[0047] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0048] The names of messages or information exchanged between multiple devices in the embodiments of this disclosure are for illustrative purposes only and are not intended to limit the scope of such messages or information.

[0049] First, some nouns or terms that appear in the description of the embodiments of this application shall be interpreted as follows:

[0050] vCPU: Virtual CPU.

[0051] PE disk: A disk containing a preinstallation environment (PE) operating system.

[0052] OCR: Character Recognition.

[0053] NLP: Natural Language Processing.

[0054] GuestOS: User operating system.

[0055] Fstab file: describes information about various file systems and stores data on the correspondence between file systems and directory structures.

[0056] Starting an instance is the first unavoidable step for users to use a cloud server, and it's also a high-frequency, critical operation. Occasionally, instance startup will fail, and the reasons for this are quite complex. Starting an instance often involves the user's operating system running on the cloud server and other systems on the cloud platform. Many factors can cause the instance to fail to start, including user-related issues such as image version or OS configuration problems, as well as issues on the cloud platform side. In emergency situations, such problems can also disrupt corresponding services.

[0057] Based on the above background, in one embodiment, please refer to Figure 1 This embodiment provides a computer cluster system, including a cloud server and a cloud management system. The cloud management system is capable of executing cloud server diagnostic methods to diagnose the cloud server. In some embodiments, the cloud management system includes a diagnostic module, a query module, and multiple sub-modules; each sub-module stores module logs, and the cloud server depends on at least some of the sub-modules; the diagnostic module is capable of executing cloud server diagnostic methods to diagnose the cloud server; the query module is capable of responding to query requests initiated by the diagnostic module and querying the module logs of a target sub-module within a specified time range, where the target sub-module is a sub-module that the cloud server depends on.

[0058] Cloud servers can include functional components such as instances, images, block storage, security groups, snapshots, and networks. An instance is essentially a virtual server, containing basic computing components such as vCPU, memory, operating system, network configuration, and disk. An image is like a "installation disk," providing the instance with an operating system and pre-installed software. Block storage is a distributed data storage device used for data storage, allowing random read and write operations. A security group is a virtual firewall that divides security isolation zones and implements network access control. A snapshot is a real-time copy of a cloud disk at a specific point in time, used for data backup, recovery, application disaster recovery, and image creation. A network can be a Virtual Private Cloud (VPC), a logically completely isolated private network in the cloud.

[0059] Please see Figure 2This is a flowchart of a cloud server diagnostic method provided in this embodiment, which is used to run the method on... Figure 1 Taking the diagnostic module in the example, the steps are as follows:

[0060] Step S101: In response to the diagnostic request for the cloud server, perform the corresponding diagnostic task according to the operating status of the cloud server, including: if the cloud server is in the startup state, perform step S102; if the cloud server is in the shutdown state, perform step S103.

[0061] The user's operating system generates a diagnostic request based on user input and sends it to the diagnostic module. User input can include selecting a problem scenario, such as "the cloud server cannot start." Upon receiving the diagnostic request, the diagnostic module initiates a diagnostic scan of the cloud server. Considering that the cloud server's operational status affects the diagnostic results, the diagnostic module first determines the cloud server's operational status and then selects an online / offline diagnostic mode based on that status.

[0062] Step S102: Diagnose the cloud server based on the error information from the user operating system running on the cloud server.

[0063] With the cloud server running, the diagnostic module will select online diagnostic mode. The module will query the database for error information related to the user's operating system and the error messages. In some embodiments, the diagnostic module may also query the database for repair solutions associated with the user's operating system error information. This database is specifically designed for cloud server startup issues and stores error messages related to cloud server startup problems, user operating system error information, and repair solutions.

[0064] Step S103: Mount the pre-installed environment operating system on the cloud server, start the cloud server using the pre-installed environment operating system, and perform diagnostics on the cloud server under the pre-installed environment operating system.

[0065] When the cloud server is offline, the diagnostic module will select offline diagnostic mode. The module mounts a pre-installed operating system (e.g., the user's operating system on a PE disk) on the cloud server. After booting the cloud server using the PE disk, the diagnostic module sends diagnostic commands to the pre-installed operating system, which then executes the corresponding diagnostic scripts. The disk containing the user's operating system is mounted as a data disk on the cloud server, and the diagnostic scripts are used to diagnose the user's operating system on the data disk.

[0066] In steps S101 to S103 above, based on the cloud server's operating status, and combining online and offline diagnostic modes, the diagnostic capabilities for cloud server startup scenarios are enhanced; resources are concentrated on diagnosing cloud server startup problems, avoiding unnecessary resource waste from full-scale diagnostics and saving diagnostic time. Thus, this embodiment can diagnose cloud server startup problems in a centralized and efficient manner.

