Method and system for automatically installing operating system, and media that can record computer program sources

The present invention relates to a control system and method for automatically installing an operating system on a client host (server to be installed) remotely and to a recording medium recording a program source thereof, and more specifically, without a process of checking MAC address information of a host. It is about a system and method that can quickly install the operating system, and separately manage information on the installation history to easily control the installation of the operating system for a plurality of hosts, and a recording medium recording the program source.

In a network environment with multiple host computers, a cluster system may be used to remotely install an operating system by a management host when a problem occurs in an operating system of a client host and requires reinstallation or upgrade.

In such a cluster system, in case of serious problem in operating system caused by virus or cracking on multiple client hosts simultaneously, it is possible to remotely control by the management host without having to reinstall the operating system for one client host. It is recognized for its efficiency as a system that improves security by repairing or upgrading the damage of the operating system.

Referring to FIG. 1, the configuration of a conventional cluster system is briefly described. A conventional cluster system includes a management host 10 including a Dynamic Host Configuration Protocol (DHCP) server 11 and a Trivial File Transfer Protocol (TFTP) server 12. And a client host 20 including a PreBoot Execution Environment (PXE) server 21.

The DHCP server 11 is necessary for the PXE client host 20 to obtain an IP address, the PXE server 21 is necessary to support network booting, and the TFTP server 21 transmits a source of an operating system. Do this.

1 shows a procedure of a method for remote automatic installation of an operating system according to the present invention. In order to perform remote installation of the operating system, the target client host 20 needs to be assigned an Internet address. Therefore, the MAC address of the network interface card (NIC) mounted on the target client host 20 is installed. ) Should be aware of in advance.

As shown in FIG. 1, the management host 10 first powers on a remote client host 20 using a wake-on-lan. The powered on client host 20 detects the DHCP server 11 of the management host 10 (①), and the DHCP server 11 of the management host is connected to the PXE server 21 of the client host 20. Assign an IP address (②).

Thereafter, the client host 10 assigned the IP address requests the bstrap.0 file from the TFTP server 12 of the management host 10. The TFTP server 12 of the management host transmits the bstrap.0 file in response to the client host's request. The client host then chooses a remote installation. Next, the client host 20 requests an installation image from the management host 10, and in response to the request, the management host transmits the installation image to the client host, wherein the TFTP is a distribution CD image. Mount or copy to a suitable directory and then export (③).

For example, as illustrated in FIG. 1, the Red Hat Linux distribution creates a file under the '/ kickstart /' directory 22 for each client host 20 under the name '<host IP addr> -kickstart'.

After this process is completed, if you set the network boot as the top priority in the BIOS setup of the client host to be installed and reboot, you can boot the configured kernel and ramdisk to install the operating system.

The remote network installation method of the operating system as described above is convenient to manage a plurality of client hosts, but when the operating system is already installed through network booting when the operating system is automatically installed, due to a hardware problem or a disk fail If the reboot is performed because the operating system is not normally loaded, there is a problem that the operating system is repeatedly installed through the network boot.

In addition, if the BIOS setting is set to network booting in a state in which the operating system is normally installed due to a mistake and a lack of confirmation due to the administrator's negligence in management, in such a case, the operating system may be repeatedly installed.

In addition, in the related art, in order to install an operating system on a client host, the management host must know the MAC address information of the client host to be installed in advance, and the trouble of requiring the manual input of such information to the management host in advance. there was.

In addition, when the operating system is properly installed on the client host, the administrator, not the management host, checks the settings of each client host to change the BIOS settings so that network booting does not occur.

Accordingly, an object of the present invention is to prevent the repeated installation of the operating system by repeated network boot for the reboot of the hardware problem due to a hardware problem in the remote automatic installation of the operating system for the client host or the setting of the BIOS due to the neglect of management of the administrator. have.

In addition, the installation history management unit may store the details and success values in a database to increase the ease of installation history management and statistical data collection and management.

Hereinafter, with reference to the drawings will be described in detail with respect to the system and method for automatic remote control installation of the operating system according to the present invention, and a recording medium storing the program source.

First, the remote operating system for automatically installing the operating system according to the present invention is connected to the client host 200 where the operating system is to be installed and the client host 200 as shown in FIG. 2 through a network boot to install the operating system. It may be configured as a management host 100 to control. At this time, the management host 100 is a DHCP server 101 for automatically distributing IP for accessing the network to the client host 200, and TFTP server 102 for transmitting the initial boot image and the configuration file to the client host 200 It can be configured as.

In addition, the present invention further includes an installation history management unit 300, based on the information transmitted from the management host 100 and the client host 200, installation information (cause of installation of the operating system, installation statistics), the installation state ( Installation request, installation cancellation, installation, installation completed, installation failure) or the installation of the operating system can be determined whether the installation was successful, and can store the relevant information.

When the remote operating system remote installation process is described in detail based on the above configuration, the client host 200 is configured to set the boot route to network boot through BIOS setup so that a network card 201 supporting network booting through the PXE protocol is installed. Turn on the power of the client host 200 to connect to the DHCP server 101 of the management host 100 or transmit the Wake-On-Lan signal from the management host 100 to the client host 200 to remotely start the installation request. (①) In this case, the PXE protocol may support data exchange between the DHCP 101 and the TFTP server 102 and the client host 200, including a DHCP and a TFTP protocol, and a network card as a communication means supporting the PXE protocol. But not limited thereto.

Based on the installation request, the management host 100 automatically registers registration information on the MAC address information and the installation request time of the installation request target client host 200 (②), and switches to the standby mode to the administrator. Inform the registration information about the client host 200 in which the installation request was made (③). Detailed description of the process from the automatic registration to the notification of the registration information will be described below.

