Example one
Fig. 1 is a flowchart of a cross-room mirror synchronization method according to an embodiment of the present invention. The embodiment is applicable to the case of performing mirror synchronization on a plurality of computer rooms, and the method may be executed by the device for mirror synchronization across computer rooms provided in the embodiment of the present invention, where the device may be implemented by hardware and/or software, and may be generally integrated in a computer device, and the computer device may specifically be a service center. As shown in fig. 1, the method specifically comprises the following steps:
s11, determining a first number of machines in all the machine rooms, and determining a first target machine room to manufacture target images in all the machine rooms according to the first number.
Specifically, at the beginning of the method, the machine, that is, the server, may first determine a first number of machines providing services in each machine room, then determine to obtain a first target machine room according to the first number, and provide the first target machine room to the administrator to make a target mirror (that is, a required mirror), so that the first target machine room may be used as a first synchronization source. Each machine room may need to provide a large amount of services for users, the provision of the services has network requirements, and the public network bandwidth of the machine room needs to be occupied, meanwhile, because the machine rooms have a cross-cloud condition, the cross-cloud machine rooms are synchronized only to go through the public network, and a high probability also causes that the services provided by the machine rooms are unavailable, and then the machine rooms with a first smaller number may be specifically determined as first target machine rooms, so as to further reduce the influence on the service services. Optionally, the determining, according to the first number, a first target machine room in all the machine rooms to manufacture a target mirror image includes: and determining the machine room with the smallest first number in all the machine rooms as the first target machine room so as to reduce the influence on the business service as much as possible, and specifically, obtaining the first target machine room by sequencing the first number (for example, from a small number to a large number).
S12, inquiring the second number of machines in each machine room to be synchronized, and determining a second target machine room in the machine rooms to be synchronized according to the second number.
Specifically, after the first target machine room is determined and the target mirror image is manufactured or a synchronization process is completed, a second number of machines providing services in each machine room to be synchronized may be queried, and then a second target machine room is determined according to the second number, so that one machine room from the machine rooms to be synchronized may be selected as a synchronization object, where the machine room to be synchronized is a machine room that has not been synchronized in all the machine rooms. As described above, the machine room with the smaller second number may be specifically determined as the second target machine room, so as to further reduce the influence on the business service. Optionally, the determining a second target machine room in the machine rooms to be synchronized according to the second number includes: and determining the machine room with the minimum second number in the machine rooms to be synchronized as the second target machine room so as to reduce the influence on the business service as much as possible, and specifically, sorting the second number (for example, from a small number to a large number) to obtain the second target machine room.
S13, inquiring a third number of machines in each synchronization source machine room which already has the target mirror image, and determining a third target machine room in the synchronization source machine room according to the third number, wherein the synchronization source machine room comprises the first target machine room.
Specifically, after the second target machine room is determined, the third number of machines providing services in each synchronization source machine room may be queried, and then the third target machine room is determined according to the third number, so that one machine room may be selected from the synchronization source machine rooms as a synchronization source, where the synchronization source machine room is a machine room having a target mirror image in all the machine rooms, and specifically may include a first target machine room where the target mirror image is initially made, a second target machine room where synchronization is completed, and the like, and when the third target machine room is initially determined, the third target machine room is the first target machine room. As described above, the third target machine room may be determined as a machine room with a smaller third number, so as to further reduce the influence on the business service. Optionally, the determining a third target machine room in the synchronization source machine room according to the third number includes: and determining the machine room with the minimum third number in the synchronization source machine room as the third target machine room so as to reduce the influence on the service as much as possible, and specifically, obtaining the third target machine room by sorting the third number (for example, from a small number to a large number).
Optionally, the querying a third number of machines in each synchronization source machine room that already has the target mirror, and determining a third target machine room in the synchronization source machine room according to the third number includes: determining a target synchronization source machine room which is the same as the cloud manufacturer of the second target machine room in the synchronization source machine room; and inquiring the fourth quantity of the machines in each target synchronous source machine room, and determining the third target machine room in the target synchronous source machine room according to the fourth quantity. Specifically, when the second target machine room is synchronized, a machine room in the synchronization source machine room, which is the same as the cloud manufacturer of the second target machine room, may be preferentially selected, so as to further reduce the influence on the service. The target synchronization source machine rooms identical to the cloud manufacturer of the second target machine room may be determined in all the synchronization source machine rooms, and then the fourth number of machines providing services in each target synchronization source machine room is queried, so as to determine and obtain the third target machine room according to the fourth number. Specifically, each synchronous source machine room can be firstly grouped according to a cloud manufacturer, each group is sorted according to the number of machines, and then the group which is the same as the cloud manufacturer of the second target machine room is 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 the synchronous source machine room is updated at each subsequent time, a newly added synchronous source machine room can be added into the corresponding group and inserted into the sorting result according to the number of machines, so that the sorting process at each time is saved.
Further optionally, the querying a third number of machines in each synchronization source machine room that already has the target mirror, and determining a third target machine room in the synchronization source machine room according to the third number, further includes: and if the target synchronous source machine room does not exist in the synchronous source machine room, determining a third target machine room in the synchronous source machine room according to the third quantity. Specifically, if there is no target synchronization source room in all synchronization source rooms that is the same as the cloud manufacturer of the second target room, the third target room may be determined directly according to the third number of machines in each synchronization source room, and the specific process is described above and will not be described in detail here.
And S14, performing target mirror synchronization on the second target machine room by taking the third target machine room as a synchronization source, and returning to execute the step S12 until the synchronization of all machine rooms is completed.
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 perform target mirror synchronization on the second target machine room. After the synchronization is completed, the second target machine room may be updated from the machine room to be synchronized to the synchronization source machine room, and then the step S12 is executed to re-determine the second target machine room and the third target machine room to perform synchronization until the synchronization of all the machine rooms is completed.
Optionally, the synchronizing the target mirror image of the second target machine room with the third target machine room as a synchronization source includes: and sending a synchronization source request to the synchronization service of the second target machine room through the third target machine room. Further optionally, after the sending, by the third target machine room, a synchronization source request to the synchronization service of the second target machine room, the method further includes: adding the second target machine room into a synchronous task queue information table; and inquiring the synchronous task queue information table according to a preset period to determine the synchronization condition of the second target machine room until synchronization is completed. 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 send a synchronization source request to a synchronization service of the second target machine room so as to request synchronization, meanwhile, after synchronization is started, the second target machine room can be added into the synchronization task queue information table, then, the synchronization condition of the second target machine room can be checked by continuously inquiring the synchronization task queue information table according to a preset period, such as the stepping degree, whether synchronization is successful or not, and the like, until synchronization is completed, the second target machine room can be updated to be the synchronization source machine room, and can be removed from the synchronization task queue information table.

Specifically, after the first target machine room which can be used as the synchronization source and the second target machine room which is synchronized are obtained, the corresponding machine rooms can be added into the synchronization source list, so that a third target machine room which is newly used as the synchronization source can be determined from the synchronization source list in the following process.
According to the technical scheme provided by the embodiment of the invention, the first number of machines in all the machine rooms is determined, the first target machine room is determined to manufacture the target mirror image in all the machine rooms according to the first number, then the second number of the machines in each machine room to be synchronized and the third number of the machines in each synchronization source machine room are respectively inquired, the second target machine room is determined in the machine rooms to be synchronized according to the second number, the third target machine room is determined in the synchronization source machine room according to the third number, so that the third target machine room is used as a synchronization source to synchronize the target mirror image of the second target machine room, and the determining process and the synchronizing process of the second target machine room and the third target machine room are repeated until the synchronization of all the machine rooms is completed.
