[0045] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0046] Referring to Figure 1 , a server node operation method provided in an embodiment of the present application, as shown in Figure 1 , applied to an automation tool, the automation tool is in communication connection with a message robot and a server node, and the method can specifically include the following steps:

[0047] Step 101, receiving an operation instruction sent by the message robot; the operation instruction at least includes a network address of a server node to be operated and an operation type.

[0048] Exemplarily, referring to Figure 2 , a schematic diagram of an application environment provided in an embodiment of the present application, including 201 automation tool, message robot 202 and server node 203, the automation tool is in communication connection with the message robot, so that the automation tool and the message robot can receive and send messages to each other, the automation tool is in communication connection with the server node (host / node), so that the automation tool can send a command or a message to the server node, and the server node can process based on the received command or message, and feed back the corresponding result to the automation tool according to the processing result of the command or message. Wherein, the server node can be a CDN node in a content distribution network (CDN), of course, it can also be a node in other server system, the embodiment of the present application does not need to be limited thereto.

[0049] In a specific embodiment, the automation tool (automation operation and maintenance tool) can be ansible, which is used for configuration management, application deployment, task execution and the like, the automation tool can send an operation instruction to the server node, so that the server node processes the operation instruction, and feeds back the execution result after processing the operation instruction, of course, the automation tool can also be other tools capable of realizing operation instruction processing, the embodiment of the present application does not need to be limited thereto.

[0050] The message robot is a robot tool in an enterprise-level communication tool. The enterprise-level communication integrates functions such as work communication and collaborative office. Based on the message robot in the enterprise-level communication, an operator can quickly generate an operation instruction based on a template provided by the message robot and send the operation instruction to an automation tool, and receive an execution result of the operation instruction forwarded by the automation tool. The server node can be a server node (CDN node) in a CDN (content distribution network), and is usually multiple, and can also be one. The server node is responsible for content distribution, and needs to be isolated when a fault occurs. The server node isolation refers to isolating the faulty server node from other server nodes through physical or logical means, preventing the problem of one server node from spreading to other server nodes, reducing potential security risks and fault impacts, and improving the stability and security of the overall content distribution network.

[0051] The automation tool is connected with an operation and maintenance system (an internal operation and maintenance platform or a process management system of the server node, and the operator can operate the server node through the operation and maintenance system). The operation and maintenance system is responsible for process control and permission management. The operation and maintenance system can receive the operation instruction sent by the message robot, and perform permission verification and processing on the received operation instruction, and send the operation instruction to the automation tool after the permission verification is successful and the processing is completed. The automation tool processes the server node according to the operation instruction.

[0052] In the embodiment of the application, the automation tool can receive the operation instruction sent by the operator through the message robot. The operation instruction at least includes a network address of a server node to be operated and an operation type. In a specific example, the automation tool receives an operation instruction containing an IP address (network address) of a CDN node to be operated, a device name, an operation type (isolation type / recovery type / shutdown type), a name of a message robot authorized person, a message robot ID (identity), and a name of a message robot user through the message robot. The message robot realizes the reception and transmission of cross-platform operation instructions, simplifies the operation process of the operator, improves the flexibility and convenience of the operation, and further improves the processing efficiency of the server node fault.

[0053] Reference Figure 3a A user interface schematic diagram provided in the embodiment of the application is provided. When the operator finds the server node with a fault, the operator can call out the message robot in the enterprise-level communication, and then the message robot can provide an input interface for the user. Based on the input interface, the operator can select the input template provided by the message robot to generate the operation instruction for the server node. For details, refer to Figure 3bBased on the input template, the operator can input the relevant information of the server node, such as the operation type, city, IP address, etc. After the operator completes the input based on the input template, the operation instruction can be generated by clicking the 'execute' button, and the operation instruction is submitted to the automation tool for further processing.

