Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making any inventive effort are within the scope of the present invention.
The invention aims to provide a method, a device, equipment and a medium for synchronizing versions of a virtualization system so as to solve the technical problem of operation and maintenance risks brought by the fact that different versions of the virtualization system are managed together.
In order to better understand the aspects of the present invention, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. Fig. 1 is a flowchart of a method for synchronizing versions of a virtualized system according to an embodiment of the present invention, as shown in fig. 1, where the method includes:
s101, after receiving the version synchronization request, acquiring an image file of the virtualization system with the target version corresponding to the version synchronization request.
It should be noted that, the execution main body of the virtualization system version synchronization method provided by the invention can be a main platform of a virtualization system with different architectures and different versions of nanotubes, and can also be understood as a main platform of homologous heterogeneous nodes with different versions of nanotubes.
When executing step S101, after receiving the version synchronization request, the main platform may parse the target version to be synchronized according to the version synchronization request. And uploading the image file package of the virtualization system with the target version to an image library of the main platform so as to enable the main platform to acquire the image file of the virtualization system with the target version. These image files may contain complete configuration and state information of the virtualized system for subsequent synchronization and self-healing operations.
Assuming that the target version is 6.0 version, the versions of heterogeneous virtualization systems of different versions comprise 4.5 version, 5.0 version, 5.5 version, 6.0 version and the like, and the purpose of the invention is to synchronize the versions of heterogeneous virtualization systems to 6.0 version so as to solve the technical problem of operation and maintenance risks caused by the fact that the virtualization systems of different versions are managed together.
S102, scanning and synchronizing environment information of the heterogeneous nodes to obtain information of the heterogeneous virtualization system.
After the image file is acquired, step S102 needs to be executed, where the environment information of each heterogeneous node to be synchronized is scanned and synchronized to the host platform, so as to obtain the information of the heterogeneous virtualization system. The resulting information of the heterogeneous virtualized system includes the hardware configuration of the nodes, the operating system, the application version, and other relevant system information. This information will be synchronized to the host platform for subsequent comparison.
S103, repairing the information of the heterogeneous virtualization system according to a comparison result between the information of the heterogeneous virtualization system and the mirror image file.
After the information of the image file and the heterogeneous virtualization system is acquired, the process of comparing and identifying self-repair of step S103 needs to be performed. The heterogeneous virtualization systems corresponding to other versions (such as version 4.5, version 5.0 and version 5.5) different from the target version must be distinguished from the information of the target version (such as version 6.0), and according to the comparison result, the place needing to be repaired can be found out, so that the heterogeneous virtualization systems corresponding to other versions different from the target version can reach the requirement of synchronizable, and the later synchronization operation can be performed.
S104, synchronizing the target version to the repaired heterogeneous virtualization system.
In practice, after the completion of the above-described preparation work, the synchronization operation of step S104 may be started to be performed. Step S104 may be understood as synchronizing the target version information on the primary platform to each of the heterogeneous nodes, where the synchronization may include file synchronization, data backup and recovery, and so on. After performing steps S101 to S104, the master platform hosting the homologous heterogeneous nodes of different versions has completed synchronizing all nodes to the unified version of nodes.
In the method for synchronizing the versions of the virtualized system provided by the embodiment of the invention, the versions of the virtualized systems with different frameworks are synchronized, so that the synchronization function among the different versions is realized, the version difference among the different systems is pulled through, the operation and maintenance risks caused by the version difference are reduced, the virtualized system information with different frameworks is self-repaired before synchronization, the stability and the reliability of the systems are ensured, and the system faults and the performance reduction caused by the hardware difference are reduced.
In a specific implementation, in the above method for synchronizing a version of a virtualized system provided by the embodiment of the present invention, step S103 may repair information of a heterogeneous virtualized system according to a comparison result between the information of the heterogeneous virtualized system and an image file, which may specifically include: comparing the information of the heterogeneous virtualization system with the mirror image file; judging whether the heterogeneous virtualization system meets the synchronization condition according to the comparison result; if the synchronization condition is met, directly synchronizing the target version to the heterogeneous virtualization system; if the synchronization condition is not satisfied, the information of the heterogeneous virtualization system needs to be repaired.
In implementation, the determining whether the heterogeneous virtualization system meets the synchronization condition in the above step may specifically include:
judging whether the partition names of the heterogeneous virtualization system in the directory structure are consistent with the partition names in the mirror image file or not;
if the partition names are inconsistent, judging that the heterogeneous virtualization system does not meet the synchronization condition;
if the partition names are consistent, judging whether the storage state of the heterogeneous virtualization system is consistent with the storage state in the mirror image file;
if the storage states are inconsistent, judging that the heterogeneous virtualization system does not meet the synchronization condition;
if the storage states are consistent, judging whether the disk states of the heterogeneous virtualization system are consistent with the disk states in the mirror image file;
if the states of the disks are inconsistent, judging that the heterogeneous virtualization system does not meet the synchronization condition;
if the states of the disks are consistent, judging whether the states of the virtual machines of the heterogeneous virtualization system are consistent with the states of the virtual machines in the mirror image file;
if the states of the virtual machines are inconsistent, judging that the heterogeneous virtualization system does not meet the synchronization condition;
if the virtual machine states are consistent, judging whether the memory of the heterogeneous virtualization system is consistent with the memory in the mirror image file;
if the memories are inconsistent, judging that the heterogeneous virtualization system does not meet the synchronization condition;
if the memories are consistent, judging whether the network of the heterogeneous virtualization system is consistent with the network in the mirror image file;
if the networks are inconsistent, judging that the heterogeneous virtualization system does not meet the synchronization condition;
and if the networks are consistent, judging that the heterogeneous virtualization system meets the synchronization condition.
