Description

TECHNICAL FIELD

[0001] The present application relates to the field of computers, in particular to a server detection method and device, a storage medium and an electronic device. BACKGROUND

[0002] In the high-availability architecture of a server cluster, the traditional server health detection mechanism often relies on the agent end sending a probe request to the backend server to evaluate the running state of the server. This method requires the backend server to design and expose a special port path for receiving and responding to the health check signal of the agent. The agent end collects response information by periodically sending requests to these paths and determines the health status of the server according to the preset strategy. However, the implementation of this mechanism intensifies the coupling between the agent end and the backend server, especially in the configuration level. Any inconsistency in the configuration can lead to false judgment of the health status, thereby affecting the stability and reliability of the entire cluster.

[0019] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative work should fall within the scope of protection of the present application.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but can include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] Optionally, as an optional solution, as shown in Figure 1 the server detection method comprises:

[0022] S102, the target server sends a target state detection request to the reference server through the target proxy server at a first time point, wherein the state detection message is used to obtain state information of the reference server, the target server and the reference server belong to the target server cluster, and the target proxy server is a proxy server configured for the target server cluster.

[0023] Optionally, in some embodiments, the server detection method described above can be applied in the application scenario of the server detection method, but is not limited to the application scenario. The application scenario is mainly in a distributed server cluster environment, especially in a server cluster under a cloud platform, a data center or a high-availability architecture, to ensure the health status of the server and the stable operation of the cluster.

[0024] It should be noted that in some embodiments, the target server described above can be used to indicate a server for health status detection, which is built-in with a target server detection module responsible for sending a state detection request to other servers in the cluster. In addition, the target server detection module can also be used to receive a state detection request sent by other servers in the target server cluster. The reference server described above can be used to indicate one of the other servers in the target server cluster detected by the target server.

[0025] Further, the target proxy server described above can be used to indicate a proxy server shared by the target server cluster, which is responsible for forwarding traffic and relaying health check requests. In this embodiment, the target proxy server forwards the target state detection request through a normal business traffic forwarding channel without creating a dedicated health detection channel.

[0026] It should be noted that the target server described above can periodically perform health detection on the reference server according to a target period. Correspondingly, other servers in the target server cluster also periodically perform health detection on the target server. In other words, in some embodiments, any server in the target server cluster can periodically perform health detection on other servers in the target server cluster, and can also be health detected by other servers in the target server cluster, which is not limited in this embodiment.

[0027] For example, as shown in Figure 2 , the target proxy server 202 can send and receive health detection messages to the target server detection module 204-1 configured in the target server 204 through the business traffic forwarding channel. At the same time, the business interface 204-2 of the target server 204 also sends and receives business traffic through the target proxy server through the business traffic forwarding channel.

[0028] S104, if the target server has not received the reference status information returned by the reference server through the target proxy server at the second time, it is determined that the reference server is in an abnormal state, wherein the second time is later than the first time, and the time interval between the second time and the first time is greater than the target interval.

[0029] It should be noted that the aforementioned target status detection request can be, but is not limited to, a request sent by the target server to the reference server through the target proxy server to obtain its status information, such as an HTTP request. The aforementioned reference status information is the status information returned by the reference server to the target server after receiving the target status detection request, used to characterize its current operating status. The aforementioned status identification information is a specific identifier carried in the reference status information, such as an HTTP status code, used to determine whether the reference server is operating normally.

[0030] S106, if the target server receives the reference status information returned by the reference server through the target proxy server before the second time, obtain the status identifier information carried in the reference status information; if the status identifier information matches the target status identifier information, determine that the reference server is in normal operating state; if the status identifier information does not match the target status identifier information, determine that the reference server is in abnormal state.

[0031] It should be noted that, in the case of the status identifier information being an HTTP status code, the aforementioned target status identifier information can be a status code used to indicate that the server is functioning normally, such as status code 200.

[0032] Optionally, but not limited to, the above steps can be explained using distance-based examples:

[0033] Initialization configuration: Configure the target server detection module for target server 1, set the IP address of the target proxy server to 10.1.1.1, the fixed path to / health, and set the target interval to 3 seconds.

[0034] Target status detection request sending: At any first moment, the transmitter in the target server detection module of target server 1 sends an HTTP request to the / health path of 10.1.1.1. The request contains the identifier of target server 1 and the identifier of target server 2 to be detected.

[0035] Waiting interval for target: After sending the request, target server 1 starts timing and waits for the target interval of 3 seconds in order to receive the response from target server 2.

[0036] Receiving and analyzing reference state information: if a response of the target server 2 is received within the target interval, the determinator in the target server detection module analyzes the state information in the response, such as the HTTP status code being 200, indicating that the target server 2 is in a normal operation state; if not 200, it is determined to be an abnormal state.

