Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a method, apparatus, device, and storage medium for switching between a primary and a secondary server group. Background Art

[0002] Currently, aviation ground service systems typically receive downlink data from aircraft through various data link methods, such as ADS-B (Automatic Dependent Surveillance-Broadcast), Beidou short messages, and KA-band satellite communications, and implement functions such as reorganization, packaging, parsing, processing, user interaction, and storage of downlink data. Users can use a browser (such as a web browser) to access the downlink data stored or processed by the aviation ground service system.

[0003] However, in many application scenarios, such as the scenario where dual Beidou command aircraft receive airborne original messages, the aviation ground service system adopts a master-slave redundant design and needs to meet the requirements of master-slave switching, such as Figure 1 As shown, it includes a primary server group and a backup server group, and each server group can contain several servers, and each server can run several application software processes. The two server groups can serve as the primary and backup for each other. Figure 1 Mainstream approaches for master-slave switching between two server groups in a cluster include: a switchover solution based on microservice clusters (such as Spring Cloud) and a master-slave switching solution based on Zookeeper (an open source distributed coordination framework). The microservice cluster-based switchover solution develops a single process as a small service and deploys multiple identical processes in a distributed manner using cluster technology. Each process runs independently and uses lightweight mechanisms, such as communicating through an API (Application Programming Interface) of an HTTP (Hypertext Transfer Protocol) resource, so that the corresponding process can be called through the API for data processing. However, this approach requires strict adherence to the microservice framework and the use of the technical support provided by the microservice framework when developing each application software (program), and cannot achieve complete decoupling from the microservice framework. Furthermore, this approach cannot meet the requirement of the master-slave switching solution that only one server group can run simultaneously in the master and standby server groups, and requires the addition of additional logical functions. The Zookeeper-based master-slave switching solution also requires the use of the API and technical support provided by Zookeeper when developing the process. The master-slave switching logic must be implemented within the process, and the process cannot be fully decoupled from the Zookeeper framework.

[0004] In summary, how to implement active / standby switching of a server group is a problem that still needs to be further solved in this field. Summary of the Invention

[0042] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0043] The present invention discloses a method for switching between a primary and a secondary server group, which is applied to a primary and a secondary server group switching system including a first server group and a second server group. The first server group and the second server group each include multiple servers, and each of the servers is integrated with a process control component. Figure 2 As shown, the method includes:

[0044] Step S11: Monitor and receive the heartbeat messages sent by the process control components in each server in the first server group through the first group of management components integrated in any server located in the first server group, and obtain a process heartbeat message; wherein, the process heartbeat message includes the identifier corresponding to each process control component in the first server group and the process status information of all controlled processes.

[0045] It should be pointed out that the active-standby switching solution for server groups proposed in this application is applied to an active-standby switching system comprising two server groups (respectively, a first server group and a second server group), wherein the first server group and the second server group each contain multiple servers, and each of the servers is pre-integrated with a process control (Process Control) component for controlling all processes in the current server. The processes in the server include but are not limited to office software, such as processes in Word, PPT and other software, as well as controlled processes in aviation ground service station software. It should be pointed out that the active-standby switching system can be implemented through different operating systems and programming languages, such as using the Linux operating system and C++ language for development and implementation, and can be further reconstructed into a Windows application.

[0046] Also, see Figure 3 As shown, a management (Group Manager) component is pre-integrated in any server of the first server group and the second server group, namely the first group management component and the second group management component. In the initial state, the first server group is used as the main server group and the second server group is used as the backup server group by default, and only one server group (i.e., the first server group) is working. It should be pointed out that there is one and only one group management component in each server group. Moreover, each component can communicate with each other through a pre-set communication method to realize the sharing of message information. The communication method includes but is not limited to UDP (User Datagram Protocol) multicast, UDP unicast, TCP (Transmission Control Protocol) protocol, HTTP protocol, RS485 (a serial communication standard) protocol, etc.

