Description
Technical Field
The present application relates to the field of data processing technologies, and in particular, to a method and an apparatus for processing a service request, an electronic device, and a readable storage medium.
Background
The internet technology is changing day by day, and the life of people is greatly enriched. With the increase of the access amount, most of internet services adopt a distributed cluster mode to provide services to the outside, so that the concurrency performance and the service reliability are improved.
However, in a cluster, there may be a case where a certain node is separated from other nodes in the cluster due to a network disconnection or other split scenes. At present, after the situation occurs, the detached node can still provide data service for the user, but since the detached node cannot perform normal data synchronization with the rest of nodes, the service provided for the user is inconsistent, and thus normal operation of the whole cluster is affected.
Disclosure of Invention
An object of the embodiments of the present application is to provide a method and an apparatus for processing a service request, an electronic device, and a readable storage medium, so as to solve the problem that, in the related art, services provided to a user may be inconsistent, thereby affecting normal operation of a whole cluster.
The embodiment of the application provides a service request processing method, which is applied to service distribution equipment and comprises the following steps:
when a service request is received, determining an effective processing node; the effective processing node is a node which can perform data synchronization with other nodes in the cluster in which the service request needs to access;
and sending the service request to the effective processing node.
In the implementation process, the service request first arrives at the service distribution device, the service distribution device determines an effective processing node for the service request (i.e., determines a processing node in the cluster that can keep data synchronization with other nodes in the cluster and is not separated from other nodes in the cluster), and at this time, the service request is sent to the effective processing node. Therefore, through regulation and control management of the service distribution equipment, the service requests are processed by the effective processing nodes in the cluster, and because the data among the effective processing nodes are always kept synchronous, the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.
Further, the determining the valid processing node when receiving the service request includes: when a service request is received, allocating a processing node for the service request; determining whether a preset validity flag can be detected from the processing node; the validity identification is an identification generated when the processing node can perform data synchronization with the rest of the nodes in the cluster; when the preset validity identification can be detected, determining the processing node as the valid processing node; and when the preset validity identification cannot be detected, reallocating the processing node for the service request, and determining whether the preset validity identification can be detected from the reallocated processing node.
In the implementation process, the service request first arrives at the service distribution device, the service distribution device distributes a processing node for the service request, and after the processing node is distributed, before the service request is sent to the processing node, whether a preset validity flag can be detected in the processing node (i.e., whether the processing node can keep data synchronization with other nodes in the same cluster is determined), when the validity flag is confirmed, the processing node can keep data synchronization with other nodes in the same cluster is indicated, and at this time, the processing node is taken as a valid processing node, so that the service request is sent to the processing node. And once the validity identification does not exist, the processing node is indicated to be incapable of keeping data synchronization with other nodes in the same cluster, the processing node is separated from other nodes in the cluster, and at the moment, if the processing node processes the service request, the consistency of the service provided for the user cannot be ensured, so that the processing node can be allocated to the service request again, and whether the preset validity identification can be detected from the allocated processing node or not can be determined again. Therefore, through regulation and control management of the service distribution equipment, the service requests are processed by the effective processing nodes in the cluster, and because the data among the effective processing nodes are always kept synchronous, the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.
Further, the validity mark indicates that a preset port of the processing node is in an enabled state; the determining whether a preset validity flag can be detected from the processing node comprises: requesting the processing node to call the preset port; when the response of the preset port is received, determining that the preset validity identification can be detected; otherwise, determining that the preset validity mark cannot be detected.
In the implementation process, by setting the processing nodes in the cluster, when the processing nodes can keep data synchronization with other nodes in the cluster, even if the preset port is in the enabled state. Therefore, the service distribution equipment can easily determine the starting state of the preset port in the processing node by requesting to call the corresponding preset port, so as to determine whether the processing node can be used as an effective processing node. The whole scheme is simple to realize and has higher practical application value.
Further, the determining the valid processing node when receiving the service request includes: when a service request is received, acquiring a processing node which currently has a preset validity identifier in the cluster; the validity identification is an identification generated when the processing node can perform data synchronization with the rest of the nodes in the cluster; selecting one processing node from the processing nodes with the validity identification as the valid processing node.
In the implementation process, the service request first reaches the service distribution device, the service distribution device first acquires the processing nodes currently having the preset validity identifier in the cluster, and then selects one processing node from the processing nodes having the validity identifier as an effective processing node, and sends the service request to the effective processing node. Therefore, the processing nodes for processing the service request are guaranteed to be processed by the effective processing nodes in the cluster, and the data among the effective processing nodes are always kept synchronous, so that the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.