[0037] Processing if reference state information is not received: if any response of the target server 2 is not received after the end of the target interval, the determinator in the target server detection module directly marks the state of the target server 2 as abnormal, and triggers the disaster recovery processing flow.

[0038] It should be noted that the above examples are provided for the convenience of explaining the above steps, and there is no limitation on the above server detection method.

[0039] In the embodiment of the present application, the target server sends a target state detection request to the reference server through the target proxy server at the first time, wherein the state detection message is used to obtain the state information of the reference server, the target server and the reference server belong to the target server cluster, and the target proxy server is a proxy server configured for the target server cluster; in the case that the target server has not received the reference state information returned by the reference server through the target proxy server at the second time, it is determined that the reference server is in an abnormal state, wherein the second time is later than the first time, and the time interval between the second time and the first time is greater than the target interval; in the case that the target server receives the reference state information returned by the reference server through the target proxy server before the second time, the state identification information carried in the reference state information is obtained; in the case that the state identification information matches the target state identification information, it is determined that the reference server is in a normal operation state; in the case that the state identification information does not match the target state identification information, it is determined that the reference server is in an abnormal state. In other words, by decentralizing the initiation right and the determination right of health detection to the backend server, a more loosely coupled, efficient and accurate server cluster health detection mechanism is realized, the stability and disaster recovery capability of the entire server cluster are significantly improved, and the configuration complexity and the replacement cost of the proxy server are reduced. The health state misjudgment problem caused by the tight coupling of the configuration level of the proxy end and the backend server in the server detection method provided in the related art is solved, thereby affecting the stability of the server cluster.

[0040] Optionally, as an optional solution, the target server sends a target state detection request to the reference server through the target proxy server at the first time, which includes:

[0041] The target server detection module configured in the target server sends a target state detection request to the reference server detection module configured in the reference server through the target proxy server at a first time, wherein the target state detection request carries a reference network address of the reference server detection module and a port identifier of a detection port configured for the reference server detection module.

[0042] It should be noted that the target server detection module is a software module built-in the target server, which is responsible for periodically sending health check requests to other servers in the target server cluster, receiving and processing health state responses of other servers, and performing state judgment and disaster recovery processing according to the received health state information.

[0043] Correspondingly, the reference server detection module is a software module built-in the reference server, which is responsible for periodically sending health check requests to other servers in the target server cluster, receiving and processing health state responses of other servers, and performing state judgment and disaster recovery processing according to the received health state information.

[0044] Optionally, the server health detection program (including the target server detection module and the reference server detection module) can but is not limited to include, as shown in Figure 3 including:

[0045] The transmitter 302 is configured to send detection requests, for example, to send http requests to a fixed path of a certain IP address at a fixed frequency, and to pass the corresponding status code and the corresponding address in the request result to the determinator. The fixed frequency does not need to be configured and can be set internally, for example, 2 times per second; the certain IP needs to be configured as the IP address of the proxy, and no matter what kind of proxy implementation is used, it has IP attribute, so this configuration does not exist binding, and the proxy can be replaced at any time; the fixed path is built-in as the path of the receiver.

[0046] The receiver 304 is configured to receive health state responses, for example, to give a web interface, receive http requests, and return the local IP as the result to the other party.

[0047] The determinator 306 is configured to determine the health state, for example, to receive the IP and state information passed by the transmitter, and to mark the IP as online or offline according to the built-in determination rule. For example, if no return of a certain IP is received for 3 seconds in succession, it is marked as offline; if a normal return is received once, it is marked as online.

[0048] The state maintainer 308 is configured to store all backend node IPs and health states, which is essentially a memory space that maintains the determination results of the determinator.

[0049] Disaster recovery processor 310 is used to execute disaster recovery strategy when the backend node is abnormal, for example, subscribe to health state change event in state maintenance ware, so as to trigger different actions, this part can be realized by user according to self business, disaster recovery execution form includes but not limited to script, webhook and the like.

[0050] Optionally, the above steps can be exemplarily explained by the following examples, but not limited to:

[0051] S1, environment configuration environment: a target server cluster under a cloud platform, which includes target server 1, target server 2 to target server N, and target proxy server (such as load balancer). The IP address of the target proxy server is 10.1.1.a, and the IP address of the target server 1 is 10.1.1.b. It is assumed that the target server 1 needs to detect the health status of the target server 2, and the IP address of the target server 2 is 10.1.1.c, and the detection port is 8080.

[0052] S2, target state detection request sending request time: the first time is set as the current time, such as 2023-04-0110:00:00. Transmitter: the transmitter module on the target server 1 starts to work, which sends a target state detection request to the detection port 8080 of the target server 2 through the target proxy server 10.1.1.a. Request content: the target state detection request contains a specific HTTP request, for example, a GET request to / health path, and carries the identification of the target server 1 and the reference network address (IP: 10.1.1.c) of the target server 2 and the detection port identification (port: 8080) in the request header.

