[0047] Embodiment one

[0048] Figure 1 The flowchart of the cross-machine room mirroring synchronization method provided by the first embodiment of the present application. The present embodiment can be applied to the case of mirroring synchronization of multiple machine rooms. The method can be performed by the cross-machine room mirroring synchronization device provided by the embodiment of the present application. The device can be realized by hardware and / or software, and can be generally integrated in a computer device, which can be a service center in particular. As shown in Figure 1 The specific steps include the following steps:

[0049] S11, determine the first number of machines in all machine rooms, and determine a first target machine room to make a target mirror image according to the first number in all machine rooms.

[0050] Specifically, the machine, i.e., the server, can first determine the first number of machines providing services in each machine room at the beginning of the method, and then determine the first target machine room according to the first number, and provide the first target machine room to the administrator to make a target image (i.e., a required image), so that the first target machine room can be used as the first synchronization source. Each machine room can need to provide a large number of services to users, and providing services requires network demand and occupies the public network bandwidth of the machine room. At the same time, due to the existence of cross-cloud machine rooms, cross-cloud machine room synchronization can only go through the public network, which can also have a large probability to cause the services provided by the machine room to be unavailable. Therefore, the machine room with a smaller first number can be determined as the first target machine room to further reduce the impact on business services. Optionally, the method of determining the first target machine room to make a target image according to the first number in all machine rooms includes determining the machine room with the smallest first number in all machine rooms as the first target machine room to reduce the impact on business services as much as possible. Specifically, the first target machine room can be obtained by sorting the first numbers (e.g., from small to large).

[0051] S12, query the second number of machines in each machine room to be synchronized, and determine a second target machine room in the machine room to be synchronized according to the second number.

[0052] Specifically, after determining the first target machine room and making the target image, or after completing a synchronization process, the second number of machines providing services in each machine room to be synchronized can be queried, and then a second target machine room can be determined according to the second number, so that a machine room can be selected from the machine rooms to be synchronized as a synchronization object. The machine rooms to be synchronized are machine rooms that have not completed synchronization in all machine rooms. As described above, the machine room with a smaller second number can be determined as the second target machine room to further reduce the impact on business services. Optionally, the method of determining the second target machine room according to the second number in the machine room to be synchronized includes determining the machine room with the smallest second number in the machine room to be synchronized as the second target machine room to reduce the impact on business services as much as possible. Specifically, the second target machine room can be obtained by sorting the second numbers (e.g., from small to large).

[0053] S13, query the third number of machines in each synchronization source machine room that has the target image, and determine a third target machine room in the synchronization source machine room according to the third number, wherein the synchronization source machine room includes the first target machine room.

[0054] Specifically, after the second target machine room is determined, the third quantity of machines providing services in each synchronization source machine room can be queried, and then the third target machine room is determined according to the third quantity, so that a machine room can be selected from the synchronization source machine rooms as a synchronization source, wherein the synchronization source machine room is a machine room that has already owned the target image among all machine rooms, and specifically can include the first target machine room that initially makes the target image, the second target machine room that has completed synchronization, etc. The third target machine room is the first target machine room when initially determined. As described above, the machine room with a smaller third quantity can be specifically determined as the third target machine room to further reduce the impact on business services. Optionally, the third target machine room is determined in the synchronization source machine room according to the third quantity, including: determining the machine room with the smallest third quantity in the synchronization source machine room as the third target machine room to reduce the impact on business services as much as possible, and the third target machine room can be obtained by sorting the third quantity (such as from small to large).

[0055] Optionally, the third quantity of machines in each synchronization source machine room that has already owned the target image is queried, and the third target machine room is determined in the synchronization source machine room according to the third quantity, including: determining a target synchronization source machine room with the same cloud vendor as the second target machine room in the synchronization source machine room; querying the fourth quantity of machines in each target synchronization source machine room, and determining the third target machine room in the target synchronization source machine room according to the fourth quantity. Specifically, when synchronizing the second target machine room, the machine room with the same cloud vendor as the second target machine room in the synchronization source machine room can be preferentially selected to further reduce the impact on business services. Then the target synchronization source machine room with the same cloud vendor as the second target machine room can be first determined in all synchronization source machine rooms, and the fourth quantity of machines providing services in each target synchronization source machine room can be queried to determine the third target machine room according to the fourth quantity. As described above, the machine room with a smaller fourth quantity in the target synchronization source machine room can be determined as the third target machine room, and the machine room with the smallest fourth quantity can be further determined as the third target machine room to reduce the impact on business services as much as possible. Specifically, each synchronization source machine room can be grouped according to the cloud vendor first, and each group can be sorted according to the machine quantity, and then the group with the same cloud vendor as the second target machine room can be determined as the target group, so that the third target machine room can be determined according to the sorting result in the target group, and meanwhile, when updating the synchronization source machine room each time, the newly added synchronization source machine room can be added to the corresponding group and inserted into the sorting result according to the machine quantity to save the sorting process each time.