The embodiment of the present application further provides a service request processing method, which is applied to a processing node of a cluster, and includes:
detecting whether data synchronization can be carried out with other nodes in the cluster;
when the data synchronization with other nodes in the cluster can be carried out, a preset validity identification is kept, and when the data synchronization with other nodes in the cluster cannot be carried out, the preset validity identification is eliminated, so that the service distribution equipment sends the received service request to other nodes with the validity identification in the cluster when the preset validity identification is not detected.
In the implementation process, the processing node in the cluster may detect whether the processing node can perform data synchronization with other nodes in the cluster, and if not, it indicates that the processing node has separated from other nodes in the cluster, and there may be a split brain. At this time, the preset validity flag is removed, so that the service allocation device allocates the service request to other nodes having validity flags in the cluster when allocating the service request, so that the service request can be processed by valid processing nodes (i.e., processing nodes having validity flags) in the cluster, and since data between the valid processing nodes are always synchronized, the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.
Further, the validity flag indicates that a preset port of the processing node is in an enabled state.
In the implementation process, when the processing node can keep data synchronization with other nodes in the cluster, even if the preset port is in the enabled state. Therefore, the service distribution equipment can easily determine the state of the preset port in the processing node by requesting to call the corresponding preset port, so as to determine whether the processing node can be used as an effective processing node, thereby the whole scheme is simple to realize and has higher practical application value.
Further, when data synchronization with other nodes in the cluster is not possible, the service request processing method further includes: and restarting the processing node.
In the implementation process, when detecting that the processing node cannot perform data synchronization with other nodes in the cluster, the processing node automatically restarts to attempt to re-establish contact with other nodes in the cluster so as to re-implement data synchronization. Therefore, self-healing of the processing nodes can be achieved to a certain extent, and reliability of the whole cluster is improved.

Therefore, through regulation and control management of the service request processing device, the service requests are processed by the effective processing nodes in the cluster, and data among the effective processing nodes are kept synchronous all the time, so that the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.

Detailed Description
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.
The first embodiment is as follows:
it should be understood that in practical applications, a processing node in a cluster may be disconnected from the rest of the nodes in the cluster due to a network disconnection, etc., and at this time, the node cannot synchronize data with the rest of the nodes in the cluster. For example, referring to fig. 1, assuming that the processing node 3 is disconnected (the circle at the data synchronization position in the figure is marked with an exclamation mark to indicate that the processing node 3 is disconnected), but at this time, the processing node 3 may still provide service for the user, which may cause that, since the processing node 3 cannot perform data synchronization with the processing nodes 1 and 2, after respective data operations are performed, the data in the processing node 3 is inconsistent with the data in the processing nodes 1 and 2, in this case, for a service request, the processing result of the processing node 3 may be inconsistent with the processing results of the processing nodes 1 and 2, that is, the service provided to the user is inconsistent, so that the reliability of the cluster is reduced, and the normal operation of the cluster is affected.
In order to solve the problem, an embodiment of the present application provides a service request processing method. As shown in fig. 2 and fig. 3, fig. 2 is a schematic flow chart of a service request processing method applied to a processing node of a cluster provided in this embodiment, and fig. 3 is a schematic flow chart of a service request processing method applied to a service distribution device provided in this embodiment.
S201: the processing node detects whether the processing node can perform data synchronization with other nodes in the cluster.
It should be noted that the processing node described in this embodiment of the present application is a node that can perform service processing (e.g., perform operations such as data reading and writing) in a cluster. The node may be a server or other device capable of performing service processing.
In this embodiment of the present application, a cluster detection program may be configured in advance in each service processing node in a cluster, and the cluster detection program automatically performs detection on whether the cluster detection program can perform data synchronization with other nodes in the cluster. In this embodiment of the present application, the cluster detection program may continuously run from the time when the processing node is started, and the manner of detecting whether or not it can perform data synchronization with other nodes in the cluster includes, but is not limited to, detecting whether or not it can normally communicate with other nodes in the cluster, and when it cannot normally communicate with other nodes in the cluster, it is considered that it cannot perform data synchronization with other nodes in the cluster.
S202: and when the data synchronization with other nodes in the cluster can be carried out, keeping the preset validity identification, and when the data synchronization with other nodes in the cluster cannot be carried out, eliminating the preset validity identification.
In the embodiment of the present application, the validity flag is a predefined flag generated when the processing node can perform data synchronization with the other nodes in the cluster.