[0047] In this embodiment, the first group management component integrated in any server located in the first server group can monitor and receive the heartbeat messages sent by the process control components in each server in the current first server group in real time, and obtain corresponding process heartbeat messages; wherein, the process heartbeat message specifically includes the identifier corresponding to each process control component in the first server group (such as Process Control_1-1, Process Control_1-2, ProcessControl_1-3, etc., respectively indicating the process control component in the server in the first server group) and the process status information of all controlled processes (such as status0 indicates that all processes have not been started; status1 indicates that some processes have been started; status2 indicates that all processes have been started).

[0048] In a specific embodiment, the first group management component integrated in any server of the first server group monitors and receives the heartbeat message sent by the process control component in each server in the first server group to obtain the process heartbeat message, which may specifically include: monitoring and receiving the heartbeat message sent by the process control component in each server in the first server group through UDP multicast and according to a preset sending period by the first group management component integrated in any server of the first server group to obtain the process heartbeat message. For details, see Figure 3 As shown, the process control component in each server in the first server group sends heartbeat messages to the UDP multicast according to a preset sending period (such as every 2 seconds), and the first group management component integrated in any server of the first server group obtains the process heartbeat messages sent by each process control component in the group from the UDP multicast in each preset receiving period (such as every 2 seconds).

[0049] It should be pointed out that, before obtaining the process heartbeat message, the first group management component integrated in any server of the first server group monitors and receives the heartbeat message sent by the process control component in each server in the current first server group, specifically also includes: monitoring and receiving the heartbeat message sent by the second group management component integrated in any server of the second server group through the first group management component, to obtain the group management heartbeat message; the group management heartbeat message includes the running status information and the corresponding master-slave priority of the second group management component; if the running status information in the group management heartbeat message is in the closed state, and the master-slave priority is the backup server group, the first server group is determined to be the master server group. In this embodiment, when the first server group is the master server group in the default initial state, it is necessary to close all processes in the second server group through the first group management component in the first server group, so as to ensure that only one server group is running and the other is in use. Specifically, the heartbeat message sent by the second group management component integrated in any server located in the second server group is first monitored and received by the first group management component, and the group management heartbeat message corresponding to the second group management component containing the operating status information of the second group management component and the corresponding master-slave priority is obtained. If the operating status information in the above group management heartbeat message (such as status0 indicating that the component is being initialized; status1 indicating that the component is in the shutdown state; status2 indicating that the component is in the startup state; status3 indicating that the component is in an abnormal state) indicates that the operating status of the second group management component is the shutdown state (i.e., status1), and the corresponding master-slave priority is the backup server group, then the first server group can be determined as the master server group. It should be pointed out that the monitoring of the status information of other components by each component can be achieved through a state machine.

[0050] Step S12: detecting whether all controlled processes in the servers of the first server group have been started according to the process status information in the process heartbeat message.

[0051] In this embodiment, after monitoring and receiving the process heartbeat message sent by the process control component in each server in the current first server group, further, based on the process status information in the above process heartbeat message, it can be detected whether all controlled processes located in each server in the above first server group have been started.

[0052] Step S13: If all controlled processes in each server in the first server group are not started, a control message for shutting down the process is sent to the process control component in each server in the first server group to shut down all controlled processes in each server in the first server group.

[0053] In this embodiment, if all controlled processes in the servers located in the above-mentioned first server group are not started, that is, there are unstarted processes in the first server group, a control message for closing all processes in the current server is sent to the process control component in each server located in the above-mentioned first server group. After each server in the first server group receives the above-mentioned control message, it closes all processes controlled by itself.

[0054] Step S14: Send the heartbeat information of the current first group management component to the second group management component, so as to switch the second server group to the main server group through the second group management component, and start all controlled processes in each server in the second server group; the second group management component is a group management component integrated in any server located in the second server group.

[0055] In this embodiment, after closing all controlled processes in each server in the first server group through the first group management component, the first group management component can further send the heartbeat information of the current first group management component to the second group management component integrated in any server located in the above-mentioned second server group; when the second group management component receives the heartbeat information sent by the first group management component, it switches the current second server group to the main server group, and starts all controlled processes in each server in the current second server group, that is, converts the second server group from a backup server group to a main server group.