[0054] The embodiment of the application sends operation instructions and receives corresponding feedback and other information such as operation instructions through the message robot, and uses the automation tool ansible to automatically execute the operation instructions, thereby realizing the operation such as isolation / restoration / shutdown of the server node. Thus, the mobile phone and other portable terminals realize one-key isolation / restoration / shutdown of a single CDN node through the message robot, and realize the rapid management of the CDN node (server node) on the mobile device. The fault processing time of the CDN node is significantly shortened from the original 6-10 minutes to almost instant response, the fault processing efficiency is improved, the user perception is improved, and the operation personnel does not need to operate in a specific intranet environment, which greatly facilitates the operation execution.

[0055] It should be noted that the embodiments of the application may involve the use of user data. In actual application, user-specific personal data can be used in the schemes described herein within the scope allowed by applicable laws and regulations, for example, with the explicit consent of the user, with the actual notification to the user, etc.

[0056] Step 102, sending a network test command to the server node according to the network address.

[0057] Step 103, receiving the network test result sent by the server node for the network test command.

[0058] In a specific example, the network test command can be a ping command. Specifically, the ping command can be used to test the availability and delay of the network connection of the server node. Of course, the network test command can also be other commands that can be used to test the network state of the server node, and the embodiments of the application do not need to be limited thereto.

[0059] In the embodiment of the present application, the network test command is executed on the corresponding host (server node) according to the IP address of the server node input by the operator in the operation instruction, the server node executes the network test command correspondingly after receiving the network test command, the network test result is generated based on the execution result of the network test command, and is sent to the automation tool. The network test result can at least include that the server node is in a reachable state or that the server node is in an unreachable state. When the server node is in the reachable state, it means that the server node is accessible, that is, other server nodes or automation tools can be connected to the server node through the network. When the server node is in the unreachable state, it means that the server node is inaccessible, that is, other server nodes or automation tools cannot be connected to the server node through the network.

[0060] Step 104, determining the feasibility of the server node executing the operation instruction according to the network test result and the operation type.

[0061] Step 105, processing the operation instruction according to the feasibility.

[0062] In a specific implementation, the server node cannot normally execute part of the operation instruction due to various reasons. If the operation instruction received by the server node may not be normally executed, the repair speed of the server node fault is reduced.

[0063] In the embodiment of the present application, the automation tool can determine the feasibility of the server node executing the operation instruction according to the operation type in the operation instruction after obtaining the network test result of the server node, and then process the operation instruction according to the feasibility. In this way, the operation instruction can be sent to the server node for processing when the feasibility is feasible, so that the server node can normally receive and process the operation instruction, and the fault processing efficiency of the server node is ensured. In addition, the operation instruction can also be sent to the server node for processing when the feasibility is infeasible. Since the server node cannot receive the operation instruction or cannot execute the operation instruction, the fault processing efficiency of the server node is reduced, and unnecessary network resources are wasted. For example, the automation tool judges the server node state by pinging the dispatching network element RRS to obtain the network test result before executing the isolation operation instruction, and ensures the effectiveness of the operation.

[0064] In the server node operation described above, the automation tool receives an operation instruction sent by the message robot, the operation instruction at least including an operation type of a server node to be operated, sends a network test command to the server node according to a network address to obtain a network test result of the server node, determines the feasibility of the server node executing the operation instruction according to the network test result and the operation type, and then processes the operation instruction according to the feasibility. The embodiment of the present application can remotely control the server node through the automation tool, without the need to operate the server node in a specific intranet environment, thereby improving the processing efficiency of the server node fault, reducing the fault recovery time of the server node, and further improving the user experience of the server node. In addition, the automation tool can predict the feasibility of the server node executing the operation instruction according to the network test result and the operation type, and process the operation instruction according to the predicted feasibility. In this way, the operation instruction is sent to the server node only when the feasibility of the server node executing the operation instruction is feasible, thereby enhancing the security and reliability of the server node operating based on the operation instruction.

[0065] In an embodiment of the present application, determining the feasibility of the service node executing the operation instruction according to the network test result and the operation type comprises:

[0066] When the network test result indicates that the server node is in a reachable state and the operation type is an isolation type, it is determined that the feasibility of the service node executing the operation instruction is feasible.

