1 is a flowchart illustrating a method of initializing an operating system of a public computer according to an embodiment of the present invention, and FIG. 2 is a diagram illustrating a computing system according to an embodiment of the present invention. The method 100 of FIG. 1 can be applied to the system 200 of FIG. 2 or other systems. Similarly, the system 200 of FIG. 2 may operate in the method 100 of FIG. 1 or other methods. However, hereinafter, for convenience of description, the technical idea of the present invention will be described as an example in which the method 100 of FIG. 1 operates in the system 200 of FIG. 2.

1 and 2, in the method 100 of initializing an operating system of a public computer according to an embodiment of the present invention, a central computer (CCOM) and a plurality of public computers (PCOM) are signally connected through a network. In the computing system 200, first, any public computer PCOM among a plurality of public computers PCOM is network booted under control of the central computer CCOM (S110 ).

The central computer (CCOM) has an environment for controlling network booting in each of the plurality of public computers (PCOM). For example, the central computer (CCOM) according to an embodiment of the present invention may include a network boot control unit 221, a boot file transfer unit 222, an IP address allocation unit 223, and a network storage control unit 224. have. The network boot control unit 221 exchanges configuration information, including exchange of boot files, between the central computer CCOM and each public computer PCOM. For example, the operating system initialization method 100 and the computing system 200 of a public computer according to an embodiment of the present invention may perform network booting using a Pre-boot eXecution Environment (PXE) method, in this case , The network boot control unit 221 may include a PXE server. The boot file transfer unit 222 transmits a file required for PXE booting, for example, a boot image file or an OS image file, and may include a Trivial File Transfer Protocol server (TFTP server). Files required for PXE booting may be provided in a partition other than an image. The IP address assignment unit 223 allocates a corresponding public computer IP address to identify the public computer (PCOM) to which the boot file transmission unit 222 wants to transmit the boot file, for example, a DHCP server (Dynamic Host Configuration). Protocol server). The network storage control unit 224 provides storage space required for network booting of a public computer (PCOM), for example, IP-based storage networking that connects a data storage facility in a computing environment to the public computer (PCOM) through a network. It can operate based on the standard ISCSI. The central computer (CCOM) according to an embodiment of the present invention may adopt, for example, Linux as an operating system that collectively controls the above operation.

The plurality of public computers PCOM may include a control unit 242 and a storage unit 244, respectively. The control unit 242 may be a central processing unit installed on the main board, and the storage unit 244 may be a hard disk drive on which an operating system is installed. However, the present invention is not limited thereto, and the storage unit 244 may be implemented as a solid state drive (SSD). However, for convenience of description, hereinafter, only an example in which a hard disk drive is implemented as the storage unit 244 will be described.

Each of the plurality of public computers (PCOM) may determine a booting sequence through the setting of a basic input output system (BIOS). In an embodiment of the present invention, network booting is performed by local booting, that is, It is described only that it is selected before the hard disk drive booting method. As described above, the storage unit 244 according to an embodiment of the present invention may be implemented with a disk other than a hard disk drive, and in this case, a boot order so that a booting method using the disk is selected in a higher priority than network booting. Will be set.

Next, the operating system initialization method 100 of the public computer according to an embodiment of the present invention includes the steps of initializing the storage unit 244, that is, the hard disk drive by the public computer (PCOM), the network booted operating system ( S). HDD initialization of the public computer PCOM may be performed by a network booted operating system of the public computer PCOM under the control of the public computer initialization control unit 242 included in the central computer CCOM. The public computer initialization control unit 242 may perform initialization by overwriting the OS image file on the hard disk drive of the public computer (PCOM). In the OS image file, OS stands for Operating System. An OS image file is a file stored on a hard disk drive of a public computer (PCOM), that is, an operating system or program as one image file. The common computer initialization control unit 242 may generate an OS image file using a program that can copy an entire partition of a hard disk drive and store it as a single file, such as a Linux dd (data duplicator) program. The OS image file may be stored in a storage area accessible by a central computer (CCOM), and the storage area may be allocated and controlled by the aforementioned ISCSI protocol.

