[0002] Currently, based on the server side, a virtual operating system infrastructure (VOI) desktop is usually deployed to manage terminal devices, and the VOI desktop system is started by using the terminal devices.

[0003] However, when the VOI desktop system is damaged, it is impossible to enter the desktop, and the current device cannot be put into a usable state, which seriously affects user use. Summary of the invention

[0004] The embodiment of the present disclosure provides a diskless disaster recovery method and device, which can enable the VOI desktop system to be loaded normally when it is damaged. The technical solution is as follows:

[0006] Specifically, through the blockchain network management service on each node, in the blockchain network, each node performs network monitoring in the target area, that is, monitors whether the DHCP service and TFTP service in the target area are running normally, thereby ensuring that there are normally running DHCP services and TFTP services in the target area. Among them, the above-mentioned blockchain network management service is started on the target server side by default.

[0007] Start the DHCP service and TFTP service through the selected target terminal device, and ensure that there is only one DHCP service in the target area.

[0034] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0035] Currently, based on the server side, the management of terminal devices usually deploys VOI desktops and starts the VOI desktop system by utilizing the terminal devices.

[0036] However, when the VOI desktop system is damaged, it is impossible to enter the desktop, and the current device cannot be put into a usable state, which seriously affects user use.

[0037] In view of this, the present disclosure provides a diskless disaster recovery method, which can improve the above problems and enhance user experience.

[0038] It should be understood that in the following embodiments, as an example, a cloud computing server, a terminal device, a VOI desktop system, and a diskless boot system may be included.

[0039] The present disclosure provides a diskless disaster recovery method 100. Figure 1 As shown, the diskless disaster recovery method includes the following steps:

[0040] S101, monitor whether the DHCP service and TFTP service in the target area are running normally through the blockchain network management service of the target server.

[0041] Specifically, through the blockchain network management service on each node, in the blockchain network, each node performs network monitoring in the target area, that is, monitors whether the DHCP service and TFTP service in the target area are running normally, thereby ensuring that there are normally running DHCP services and TFTP services in the target area. Among them, the above-mentioned blockchain network management service is started on the target server side by default.

[0042] In a possible embodiment, the target server is a cloud computing server.

[0043] S102, when the DHCP service or the TFTP service runs abnormally, a target terminal device is selected from multiple terminal devices through the blockchain network management service.

[0044] Specifically, a target terminal device can be selected from multiple terminal devices within the target area through the blockchain network management service.

[0045] For example, if there is an abnormality in the operation of the DHCP service or the TFTP service, the blockchain network management service can conduct an election in the target area and select a terminal device from multiple terminal devices as the target terminal device. Furthermore, the multiple terminal devices are all in the target area.

[0046] S103, starting the DHCP service and the TFTP service through the target terminal device.

[0047] The DHCP service is unique in the target area.

[0048] Specifically, the DHCP service and TFTP service are started by the selected target terminal device, and it is ensured that there is only one DHCP service in the target area. After the newly added terminal device is started, the blockchain network management service will automatically add the target terminal device to the target area.

[0049] S104, when the VOI desktop of the target terminal device fails to start, start the VOI desktop through PXE.

[0050] Specifically, starting the VOI desktop through PXE includes:

[0051] Use the IPMI tool to guide the target terminal device into the PXE stage;

[0052] Obtain the file used for system startup through the DHCP server;

[0053] Load the files used for system startup into the memory, mount and start the VOI desktop system.

[0054] Furthermore, in the above solution, obtaining the file for system startup through the DHCP server includes:

[0055] Send request information by broadcasting;

[0056] Based on the request information, verify the legitimate TFTP server in the target area through the blockchain network management service;

[0057] Receive feedback from the blockchain network management service, including the address of the appropriate Internet Protocol IP, PXE boot file, and TFTP server;

[0058] Obtain the file used for system startup through the target terminal device based on the PXE startup file and the TFTP server.

[0059] Specifically, when the target terminal device fails to start the VOI desktop system, the IPMI tool can be used to guide the target terminal device into the PXE stage; then, the request information is sent by broadcasting. After the DHCP server receives the request information from the target terminal device, the blockchain network management service verifies the legitimate TFTP server in the target area; then, feedback information is sent to the target terminal device through the blockchain network management service, and the feedback information includes a reasonable IP, PXE startup file and the address of the TFTP server; then; the target terminal device that enters the PXE stage obtains the file for system startup (i.e., the file required for system startup) according to the PXE startup file and the TFTP server; finally, after obtaining the above files, they are loaded into the memory, and the VOI desktop system is mounted at the same time, and the VOI desktop system is finally started.

[0060] It should be understood that in the above scheme, if the request information fails to be sent by broadcasting, for example, all DHCP services in the target area are abnormal, then log out directly; only when there is a normally operating DHCP service, the step of verifying the legitimate TFTP server in the target area by the blockchain network management service in the above scheme will be executed.

[0061] Optionally, the method 100 may further include:

[0062] Initialize the device; start the blockchain network management service.

[0063] The devices include multiple terminal devices and a target server.

[0064] Specifically, before step S110, the method may also include preparing the initial deployment of the target server and multiple terminal devices, including pre-installing DHCP service, TFTP service, blockchain network management service, VOI desktop system and diskless boot system, and adding IPMI tools for multiple terminal devices. After that, the blockchain network management service is enabled. Furthermore, multiple terminal devices are all within the target area.

[0065] It should be understood that in another possible solution, when the target terminal device successfully starts the VOI desktop, it can directly enter the VOI desktop system.

[0066] Figure 2 2 is a flowchart of a desktop system startup method 200 provided by the present disclosure embodiment.