[0067] When the network test result indicates that the server node is in an unreachable state and the operation type is an isolation type, it is determined that the feasibility of the service node executing the operation instruction is infeasible.

[0068] In the embodiment of the present application, if the network test result indicates that the server node is in a reachable state and the operation type is an isolation type, it is determined that the feasibility of the service node executing the operation instruction is feasible, and a message is sent to the operator through the message robot to inform the operator that the operation of the operation instruction of the isolation type is feasible. On the contrary, if the network test result indicates that the server node is in an unreachable state and the operation type is an isolation type, it is determined that the feasibility of the service node executing the operation instruction is infeasible, and a message is sent to the operator through the message robot to inform the operator that the operation of the operation instruction of the isolation type is infeasible, and the process ends.

[0069] In an embodiment of the present application, determining the feasibility of the service node executing the operation instruction according to the network test result and the operation type comprises:

[0070] When the network test result indicates that the server node is in an unreachable state and the operation type is a recovery type, it is determined that the service node is feasible to execute the operation instruction.

[0071] When the network test result indicates that the server node is in a reachable state and the operation type is a recovery type, it is determined that the service node is not feasible to execute the operation instruction.

[0072] In an embodiment of the present application, if the network test result indicates that the server node is in an unreachable state and the operation type is a recovery type, it is determined that the service node is feasible to execute the operation instruction, and a message robot is used to send a message to an operator to inform that the operation of the operation instruction of the recovery type is feasible; otherwise, if the network test result indicates that the server node is in a reachable state and the operation type is a recovery type, it is determined that the service node is not feasible to execute the operation instruction, and the message robot is used to send a message to the operator to inform that the operation of the operation instruction of the recovery type is not feasible, and the flow ends.

[0073] In an embodiment of the present application, the determination of the feasibility of the service node to execute the operation instruction according to the network test result and the operation type comprises:

[0074] When the network test result indicates that the server node is in a reachable state and the operation type is a shutdown type, it is determined that the service node is feasible to execute the operation instruction.

[0075] When the network test result indicates that the server node is in an unreachable state and the operation type is a shutdown type, it is determined that the service node is not feasible to execute the operation instruction.

[0076] In an embodiment of the present application, if the network test result indicates that the server node is in a reachable state and the operation type is a shutdown type, it is determined that the service node is feasible to execute the operation instruction, and a message robot is used to send a message to an operator to inform that the operation of the operation instruction of the shutdown type is feasible; otherwise, if the network test result indicates that the server node is in an unreachable state and the operation type is a shutdown type, it is determined that the service node is not feasible to execute the operation instruction, and the message robot is used to send a message to the operator to inform that the operation of the operation instruction of the shutdown type is not feasible, and the flow ends.

[0077] In the above embodiment, the automation tool sets an automation judgment mechanism, and based on the automation judgment mechanism, the server node can be judged whether to execute the operation instruction according to the network test result of the server node and the operation type of the operation instruction. The automation judgment mechanism ensures that the corresponding operation instruction is executed only when the network is reachable and the operation type is allowed, especially the operation instruction of the isolation type, thereby enhancing the safety and reliability of the operation.

[0078] In an embodiment of the present application, processing the operation instruction according to the feasibility can include:

[0079] When the feasibility of the service node executing the operation instruction is feasible, the operation instruction is sent to the server node according to the network address; wherein the server node is used to execute the operation instruction.

[0080] When the feasibility of the service node executing the operation instruction is infeasible, the message robot is sent prompt information that the server node is infeasible to execute the operation instruction.

[0081] In the embodiment of the present application, when the automation tool determines that the feasibility of the service node executing the operation instruction is feasible, the operation instruction can be sent to the corresponding server node according to the network address in the operation instruction. The server node executes the operation instruction after receiving the operation instruction and obtains the execution result. When the automation tool determines that the feasibility of the service node executing the operation instruction is infeasible, the message robot is sent prompt information that the server node is infeasible to execute the operation instruction, reminding the operator to perform the next step.

