Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0025] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0026] Example 1

[0027] Figure 1 This is a flowchart of a cluster passwordless status inspection method provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where passwordless status checks are performed on cluster nodes. The method can be executed by a cluster passwordless status inspection device, which can be implemented in hardware and / or software and can be configured in the cluster management server. Figure 1 As shown, the method includes:

[0028] S110. Obtain the node description information of each node in the cluster to be detected through the target interface.

[0029] The target interface can refer to the interface used by the cluster management server to automatically query the node information database. This target interface can be defined as periodically and automatically retrieving node description information for passwordless status checks. The cluster to be checked can refer to the cluster that requires passwordless status maintenance. Node description information can refer to the node identity description information of each node in the cluster to be checked, which may include internet protocol addresses and hostnames.

[0030] This embodiment can automatically obtain the node identity description information of each node in the cluster to be detected through the interface of the management server, without manual intervention.

[0031] In one optional implementation, obtaining node description information of each node in the cluster to be detected through the target interface may include: querying a preset database through the target interface to obtain node description information of each node; wherein, the preset database is used to store cluster node data of the cluster to be detected.

[0032] In this embodiment, the cluster node data of the cluster to be detected can be automatically uploaded and stored in a preset database in advance. When passwordless status maintenance is required, the cluster management server can automatically query the node identity description information of all clusters to be detected and each node in each cluster from the preset database through the interface. This can avoid the need for manual intervention to input the node list in the case of large-scale cluster detection, thereby avoiding errors caused by human negligence and improving the accuracy of the obtained node list.

[0033] S120. Parse the node description information to obtain the cluster operation and maintenance file.

[0034] Among them, cluster operation and maintenance files can refer to files in a specific format required to implement cluster operation and maintenance.

[0035] In this embodiment, the obtained node description information can be parsed to obtain a file in the format required for cluster operation and maintenance.

[0036] In one optional implementation, parsing the node description information to obtain a cluster operation and maintenance file may include: calling a data parsing tool to parse the node description information to extract the Internet Protocol address and hostname; organizing the Internet Protocol address and hostname into a target standard format to obtain a cluster operation and maintenance file; the cluster operation and maintenance file includes the mapping relationship between the Internet Protocol address and the hostname.

[0037] Here, "data parsing tool" can refer to a JSON data parsing tool. "Target standard format" can refer to a mapping format between Internet Protocol addresses and hostnames that enables cluster operation and maintenance.

[0038] This embodiment can call a JSON data parsing tool to parse the node data obtained by the target interface to extract the Internet Protocol address and hostname in the node description information, and obtain the cluster operation and maintenance file based on the mapping relationship between the Internet Protocol address and the hostname.

[0039] In cluster operations and maintenance, the above parsing operations yield cluster operation and maintenance files to achieve automated management and configuration synchronization. By parsing cluster node information, standard-format cluster operation and maintenance files can be automatically generated, enabling automated configuration management: when cluster nodes change, scripts can automatically update the cluster operation and maintenance files, avoiding errors and inconsistencies from manual maintenance; standardizing operation and maintenance processes: generating uniform-format cluster operation and maintenance files facilitates reading and use by different operation and maintenance tools, improving operational efficiency; reducing human error: automated generation of cluster operation and maintenance files avoids potential issues such as incorrect Internet Protocol addresses or inconsistent hostnames caused by manual input; supporting dynamic expansion: when the cluster size changes, it can quickly adapt to new node configurations, ensuring that operation and maintenance tools can correctly identify all cluster nodes; this automation method is applicable to large-scale cluster environments, significantly improving operational efficiency and system reliability.

[0040] S130. Based on the cluster operation and maintenance documents, run the target detection script to log in to each node using the preset private key and detect the passwordless status of each node; wherein, the target detection script specifies that each node should use the preset public key to authenticate the preset private key first.

[0041] The target detection script can be used to detect the passwordless status of nodes. The cluster management server runs this target detection script and attempts to log in to each node using a preset private key, detecting the passwordless status of the node based on the authentication method specified in the target detection script.