By overwriting the OS image file by the public computer initialization control unit 242 on the hard disk drive of the public computer to be initialized, the public computer's hard disk drive is initialized, and personal information and documents left by the user who used it before And no information about the program remains. The central computer (CCOM) may turn off the initialized public computer.

1 and 2, until the public computer initialized through the above operation is turned on again (turn-on) by the next user, the central computer CCOM is the corresponding public computer. Can be processed in standby mode. When the public computer is processed in the standby mode, the central computer CCOM may perform the above-described network booting (S110) or initializing (S120) operation for other public computers other than the public computer. One or more public computers of the multiple public computers (PCOMs) may be processed in standby mode, either alone or simultaneously. The standby mode is maintained until the corresponding public computer is turned on (NO in S140).

When any public computer (PCOM) being processed in standby mode is turned on (YES in S140), the public computer (PCOM) attempts to boot the network first according to the boot priority order set in the BIOS, as described above, however, The network boot control unit 221 of the computer CCOM bypasses the request (S150). When the central computer (CCOM) does not respond to the request even after a certain time has elapsed, the public computer (PCOM) boots using the hard disk drive booting method according to the boot priority order set in the BIOS (S160). A public computer (PCOM) is booted into the operating system and programs of an initialized hard disk drive and provides its use to the user.

3 is a diagram showing the interaction between a central computer and a common computer according to an embodiment of the present invention.

1 to 3, the step S110 in which the public computer PCOM is network-booted by the control of the central computer CCOM of FIG. 1 is completed when the first user completes the use of the public computer PCOM. After the computer PCOM is turned off, the central computer CCOM can be started after the public computer PCOM is turned on again. As described above, the public computer (PCOM) requests a network boot having a priority by the BIOS setting to the central computer (CCOM), and the central computer (CCOM) responds to the request to the network of the public computer (PCOM). Execute the operation required for booting. The storage unit 244 of the network-booted public computer PCOM, for example, a hard disk drive is initialized by being overwritten with the above-described OS image file (S120). The initialized public computer PCOM is turned off and is processed in a standby mode (S130).

Then, when the second user turns on to use the corresponding public computer (PCOM) (YES in S140), the public computer (PCOM) likewise requests the central computer (CCOM) to boot the network having priority by BIOS setting. The central computer (CCOM) bypasses the request for network booting from the public computer (PCOM) that has already been initialized (S150). However, the present invention is not limited thereto, and the central computer CCOM may transmit a null value to the requested public computer PCOM. The central computer CCOM may maintain information on whether each public computer PCOM has been initialized.

The public computer (PCOM), which has been denied network booting, performs a hard disk drive booting having the next rank by BIOS setting (S160). That is, by executing the operating system on the initialized hard disk drive, the second user can use the public computer (PCOM).

As such, the method 100 for initializing the operating system of a public computer and the computing system 200 applying the same according to an embodiment of the present invention include an operating system installed on a hard disk drive of a public computer used by an unspecified number of people and a program installed on the operating system After the first user finishes using it, it can automatically and automatically initialize it before the second user uses it to remove the data used by the first user to protect personal information and other risk factors such as computer viruses. It may not be left to the user. Nevertheless, by using an operating system installed on a hard disk drive directly connected to the main board of a public computer (PCOM), unlike a system based on network storage such as ISCSI SAN, it can operate stably even through unexpected upgrades of the operating system. Can be. For example, operating systems such as Microsoft Windows do not consider operating on network storage, and thus various problems may occur during use. For example, when using the network booting method, a problem such as a failure to boot after a Windows upgrade may occur. In addition, when using an operating system installed on a hard disk drive directly connected to the main board of a public computer (PCOM), operation speed is improved or installation and maintenance are easier than using an operating system on network storage. Can provide.

The present invention is not limited to the above-described embodiments, and it is obvious to those skilled in the art to which the present invention pertains that various substitutions, modifications, and modifications are possible without departing from the technical spirit of the present invention. something to do. For example, in the above description, the initialization of the operating system of the public computer has been described, but the initialization of the startup program and the like along with the operating system of the public computer may also be performed with the same technical idea as the present invention.