[0082] In an embodiment of the present application, sending the operation instruction to the server node according to the network address can include

[0083] The message robot is sent the approval information for the operation instruction.

[0084] When the approval result of agreeing to execute the operation instruction for the approval information is received, the operation instruction is sent to the server node according to the network address.

[0085] In the embodiment of the present application, if the feasibility of the server node executing the operation instruction is feasible according to the network test result and the isolation type, the operation instruction can be sent to the server node for processing, so that the server node can normally receive and process the operation instruction, and the fault processing efficiency of the server node is ensured. In some optional embodiments, in order to further ensure the safety of the server node, if the feasibility of the server node executing the operation instruction is feasible according to the network test result and the isolation type, an approval link can be added, and whether the operation instruction can be sent to the server node for processing is determined according to the approval result of the approval link. When the approval result of the approval information is received, the operation instruction is sent to the server node according to the network address, so that the server node executes the operation instruction.

[0086] Exemplarily, referring to Figure 3c If the network test result of the server node is reachable state by using the ping command, and the operation type is the isolation type, it is determined that the feasibility of the operation instruction is feasible, and the prompt information that the operation instruction is feasible is displayed on the message robot. At this time, the approval link can be entered. When the approval link is entered, the approval information of the operation instruction is sent to other message robots (which can include the message robot sending the operation instruction). If the operator agrees to execute the operation instruction, the approval result of the operation instruction can be received. When the approval result of the operation instruction is received, the operation instruction is sent to the server node according to the network address, so that the server node executes the operation instruction. After the message robot initiates the operation instruction, the process in the embodiment of the present application includes the necessary approval step, which ensures the correctness and legality of the operation based on the operation instruction, reduces the network and skill requirements of the maintenance personnel in the single server node fault scenario, and ensures the compliance and safety of the operation.

[0087] In the embodiment of the present application, after the operation instruction is approved, the automation tool ansible can execute the isolation command and other operation instructions on the remote host (server node) using the ansible interface, simulate denial of service through iptables, or restore service, or shut down the function by stopping the server node process. In the embodiment of the present application, the server node is isolated by using iptables instead of stopping the process. Compared with stopping the process, the impact on users is smaller when simulating denial of service using iptables, because the iptables rule is temporary and will not be permanently saved in the system. When the system is restarted, the iptables rule will be automatically cleared when the HMS device is restarted, and the system will return to the normal state. That is, even if the iptables rule is applied incorrectly, the system will return to normal after restarting and will not affect business continuity. This minimizes the impact on user services while maintaining the efficiency of the operation. In addition, the addition and deletion of iptables rules is very fast and can be completed in a few seconds. Therefore, when the server node needs to be isolated or restored, it can respond quickly and reduce the impact on users.

[0088] In an embodiment of the present application, when the service node can execute the operation instruction, after the operation instruction is sent to the server node according to the network address, the method further comprises:

[0089] receiving the execution result of the operation instruction sent by the server node;

[0090] sending the execution result of the operation instruction to the message robot.

[0091] In the embodiment of the present application, after the server node executes the operation instruction, the automation tool can receive the execution result of the operation instruction sent by the server node. At this time, the automation tool can send the execution result of the operation instruction, the server node that executes, the IP address, the applicant and other information to the message robot, so that the relevant personnel can know the current state of the server node. For details, please refer to Figure 3d

[0092] By sending the execution result of the operation instruction of the server node to the fault handling group or other related groups through the message robot, it is ensured that the operator can know the operation state in time. Through the result feedback mechanism, the operation is transparent, which is convenient for team cooperation and fault tracking.

[0093] In order for those skilled in the art to better understand the embodiments of the present application, the following will be described with specific examples.

[0094] For example, assume that the operation instruction received by the automation tool ansible is to isolate the CDN node. The specific steps are as follows:​

[0095] (1) Receive operation instructions: The operator issues an isolation instruction through the message robot, and the isolation instruction contains the IP address, device name and other related information of the CDN node.