In the embodiment of the present application, a port may be pre-designated, and whether the processing node itself can perform data synchronization with other nodes in the cluster is characterized by the state of whether the port is enabled or not. For example, the port may be controlled to remain in the enabled transition state when the processing node itself can synchronize data with other nodes in the cluster, and to remain in the closed state when it is detected that the processing node itself cannot synchronize data with other nodes in the cluster. It should be understood that, in an actual application process, the range of the port numbers of the system is 0 to 65535, wherein some of the ports have special system definitions, if such ports are selected to characterize whether the processing node itself can perform data synchronization with other nodes in the cluster, a system conflict may be caused, otherwise, the original protocol definition of the port needs to be modified. To avoid the foregoing situation, the ports pre-designated in the embodiment of the present application may be selected from ports that can be freely allocated by the processing node, for example, ports 5000 to 65535. It should be further noted that, in the embodiment of the present application, the control of enabling or closing the pre-specified port may be implemented by calling an extended internet daemon (a new generation of network daemon service program).
It should be noted that, in the embodiment of the present application, in addition to the above-mentioned enabled state through the port as the validity flag, the validity flag may also be implemented in other ways. For example, when the processing node initially detects that data synchronization with other nodes in the cluster can be performed, a specific identifier may be generated in the node and stored at a specified location, so that when the service distribution device needs to determine whether the processing node can be used as a valid processing node (the valid processing node needs to be a processing node that can perform data synchronization with other nodes in the cluster), the service distribution device can obtain the specific identifier from the specified location; and when the processing node detects that data synchronization with other nodes in the cluster cannot be carried out, the specific identifier is cleared from the designated position, so that the service distribution equipment cannot acquire the specific identifier from the designated position. It should be understood that, in the embodiment of the present application, as long as the processing node can be characterized to perform data synchronization with other nodes in the cluster, and the validity identifier that can be acquired by the service distribution device can be adopted by the application.
It should be noted that, in this embodiment of the present application, the service allocating apparatus may receive a service request, and determine whether to allocate the received service request to each processing node for processing according to whether the valid identifier exists in the processing node. The operations performed by the service distribution equipment can be seen in fig. 3:
s301: upon receiving a service request, a valid processing node is determined.
It should be understood that, in the present application and embodiment, in the cluster to which the active processing node needs to access for the service request, the node may perform data synchronization with the rest of the nodes in the cluster. As can be seen from the above description of fig. 2, each processing node in the cluster maintains the preset validity flag when the processing node can perform data synchronization with other nodes in the cluster, and eliminates the preset validity flag when the processing node cannot perform data synchronization with other nodes in the cluster. Therefore, in the embodiment of the present application, whether a processing node can be a valid processing node can be determined by determining whether a preset validity flag exists in each processing node.
Illustratively, in a possible implementation of the embodiment of the present application, as shown in fig. 4, the method includes:
s401: and allocating a processing node for the service request.
The service allocation device may allocate a processing node for the service request when receiving the service request.
S402: it is determined whether a preset validity flag can be detected from the assigned processing node. When the validity flag can be detected, go to step S403; when the validity flag cannot be detected, the process goes to step S401 to re-assign the processing node to the service request.
It should be noted that, in this possible embodiment, the service allocating apparatus may mark the processing node when the validity flag in the allocated processing node cannot be detected, so that when the processing node is newly allocated to the service request, the service allocating apparatus reallocates the processing node from the processing nodes that are not marked in the cluster. It will be appreciated that the flag may be cleared after a valid processing node is determined.
S403: the allocated processing node is determined to be a valid processing node.
In the embodiment of the present application, after determining the valid processing node, the process goes to step S302.
In another possible implementation manner of the embodiment of the present application, when receiving a service request, the service distribution device may also try to detect, for each processing node in sequence, an validity flag of each processing node, so as to obtain a set of processing nodes currently having a preset validity flag in a cluster. And then selecting one processing node from the processing nodes with the preset validity identification as a valid processing node. It should be noted that, in this possible embodiment, one processing node may be randomly selected from the processing nodes currently having the preset validity flag as a valid processing node; or, the selection may be performed according to the current remaining processing amount of each processing node, for example, when the service distribution device detects the validity identifier of each processing node, the service distribution device may simultaneously obtain the remaining processing amount of each processing node (e.g., a CPU (central processing Unit/Processor) idle rate, a memory idle amount, and the like), and then select the processing node with the largest remaining processing amount and the preset validity identifier as the valid processing node. It should be understood that, in the present possible embodiment, the selection manner is not limited, as long as one processing node can be selected as a valid processing node from the processing nodes currently having the preset validity flag.
In another possible implementation manner of the embodiment of the present application, before receiving the service request, the service distribution device may also detect, in real time, the validity identifier of each processing node in the cluster, so as to obtain, in real time, a set of processing nodes currently having a preset validity identifier in the cluster. When a service request is received, namely one processing node is selected from the processing nodes with preset validity identification currently, the processing node is used as a valid processing node.