[0067] In some embodiments, after diagnosing the cloud server under the pre-installed environment operating system, the diagnostic module will uninstall the pre-installed environment operating system from the cloud server.

[0068] In one embodiment, after executing step S102 or S103, i.e., after completing the diagnosis of the cloud server, the diagnostic module will generate a diagnostic report. The diagnostic report includes diagnostic results, repair solutions, or a combination of both. The repair solutions include repair suggestion text, repair components, or a combination of both. The repair components can respond to user input and generate repair instructions for running repair scripts in the operating system currently running on the cloud server. Repair instructions, i.e., computer script commands, can be executed within the operating system. The repair instructions can be encapsulated into a one-click repair tool. If the user clicks the "One-Click Repair" button in the operating system interface, the diagnostic module sends the corresponding repair instructions to the operating system. After the operating system completes the repair instructions, it returns the repair results to the diagnostic module. Specifically, for example, if the user's grub file is missing, the one-click repair tool can help the user install a pre-installed operating system, then use the pre-installed operating system to boot the cloud server. After restoring the grub boot file, the pre-installed operating system can be uninstalled. This setup eliminates any learning curve for users, offers comprehensive functionality and automated operation, diagnoses numerous issues, and provides users with manual repair suggestions or automated repair methods, thus achieving a complete closed loop in the problem-solving process.

[0069] In one embodiment, diagnosing a cloud server based on error messages from the user's operating system running on the cloud server can be achieved as follows: obtaining a screenshot of the user's operating system when an error occurs, retrieving the error message from the screenshot, and identifying the problem in the user's operating system based on the error message. When a pop-up appears on the user's operating system screen, the cloud server's snapshot component can be used to capture a screenshot, which the user's operating system then uploads to the diagnostic module. The diagnostic module performs character recognition (OCR) on the screenshot and natural language processing (NLP) on the recognized text to obtain the error message.

[0070] Taking the error message "1662001135: Windows system entered recovery environment due to an error" as an example, the diagnostic module matches the error message with the database to obtain a predefined error code. Then, it provides the repair solution and error code to the client, which can then repair the system using the repair documentation. An example of the repair documentation is as follows: The "Problem Description" states, "The Windows system instance runs normally for an extended period, but after restarting, it cannot enter the user's operating system. When accessing the instance via VNC, the desktop displays the system recovery option. Using previously backed-up automatic snapshots to restore the Windows system also fails." The "Possible Causes" state, "The Windows system may have entered the Windows recovery environment. When the Windows user operating system encounters an error or fails to boot, it will enter the recovery environment. This can be caused by various reasons, including: corrupted user registry, disk problems, driver problems, corrupted or missing system files, corrupted BCD (Boot Configuration Data) files, user error, viruses, third-party antivirus software, and abnormal forced restarts." The "Solution" states, "Regarding the system entering repair mode, we recommend using the solutions suggested by Microsoft's official technical support. For specific instructions, please refer to HowWindowsREWorks. To avoid the computer entering the system recovery interface after restarting and to ensure the system can recover from the failure, you can refer to the following in daily use to avoid problems: Store important data on a data disk. Regularly take snapshots of the system disk and data disk so that data can be recovered in case of problems. Back up the registry file before modifying the system registry to avoid modifying system files. Regularly run Windows Update to ensure that the latest Microsoft security updates are installed. Enable cloud security center or other commercial antivirus protection tools on ECS. Perform regular antivirus scans and regularly update the antivirus software version."

[0071] In one embodiment, see Figure 3 This is a flowchart of another cloud server diagnostic method provided in this embodiment, which is implemented using this method. Figure 1 Taking the diagnostic module in the example, the steps are as follows:

[0072] Step S201: Receive a diagnostic request for the cloud server;

[0073] Step S202: Determine whether the cloud server is running; if yes, proceed to step S203; otherwise, proceed to step S204.

[0074] Step S203: Diagnose the cloud server based on the error information from the user operating system running on the cloud server;

[0075] Step S204: Mount the pre-installed environment operating system on the cloud server, start the cloud server using the pre-installed environment operating system, and perform diagnostics on the cloud server under the pre-installed environment operating system; after completing the current step, proceed to step S207.

[0076] Step S205: Determine whether the error message from the user's operating system indicates an abnormality in the user's operating system; if yes, proceed to step S207; otherwise, proceed to step S206.

