Here, the Cloud is made up of a large number of hosts or web servers based on Cloud Computing (Cloud Computing), which is a type of distributed Computing, one virtual computer consisting of a collection of loosely coupled computers.
Fig. 1 is a flowchart of a file synchronization method based on an operation and maintenance auditing system according to an embodiment of the present application, where the method includes step S101, step S102, step S103, step S104, and step S105.
Step S101, the FILE service module of the first network device sends synchronization information to the HA service module.
The FILE service module is used for executing operations on FILEs, and the HA service module is used for providing interface services for data synchronization. For example, the FILE service module may provide actual operations on FILEs, and it may directly perform operations such as adding rights. The HA service module can receive file information which needs to be synchronized by the device, and can also receive heartbeat information sent by the Peer service module.
In some embodiments, the FILE service module of the first network device sends the synchronization information to the HA service module through the synchronization API interface. For example, as shown in fig. 2, the first network device may be the host B in fig. 2, and the host B sends the information to be synchronized (i.e. the synchronization information) to the HA service module through the synchronization API interface provided in the host B.
In some embodiments, the synchronization information includes type information of a synchronization operation. For example, as shown in fig. 2, the information that needs to be synchronized (i.e., the synchronization information) sent by the host B to the HA service module through the synchronization API interface provided within the host B contains at least a specific type of synchronization operation. All subsequent operations may be customized based on different types.
Step S102, the HA service module of the first network device analyzes and stores the synchronization information.
For example, as shown in fig. 2, after receiving data sent through the API interface, the HA service module checks the data, and stores the data that is checked to be valid using a queue.
Step S103, when the HA service module of the first network device receives the heartbeat request message sent by the PEER service module of the second network device, returns a heartbeat response message to the PEER service module of the second network device, where the heartbeat response message includes the synchronization information.
For example, the PEER service module is configured to obtain file information that needs to be synchronized from an HA service module of the PEER network device. For the synchronization information, the PEER service module of the second network device (e.g., the host a in fig. 2) is required to send a heartbeat request message to obtain the synchronization information, and after receiving the heartbeat request message, the HA service module of the first network device (e.g., the host B in fig. 2) extracts a certain amount of synchronization information from the synchronization queue and returns the synchronization information to the PEER service module of the second network device (e.g., the host a in fig. 2).
Step S104, the PEER service module of the second network device parses the heartbeat response message, encapsulates the operation that cannot be directly executed by the device into a synchronization request message, and sends the synchronization request message to the SYN service module of the second network device.
For example, after receiving the heartbeat response message, the PEER service module of the second network device (e.g., host a in fig. 2) first parses the response message packet, and then immediately executes some operations that can be directly executed on the device after parsing. As shown in fig. 2, the remaining operations are encapsulated and sent to the SYN service module via a synchronization request message. The SYN service module is configured to receive file synchronization information filtered by the PEER service module, where the file synchronization information needs to be obtained by interacting with an opposite terminal or is effective when being executed on the opposite terminal, for example, file synchronization, directory deletion, file permission, and the like.
Step S105, the SYN service module of the second network device and the FILE service module of the first network device execute an operation corresponding to the synchronization request message together in an interactive manner.
For example, the SYN service module of the second network device (e.g., host a in fig. 2) and the FILE service module of the opposite end (i.e., the first network device, e.g., host B in fig. 2) complete related operations related to the FILE in an interactive manner. It should be noted that the message processing flow described in fig. 2 is performed by interaction between the host a and the host B, and the figure does not show the entire interaction content of the host a and the host B.
In some embodiments, as shown in fig. 2, the SYN service module of the second network device (e.g., host a in fig. 2) acquires a synchronization FILE based on the synchronization request message, sends a FILE synchronization request message to the FILE service module of the first network device (e.g., host B in fig. 2), and the FILE service module of the first network device (e.g., host B in fig. 2) returns a FILE synchronization response message to the SYN service module of the second network device (e.g., host a in fig. 2).
In some embodiments, as shown in fig. 3, the first network device (e.g., host B in fig. 3) includes an HA service module, a PEER service module, a SYN service module, and a FILE service module; the second network device (e.g., host a in fig. 3) includes an HA service module, a PEER service module, a SYN service module, and a FILE service module. Fig. 2 shows only a part of the process of the interaction between the PEER service module and the SYN service module of the host a and the HA service module and the FILE service module of the host B, and similarly, the PEER service module and the SYN service module of the host B may also interact with the HA service module and the FILE service module of the host a.
Fig. 4 is a schematic diagram of a network device for synchronizing FILEs according to an embodiment of the present application, where the network device includes an HA service module 401, a PEER service module 402, a SYN service module 403, and a FILE service module 404.
The HA service module 401 is configured to provide an interface service for data synchronization.
For example, the network device may include a host a and a host B in fig. 3, as shown in fig. 3, the host a and the host B are active and standby, and service information deployed by the active and standby hosts is completely consistent.
In some embodiments, the HA service module 401 is configured to receive file information that needs to be synchronized by the device, and receive heartbeat information sent by the PEER service module.
The PEER service module 402 is configured to obtain file information that needs to be synchronized from HA service modules of other network devices.
For example, the PEER service module is configured to periodically acquire file information to be synchronized from an HA service module of the PEER network device; the file information does not only refer to the specific file to be synchronized, and the file information may include, but is not limited to, the following information: creating directories, deleting directories, synchronizing files, deleting files, adding file permissions, adding file owners, and the like. For these different operations, a distinction can be made by different flag bits.
The SYN service module 403 is configured to receive the file synchronization information filtered by the PEER service module. For example, the synchronization information needs to be obtained interactively with the opposite terminal or be validated at the opposite terminal, such as synchronization of files, deletion of directories, deletion of files, authority of files, and the like.
The FILE service module 404 is used for executing operations on FILEs.
For example, the FILE service module provides actual operations on FILEs; if the file is a synchronous file, the file is opened by the synchronous file, and the read file is sent to the requested SYN service module; if the operation is the operation of adding the authority and the like, the operation is directly executed by the operation.
In some embodiments, the SYN service module and the FILE service module are in a multi-process or multi-threaded mode. For example, for an operation and maintenance auditing system, the pressure of FILE synchronization may be large, and therefore, the SYN service module and the FILE service module may be designed to be in a mode of supporting high concurrency, such as multi-process or multi-thread.
In summary, according to the embodiment of the application, for the operation and maintenance auditing system adopting the dual-computer structure, the file synchronization can be normally performed on the basis that the host computer and the standby computer normally provide services to the outside.