[0056] In this embodiment, the server group active / standby switching method may further include: determining all controlled processes of each server in the first server group to obtain a first controlled process, obtaining process information of each first controlled process to obtain first process information, and then saving all first process information to a first configuration file; the first configuration file is located on the server where the first group management component is located; determining all controlled processes of each server in the second server group to obtain a second controlled process, obtaining process information of each second controlled process to obtain second process information, and then saving all second process information to a second configuration file; the second configuration file is located on the server where the second group management component is located. All controlled processes of each server in the first server group may be determined in advance to obtain the corresponding first controlled process, then obtaining process information of each first controlled process to obtain first process information, and then saving all first process information to a first configuration file located on the server where the first group management component is located, so that the information in the configuration file is automatically loaded when the server is powered on, thereby starting each controlled process. Similarly, all controlled processes of each server in the second server group are determined respectively to obtain the corresponding second controlled processes, and then the process information of each second controlled process is obtained to obtain the second process information, and then all the first process information is saved to the second configuration file of the server where the second group management component is located, so that the information in the configuration file can be automatically loaded when the server is started, thereby starting each controlled process.

[0057] Among them, the first process information and the second process information both include a process name (such as ID, PID, etc.), a process start instruction, a process close instruction, a process close instruction and a process monitoring instruction; the process start instruction can specifically be a Linux shell instruction and is located in a sh file, the process close instruction can use the killall instruction or the kill instruction, and the process monitoring instruction can use the ps instruction (a Linux system command).

[0058] Accordingly, starting all controlled processes in each server in the second server group may specifically include starting all controlled processes in each server in the second server group using the process start instruction in the second configuration file. That is, when starting all controlled processes in each server in the second server group, the process start instruction pre-stored in the second configuration file may be directly called to start the corresponding controlled processes.

[0059] In a specific embodiment, it may also include: monitoring the heartbeat information of the first group management component through the process control component in each server in the first server group respectively, and if the heartbeat information sent by the first group management component is not received within a preset time period, then shutting down all controlled processes in the corresponding server; the controlled process is a process in the aviation ground service station software. In this embodiment, the heartbeat information of the first group management component can be monitored by the process control component in each server in the first server group. If the heartbeat information sent by the first group management component is not received within a preset time period, it indicates that the current server group is a backup server group, and it is necessary to shut down all controlled processes in the corresponding server; wherein, the controlled process can specifically be a process in the aviation ground service station software, such as the reorganization, packaging, parsing, processing, user interaction, storage and other processes of downlink data.

[0060] It can be seen that the embodiment of the present application is applied to a master-slave switching system including a first server group and a second server group, wherein the first server group and the second server group each include multiple servers, and each of the servers is integrated with a process control component, and firstly, a first group of management components integrated in any server located in the first server group monitors and receives heartbeat messages sent by process control components in each server currently in the first server group, and obtains a process heartbeat message; wherein, the process heartbeat message includes an identifier corresponding to each process control component in the first server group and process status information of all controlled processes; then, the process status information in the process heartbeat message is detected according to the process status information in the process heartbeat message. Whether all controlled processes in each server of the server group have been started. If all controlled processes in each server of the first server group have not been started, a control message for shutting down the process is sent to the process control component in each server of the first server group to shut down all controlled processes in each server of the first server group, and then the heartbeat information of the current first group management component is sent to the second group management component to switch the second server group to the main server group through the second group management component and start all controlled processes in each server of the second server group; the second group management component is a group management component integrated in any server of the second server group. The embodiment of the present application integrates a process control component in each server in the two server groups, and integrates a group management component in any server in the two server groups. Through any group of management components, the process control components of each server in the server group can be monitored, and based on the monitored process status information, it is detected whether there is an unstarted application software process in the current server group. If so, the other group of management components is notified to realize the master-slave switching of the server group. Since the controlled process does not depend on the component itself, that is, there is no need to redevelop the controlled process, the decoupling of the component and the controlled process is realized, thereby reducing the complexity of the master-slave switching and improving the efficiency of the master-slave switching. At the same time, it can also ensure that only one server group is running and the other is in a standby state.

