Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
In order to reduce the occurrence of the situation of unavailable service function, embodiments of the present invention provide a configuration updating method, an apparatus, a configuration server, a cache server, and a configuration system, which are described in detail below.
With the rise of micro-service application architecture, for application programs with multiple functions, multiple service programs may be corresponded in corresponding service servers, and each service program provides different functions for the application program, for example, for a certain short video application program, multiple service programs may be provided, and video recommendation, video approval, video comment and the like are provided respectively. By adopting the micro-service application architecture, different service programs can be split, so that the research and development efficiency of the service programs is improved.
The configuration updating method, the configuration updating device, the configuration server, the cache server and the configuration system provided by the embodiment of the invention can be applied to the configuration system in a micro-service architecture so as to reduce the occurrence of unavailable service functions.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a configuration server in the configuration system of fig. 1 applying the configuration updating method according to an embodiment of the present invention;
the method specifically comprises the following steps:
step 201, receiving a configuration update request sent by a service server to be configured in a plurality of service servers.
The service server to be configured may send the configuration update request to the configuration server at regular time according to a certain preset time length, or may send the configuration update request at irregular time according to needs.
Furthermore, one or more service program instances to be configured can run in the service server to be configured. The step of receiving a configuration update request sent by a service server to be configured in the plurality of service servers includes: and receiving a configuration updating request sent by a service program instance to be configured.
Specifically, the configuration update request may include information about a current configuration version of the service program instance to be configured, so that the configuration server may send, to the service program instance to be configured, latest version configuration information that is higher than the current configuration version.
Step 202, extracting a first license from a preset number of pre-established licenses with timestamp information corresponding to the latest version configuration information.
The first license is the license with the earliest timestamp information in the preset number of licenses; presetting the generation time of the latest version configuration information of the initial timestamp information of the licenses; the preset number is smaller than the total number of the service servers to be configured. The preset number of licenses having timestamp information corresponding to the latest version of configuration information may be generated and stored by the configuration server when the configuration server obtains the latest version of information, or may be generated and stored by another server by the configuration server sending a request to another server.
Step 203, determining whether the current time is later than or equal to the timestamp information of the first license.
If the current time is later than or equal to the timestamp information of the first license, executing step 204; if the current time is earlier than the timestamp information of the first license, go to step 206.
And step 204, sending the latest version configuration information to the service server to be configured so as to update the configuration of the service server to be configured.
Corresponding to step 201, since one or more service program instances to be configured may run in the service server to be configured, if the current time is greater than the timestamp information of the first license, the latest version configuration information is sent to the service program instance to be configured, so that the service program instance to be configured performs configuration update.
Step 205, a new second license corresponding to the latest version of configuration information is created, and the timestamp information of the second license is the time when the latest version of configuration information is sent to the service server to be configured plus a preset time interval.
Correspondingly, a new second license corresponding to the latest version of configuration information may be created, and the timestamp information of the second license is the time when the latest version of configuration information is sent to the service program instance to be configured plus a preset time interval.
For example, if the time of sending the latest version of configuration information to the service program instance to be configured is 7:00 am on 4/1/2019, and the preset time interval is 1 minute, the timestamp information of the second license is 7:01 am on 1/4/2019.
In step 206, if the current time is earlier than the timestamp information of the first license, a new third license corresponding to the latest version of configuration information is created and the configuration update is stopped, where the timestamp information of the third license is the timestamp information of the first license.
The initial timestamp information of the license is the generation time of the latest version of the configuration information, so that it can be known that the initial timestamp information of the license is earlier than the current time when the configuration update request is received, and meanwhile, the total number of the licenses is less than the total number of the service servers to be configured.
If the current time of receiving the configuration update request is later than or equal to the timestamp information of the first license, for example: if the timestamp information of the license is the initial timestamp information, it indicates that, before the current configuration update request, the number of the service servers to be configured, which have sent the configuration update request and obtained the latest version of configuration information, to the configuration server is less than the total number of the licenses, and at this time, the latest version of configuration information may be sent to the service servers to be configured, which sent the current configuration update request. Meanwhile, in order to prevent that, in a preset time interval, after the number of the service servers to be configured, which have sent the configuration update request and obtained the latest version configuration information, reaches the total number of the licenses, and the service servers to be configured, which have sent the configuration update request, obtain the latest version configuration information, a second license, which is delayed by the preset time interval after timestamp information, may be created, and in the preset time interval, the latest version configuration information is not sent to the service program instance corresponding to the second license.