[0096] (2) Determine the feasibility: The automation tool ansible executes the ping command of the RRS (server node) of the dispatching network element according to the IP address of the CDN node, checks whether the CDN node is reachable. If the CDN node is reachable, the message robot sends a message to confirm that the isolation operation can be performed; if the CDN node is not reachable, a message is sent to prompt that the operation is not feasible.

[0097] (3) Operation audit: If it is confirmed that the CDN node can be isolated, the message robot sends a message prompting that the operation needs to be audited, and the pre-determined operation audit group approves the operation. If the approval is passed, the operation execution link is entered, and if it is not passed, the process is ended.

[0098] (4) Perform isolation operation: The automation tool ansible sends an iptables command to the target CDN node to simulate denial of service and realize node isolation. After the automation tool ansible executes the command, the command execution result is checked, and the operation result is sent to the fault handling group through the message robot.

[0099] (5) Result feedback: The execution result is fed back to the fault handling group in real time. In addition to the execution result, detailed information such as the success or failure of isolation can also be included.

[0100] Through the above process, the CDN node is quickly isolated, the fault recovery time is reduced, the technical dependence on the operation and maintenance personnel is reduced, and the operation and maintenance efficiency is improved. In addition, the approval link is added, which reduces the network and skill requirements of the maintenance personnel in the single CDN node fault scenario, greatly reduces the fault recovery time, and has good popularization value.

[0101] In view of the high-definition business customer service pressure, the perception requirement is high, and the operation and maintenance characteristics are put forward. The requirement of fast isolation of fault equipment for high-definition maintenance support. Originally, the CDN node needs to be logged in to the network management WEB to stop the heartbeat, and the operation needs 6-10 minutes, which is too long, and needs a specific internal network environment. From the perspective of improving fault handling efficiency and user perception, the embodiment of the application proposes to realize the portable terminal such as mobile phone based on the automation tool ansible automation tool, and uses the message robot to isolate / recover / stop the server node in the single CDN.

[0102] The embodiments of the present application can be applied to high-definition service operation and maintenance, aiming to use message robots on mobile terminals and other portable terminals to one-key isolate, recover or shut down individual CDN nodes (server nodes) to quickly respond to failures and ensure user experience. In specific implementation, high-definition service refers to a service or a service that provides high-quality, high-resolution content, which usually includes video, audio, image, etc., aiming to provide users with clearer and more delicate visual and auditory experience. Key devices and technologies involved in high-definition service operation and maintenance can include:

[0103] CDN node (server node): responsible for content distribution and needs to be isolated when a failure occurs. Message robot: an enterprise-level communication tool for sending operation instructions and receiving result feedback. Ansible: an automation tool for executing remote operation commands (including operation instructions). Operation and maintenance system: an internal operation and maintenance platform or process management system responsible for process control and permission management.

[0104] The communication connection relationship between each device is as follows: the user initiates the operation instruction of isolation / recovery / shutdown through the message robot; the operation and maintenance system performs permission verification and processing on the received operation instruction command; the automation tool ansible executes the operation instruction according to the parameters transmitted by the operation and maintenance system to isolate / recover / shutdown the corresponding CDN node; the automation tool ansible feeds back the execution result to the user through the message robot.

[0105] In an optional embodiment: during the high-definition service operation and maintenance, a certain CDN node fails and needs to be quickly isolated to prevent affecting user experience. The specific steps can include:

[0106] 1. The user sends an operation instruction to isolate the failed CDN node through the message robot.

[0107] 2. The operation instruction can at least include the CDN node IP address, device name, operation type (isolation / recovery / shutdown), message robot authorized person name, message robot ID, and message robot user name to be operated.

[0108] 3. The automation tool ansible issues a ping measurement RRS command to the corresponding host according to the input CDN node IP address, parses the ping measurement result to obtain the network test result, and judges whether to perform the subsequent process in combination with the input operation type.

[0109] 4.