[0077] Step S206: Set the cloud server to a shutdown state; after completing the current step, proceed to step S204.

[0078] Step S207: Generate a diagnostic report.

[0079] In this embodiment, online and offline diagnostics are combined, both of which diagnose the user's operating system running on the cloud server. First, an online diagnostic is performed on the user's operating system. If the online diagnostic detects an anomaly, a diagnostic report is generated. If the online diagnostic fails to detect an anomaly, an offline diagnostic is performed. If the offline diagnostic detects an anomaly, a diagnostic report is generated.

[0080] In one embodiment, another cloud server diagnostic method is provided, wherein the cloud server is provided by a cloud platform, the cloud platform includes a cloud management system, and the cloud server depends on the cloud management system. The cloud server diagnostic method in this embodiment includes the following steps:

[0081] The diagnostic module responds to diagnostic requests for the cloud server and performs corresponding diagnostic tasks based on the cloud server's operating status. These tasks include: when the cloud server is running, diagnosing the cloud server based on error messages from the user operating system running on the cloud server; when the cloud server is shut down, retrieving logs from the cloud management system within the cloud platform; diagnosing the cloud platform based on the cloud management system logs; and generating a diagnostic report.

[0082] In some embodiments, the cloud management system includes multiple sub-modules, each storing module logs. Obtaining the cloud management system logs in the cloud platform includes: responding to a query request initiated by a client, obtaining the module logs of a target sub-module within a specified time range, wherein the target sub-module is a sub-module on which the cloud server depends.

[0083] In this embodiment, online diagnostics and cloud platform diagnostics are combined. Online diagnostics diagnose the user operating system of the cloud server, while cloud platform diagnostics diagnose the various sub-modules of the cloud management system on the cloud platform side. This approach provides diverse methods for locating problems and comprehensive coverage of issues.

[0084] In one embodiment, another cloud server diagnostic method is provided, wherein the cloud server is provided by a cloud platform, the cloud platform includes a cloud management system, and the cloud server depends on the cloud management system. The cloud server diagnostic method in this embodiment includes the following steps:

[0085] The diagnostic module responds to diagnostic requests for the cloud server and performs corresponding diagnostic tasks based on the cloud server's operating status. These tasks include: when the cloud server is in a downtime state, the diagnostic module mounts a pre-installed operating system on the cloud server, starts the cloud server using the pre-installed operating system, and performs diagnostics on the cloud server under the pre-installed operating system; the diagnostic module retrieves logs from the cloud management system in the cloud platform; performs diagnostics on the cloud platform based on the logs from the cloud management system; and the diagnostic module generates a diagnostic report.

[0086] In some embodiments, the cloud management system includes multiple sub-modules, each storing module logs. Obtaining the logs of the cloud management system in the cloud platform includes: in response to a query request to the cloud server, obtaining the module logs of a target sub-module within a specified time range, wherein the target sub-module is a sub-module on which the cloud server depends.

[0087] In one embodiment, another cloud server diagnostic method is provided, wherein the cloud server is provided by a cloud platform, the cloud platform includes a cloud management system, and the cloud server depends on the cloud management system. The cloud server diagnostic method in this embodiment includes the following steps:

[0088] The diagnostic module responds to diagnostic requests for the cloud server and performs corresponding diagnostic tasks based on the cloud server's operating status. These tasks include: if the cloud server is in a downtime state, the diagnostic module retrieves logs from the cloud management system within the cloud platform; performs diagnostics on the cloud platform based on the cloud management system logs; if the diagnosis indicates that the cloud management system is not abnormal, it mounts a pre-installed operating system on the cloud server, starts the cloud server using the pre-installed operating system, and performs diagnostics on the cloud server under the pre-installed operating system; and generates a diagnostic report.

[0089] In some embodiments, the cloud management system includes multiple sub-modules, each storing module logs. Obtaining the logs of the cloud management system in the cloud platform includes: in response to a query request to the cloud server, obtaining the module logs of a target sub-module within a specified time range, wherein the target sub-module is a sub-module on which the cloud server depends.

[0090] In one embodiment, see Figure 4 This is a flowchart of another cloud server diagnostic method provided in this embodiment, which is implemented using this method. Figure 1 Taking the diagnostic module in the example, the steps are as follows:

[0091] Step S301: Receive a diagnostic request for the cloud server;

[0092] Step S302: Determine whether the cloud server is running; if yes, proceed to step S303; otherwise, proceed to step S304.

