Description

Technical Field

[0001] This application relates to the field of servers, and in particular to a method, apparatus, and medium for resetting virtual machine passwords. Background Technology

[0002] With the development of cloud computing technology, more and more users are choosing to upload their data and services to cloud computing platforms. Currently, OpenStack is commonly used to manage virtual machines and provide cloud computing services to users. Cloud-Init is a setup process provided by the OpenStack platform. It executes virtual machine initialization setup tasks during the first startup after a virtual machine is created. After the initialization setup tasks are completed, a run record is generated in a fixed directory. This run record corresponds to the virtual machine's Universally Unique Identifier (UUID), indicating that the Cloud-Init process has successfully run on the virtual machine corresponding to that UUID.

[0003] When a virtual machine operating system crashes and cannot be repaired, the initial image is typically used to restore and rebuild the virtual machine. To restore as much of the virtual machine's attribute information as possible, the initial image used is often a snapshot of the original virtual machine. The UUID of the virtual machine remains the same before and after reconstruction. The rebuilt virtual machine system retains the running records of Cloud-Init within the virtual machine corresponding to that UUID, making it impossible to execute the Cloud-Init process again. This causes the virtual machine initialization setup to fail, preventing the user from resetting the virtual machine password. If the user forgets the virtual machine password, the virtual machine cannot be started, affecting the user's normal work.

[0004] Therefore, providing a virtual machine password reset method to prevent virtual machine initialization settings from failing and password reset due to the Cloud-Init process failing to execute after virtual machine reconstruction, thereby improving the reliability and security of virtual machines, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The purpose of this application is to provide a virtual machine password reset method, apparatus, and medium to prevent virtual machine initialization settings from failing and virtual machine passwords from being reset due to the Cloud-Init process failing to execute after rebuilding a virtual machine using a virtual machine image snapshot, thereby improving the reliability and security of the virtual machine.

[0017] Determine whether the second identifier is included in the nova database of the OpenStack platform;

[0018] If the second identifier exists, then the step of modifying the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain the reconstructed snapshot is performed.

[0019] Preferably, after the step of determining whether the Nova database of the OpenStack platform includes the second identifier, the method further includes:

[0020] If the second identifier does not exist, then add the second identifier to the nova database, with the initial value of the second identifier being the universally unique identifier;

[0021] An interface function is created based on the second identifier, enabling the OpenStack platform to call the corresponding virtual machine through the second identifier.

[0022] Preferably, before the step of obtaining the reconstruction image file corresponding to the reconstruction instruction, the method further includes:

[0023] Determine whether the current time meets the preset conditions;

[0024] If the preset conditions are met, create the virtual machine image snapshot for the initial virtual machine.

[0025] Preferably, after the step of updating the password of the rebuilt virtual machine according to the password reset instruction, the method further includes:

[0026] Determine whether a password reset success signal from the Cloud-Init process has been received within the threshold time.

[0027] If the password reset success signal is not received, a warning message will be sent to the administrator.

[0028] To address the aforementioned technical issues, this application also provides a virtual machine password reset device, applied to virtual machines under the OpenStack platform, comprising:

[0029] The acquisition module is used to acquire the reconstructed image file corresponding to the reconstruction instruction when a reconstruction instruction is detected;

[0030] The determination module is used to determine whether the reconstructed image file is a virtual machine snapshot;

[0031] The modification module is used to modify the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain a reconstructed snapshot if it is the virtual machine snapshot.

[0036] This application provides a virtual machine password reset method applied to virtual machines under the OpenStack platform. The method includes: when a rebuild command is detected, obtaining a rebuild image file corresponding to the rebuild command to rebuild the virtual machine based on the rebuild image file; determining whether the rebuild image file is a virtual machine snapshot; if it is, modifying the first identifier of the virtual machine corresponding to the virtual machine snapshot to obtain a rebuild snapshot.

The rebuilt virtual machine is created based on the rebuild snapshot, and the virtual machine initialization process is invoked to reset the password of the rebuilt virtual machine. Therefore, the virtual machine password reset method provided in this application, by setting a first identifier and a second identifier inside the virtual machine and modifying the first identifier when creating the rebuilt virtual machine using the initial virtual machine image snapshot, enables the Cloud-Init process to run in the rebuilt virtual machine to reset the password.

