Section I: Computer architecture and Linux background knowledge

1) The composition of the computer is divided into five parts: control unit, Operation unit, memory unit, input \ Output unit.

1. Controller: is the central nervous system of the whole computer, its function is to explain the control information prescribed by the program, control according to its requirements, dispatching program, data, address, coordinate the work of each part of the computer and access to memory and peripherals.

2. Datapath: The function of the operator is to perform various arithmetic and logical operations on the data, i.e. processing the data.

3. Memory : Memory function is to store programs, data and various signals, commands and other information, and when necessary to provide this information.

4. Input system: Input device is an important part of the computer, the input device and output device is called external device, referred to as peripheral, the function of the input device is to the program, raw data, text, characters, control commands or data collected in the field of information input to the computer. Common input devices are keyboard, mouse, photoelectric input machine, tape drive, disk drive, CD-ROM machine and so on.

5. Output system: The output device and the input device is also an important part of the computer, it put out the intermediate results or the final result of the machine, various data symbols and text or a variety of control signals and other information output. The output devices commonly used by microcomputer are display terminal CRT, printer, laser printing machine, plotter and tape, CD-ROM machine and so on.

2)Operating System(Operating SystemOS) is the management and controlComputerHardwarewith theSoftwareof ResourcesComputerprogram, is run directly on the "Bare Metal"On the most basicsystem software, any other software must beOperating Systemsupport to run. Operating system boards to include:Process management (processing management), memory management, filesystem (file system), network communication (Networking), security, user interface interface), drivers (devicedrivers).

3) server operating system Instance

server operating systems generally refer to the installation of the Mainframe Computers on the operating system, such as the Web Server , Application server, and Database Server and so on. Server operating systems are concentrated in three main categories:

2. Unix Series: SUN Solaris , Ibm-aix,hp-ux, FreeBSD , OS X Server

4. Linux series : Red Hat linux,centos,debian,ubuntuserver, etc.;

6. Windows Series: Windows NT Server, Windows Server 2003 , Windows Server , Windows server r2,windows Server 2012,windows Server technical, and so on.

8. 4) Four components of Linux: Kernel, Shell, file system, application

14. Section II: Planning and installation of Linux hosts and use of VMware, Xmanager.

16. 1) Linux Installation documentation

18. 2) Vmware Workstation install Linux

20. 3) Xmanager Use the document

22. Annex

28. Section III: Start the Linux system with help and switch and basic operational knowledge.

30. 1) Small operation:

32. Restart X-window:alt+ctrl+backspace

34. Ctrl+alt+f1-f6:tty1-tty6 terminal to allow users to log in. Back to KDE:ctrl+alt+f7

36. Default root Prompt #, general identity prompt is $

38. Commands: command [-option] Parameter1 parameter2

40. \ used to escape, case sensitive

42. Basic command:

44. Ls-al/root

46. Date +%y/%m/%d

48. TAB: Command completion or file completion

50. tab after the first word after a series of commands, for command completion

52. tab to complete the file after the second word after a series of commands

54. CTRL + C: interrupts the current command

56. Ctrl+d: Enter End exit

    
    

58. Shutdown command:

60. 1.shutdown:

62. #shutdown-H now//Shut down immediately, it is equivalent to time of 0

64. #shutdown-H 20:25//system shuts down at 20:25 today

66. #shutdown-H +10//system automatically shuts down after 10 minutes

68. #shutdown-H-r now//system restart immediately =reboot

70. #shutdown-R +30 ' The system will reboot '////30 minutes after the reboot, and the actual information
