The disks are independent, and the normal use of resources on other disks cannot be influenced by adding, deleting or damaging one disk.
When the resources are imported, the file type resources are registered by recording the paths or soft links of the file type resources; for the database type resources, importing the resources into a network target range platform database, simultaneously recording the unique number of the resource disk, and modifying the resource batch related to the resource disk number into an available state when the same resource disk number is recorded in the platform database; when the resources are stopped, clearing the path or soft link of the corresponding file resources for the file type resources; and for the database type resources, modifying the resource batch related to the resource disk number in the database into an unavailable state according to the unique number of the resource disk.

The detailed implementation steps of the embodiments of the present invention are further described below with reference to specific applications.
1. A resource production export module: responsible for generating the original resource disks from user input. The method comprises the following steps:
a. receiving manually input resource selection range (such as a course list), and automatically calculating other resources on which the selected resource depends; as shown in fig. 2, the resource categories mainly include virtual node images, topology maps, network traffic packages, software packages, course materials, course videos, course exercises, and the like; the dependency relationship among the resources mainly comprises the dependency of the course teaching materials on the course video, the dependency of the course teaching materials on the course problems, the dependency of the course teaching materials on the topological graph, the dependency of the topological graph on the virtual node mirror image, the dependency of the topological graph on the network traffic packet, the dependency among the virtual node mirror images (the dynamically constructed mirror image depends on the static mirror image), the dependency of the virtual node mirror image on the software packet, the dependency among the software packets and the like. The specific dependency relationship of each resource is stored in a database table or a resource file. For example, the course problem resource table describes the course materials associated with the problem via the foreign key field, while the software package resources describe the other software packages on which it depends via the metadata file of the software package.
b. And calculating the size of the disk space occupied by the selected resource and the dependent resource.
c. And receiving a manually input target disk, and checking whether the disk capacity is enough to accommodate the resources.
d. The disk is reinitialized and only one partition is created. The volume label of the partition adopts a uniform name (such as CRSRC, an abbreviation of Cyber Range Resource in English) and is used for a network shooting Range platform to preliminarily identify the content of the disk so as to decide whether to try to mount the disk to a directory and further detect the disk.
e. And mounting the partitions to a temporary directory, and respectively storing the resources to different directories according to the types of the resources (such as mirror image storage to images directory and network flow package storage to packets directory).
f. Generating the abstract information of all the resources and the unique serial number of the resource disk, and signing. And traversing the files in the resource directories, calculating the summary information of the single file by using an MD5, SHA1 or SHA256 algorithm for each file, and outputting the summary information together with the path of the file to a total summary file. And finally, signing the summary file through an RSA or DSA secret key to generate a signature file. The signature file, the digest file, and the resource are stored together in a resource disk.
2. A resource disk copy making module: and the system is responsible for copying the original resource disk into a plurality of identical copies according to the needs of users (besides the identical content, the unique number of the resource disk copy also needs to be identical to the number of the original resource disk). As shown in fig. 3, the resource disk copy is used for different project delivery on one hand and for post-assurance of each project on the other hand. The bottom layer of the resource disk copy making module is realized, and can call Linux file operation commands and also adopt special disk copying equipment.
3. Network shooting range resource disk monitoring module: the system is used for monitoring the state of the disk, sensing the change of the resource disk and informing the network target range resource management module in time.
a. When a disk is found to be inserted into the network backing plate server, an attempt is made to read the volume label of its first partition. If the tag is the desired predefined name (CRSRC as described above), a directory is created and the partition is mounted to the directory. Further, the abstract information of the resource disk and the unique serial number of the resource disk are read, and the signature is verified. If the signature is normal, the directory structure is scanned and the resource management module is notified to read the resource.
b. When the disk is found to be pulled out, the resource management module is informed to modify the resource state to be unavailable (i.e. to be deactivated).
c. A disk test procedure is run. This process periodically reads the resource disks. If the resource disk is found to be damaged, an alarm in the form of mail or a popup on the main interface is required, and then the resource management module is informed to disable the relevant resource (similar to pulling out the disk).
The resource disk monitoring module can detect the insertion and extraction of the disk by using a Linux udev frame and can also realize the detection by adopting an active round training mode.
4. The network target range resource management module: and the system is responsible for the operations of importing, modifying, deleting and the like of the resources. According to the storage mode of resources in the network shooting range platform, the method is divided into two types:
a. file type resources:
file type resources generally occupy more disk space, such as virtual node image files, software packages, network traffic packages, course videos, and the like. Such resources are not directly copied into the network shooting range platform but are registered by recording their paths or soft links. When the resource disk is pulled out or fails, only whether the file path corresponding to the resource is readable or not needs to be detected. If it is not readable, the path or soft link of these file resources is cleared (a single program can be designed to periodically scan all file-type resource directories, and for automatic clearing that is not readable, the relevant path or soft link can be cleared according to the unique number of the resource disk). After the resource disk copy is inserted again, forming keywords according to the unique number of the resource disk and the unique number or the unique name of the resource, re-registering the file type resource, covering the original invalid path or soft link, and enabling the network shooting range platform to access the resource on the resource disk copy instead.
b. Database type resource:
the database type generally needs to be imported into a database, but the data volume is small and the time consumption is low. Such as topological graphs, lesson exercises, and the like. When such resources are put in storage, the unique serial number of the resource disk needs to be recorded at the same time. If a resource needs to be deactivated, only the status field of the resource needs to be modified in the database. When a resource disk is unplugged or otherwise fails, the resource disk need not be read, although such resources are already fully present in the database. But it is likely that the file-type resource it depends on is not available and therefore can be considered to be deactivated altogether. The specific method is that all the resources imported from the resource disk in the database are required to be modified into the unavailable state according to the unique number of the resource disk. After the copy of the resource disk is inserted, under the condition that the file type resource is ensured to be completely imported, the unique number of the resource disk is read, and all resources related to the number in the database are modified into an available state in batches. Thus, the file resource path or soft link which has failed originally is updated to be the effective path or soft link, and the database type resource in the unavailable state is updated to be the available state. Therefore, the resources that become abnormal due to the original resource disk being pulled out or failing can be completely recovered.
Based on the same inventive concept, an embodiment of the present invention provides a server system of a network shooting range platform, including a memory, a processor, and a computer program stored on the memory and executable on the processor, where the computer program implements the following steps when being loaded into the processor: monitoring the disk state of the server; checking the disk characteristics when a disk is inserted, if the inserted disk is a resource disk, scanning the resources on the resource disk, warehousing or restarting the database type resources, and registering the file type resources; when the mounted resource disk is pulled out or fails, the database type resources are stopped, the registered file type resources are removed, after the resource disk is inserted into the server, the resources on the resource disk are scanned, and the resources are guided into the platform and started; the resource disk is a resource disk generated according to the resources selected by the user and the resources on which the selected resources depend, or a copy of the resource disk; for details, reference is made to the foregoing embodiments, which are not repeated herein.
