[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] The technical solution provided by the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0040] Embodiment 1

[0041] Figure 1 FIG. 1 is a flow chart of a method for obtaining a license for a server cluster provided in Example 1 of the present application. Figure 1 As shown, the specific steps include:

[0042] Step S101, receiving and recording device fingerprint information reported by at least one server node;

[0043] Wherein, the server cluster is composed of a main server and at least one server node, and the method is executed by the main server in the server cluster;

[0044] The servers in a server cluster are connected together through a high-speed network and managed and coordinated using specific cluster software. When a client sends a request, the cluster software will distribute the request to different servers for processing based on certain algorithms. These algorithms may consider the server's load, performance indicators, or other factors to ensure that the request can be processed efficiently.

[0045] The main types of server clusters are: High-availability clusters, which aim to ensure service continuity. Even if one of the servers fails, other servers can immediately take over its work to ensure uninterrupted business. Redundant design is usually adopted, including redundant hardware components, network connections, and power supplies. Common high-availability cluster technologies include dual-machine hot standby and multi-machine redundancy. Load balancing clusters are mainly used to evenly distribute a large number of client requests to multiple servers to avoid excessive load on a single server, thereby improving the performance and throughput of the entire system. Load balancing can be implemented through hardware devices (such as load balancers) or software. Common load balancing algorithms include polling, weighted polling, and least connections. High-performance computing clusters focus on providing powerful computing power to handle complex scientific computing, engineering simulation, and data analysis tasks. Usually composed of a large number of computing nodes, which are connected by high-speed networks and work together using parallel computing technology. High-performance computing clusters require professional software and programming models to achieve efficient parallel computing.

[0046] The main server may be a server with the strongest computing power in the server cluster, for example, determined by automatic identification, obtained through election, or a pre-designated server.

[0047] Server nodes can be all servers in the server cluster except the main server, and can be called server nodes.

[0048] Among them, the main server needs to receive the device fingerprint information reported by the server node and record it. For example, the main server can send a broadcast message to inform other servers that they need to report device fingerprint information, and then receive the device fingerprint information reported by at least one server node within the agreed time period.

[0049] Among them, the device fingerprint information of the server is a set of attributes that can uniquely identify the hardware and software characteristics of the server. This information is of great significance for the management, security and performance optimization of the server. The composition of the device fingerprint information includes: Hardware information, such as server model: different server models have different performance and functional characteristics. CPU information: including model, number of cores, main frequency, etc. Memory capacity and type: the size and type of memory will affect the running speed and processing power of the server. Storage device information: hard disk capacity, type (such as mechanical hard disk or solid state hard disk), RAID configuration, etc. Network interface information: network card model, MAC address, etc. It also includes software information, such as operating system type and version: different operating systems have different security vulnerabilities and performance characteristics. Installed software list: various applications and services installed on the server. Software configuration information: such as database configuration, Web server configuration, etc. In addition, it can also include other information, such as the server serial number and asset number: used for asset registration and management. BIOS version: the version number of BIOS may affect the compatibility and stability of the server. The unique identifier of the device: such as UUID (Universally Unique Identifier).

[0050] The device fingerprint information of the server can be used for asset management, security management, and performance optimization. For example, it helps enterprises accurately identify and manage server assets, including the purchase, deployment, maintenance, and scrapping of equipment. It can quickly locate and resolve equipment failures and improve the availability and reliability of equipment. Or, it can be used for server authentication and access control. By verifying the device fingerprint information, it can ensure that only legitimate servers can access sensitive resources. It helps detect and prevent malware and network attacks. If the device fingerprint information is found to be inconsistent with expectations, it may mean that the server has been invaded or tampered with. Another example is that it can be used to understand the hardware and software configuration of the server, and performance optimization can be performed according to actual needs. For example, adjust memory allocation, optimize database configuration, etc. It can help administrators identify performance bottlenecks and take appropriate measures to improve the response speed and throughput of the server.

[0051] The method of obtaining the device fingerprint information of the server can be obtained by using operating system tools. For example, many operating systems provide command line tools or management interfaces to view the hardware and software information of the server. For example, in the Linux system, you can use commands such as lscpu, free-m, df-h, etc. to view the CPU, memory, and storage device information. Or use third-party software to obtain it. There are many third-party software that can be used to obtain the device fingerprint information of the server, such as hardware detection tools, system information tools, etc. These software usually provide more detailed and comprehensive information and can generate reports for administrators to refer to. Or obtain it through network scanning tools. Network scanning tools can obtain some device fingerprint information, such as operating system type, open ports, etc. by scanning the network ports and services of the server. However, this method may not be accurate enough and may be regarded as a security threat.