[0053] S3, state detection request forwarding the target proxy server 10.1.1.a receives the target state detection request, and based on the built-in forwarding rules, forwards the request to the detection port 8080 of the target server 2. The receiver module of the target server 2 receives the request and processes it, and then returns an HTTP response on the / health path through the transmitter module, which contains state identification information, such as HTTP status code 200 indicating normal operation, or 500 indicating internal server error.

[0054] S4, the receiver module of the target server 1 receives the response forwarded by the target proxy server, and transmits the state identification information in the response to the determinator. The determinator determines the health state of the target server 2 according to the built-in determination rule, such as marking as abnormal if 200 status code response is not received for three times in succession. State information maintenance: if the state identification information of the target server 2 indicates that it is in a normal operation state, the state maintainer updates the health state information of all backend nodes in the cluster, and marks the state of the target server 2 as normal. If the state identification information indicates abnormality, the state maintainer marks the state of the target server 2 as abnormal, and triggers the disaster recovery strategy of the disaster recovery processor.

[0055] S5, disaster recovery processing flow The disaster recovery processor subscribes to the health state change event in the state maintainer, and once it detects that the state of the target server 2 is determined to be abnormal, it performs the predefined disaster recovery operation, such as automatically executing the “restart service” script to attempt to restore the service of the target server 2. Alternatively, if the target server 2 cannot be restored by restarting, the disaster recovery processor can perform a more complex disaster recovery strategy, such as redirecting traffic to other healthy servers in the cluster to ensure service continuity and high availability.

[0056] It should be noted that the above example is an optional example provided for the convenience of explaining the above steps, and there is no limitation on the detection method of the above server.

[0057] By defining the target server detection module and the reference server detection module, the initiation and response responsibilities of health detection are clearly divided, making the health check mechanism more modular and manageable. At the same time, the reference network address and port identifier carried in the target state detection request ensure the accuracy and pertinence of the request, avoiding the problem of misfiring or response mismatch, and improving the accuracy and efficiency of health detection.

[0058] Optionally, as an optional solution, in the case that the target server has not received the reference state information returned by the reference server through the target proxy server at the second time, determining that the reference server is in an abnormal state comprises: in the case that the target server detection module has not received the reference state information returned by the reference server detection module through the target proxy server at the second time, determining that the reference server is in an abnormal state.

[0059] In a case where the target server receives the reference state information returned by the reference server through the target proxy server before the second time point, the obtaining of the state identifier information carried in the reference state information comprises: in a case where the target server detection module receives the reference state information returned by the reference server detection module through the target proxy server before the second time point, the obtaining of the state identifier information carried in the reference state information;

[0060] In a case where the state identifier information matches the target state identifier information, the determining of the reference server as being in a normal state comprises: in a case where the state identifier information matches the target state identifier information, the target server detection module determines the reference server as being in a normal state.

[0061] In a case where the state identifier information does not match the target state identifier information, the determining of the reference server as being in an abnormal state comprises: in a case where the state identifier information does not match the target state identifier information, the target server detection module determines the reference server as being in an abnormal state.

[0062] It should be noted that the target server detection module receives the above-mentioned reference state information through the receiver, and determines the running state of the reference server by using the determinator.

[0063] By using the embodiment of the present application, the target server detection module performs health check, which can not only accurately identify the abnormal state of the reference server, but also accurately distinguish the normal running state and the abnormal state based on the matching of the state identifier information. This enables the disaster recovery processor to make disaster recovery decisions more quickly and accurately, such as automatically isolating the abnormal server, reallocating traffic, etc., thereby further enhancing the stability and disaster recovery capability of the server cluster.

[0064] Optionally, as an optional solution, after determining that the reference server is in an abnormal state, the method further comprises:

[0065] reporting, by the target server detection module, abnormal prompt information to a cluster maintenance system for maintaining the target server cluster, wherein the abnormal prompt information is used to prompt a storage fault of the reference server.

[0066] It should be noted that in some embodiments, the target server detection module can but is not limited to report the above-mentioned abnormal prompt information through the disaster recovery processor. The above-mentioned cluster maintenance system can but is not limited to a system responsible for detecting and managing the running state of the entire target server cluster, including but not limited to functions such as fault detection, resource allocation, cluster configuration management, etc. It is usually an important tool for cluster operation and maintenance, and can receive health state reports and abnormal information from each server in the cluster.

[0067] Further, when the target server detects that the reference server is in an abnormal state, the target server detection module generates and sends prompt information. The prompt information may include, but is not limited to, the identification (such as an IP address) of the reference server, a description of the abnormal state (such as a storage failure), and detailed information such as a possible abnormal timestamp, for further positioning and processing of the problem by the cluster maintenance system, which is not limited in the embodiment.