It should be noted that, in a possible example of the embodiment of the present application, the validity flag in each of the above possible implementations may be that a preset port of the processing node is in an enabled state. At this time, when the service distribution device obtains the validity identifier, it may request the processing node to call the preset port. And when the response of the preset port is received, determining that the preset validity identification can be detected, otherwise, determining that the preset validity identification cannot be detected.
S302: the service request is sent to the active processing node.
It should be noted that, in the embodiment of the present application, the service distribution device may be a device having a function capable of implementing the service request distribution, for example, may be a load balancer, or an electronic device (such as a server or the like) loaded with load balancing software.
Through the scheme, the service distribution equipment can distribute the received service request to the effective processing nodes for processing, and the data among the effective processing nodes are always kept synchronous, so that the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.
It is worth noting that in the embodiment of the present application, when each processing node in the cluster detects that it cannot perform data synchronization with other nodes in the cluster, it may also control itself to restart, so as to try to establish contact with other nodes in the cluster again, so as to achieve data synchronization again. Therefore, self-healing of the processing nodes is realized to a certain extent, and the reliability of the whole cluster is improved.
It should be further noted that, in a feasible implementation manner of the embodiment of the present application, if a processing node cannot perform data synchronization with other nodes in the cluster after being restarted for n times continuously, a fault notification may be performed according to a preset manner, for example, an operation and maintenance person is notified in a manner of WeChat, short message, mail, or the like, so that the operation and maintenance person can perform manual repair as long as the processing node has a fault that cannot be self-healed.
To sum up, in the service request processing method provided in this embodiment of the present application, a service request first arrives at a service distribution device, and the service distribution device determines an effective processing node for the service request (i.e., determines a processing node in a cluster that can maintain data synchronization with other nodes in the cluster and is not detached from other nodes in the cluster), and then sends the service request to the effective processing node. Therefore, through regulation and control management of the service distribution equipment, the service requests are processed by the effective processing nodes in the cluster, and because the data among the effective processing nodes are always kept synchronous, the consistency of the service provided by the cluster can be improved, and the cluster can normally operate.
In addition, by the service request processing method provided by the embodiment of the application, the processing node which is separated from other nodes in the cluster can keep the separated data, and after recovery, data synchronization with other nodes can be easily realized only by normally acquiring data from other processing nodes, so that the data consistency in each processing node is ensured.
In addition, when detecting that the processing node cannot synchronize data with other nodes in the cluster, the processing node may automatically restart to attempt to re-establish contact with other nodes in the cluster to re-implement data synchronization. Therefore, self-healing of the processing nodes can be achieved to a certain extent, and reliability of the whole cluster is improved.
Example two:
in this embodiment, on the basis of the first embodiment, a case that a service request is a data read-write request, a processing node is a server, a service distribution device is a load balancer, and an effectiveness identifier is that an 8080 port of the server is in an enabled state is taken as an example, which is further exemplified by the present application.
Referring to fig. 5, the cluster has 3 processing nodes, i.e., server 1 to server 3, and each of the server 1 to server 3 runs a cluster detection program to detect whether it can perform data synchronization with the other processing nodes in the cluster. When the detection result of the cluster detection program is that the cluster detection program can perform data synchronization with the other processing nodes in the cluster, the 8080 port is controlled to be in an enabled state, for example, in the case of the server 1 and the server 2 in fig. 5, and when the detection result of the cluster detection program is that the cluster detection program cannot perform data synchronization with the other processing nodes in the cluster, the 8080 port is controlled to be in a closed state, for example, in the case of the server 3 in fig. 5. It should be noted that, for the activation and the deactivation of the 8080 port, the activation and the deactivation can be realized by calling xinetd. It should be noted that, when detecting that the cluster detection program in the server 3 cannot perform data synchronization with the other processing nodes in the cluster, the cluster detection program simultaneously controls itself to restart so as to attempt to recover data synchronization with the other processing nodes in the cluster.
Referring to fig. 5, a user accesses load balancing first, and the load balancer requests the 8080 ports of the servers 1 to 3, respectively, and at this time, the obtained request result is that the 8080 port in the server 3 does not respond, so that the load balancer distributes the data read-write request of the user to the server 1 or the server 2, but not to the server 3.
By the scheme, the consistency of the service provided by the cluster can be improved, the cluster can normally run, and meanwhile, the processing node separated from other processing nodes in the cluster can try to self-heal, so that the reliability of the cluster is improved.