If the current moment of receiving the configuration updating request is earlier than the timestamp information of the first license, it indicates that in a preset time interval, before the current configuration updating request, the configuration servers of the service servers to be configured, which have the same number as the total number of the licenses, have sent the configuration updating request, and obtain the configuration information of the latest version. At this time, the configuration update may be stopped to avoid that all the service servers to be configured providing the same service function perform the configuration update at the same time in the same time interval, and the service function is unavailable. Meanwhile, in order to restart sending the latest version of configuration information to the service server to be configured that sends the configuration update request after the preset time interval, a third license whose timestamp information is the timestamp information of the first license extracted this time may be created.
As can be seen from the foregoing embodiments, in the embodiments of the present invention, when receiving a configuration update request sent by a service server to be configured in a service server, a configuration server does not directly send latest version configuration information to the service server to be configured, but extracts a first license, and when a current time is earlier than timestamp information of the first license, it indicates that the service servers to be configured, which request configuration update in a preset time interval, have reached a preset number, and at this time, the configuration update is not performed on the service server to be configured, which sends the configuration update request, so that it is possible to avoid a situation that all service servers to be configured, which provide the same service function, perform configuration update simultaneously in the preset time interval, and the service function is unavailable, that is, to reduce occurrence of a situation that the service function is unavailable.
Referring to fig. 3, the present embodiment further provides a configuration system. As shown in fig. 3, the configuration system is added with a cache server 130 on the basis of the configuration system shown in fig. 1, and is used for storing a license with timestamp information, which is established in advance, corresponding to the configuration version, and when receiving a license creation request from the configuration server, performing corresponding license creation operation according to the request.
Referring to fig. 4, fig. 4 is a schematic flowchart illustrating that the configuration updating method according to the embodiment of the present invention is applied to a configuration server in the configuration system shown in fig. 3; the method comprises the following specific steps:
step 401, receiving a configuration update request sent by a service program instance to be configured.
Step 402, determine whether there is the latest version configuration information higher than the current version configuration of the service program to be configured. If the latest version configuration information higher than the current version configuration of the service program instance to be configured does not exist, executing step 403; if the latest version configuration information higher than the current version configuration of the service program instance to be configured exists, step 404 is executed.
At step 403, the configuration update is stopped.
Step 404, sending a license acquisition request for the latest version configuration information to the cache server, so that the cache server judges whether a priority queue corresponding to the latest version configuration information exists at the current moment; if the priority queue corresponding to the latest version configuration information exists, extracting a first license in a pre-established priority queue corresponding to the latest version configuration information, and returning the first license to the configuration server; and if the priority queue corresponding to the latest version of configuration information does not exist, sending a notice that the priority queue corresponding to the latest version of configuration information does not exist to the configuration server.
When receiving a notification that there is no priority queue corresponding to the latest version configuration information sent by the cache server, executing step 405; step 406 is performed when the first license returned by the cache server is received.
Specifically, in the configuration server, when configuration update occurs, a unique version number corresponding to the current version configuration information may be generated, and a priority queue establishment request may be sent to the cache server, where the request may include the version number and the generation time of the latest version configuration information, and when the cache server receives the priority queue establishment request including the version number, a priority queue having expiration time corresponding to the version number may be established, and a license in which a preset number of pieces of initial timestamp information are the generation time of the latest version configuration information is inserted into the priority queue. If the configuration server judges that the latest version configuration information higher than the current version configuration of the service program instance to be configured exists, a license acquisition request containing the version number of the latest configuration version can be sent to the cache server.
Meanwhile, because the priority queue has the priority queue expiration time, when the priority queue expiration time is reached, the priority queue can be deleted by the cache server, so that when a license acquisition request of the configuration server is received, the cache server can firstly judge whether the priority queue corresponding to the latest version configuration information exists at the current moment.
In this embodiment, a distributed cache manner may also be adopted to perform related operations on the priority queue and the licenses in the priority queue, that is: the number of the cache servers can be multiple, when the number of the licenses to be established is large, the total capacity of the cache servers can be improved in a distributed cache mode, and meanwhile, the priority queues and the license data can be backed up to prevent the problem of data loss caused by the fact that a certain cache server fails.
Step 405, when receiving a notification that the priority queue corresponding to the latest version configuration information does not exist and sent by the cache server, sending the latest version configuration information to the service program instance to be configured, so that the service program instance to be configured performs configuration update.
