Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without any creative effort belong to the protection scope of the present application.
The core of the application is to provide a method, a device and a medium for resetting the virtual machine password, so as to prevent the failure of the initialization setting of the virtual machine and the failure of resetting the virtual machine password due to the fact that the Cloud-Init process cannot be executed after the virtual machine is reconstructed by using the original virtual machine mirror image snapshot, and improve the reliability and the safety of the virtual machine.
In the working process of the server, the user may forget the password of the virtual machine, and in order to prevent the problem, the user password may be reset in a manner of rebuilding the virtual machine. In order to preserve user data as much as possible, the virtual machine may be rebuilt using a mirror snapshot created by the user during use. However, resetting the virtual machine secret code requires starting the virtual machine initialization process, which cannot be executed in the virtual machine that has executed the process, resulting in a failure in resetting the virtual machine secret code. In order to solve the problem, the application provides a virtual machine code resetting method, which enables a virtual machine initialization process to run in a rebuilt virtual machine to reset a code by setting a first identifier and a second identifier inside the virtual machine and modifying the first identifier when the rebuilt virtual machine is created by using an initial virtual machine image snapshot. The first identifier is a universal unique identifier of the initial virtual machine, so that the Cloud-Init program can run in the newly-built virtual machine after the first identifier is changed; the second identifier is a unique identifier of the initial virtual machine in the OpenStack platform, so that a user can call the virtual machine in the OpenStack platform through the second identifier.
The technical scheme provided by the application is applied to a server running with an OpenStack platform, and it should be noted that the scheme is described by using a server architecture of an Intel platform, but the method is not limited to the server of the Intel platform and is not limited to a server system, and the method still has a general application value on server systems of other platforms or other computer systems.
In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.
Fig. 1 is a flowchart of a method for resetting a virtual secret code according to an embodiment of the present disclosure, as shown in fig. 1, the method includes:
s10: and when the reconstruction instruction is detected, acquiring a reconstruction image file corresponding to the reconstruction instruction.
S11: and judging whether the reconstructed mirror image file is a virtual machine snapshot or not.
In specific implementation, when a reconstruction instruction sent by a user is detected, a virtual machine reconstruction process is started, and a reconstruction image file used for reconstructing the virtual machine is obtained. It can be understood that the reconstructed image file may be a blank image file corresponding to the initial virtual machine, or may be a virtual machine snapshot stored in the use process of the initial virtual machine.
It should be noted that, since the virtual machine initialization process used for resetting the password is a Cloud-Init process, after the initial task is completed, a running log which cannot be modified is generated under a specified directory in the virtual machine, and when the running log exists, the virtual machine cannot execute the Cloud-Init task again when being started again. In this embodiment, when the blank mirror image file is used to execute the virtual machine rebuilding task, the running log of the Cloud-Init task does not exist in the virtual machine system, and the password resetting process can be executed; when the virtual machine snapshot is used for executing the reconstruction task, the corresponding running log exists in the virtual machine system, and the password can be reset only by using the password resetting scheme provided by the application. Therefore, the reconstructed image file used by the reconstructed virtual machine needs to be judged to determine the subsequent flow.
S12: if the virtual machine snapshot is obtained, modifying a first identifier of an initial virtual machine corresponding to the virtual machine snapshot to obtain a reconstructed snapshot, wherein the initial virtual machine has the first identifier and a second identifier, the first identifier is a universal unique identifier of the initial virtual machine, and the second identifier is a unique identifier of the initial virtual machine in an OpenStack platform;
s13: and creating a reconstructed virtual machine according to the reconstructed snapshot, and calling a virtual machine initialization process to reset the password of the reconstructed virtual machine.
In the OpenStack system, in order to ensure that each virtual machine can be normally used, different unique identifiers need to be created for each virtual machine, and the running log of the Cloud-Init is a log file generated according to the unique identifiers. In order to solve the problem, an additional identifier (UID) is set in the virtual machine in the embodiment, wherein the first identifier is a Universally Unique Identifier (UUID) of the initial virtual machine, so that the Cloud-Init program can run in the newly-built virtual machine after the first identifier is changed; the second identifier is a Unique Identifier (UID) of the initial virtual machine in the OpenStack platform, so that a user can call the virtual machine in the OpenStack platform through the second identifier.
In a specific implementation, the first identifier is used to ensure that underlying applications and processes in the virtual machine system can be executed according to the first identifier, so as to ensure that the virtual machine can work normally. The second identifier is a unique identifier of the virtual machine in the OpenStack platform, and is used for a user or a manager to operate the virtual machine process through the OpenStack platform.
In specific implementation, the second identifier UID is used for uniquely identifying one virtual machine, when the virtual machine does not perform reconstruction operation, the value of the field and the first identifier UUID of the original field take the same value, at this time, two fields can simultaneously identify one virtual machine, and when the virtual machine performs reconstruction operation, the original first identifier UUID value is modified into a new UUID value, and the second identifier UID is unchanged, so that the virtual machine has the new UUID value after reconstruction, the virtual machine internally recognizes the new UUID value, the task of resetting the password can be normally performed, the resetting password can be successfully performed, and the function of resetting the password of the virtual machine in the reconstruction process is realized.
Fig. 2 is a timing diagram of creating a virtual machine based on a snapshot according to an embodiment of the present application, and as shown in fig. 2, a process of creating a virtual machine includes:
s20: acquiring a reconstruction instruction sent by a user, calling and determining a target virtual machine corresponding to the instruction according to a first identifier UUID in the user reconstruction instruction, and acquiring related information of the target virtual machine;
s21: and acquiring a target image required by the virtual machine reconstruction according to the reconstruction instruction, wherein the target image comprises a blank image and a virtual machine snapshot.
S22: updating an Instance table of the OpenStack platform;
s23: adding a UID field and a related interface function into an instance table;
s24: sending an RPC request to a Nova _ scheduler process to select a computing node for mounting and reconstructing a virtual machine;
s25: synchronizing the updated Instance table to the Nova _ computer process;
s26: acquiring a mirror image file corresponding to the first identifier UUID, and sending the mirror image file to a company for processing;
s27: updating a task list (task _ state) of the Nova _ computer process;
s28: destroying an instance table in a libvirt process;
s29: and updating a memory table (vm _ state) and a task table (task _ state) in the OpenStack platform database.

And creating a reconstructed virtual machine according to the reconstructed snapshot, and calling a virtual machine initialization process to reset the password of the reconstructed virtual machine.

And is arranged at

and updating the first identifier in a relational database, wherein the relational database is a database for storing the corresponding relation between the first identifier and the second identifier.
In specific implementation, the OpenStack platform calls a virtual machine with a UUID corresponding to the UID through the UID to execute a task, so that the corresponding relationship between the UID and the UUID needs to be stored in a relational database to ensure that the virtual machine can work normally.
Further, the process of adding the second identifier UID to the virtual machine includes:
(1) And expanding the OpenStack nova database, and adding an UID field in an instances table of the OpenStack nova database, wherein the UID field is used for uniquely identifying one virtual machine, and the initial value of the UID field is the value of the first identifier UUID of the current virtual machine.