[0093] Step S303: Diagnose the cloud server based on the error information from the user operating system running on the cloud server;

[0094] Step S304: Obtain the logs of the cloud management system in the cloud platform, and diagnose the cloud platform based on the logs of the cloud management system;

[0095] Step S305: Determine whether the error message from the user's operating system indicates an abnormality in the user's operating system; if yes, proceed to step S309; ​​otherwise, proceed to step S306.

[0096] Step S306: Set the cloud server to a shutdown state; after completing the current step, proceed to step S304.

[0097] Step S307: Determine whether there is an anomaly in the cloud management system; if yes, proceed to step S309; ​​otherwise, proceed to step S308.

[0098] Step S308: Mount the pre-installed environment operating system on the cloud server, start the cloud server using the pre-installed environment operating system, and perform diagnostics on the cloud server under the pre-installed environment operating system.

[0099] Step S309: Generate a diagnostic report.

[0100] In this embodiment, the diagnostic module responds to a query request to the cloud server by obtaining the module logs of the target sub-module within a specified time range. The target sub-module is the sub-module on which the cloud server depends.

[0101] In this embodiment, online diagnostics, offline diagnostics, and cloud platform diagnostics are combined. Both online and offline diagnostics involve diagnosing the user's operating system running on the cloud server, while cloud platform diagnostics involves diagnosing each sub-module of the cloud management system on the cloud platform side.

[0102] First, an online diagnostic is performed on the user's operating system on the cloud server. If the online diagnostic detects an anomaly in the user's operating system, a diagnostic report is returned to the client. If the online diagnostic fails to detect an anomaly in the user's operating system, a diagnostic is performed on the cloud platform. If the cloud management system is found to be faulty, a diagnostic report is returned to the client. If the cloud management system is functioning normally, an offline diagnostic is performed on the user's operating system on the cloud server. If the offline diagnostic detects an anomaly in the user's operating system, a diagnostic report is returned to the client. After completing these three processes—online diagnostic, cloud platform diagnostic, and offline diagnostic—if any problem is detected in any of the intermediate processes, the diagnostic process is terminated, and a diagnostic report and a repair plan are presented to the client.

[0103] This embodiment describes a diagnostic method for cloud server startup problems. It includes not only diagnosing the user's operating system running on the cloud server but also diagnosing the cloud platform itself, helping users comprehensively identify, locate, and resolve issues. The combination of offline and online diagnostics provides diverse problem-solving methods and comprehensive coverage. The targeted diagnostic set ensures clear user guidance and avoids wasting the diagnostic system's resources on meaningless diagnoses, saving both resources and diagnostic time. It can help users automatically repair problems and quickly restore system operation.

[0104] In one embodiment, see Figure 5 This embodiment provides an interactive principle diagram combining cloud platform diagnosis and offline diagnosis, such as... Figure 5 As shown, the diagnostic module first sends a query request to the query module. The query module searches for module logs within a specified time range in each submodule of the cloud management system. After the search is complete, it returns the search results to the diagnostic module. If the diagnostic module finds an anomaly in the cloud management system, it generates a diagnostic report, prompting the user to seek technical support from the cloud platform and sending an internal alarm. If the management system problem is resolved, the diagnostic module mounts a system repair disk (i.e., the pre-installed environment operating system) on the user's operating system (GuestOS). The cloud server is then started in repair mode using the system repair disk, with the user's original system disk mounted as a data disk. After the cloud server starts, the system repair disk reports a heartbeat to the diagnostic module. Upon receiving the heartbeat information, the diagnostic module sends diagnostic commands to the cloud server. The system repair disk runs the diagnostic commands on the user's original system disk and returns the results to the diagnostic module. Based on the returned diagnostic results, the diagnostic module generates a corresponding diagnostic report for the user, including repair suggestions or a one-click repair tool. If the user chooses one-click repair, the diagnostic module sends the corresponding repair commands to the cloud server. After the cloud server runs the repair commands, it returns the repair results to the diagnostic module. The diagnostic module uninstalls the system repair disk from the user's operating system.

[0105] For example, when a non-existent device appears in the device file Fstab of a Linux system, the Linux system loads the Fstab file during boot and loads devices according to the file. If the device does not exist, the system will freeze and report an error, failing to boot. The diagnostic module will first diagnose problems with the cloud platform. If no problems are found, it will mount a system repair disk on the cloud server to boot it in repair mode, and then run a fault detection program to perform a comprehensive check. If a non-existent device is found in the Fstab file, the module will obtain the error information and report it to the diagnostic module. After receiving the error information, the diagnostic module will return it to the user and provide corresponding repair solutions. If the cloud platform has the capability, it will also provide the user with a one-click repair tool.
