and install according to the requirements of development and use. Because you are installing RHEL6 on a virtual machine, you must also master the configuration and use of the virtual machine environment.