[0037] In addition, this application also provides a virtual machine password reset device and medium, which correspond to the above method and have the same effect. Attached Figure Description

[0042] Figure 4This is a structural diagram of a virtual machine password reset device provided in another embodiment of this application. Detailed Implementation

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0044] The core of this application is to provide a virtual machine password reset method, device, and medium to prevent virtual machine initialization settings from failing and virtual machine passwords from being reset due to the Cloud-Init process failing to execute after rebuilding a virtual machine using the original virtual machine image snapshot, thereby improving the reliability and security of the virtual machine.

[0045] During server operation, users may forget their virtual machine passwords. To prevent this, the password can be reset by rebuilding the virtual machine. To preserve user data as much as possible, a snapshot of the image created by the user can be used to rebuild the virtual machine. However, resetting the virtual machine password requires starting a virtual machine initialization process, which cannot be executed in a virtual machine that has already run this process, causing the password reset to fail. To solve this problem, this application provides a virtual machine password reset method. This method involves setting a first identifier and a second identifier within the virtual machine, and modifying the first identifier when rebuilding the virtual machine using an initial virtual machine image snapshot. This allows the virtual machine initialization process to run in the rebuilt virtual machine to reset the password. The first identifier is a universally unique identifier for the initial virtual machine, enabling the Cloud-Init program to run in the newly created virtual machine after the first identifier changes. The second identifier is a unique identifier for the initial virtual machine within the OpenStack platform, allowing users to access the virtual machine within the OpenStack platform using the second identifier.

[0046] The technical solution provided in this application is applied to servers running the OpenStack platform. It should be noted that this solution is illustrated using the server architecture of the Intel platform, but the method is not limited to servers on the Intel platform, nor is it limited to server systems. It still has general application value on server systems or other computer systems.

[0047] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Figure 1A flowchart of a virtual machine password reset method provided in this application embodiment is shown below. Figure 1 As shown, the method includes:

[0049] S10: When a reconstruction command is detected, obtain the reconstruction image file corresponding to the reconstruction command.

[0050] S11: Determine whether the reconstructed image file is a virtual machine snapshot.

[0051] In practice, when a user-sent rebuild command is detected, the virtual machine rebuild process is initiated, and the rebuild image file used to rebuild the virtual machine is obtained. It can be understood that the rebuild image file can be a blank image file corresponding to the initial virtual machine, or a snapshot of the virtual machine saved during its use.

[0052] It is important to note that since the virtual machine initialization process used for password reset is the Cloud-Init process, it generates an unmodifiable runtime log in a specified directory within the virtual machine after completing its initial tasks. When this runtime log exists, the Cloud-Init task cannot be executed again upon restarting the virtual machine. In this embodiment, when a blank image file is used to perform the virtual machine reconstruction task, the runtime log of the Cloud-Init task does not exist in the virtual machine system, allowing the password reset process to proceed. However, when a virtual machine snapshot is used to perform the reconstruction task, the corresponding runtime log exists in the virtual machine system, requiring the password reset scheme provided in this application to reset the password. Therefore, it is necessary to determine the reconstruction image file used to rebuild the virtual machine to determine the subsequent procedures.

[0053] S12: If it is a virtual machine snapshot, modify the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain the reconstructed snapshot. The initial virtual machine has a first identifier and a second identifier. The first identifier is the universally unique identifier of the initial virtual machine, and the second identifier is the unique identifier of the initial virtual machine in the OpenStack platform.

[0054] S13: Create a rebuild virtual machine based on the rebuild snapshot, and call the virtual machine initialization process to reset the password of the rebuild virtual machine.

[0055] In the OpenStack system, to ensure that each virtual machine can function properly, it is necessary to create a different unique identifier for each virtual machine. The Cloud-Init runtime log is a log file generated based on this unique identifier. To address this issue, this embodiment sets an additional identifier (UID) in the virtual machine. The first identifier is the initial virtual machine's universally unique identifier (UUID), so that the Cloud-Init program can run in a newly created virtual machine after the first identifier changes. The second identifier is the initial virtual machine's unique identifier (UID) within the OpenStack platform, allowing users to access the virtual machine in the OpenStack platform using the second identifier.

[0056] In practice, the first identifier is used to ensure that underlying applications and processes in the virtual machine system can execute according to the first identifier, thereby ensuring that the virtual machine can function normally. The second identifier is a unique identifier for the virtual machine within the OpenStack platform, used by users or administrators to operate on the virtual machine processes through the OpenStack platform.