[0061] The embodiment of the present application discloses a specific method for active / standby switching of a server group, which is applied to an active / standby switching system including a first server group and a second server group, wherein the first server group and the second server group each include multiple servers, and each of the servers is integrated with a process control component, see Figure 4 As shown, the method includes:

[0062] Step S21: Monitor and receive heartbeat messages sent by process control components in each server in the first server group through the first group of management components integrated in any server located in the first server group, and obtain process heartbeat messages; wherein, the process heartbeat messages include identifiers corresponding to each process control component in the first server group and process status information of all controlled processes; the controlled processes are processes in the aviation ground service station software.

[0063] Step S22: detecting whether all controlled processes in the servers of the first server group have been started according to the process status information in the process heartbeat message.

[0064] Step S23: If all controlled processes in each server in the first server group are not started, a control message for shutting down the process is sent to the process control component in each server in the first server group to shut down all controlled processes in each server in the first server group.

[0065] Step S24: Obtain the heartbeat information of the first group of management components, obtain the current heartbeat information, and send the current heartbeat information to the second group of management components; the current heartbeat information includes the operating status information of the first group of management components and the corresponding master-slave priority; the second group of management components is a group management component integrated in any server located in the second server group.

[0066] In this embodiment, after closing all controlled processes in each server in the first server group, the heartbeat information of the current first group management component is obtained, and the current heartbeat information including the operating status information of the first group management component and the corresponding master-slave priority (the priority is used to indicate that the first server group is currently a backup server group) is obtained, and then the above-mentioned current heartbeat information is sent to the second group management component integrated in any server located in the second server group.

[0067] Step S25: When the second group management component receives the current heartbeat information, it switches the second server group to the main server group, and sends a control instruction for starting the process to the process control component in each server located in the second server group, so as to start all controlled processes in each server in the second server group.

[0068] In this embodiment, when the second group of management components receives the current heartbeat information sent by the first group of management components, it first switches the second server group to the main server group, and then sends a control instruction for starting all controlled processes to the process control components in each server located in the above two server groups, thereby starting all controlled processes in each server in the above second server group, completing the entire master-slave switching process.

[0069] For more specific processing procedures of the above steps S21 to S23, reference may be made to the corresponding contents disclosed in the above embodiments, which will not be described again here.

[0070] It can be seen that the controlled process in the embodiment of the present application is a process in the aviation ground service station software. By integrating a process control component in each server in the two server groups and integrating a group management component in any server in the two server groups, any group of management components can not only monitor the process control components of each server in the server group, but also detect whether there is an unstarted application software process in the current server group based on the monitored process status information. If so, the other group of management components is notified to realize the master-slave switching of the server group. The present application realizes the complete decoupling of components and controlled processes, reduces the complexity of master-slave switching, improves the efficiency of master-slave switching, and can also ensure that only one server group is running and the other is in standby status, solving the problem that the current aviation ground service station master-slave switching system cannot ensure that only one server group is running.

[0071] Accordingly, the embodiment of the present application further discloses a server group active / standby switching device, which is applied to an active / standby switching system including a first server group and a second server group, wherein the first server group and the second server group each include multiple servers, and each of the servers is integrated with a process control component, see Figure 5 As shown, the device includes:

[0072] A monitoring and receiving module 11 is configured to monitor and receive heartbeat messages sent by process control components in each server in the first server group through a first group management component integrated in any server in the first server group, thereby obtaining a process heartbeat message; wherein the process heartbeat message includes an identifier corresponding to each process control component in the first server group and process status information of all controlled processes;

[0073] A detection module 12 is configured to detect whether all controlled processes in the servers of the first server group have been started according to the process status information in the process heartbeat message;

[0074] a control message sending module 13 configured to send a control message for shutting down a process to a process control component in each server in the first server group if all controlled processes in each server in the first server group are not started, so as to shut down all controlled processes in each server in the first server group;

[0075] The heartbeat information sending module 14 is used to send the heartbeat information of the current first group management component to the second group management component, so as to switch the second server group to the main server group through the second group management component and start all controlled processes in each server in the second server group; the second group management component is a group management component integrated in any server located in the second server group.

[0076] Among them, the specific work processes of the above modules can refer to the corresponding contents disclosed in the aforementioned embodiments, which will not be repeated here.