In a certain period of time, in each service program instance providing the same service function, there may be some instances that do not complete configuration updating, in order to avoid that the time for configuration inconsistency of each service program instance is too long, an expiration time may be set for the priority queue, and when the priority queue expires, the latest version configuration information may be sent to the service program instance to be configured, so that the service program instance to be configured performs configuration updating.
Step 406, when receiving the first license returned by the cache server, determining whether the current time is later than or equal to the timestamp information of the first license. If the current time is later than or equal to the timestamp information of the first license, executing step 407; if the current time is earlier than the timestamp information of the first license, go to step 409.
Step 407, sending the latest version configuration information to the service program instance to be configured, so as to perform configuration update on the service program instance to be configured.
Step 408, sending a first request for creating a new license to the cache server, so that the cache server creates a new second license corresponding to the latest version of configuration information in the priority queue, where the timestamp information of the second license is obtained by adding a preset time interval to the time when the latest version of configuration information is sent to the service program to be configured.
Step 409, sending a second new license request to the cache server license and stopping configuration updating, so that the cache server creates a new third license corresponding to the latest version configuration information in the priority queue, and the timestamp information of the third license is the timestamp information of the first license.
At this time, by introducing a priority queue corresponding to the latest version configuration information, it is determined whether the current time is later than or equal to the timestamp information of the first license, and then by setting timestamp information for the newly created license, centralized management of the license can be realized, thereby limiting the number of service instances that can be configured and updated within a preset time interval.
In the embodiment of the invention, the licenses are stored in the cache server in a centralized manner, so that when the total number of the licenses is large due to the large number of all service program instances providing the same service function or the large variety of the service function, the centralized management of the licenses can be facilitated. Meanwhile, when a configuration updating request sent by a service program instance to be configured in the business server is received, the configuration server does not directly send latest version configuration information to the service program instance to be configured, but extracts a first license, and when the current time is earlier than the timestamp information of the first license, the configuration updating of the service program instance to be configured and updated in a preset time interval is indicated to be reached, and at the moment, the configuration updating of the service program instance to be configured and updated which sends the configuration updating request is not performed, so that the situation that the service function is unavailable due to the fact that all service program instances which provide the same service function are simultaneously configured and updated in the preset time interval can be avoided, and the situation that the service function is unavailable can be reduced.
Referring to fig. 5, fig. 5 is a schematic flow chart of the configuration updating method applied to the cache server in the configuration system shown in fig. 3 according to the embodiment of the present invention, which includes the following specific steps:
step 501, a license acquisition request sent by a configuration server is received.
The license acquisition request is sent when the configuration server receives a configuration update request sent by a service program instance to be configured in the business server.
Step 502, extracting a first license from a preset number of licenses having timestamp information corresponding to the latest version configuration information.
The first license is the license with the earliest timestamp information in the preset number of licenses; presetting the generation time of the latest version configuration information of the initial timestamp information of the licenses; the preset number is less than the total number of instances of the service program to be configured. When the latest version information is obtained, the configuration server sends a request to the cache server, and the cache server generates and stores the preset number of licenses with the timestamp information corresponding to the latest version configuration information.
For example, in the configuration server, when a configuration update occurs, a unique version number corresponding to the current update may be generated, and a license establishment request may be sent to the cache server, where the request may include the version number, and when the cache server receives the license establishment request including the version number, a preset number of licenses having timestamp information corresponding to the version number may be established, further, the request may include generation time of the latest version configuration information, and the cache server may establish a priority queue with the version number as a key value, and insert a preset number of licenses having initial timestamp information as generation time of the latest version configuration information into the priority queue.
Step 503, sending the first license to the configuration server, so that the configuration server determines whether the current time is later than or equal to the timestamp information of the first license, if the current time is later than or equal to the timestamp information of the first license, sending the latest version of configuration information to the service program instance to be configured, so that the service program instance to be configured performs configuration update, and sends a first new license request to the cache server, and if the current time is earlier than the timestamp information of the first license, stopping configuration update, and sending a second new license request to the cache server.
Step 504, when receiving the first request for creating a new license sent by the configuration server, creating a new second license corresponding to the latest version of configuration information, where the timestamp information of the second license is the time when the latest version of configuration information is sent to the service program to be configured plus a preset time interval.
And step 505, when a second new license request sent by the configuration server is received, creating a new third license corresponding to the latest version of configuration information, wherein the timestamp information of the third license is the timestamp information of the first license.