[0056] Further optionally, the query has a third number of machines in each of the target image's synchronization source machine rooms, and determines a third target machine room in the synchronization source machine rooms according to the third number, and the method further comprises: if the target synchronization source machine room does not exist in the synchronization source machine rooms, determining the third target machine room in the synchronization source machine rooms according to the third number. Specifically, if there is no target synchronization source machine room with the same cloud provider as the second target machine room in all the synchronization source machine rooms, the third target machine room can be determined directly according to the third number of machines in each of the synchronization source machine rooms, and the specific process is as described above, which is not repeated here.

[0057] S14, synchronizing the target image of the second target machine room by the third target machine room as a synchronization source, and returning to step S12 until the synchronization of all machine rooms is completed.

[0058] Specifically, after the second target machine room and the third target machine room are determined, the third target machine room can be used as a synchronization source to synchronize the target image of the second target machine room. After the synchronization is completed, the second target machine room can be updated from a machine room to be synchronized to a synchronization source machine room, and then step S12 is returned to determine the second target machine room and the third target machine room for synchronization again until the synchronization of all machine rooms is completed.

[0059] Optionally, the synchronizing the target image of the second target machine room by the third target machine room as a synchronization source comprises: sending a synchronization source request to a synchronization service of the second target machine room through the third target machine room. Further optionally, after the sending of the synchronization source request to the synchronization service of the second target machine room through the third target machine room, the method further comprises: adding the second target machine room to a synchronization task queue information table; and querying the synchronization task queue information table according to a preset period to determine the synchronization of the second target machine room until the synchronization is completed. Specifically, after the second target machine room and the third target machine room are determined, the third target machine room can send a synchronization source request to the synchronization service of the second target machine room as a synchronization source to request synchronization. After the synchronization starts, the second target machine room can be added to the synchronization task queue information table, and then the synchronization of the second target machine room, such as the synchronization progress and whether the synchronization is successful, can be checked by constantly querying the synchronization task queue information table according to a preset period until the synchronization is completed, and then the second target machine room can be updated to a synchronization source machine room and removed from the synchronization task queue information table.

[0060] On the basis of the technical scheme, optionally, after the first target machine room is determined to make the target image according to the first quantity in all machine rooms, the first target machine room is added to a synchronization source list; after the second target machine room is synchronized with the target image by taking the third target machine room as the synchronization source, the second target machine room is added to the synchronization source list, so as to determine the synchronization source machine room according to the synchronization source list. Specifically, after the first target machine room that can be the synchronization source and the second target machine room that is synchronized are obtained, the corresponding machine rooms can be added to the synchronization source list, so that the third target machine room that is newly taken as the synchronization source can be determined from the synchronization source list.

[0061] The technical scheme provided by the embodiment of the application first determines the first quantity of machines in all machine rooms, and determines a first target machine room to make a target image according to the first quantity in all machine rooms, then respectively queries a second quantity of machines in each machine room to be synchronized and a third quantity of machines in each synchronization source machine room, and determines a second target machine room in the machine room to be synchronized according to the second quantity, and determines a third target machine room in the synchronization source machine room according to the third quantity, so as to synchronize the second target machine room with the target image by taking the third target machine room as the synchronization source, and then repeats the determination process and the synchronization process of the second target machine room and the third target machine room until the synchronization of all machine rooms is completed. The technical scheme provided by the embodiment of the application cancels the limitation of the main machine room, determines the number of available servers in each machine room in real time, and selects appropriate synchronization sources and synchronization objects for synchronization, thereby avoiding the problem of fixed link, reducing the influence on the business service, avoiding the problem that the synchronization cannot continue due to the synchronization failure of a machine room, and realizing the fast and efficient synchronization mirroring for each machine room.