[0052] At the same time, the device fingerprint information of the server can also be updated regularly to ensure its accuracy and completeness.

[0053] Step S102, generating a total device fingerprint of the server cluster based on the recorded device fingerprint information;

[0054] The device fingerprint information may include the device fingerprint information of the main server, or may not include the device fingerprint information of the main server.

[0055] The method of generating the total device fingerprint can be implemented by using a specific algorithm, such as using a feature extraction method to extract key features from the collected device fingerprint information, because these features can represent the unique properties of the server cluster. For example, a specific hardware configuration combination, software version combination, and network architecture characteristics. Then encode and represent, and use a suitable encoding method to represent the extracted features as a total device fingerprint. Hash algorithms, unique identifier generation algorithms, etc. can be used to ensure that the generated fingerprint is unique and stable. Afterwards, the total device fingerprint can be stored in a centralized database or configuration file for subsequent management and query.

[0056] Step S103, sending or manually entering the total device fingerprint to the authentication and licensing server;

[0057] After generating the total device fingerprint, the main server may send or manually enter the total device fingerprint to the authentication and licensing server.

[0058] Among them, the authentication and licensing server is a type of server that plays a key role in the network environment. It is mainly responsible for authenticating the identity of users, devices or software and managing the corresponding license authorization. The authentication and licensing server can be used for identity authentication, authenticate users, and ensure that only legitimate users can access specific resources or services. This can be achieved in a variety of ways, such as usernames and passwords, digital certificates, biometrics, etc. For device authentication, ensure that the devices connected to the network are authorized to prevent illegal devices from accessing the network, thereby improving the security of the network. The authentication and licensing server can also be used for license management, responsible for managing the issuance, update and revocation of software licenses. For example, if an enterprise purchases a certain number of software licenses, the authentication and licensing server can ensure that only users within the scope of the license can use the software. Different types of licenses are classified and managed, such as permanent licenses, temporary licenses, concurrent licenses, etc., and are reasonably allocated according to actual needs. The working process of the authentication and licensing server includes: the user or device initiates a request. When the user tries to log in to the system or the device tries to connect to the network, it sends an authentication request to the authentication and licensing server. The request usually contains the user's identity information (such as username and password) or the device's feature information (such as MAC address, device serial number, etc.). During the authentication process, after receiving the request, the authentication license server verifies the request according to the pre-set authentication rules. This may involve operations such as querying the database, comparing passwords, and verifying digital certificates. If the authentication is successful, the server will return an authentication token or certificate, and the user or device can use this token or certificate to access protected resources within a certain period of time. Finally, the license is allocated. For software or services that require a license, the authentication license server will allocate the license based on the type and quantity of the license. If the use of the license reaches the limit, the server can reject the new request or prompt the user to purchase a new license.

[0059] Step S104, receiving a license issued by the authentication and licensing server;

[0060] After the authentication and licensing server authenticates and passes the total device fingerprint, a license may be issued to the main server or a license file may be generated for subsequent import. It is understandable that the license is issued for the entire server cluster.

[0061] Step S105, in response to the license verification request of the server node, returning the verification result of the server node.

[0062] Here, the query method can be implemented by pre-adopting an algorithm that is inverse to the algorithm for generating the total device fingerprint, so as to obtain the device fingerprint information of each server node received by the main server, so as to determine whether the device fingerprint information of the server node is included in the information. If it is included in the information, it means that the current server node has a license.

[0063] In the solution provided by the embodiment of the present application, the main server in the server cluster receives and records the device fingerprint information reported by the server node to generate the total device fingerprint of the server cluster, and then sends or manually enters the total device fingerprint to the authentication and licensing server to obtain a license. When the server node needs to be verified, it can send a license verification request to the main server. If its own device fingerprint information is in the total device fingerprint, it is determined that the server node has passed the verification. By implementing this solution, the efficiency of issuing licenses to the server cluster can be improved.

[0064] Embodiment 2

[0065] Figure 2 This is a flow chart of the license acquisition method for a server cluster provided in Example 2 of the present application. The specific optimization is: generating a total device fingerprint of the server cluster based on the recorded device fingerprint information, including: constructing a fingerprint list based on the recorded device fingerprint information; generating a total device fingerprint of the server cluster based on the recorded device fingerprint information, and associating the fingerprint list with the total device fingerprint.