[0068] In the embodiment, after the target server detection module determines that the reference server is in an abnormal state, the abnormal prompt information is reported to the cluster maintenance system, so as to timely notify the operation and maintenance personnel or the monitoring system, realize rapid positioning and processing of the fault, reduce the influence range and duration of the fault, and improve the management and maintenance efficiency of the cluster.

[0069] Optionally, as an optional solution, the server detection method further includes:

[0070] The target server is configured with a target server detection module, wherein the target server detection module is configured to send a state detection message to a server other than the target server in the target server cluster, to detect the running state of the server other than the target server in the target server cluster, and the target server detection module is further configured to receive a state detection request sent by the server other than the target server in the target server cluster;

[0071] The target server detection module is configured with a network address and a detection port.

[0072] It should be noted that in the embodiment, the network address configuration is a network address required by the target server detection module, which is usually an IP address, and is used to receive the state detection request sent by the other server. The module may also need to know the network address of the other server in order to actively send a health check request. The detection port is a specific port number, and the target server detection module listens to the state detection request on the port, and the other server sends the state detection request to the target server through the port. The detection port ensures the distinction between the health check request and other service requests, and avoids unnecessary interference.

[0073] In the embodiment, the target server is configured with the target server detection module, the network address, and the detection port, which not only simplifies the configuration process of the health detection, but also improves the flexibility and expansibility of the configuration, makes it more convenient to add or replace servers in the server cluster, and reduces the risk of health detection misjudgment caused by configuration errors.

[0074] Optionally, as an optional solution, the server detection method further includes:

[0075] In a case where the target server receives the reference state detection request sent by the reference server through the target proxy server, the target proxy server sends target state information for responding to the reference state detection request to the reference server, wherein the target state information is used to represent the running state of the target server, and in a case where the reference server receives the target state information, the running state of the target server is determined according to the target state information.

[0076] Optionally, in some embodiments, the reference state detection request is used to indicate a request sent by the reference server to the target server, and the purpose is to obtain the running state information of the target server. The target state information can be, but is not limited to, information returned by the target server in response to the reference state detection request, and is used to represent the running state of the target server, and can include HTTP identification code and other information, which is not limited in this embodiment.

[0077] By using the embodiment of the present application, the ability of the target server to respond to the detection request of the reference server is increased, that is, the target server can send target state information reflecting the running state of the target server to the reference server through the target proxy server. This bidirectional health check mechanism not only strengthens the health state synchronization between the servers in the cluster, but also provides more detailed health state information, which helps the disaster recovery processor to make more accurate decisions, and further improves the disaster recovery management capability of the cluster.

[0078] Optionally, as an optional example, the detection method of the server can be exemplarily explained based on the following example as shown in Figure 4

[0079] As shown in Figure 4 The proxy server of the target server cluster is proxy server A, and the target server cluster includes N servers, including server 1, server 2 to server N; the server 1, the server 2 to the server N are all configured with a business port and a server health detection program (used to represent a server detection module); the server 1, the server 2 to the server N all use the business interface configured by each server to receive and send the business traffic received and sent through the forwarding channel of the proxy server A, and the server 1, the server 2 to the server N all use the server health detection program configured by each server to receive and send the health detection message received and sent through the forwarding channel of the proxy server A.

[0080] It should be noted that the above example is an optional example provided for the purpose of explaining the above steps, and the detection method of the server is not limited in any way.

[0081] ​It should be noted that, for the foregoing method embodiments, for the sake of simple description, they are all described as a combination of a series of actions, but those skilled in the art should know that the present application is not limited to the action sequence described, because according to the present application, certain steps can be performed in other sequences or simultaneously. Secondly, those skilled in the art should know that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily necessary for the present application.

[0082] According to another aspect of the embodiments of the present application, a detection device for implementing the detection method of the server is also provided. As shown in the figure, the device comprises: Figure 5

[0083] The sending unit 502 is configured to send a target state detection request to the reference server through the target proxy server at the first time, wherein the state detection message is used to obtain the state information of the reference server, the target server receiving the state detection message and the reference server both belong to the target server cluster, and the target proxy server is a proxy server configured for the target server cluster.

[0084] The first determination unit 504 is configured to determine that the reference server is in an abnormal state if the reference server returns the reference state information through the target proxy server at the second time, wherein the second time is later than the first time, and the time interval between the second time and the first time is greater than the target interval.

[0085] The second determination unit 506 is configured to obtain the state identification information carried in the reference state information if the target server receives the reference state information returned by the reference server through the target proxy server before the second time. If the state identification information matches the target state identification information, it is determined that the reference server is in a normal operating state.