[0042] In one optional implementation, based on the cluster operation and maintenance files, running a target detection script to log in to each node using a preset private key and detect the passwordless status of each node may include:

[0043] Based on the cluster operation and maintenance files, the current inspection node is determined sequentially from each node. The target detection script is run using the operation and maintenance tools to establish a secure connection with the current inspection node using a preset private key, enabling the current inspection node to check whether it has a passwordless configuration file. The passwordless configuration file contains a preset public key. If the current inspection node has a passwordless configuration file, the passwordless status check of the current inspection node is determined to be successful. If the current inspection node does not have a passwordless configuration file, the passwordless status check of the current inspection node is determined to be unsuccessful.

[0044] The currently checked node can refer to the object that the cluster management server is currently checking for passwordless login status. The passwordless configuration file can exist on the currently checked node, and the passwordless configuration file must contain the correct preset public key of the cluster management server in order to log in to the currently checked node without a password from the cluster management server.

[0045] In this embodiment, a current inspection node can be sequentially determined from each node of the cluster to be detected. The target detection script is run using an operation and maintenance tool to attempt to establish a secure connection with the current inspection node through a security protocol using a preset private key. If the current inspection node can successfully authenticate with the preset private key, it can be determined that the current inspection node has a passwordless configuration file, that is, the cluster management server has passed the passwordless status check of the current inspection node. If the current inspection node fails to authenticate with the preset private key, it can be determined that the current inspection node does not have a passwordless configuration file, that is, the cluster management server has failed the passwordless status check of the current inspection node.

[0046] The target detection script includes the following functional parameters: specifying the secure connection timeout, trusting the host, disabling host key checking, disabling password authentication, and prioritizing the use of a preset public key for authentication.

[0047] In this embodiment, the target detection script can specify the secure connection timeout between the cluster management server and the current inspection node, such as 5 seconds; it can specify the username for connection; it can specify to disable key checking of the current inspection node; it can specify to disable login password authentication on the cluster management server; and it can specify to prioritize the use of preset public key authentication between the cluster management server and the current inspection node.

[0048] Optionally, after detecting the passwordless status of each node, the process may further include: obtaining the passwordless status check results for each node; generating an inspection report based on the passwordless status check results, according to the cluster dimension of the cluster to be detected; wherein the inspection report includes the Internet Protocol address of the target node and the reason for the passwordless check failure, and the target node is the node that failed the passwordless check among all nodes.

[0049] In this embodiment, after each cluster node completes the passwordless status check, an inspection report can be automatically generated according to the dimension of the cluster to be tested. This inspection report can list the Internet Protocol addresses of the nodes in the cluster to be tested that failed the passwordless status check, as well as the reasons for the failure (such as the node not having the correct preset public key). The inspection reports of all the clusters to be tested managed by the cluster management server are summarized into a single file and placed in a designated path for operation and maintenance personnel to view and promptly re-password-free check. This embodiment's automated inspection and report generation can reduce the workload of administrators and lower labor costs.

[0050] Optionally, the cluster passwordless status inspection method in this embodiment may further include repairing the passwordless status of the target node according to a preset repair strategy; the preset repair strategy is to copy a preset public key to the target node; generating a prompt message based on the repair result and sending the prompt message to the operation and maintenance personnel.

[0051] This embodiment can also be designed with an automatic repair function (such as automatically copying a preset public key to the node that failed the passwordless check) to repair it for nodes identified in the previous step of the inspection. Successful or unsuccessful repair results can be automatically sent to maintenance personnel for record-keeping or manual intervention. This embodiment can promptly repair node passwordless configuration issues, ensure secure communication between cluster nodes, and reduce security risks.

[0052] Optionally, the cluster passwordless status inspection method in this embodiment can be configured with an inspection frequency (e.g., daily, weekly) to achieve periodic automated inspections, ensuring that the passwordless status of cluster nodes is always monitored and managed. This periodic automated inspection ensures that the cluster's passwordless status remains healthy, avoiding potential problems caused by untimely inspections.

[0053] The technical solution of this embodiment obtains node description information of each node in the cluster to be detected through the target interface; parses the node description information into a data format to obtain cluster operation and maintenance files; based on the cluster operation and maintenance files, runs a target detection script to log in to each node using a preset private key and detects the passwordless status of each node; the target detection script specifies that each node should use a preset public key to authenticate the preset private key. By adopting a technical means of automatically obtaining cluster operation and maintenance files by acquiring node description information and implementing passwordless status inspection based on the target detection script, this solution solves the problems that manual inspection methods are not only time-consuming and prone to errors, but also difficult to apply to large-scale clusters, thus improving the efficiency and accuracy of large-scale cluster management.