[0057] In practice, the second identifier UID is used to uniquely identify a virtual machine. When the virtual machine is not rebuilt, the value of this field is the same as the original first identifier UUID. At this time, the two fields can identify a virtual machine at the same time. When the virtual machine performs a rebuild operation, the original first identifier UUID value is modified to a new UUID value, while the second identifier UID remains unchanged. In this way, the virtual machine has a new UUID value after rebuilding. When the virtual machine recognizes the new UUID value, it will normally execute the password reset task. The password reset can be successfully executed, thus realizing the function of resetting the virtual machine password during the rebuild process.

[0058] Figure 2 A timing diagram for creating a virtual machine based on a snapshot, as provided in this application embodiment, is shown below. Figure 2 As shown, the process of creating a virtual machine includes:

[0059] S20: Obtain the reconstruction command sent by the user, and determine the target virtual machine corresponding to the command based on the first identifier UUID in the user's reconstruction command, and obtain the relevant information of the target virtual machine;

[0060] S21: Obtain the target image required to rebuild the virtual machine according to the rebuild command. The target image includes a blank image and a virtual machine snapshot.

[0061] S22: Update the Instance table of the OpenStack platform;

[0062] S23: Add a UID field and related interface functions to the instance table;

[0063] S24: Send an RPC request to the Nova_scheduler process to select the compute node to mount and rebuild the virtual machine;

[0064] S25: Synchronize the updated Instance table to the Nova_compute process;

[0065] S26: Obtain the image file corresponding to the first identifier UUID, and send the image file to glance;

[0066] S27: Update the task list (task_state) of the Nova_compute process;

[0067] S28: Destroy the instance table in the libvirt process;

[0068] S29: Update the memory table (vm_state) and task table (task_state) in the OpenStack platform database.

[0069] This embodiment provides a virtual machine password reset method applied to virtual machines under the OpenStack platform. The method includes: when a rebuild command is detected, obtaining a rebuild image file corresponding to the rebuild command to rebuild the virtual machine based on the rebuild image file; determining whether the rebuild image file is a virtual machine snapshot; if it is, modifying the first identifier of the virtual machine corresponding to the virtual machine snapshot to obtain a rebuild snapshot. The virtual machine has a first identifier and a second identifier. The first identifier is a universally unique identifier for the initial virtual machine, allowing the Cloud-Init program to run in the newly created virtual machine after the first identifier changes; the second identifier is a unique identifier for the initial virtual machine within the OpenStack platform, allowing users to call the virtual machine in the OpenStack platform using the second identifier. A rebuilt virtual machine is created based on the rebuild snapshot, and the virtual machine initialization process is invoked to reset the password of the rebuilt virtual machine. Therefore, the virtual machine password reset method provided in this application, by setting a first identifier and a second identifier inside the virtual machine and modifying the first identifier when creating a rebuilt virtual machine using an initial virtual machine image snapshot, enables the Cloud-Init process to run in the rebuilt virtual machine to reset the password.

[0070] In a preferred embodiment, before modifying the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain the reconstructed snapshot, the method further includes:

[0071] Determine whether the Nova database on the OpenStack platform contains a second identifier;

[0072] If a second identifier exists, then the step of modifying the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain the step of rebuilding the snapshot is performed.

[0073] If a second identifier does not exist, it will be added to the nova database, with its initial value being a universally unique identifier. An interface function will be created based on this second identifier so that the OpenStack platform can call the corresponding virtual machine using it.

[0074] In a preferred embodiment, after modifying the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain the reconstructed snapshot, the method further includes:

[0075] Update the first identifier in the relational database, where the relational database is a database that stores the correspondence between the first identifier and the second identifier.

[0076] In practice, the OpenStack platform uses UID to call virtual machines with corresponding UUIDs to execute tasks. Therefore, the mapping between UIDs and UUIDs needs to be stored in a relational database to ensure that the virtual machines can work properly.

[0077] Furthermore, the process of adding a second identifier, UID, to the virtual machine includes:

[0078] (1) Extend the OpenStack nova database by adding a UID field to the instances table of the OpenStack nova database to uniquely identify a virtual machine. Its initial value is the value of the first identifier UUID of the current virtual machine.

[0079] (2) Extend the virtual machine nova service data operation interface to adapt to the extended instances table, and add new interfaces to the instances table to ensure that OpenStack platform users or administrators can read and write table records through the second identifier UID field.