[0066] like Figure 2 As shown, the specific steps include:

[0067] Step S201, receiving and recording device fingerprint information reported by at least one server node;

[0068] Step S202, constructing a fingerprint list with the recorded device fingerprint information;

[0069] The received device fingerprint information of each server node may be used to construct a fingerprint list. For example, the fingerprint list may include two columns, one column for the ID of the server node and the other column for the device fingerprint information of the server node.

[0070] Step S203, generating a total device fingerprint of the server cluster based on the recorded device fingerprint information, and associating the fingerprint list with the total device fingerprint;

[0071] After the total device fingerprint is generated, an association relationship may be established between the fingerprint list and the total device fingerprint.

[0072] Figure 3 FIG. 1 is a flow chart of the license acquisition process of the server cluster provided in the second embodiment of the present application. Figure 3 As shown, the scheme mainly includes the following steps:

[0073] Each server node reports the device fingerprint to the central server;

[0074] The central server records the collected device fingerprints;

[0075] The central server generates a total device fingerprint, i.e., a cluster device fingerprint, based on the collected device fingerprints;

[0076] Issue licenses for cluster device fingerprints;

[0077] Each server node can query the central server to see if it has been authorized.

[0078] This solution can manage multiple server authorizations through one device fingerprint, saving the time of obtaining device fingerprints and issuing licenses for multiple devices. The more servers there are, the more time is saved.

[0079] Step S204, sending or manually entering the total device fingerprint to the authentication and licensing server;

[0080] Step S205, receiving a license issued by the authentication and licensing server;

[0081] Step S206: In response to the license verification request of the server node, the verification result of the server node is returned.

[0082] For example, the total device fingerprint is sent to a server node, so that the server node can query whether its own device fingerprint information is in the total device fingerprint. If it is in the total device fingerprint, it is determined that the server node has passed the verification.

[0083] Based on the above embodiments, this embodiment provides a method of constructing a fingerprint list and associating the fingerprint list with the total device fingerprint, which can facilitate subsequent query of each server node whether it has a license and whether it can pass the license verification.

[0084] In this solution, optionally, in response to a license verification request from a server node, the total device fingerprint is sent to the server node, so that the server node can query whether its own device fingerprint information is in the total device fingerprint, and if it is in the total device fingerprint, it is determined that the server node has passed the verification, including:

[0085] In response to the license verification request of the server node, the total device fingerprint and the fingerprint list associated with the total device fingerprint are sent to the server node, so that the server node can query whether its own device fingerprint information is in the fingerprint list. If it is in the fingerprint list, it is determined that the server node has passed the verification.

[0086] This solution can send the fingerprint list to the server node, so that the server node can query whether its own device fingerprint information is in the fingerprint list. Therefore, in the process of verifying the license at the server node, there is no need to use any algorithm to process the total device fingerprint, thereby improving the verification efficiency and simplifying the verification operation.

[0087] In this solution, optionally, after receiving the license issued by the authentication and licensing server, the method further includes:

[0088] In response to the license verification request of the server node, a fingerprint list associated with the total device fingerprint is queried, and if the device fingerprint information of the server node is in the fingerprint list, verification passing information is sent to the server node.

[0089] In this solution, a main server can verify whether a server node has a license by searching through a fingerprint list stored in the main server, obtaining a verification result, and feeding the verification result back to the server node. Thus, the server node can obtain the verification result after issuing a license verification request without transmitting a large amount of data, thereby simplifying the interaction process.

[0092] Step S401, reporting device fingerprint information of the server node to the main server for recording by the main server, and generating a total device fingerprint of the server cluster based on the device fingerprint information, so as to send or manually enter the total device fingerprint to the authentication and licensing server, and receive a license issued by the authentication and licensing server;

[0093] Step S402, sending a license verification request to the main server, and receiving the total device fingerprint sent by the main server;

[0094] Step S403, query whether the fingerprint information of the own device is in the total device fingerprint, and if so, determine that the verification is passed.

[0095] In this embodiment, optionally, sending a license verification request to a main server and receiving a total device fingerprint sent by the main server include:

[0096] Sending a license verification request to the main server, receiving the total device fingerprint and the fingerprint list associated with the total device fingerprint sent by the main server;

[0097] The method further comprises:

[0098] Check whether the fingerprint information of the own device is in the fingerprint list associated with the total device fingerprint. If it is in the fingerprint list, it is determined that the verification is passed.