In the embodiment of the present invention, after the first license is sent to the configuration server, when the configuration server determines that the current time is earlier than the timestamp information of the first license, it indicates that the number of service program instances requesting configuration update in the preset time interval has reached the preset number, and at this time, the configuration server does not perform configuration update on the service program instances to be configured that send the configuration update request, so that it is possible to avoid a situation that the service function is unavailable due to the fact that all service program instances providing the same service function perform configuration update simultaneously in the preset time interval, that is, the occurrence of a situation that the service function is unavailable can be reduced.
To embody the interaction flow among the devices in the configuration system shown in fig. 3, referring to fig. 6, fig. 6 is a specific example interaction flow diagram of a configuration updating method provided by an embodiment of the present invention, and the specific steps include:
step 601, the service program instance to be configured in the service server to be configured sends a configuration update request to the configuration server.
Specifically, the configuration update request may include information about the current version configuration of the service program instance to be configured, so that the configuration server may send the latest version configuration information higher than the current version configuration to the service program instance to be configured.
In step 602, the configuration server determines whether the latest version configuration information higher than the current version configuration of the service program instance to be configured exists. If the latest version configuration information higher than the current version configuration of the service program instance to be configured exists, step 603 is executed.
In step 603, the configuration server sends a license acquisition request for the latest version of configuration information to the cache server.
In step 604, the cache server determines whether a priority queue corresponding to the latest version configuration information exists at the current time. If there is no priority queue corresponding to the latest version of configuration information, go to step 605; if there is a priority queue corresponding to the latest version of configuration information, go to step 608.
In the configuration server, when configuration update occurs, a unique version number corresponding to the current version configuration information can be generated, a priority queue establishment request can be sent to the cache server, the request can contain the version number and the generation time of the latest version configuration information, when the cache server receives the priority queue establishment request containing the version number, a priority queue with expiration time corresponding to the version number can be established, and a preset number of licenses with initial timestamp information as the generation time of the latest version configuration information are inserted into the priority queue. If the configuration server judges that the latest version configuration information higher than the current version configuration of the service program instance to be configured exists, a license acquisition request containing the version number of the latest configuration version can be sent to the cache server.
Meanwhile, because the priority queue has the priority queue expiration time, when the priority queue expiration time is reached, the priority queue can be deleted by the cache server, so that when a license acquisition request of the configuration server is received, the cache server can firstly judge whether the priority queue corresponding to the latest version configuration information exists at the current moment.
In this embodiment, a distributed cache manner may also be adopted to perform related operations on the priority queue and the licenses in the priority queue, that is: the number of the cache servers can be multiple, when the number of the licenses to be established is large, the total capacity of the cache servers can be improved in a distributed cache mode, and meanwhile, the priority queues and the license data can be backed up to prevent the problem of data loss caused by the fact that a certain cache server fails.
In step 605, the cache server sends a notification to the configuration server that there is no priority queue corresponding to the latest version of configuration information.
In step 606, the configuration server sends the latest version configuration information to the service program to be configured.
Step 607, the service program to be configured is configured and updated.
Step 608, the cache server extracts the first license in the pre-established priority queue corresponding to the latest version of configuration information, and returns the first license to the configuration server.
In step 609, the configuration server determines whether the timestamp information is later than or equal to the first license. If the current time is later than or equal to the timestamp information of the first license, go to step 610; if the current time is earlier than the timestamp information of the first license, go to step 614.
Step 610, the configuration server sends the latest version configuration information to the service program instance to be configured.
Step 611, the service program to be configured instance performs configuration update.
Step 612, the configuration server sends a first request for a new license to the cache server.
Step 613, the cache server creates a new second license corresponding to the latest version configuration information in the priority queue, and the timestamp information of the second license is the time when the latest version configuration information is sent to the service program to be configured, plus a preset time interval.
Step 614, the configuration server sends a second new license request to the cache server and stops the configuration update.
Step 615, the cache server creates a new third license corresponding to the latest version configuration information in the priority queue, and the timestamp information of the third license is the timestamp information of the first license.
In the embodiment of the present invention, when receiving a configuration update request sent by a service program instance to be configured, a configuration server first extracts a first license, and determines whether the current time is later than or equal to timestamp information of the first license, and when the current time is earlier than the timestamp information of the first license, it indicates that the number of service program instances requesting configuration update in a preset time interval has reached a preset number, and at this time, does not perform configuration update on the service program instance to be configured that sends the configuration update request.