On the other hand, if the administrator determines that the installation of the operating system is required for the target client host 200 based on the registration information (④), the management host 100 is based on the input information of the administrator (the client host ( 200 transmits network information so as to access the DHCP server 101 of the management host 100 through the DHCP protocol (⑤). The network information includes IP information distributed by the DHCP server 101 to the client host 200.

When the connection to the management host 100 is made through the network information, the management host 100 transmits the kernel image and the kickstart configuration file through the TFTP server 102 so that automatic installation is performed (⑥).

When the transmission of the kernel image and the configuration file is completed, the client host 200 is rebooted and control is passed to the kernel through the kickstart configuration file 202 installed on the client host. Follow the procedure to install the operating system.

On the other hand, the DHCP server 101 of the management host 100 is installed by the operating system transmits the installation history for the response operation with the client host 200 and the transmission operation process of the kernel image to the installation history management unit 300 in real time. You can record the status or notify the administrator in real time (⑦).

In addition, the client host 200 identifies and accesses the address of the server of the installation history management unit 300 through the configuration file, thereby installing the installation process through the kernel image and whether the installation is completed. By providing (⑧), the installation history management unit 300 may store the overall installation history information and provide it to the administrator.

3 is a flowchart illustrating an operation process in a management host according to the present invention, wherein the installation request step of the first client host may be performed by turning on the power of the client host to operate a network card supporting the PXE protocol or in the management host. The Wake-On-Lan signal is transmitted to the client host to be remotely activated to perform a network boot (S201).

Subsequently, the management host automatically registers and manages registration information on the MAC address information and the installation request time of the client host in the DHCP server, and the information on the client host on which the installation request is made to the administrator is stored. Notify through the installation request host is automatically registered step (S202). Through such steps, the administrator can avoid the inconvenience caused by manually inputting the registration information of the client host of the installation request target and the input error that can occur during the input process to the server of the management host. Can be provided.

On the other hand, when the registration step is completed, the management host does not immediately install the operating system through network booting, and the client host undergoes network booting due to a temporary hardware defect or incorrect BIOS setup under the control of an administrator through a standby mode. By going through the installation standby state switching step that is set to determine whether or not the operating system is repeatedly installed (S203), it is possible to solve the problem of unnecessary installation of the unnecessary operating system.

This standby mode may be implemented by the management host changing the protocol of the DHCP server so that IP assignment is not made to the client host.

Subsequently, when the administrator determines that a normal operating system installation of the client host is required, the management host controls installation of the DHCP server to perform IP assignment to the client host based on the registration information according to the input information of the manager. It may be step (S204).

Meanwhile, the switching of the standby mode may be implemented by changing the DHCP protocol as described above, which will be described in detail with reference to FIGS. 4 to 5.

4 to 5, first, the management host may receive a DHCP DISCOVER message of a client host (S301) to determine a target client host for an installation request. Thereafter, the management host sends a DHCP OFFER message (S302) to inform the client of the connection through the DHCP protocol.

Thereafter, the management host receives a DHCP REQUEST message, which is a request message for connecting to a predefined DHCP protocol, from the client host (S303). At this time, the management host leaves the received DHCP REQUEST Message packet as a file. Registration information regarding the MAC address, installation request time, etc. of the target client host where the installation request is made may be stored in the DHCP server (S304).

In this way, the management host may automatically assign IP to the target client host without the administrator manually inputting the MAC address into the DHCP server.

Subsequently, the administrator can be notified of the registration information so that the operating system can be installed according to the input information of the administrator, so that the target client can determine whether the installation of the operating system is required by the administrator before the operating system is installed. That is, the management host finally obtains the installation authority according to the administrator's input information, and converts the state to the standby mode before the administrator's input information is input (S305).

In the standby mode, as shown in FIG. 5, after the management host receives a DHCP REQUEST message, the management host changes the DHCP protocol to process a bad request without transmitting a DHCP ACK. Thus, the client host does not receive the DHCP ACK. It may be implemented by returning to the step of transmitting a message (S306).

Subsequently, when an input for starting installation is input to the management host by the administrator's input information, the management host adds a new message type of DHCP protocol to create an interface, and reads the registration information of the target client host until the client starts. By sending a DHCP ACK to the host to the IP assignment of the client host by the DHCP server (S307).

In addition, when the connection with the client host through the IP allocation is completed, the management host transmits a kernel image and a kickstart configuration file through the TFTP server to a target client host so that an OS installation through network booting is performed.

On the other hand, the management host and the installation history management unit can inform the administrator of the installation history information as described above to confirm the installation history and installation success of the client host, which will be described in detail with reference to FIG.

Referring to FIG. 6, the management host receives a message generated during the installation request process of the client host and various events generated during the loading process of the kernel image through the kickstart configuration file as a message from the client host. The information on the installation details may be recorded in an instant and provided to the installation history management unit (S401).

In addition, the installation history manager may store the received information on the installation history in a database. At this time, the information on the installation details may include the installation information and installation status when the installation request, the installation cancellation, the installation progress, the installation success, the installation failure (S403).

In addition, when the installation is successful, the client host returns a success value to the installation history managing unit by using an additional script to execute an additional script after the operating system is installed in the% post region of the kickstar configuration file. Information on whether the installation is successful may be stored in the database (S403).

The installation history information including information on the installation details and information on whether the installation is successful is transmitted to the administrator through email or SMS by searching the database whenever the installation history manager generates an event or at the request of an administrator. This can be informed by (S402).