[0080] (3) Extend the object item of the nova project, add a new attribute second identifier UID to the Instance object class, and add the corresponding interface get_by_UID. This interface can ensure that the virtual machine instance can be obtained through the UID of the user or administrator of the OpenStack platform.

[0081] (4) Modify the OpenStack nova_api service to rebuild the virtual machine interface. In the original processing flow, add the following processing logic: regenerate the virtual machine UUID and write the new UUID to the database for storage.

[0082] (5) Modify the remaining part of the rebuild process, changing the logic of using UUID to identify the virtual machine to use the new field UID.

[0083] (6) Modify the interfaces for querying, modifying, deleting, pausing, suspending, and resetting virtual machines to allow users to perform the above operations on virtual machines using the virtual machine UID.

[0084] (7) Modify the virtual machine creation interface. When creating a virtual machine, use the first identifier UUID of the virtual machine as the value of the second identifier UID and save it to the database. By default, the values ​​of the first identifier UUID and the second identifier UID are the same. When the virtual machine is rebuilt, the value of the first identifier UUID will be modified to make the values ​​of the first identifier UUID and the second identifier UID different.

[0085] Based on the above embodiments, resetting and rebuilding the virtual machine password by calling the virtual machine initialization process includes: executing the Cloud-Init process to obtain the password reset instruction entered by the user; and updating the password of the rebuilt virtual machine according to the password reset instruction.

[0086] Cloud-init is a tool specifically developed for initializing virtual machines in cloud environments. It reads relevant data from various data sources and configures the virtual machine accordingly. Common data sources include cloud platform metadata services and ConfigDrive. Common configurations include setting the virtual machine's hostname, hosts file, username and password, updating the apt-get local cache, and adjusting the file system size.

[0087] It's important to note that to ensure normal user operation, it's also necessary to verify whether the password was successfully reset. After updating and rebuilding the virtual machine's password according to the password reset command, the process also includes: determining whether a password reset success signal from the Cloud-Init process was received within a threshold time; if no password reset success signal is received, an alert is sent to administrators.

[0088] It should be noted that, in order to prevent data loss during the use of virtual machines, in addition to the above embodiments, it is also necessary to create snapshots for each virtual machine in each backup cycle to back up data and files.

[0089] In a preferred embodiment, before obtaining the reconstruction image file corresponding to the reconstruction instruction, the method further includes: determining whether the current time meets a preset condition; if the preset condition is met, creating a virtual machine image snapshot for the initial virtual machine. The backup period can be a fixed period set by the user, or a variable period determined based on data changes or business pressure (e.g., when data changes exceed a threshold, or when business pressure exceeds a threshold, a virtual machine snapshot needs to be created to back up the data to prevent data loss due to virtual machine failure).

[0090] The virtual machine password reset method has been described in detail in the above embodiments. This application also provides embodiments corresponding to the virtual machine password reset device. It should be noted that this application describes the embodiments of the device part from two perspectives: one is based on the functional module, and the other is based on the hardware.

[0095] Create module 13 to create a rebuild virtual machine based on the rebuild snapshot and call the virtual machine initialization process to reset the password of the rebuild virtual machine.

[0096] In addition, the virtual machine password reset device provided in this embodiment also includes: an identifier update module, an identifier judgment module, a database update module, a snapshot creation module, and an early warning module;

[0097] The identifier update module is used to update the first identifier in the relational database, where the relational database is a database that stores the correspondence between the first identifier and the second identifier.

[0098] The identifier determination module is used to determine whether the Nova database of the OpenStack platform includes a second identifier; if a second identifier exists, the module executes the step of modifying the first identifier of the initial virtual machine corresponding to the virtual machine snapshot to obtain the step of rebuilding the snapshot.

[0099] The database update module is used to add a second identifier to the nova database if the second identifier does not exist. The initial value of the second identifier is a universally unique identifier. It also creates interface functions based on the second identifier so that the OpenStack platform can call the corresponding virtual machine through the second identifier.

[0100] The snapshot creation module is used to determine whether the current time meets the preset conditions; if the preset conditions are met, a virtual machine image snapshot is created for the initial virtual machine.

[0101] The early warning module is used to determine whether a password reset success signal from the Cloud-Init process has been received within a threshold time. If no password reset success signal is received, an early warning message is sent to the administrator.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