That is, the invention can sequentially check the partition, the storage state, the disk state, the virtual machine state, the memory, the network and the like of the heterogeneous virtualization system to judge whether the heterogeneous virtualization system meets the synchronization condition, so as to further improve the synchronization effect.
Of course, if the synchronization condition only needs to check any one or more of the partition, the storage state, the disk state, the virtual machine state, the memory and the network, or the checking sequence changes, the judging content and the judging sequence can be adjusted according to the actual situation, and the method is not limited herein.
In addition, in the embodiment of the present invention, in the above-mentioned method for synchronizing the version of the virtualized system, since various problems may be encountered in the process of synchronizing the version, step S103 repairs the information of the heterogeneous virtualized system, which may specifically include the following cases:
repairing the information of the heterogeneous virtualization system until the synchronous condition is met;
when the known compatibility problem, loophole or file change problem exists in the information of the heterogeneous virtualization system, the information of the heterogeneous virtualization system is correspondingly repaired.
In implementation, in order to solve these problems, it is necessary to identify a self-repairing problem and perform corresponding processing, and when identifying that the information of the heterogeneous virtualized system has a known compatibility problem, a vulnerability or a file modification problem, the corresponding repairing is performed on the information of the heterogeneous virtualized system, which may specifically include the following cases:
the first case is that when the information of the heterogeneous virtualization system is identified to have file conflict, a conflict resolution method is adopted for repairing;
the second case is when the information of the heterogeneous virtualization system is identified to have a data inconsistency problem, and a data backup and recovery mechanism is adopted for repairing.
In addition to the two cases, the method can also finish corresponding repair according to the mode of automatically updating, restarting or repairing tools and the like according to the identified corresponding problems. After the self-repairing related problems are identified, risks caused by different structural differences of the homologous heterogeneous virtualization system can be reduced, the probability of problem faults is reduced, the usability of the system is ensured, and meanwhile, the stability and the robustness of the system are improved.
It should be noted that, in the above-mentioned method for synchronizing a version of a virtualized system according to the embodiment of the present invention, before synchronization, a synchronization rule may also be determined for a heterogeneous virtualized system, for example: and checking whether the heterogeneous virtualization system has synchronous permission or not, and whether migration synchronization, virtual machine starting synchronization and other rules are met. When a system to be synchronized requires a set synchronization rule, it can be checked whether the system meets the synchronization rule, and if the system does not meet the synchronization rule, the related problems are solved before synchronization, for example: if the system needs to meet the rule of the synchronous permission and does not meet the rule at present, a certain method is needed to be adopted to enable the system to meet the rule of the synchronous permission; if the system needs to meet the rule of migration synchronization, it does not meet the rule of migration synchronization currently, and a certain method needs to be adopted to enable the system to meet the rule of migration synchronization.
In a specific implementation, the method for synchronizing the version of the virtualized system provided by the embodiment of the invention may further include: monitoring the heterogeneous virtualization system in the synchronization process to monitor the execution condition of the synchronization operation; and recording the monitoring result containing the repair file, and carrying out data backup on the original file.
The above steps are that in the process of version synchronization, a synchronization monitoring recording function needs to be started to monitor and record the heterogeneous virtualization system, monitor the execution condition of the synchronization operation, and record the monitoring result, including each step of synchronization, a data change point, a repair file and the like. And at the same time of recording, the original file can be subjected to related data backup for subsequent rollback operation with failed synchronization. Thus, the rollback of the synchronous failure environment is ensured, an administrator is helped to find and solve the problem in time, and the stability and the reliability of synchronous operation are ensured.
In a specific implementation, the method for synchronizing the version of the virtualized system provided by the embodiment of the invention may further include: if the synchronization fails or is wrong in the synchronization process, the corresponding node with the synchronization failure or the synchronization mistake carries out rollback operation.
In practice, if a serious problem is found during synchronization, a rollback operation needs to be performed to restore the system to a pre-synchronization state. Rollback operations may include restoring files and data that failed in synchronization, repairing misconfigurations, restoring system state, restoring configuration files, backing up data, and so forth. By rollback operation, the stability and reliability of the system can be ensured, the homologous heterogeneous nodes can be restored to the state before synchronization to ensure the sustainable operation of the system, the risk brought by service interruption caused by synchronization is reduced, and the occurrence of system breakdown or performance degradation caused by synchronization errors is avoided.
The invention can synchronize the versions of the homologous heterogeneous nodes and repair the self-problems in the homologous heterogeneous virtualization system, thereby improving the stability and reliability of the system and reducing the operation and maintenance cost and risk. By executing the steps, unified management and maintenance of virtualization systems with different architectures and versions can be realized, the availability and performance of the system are improved, and powerful support is provided for business continuity and development of enterprises.
