It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein.

Example 1
Fig. 1A is a flowchart of a dynamic loading method of configuration information according to an embodiment of the present invention, where the embodiment is applicable to a case of dynamically updating configuration information of each component in a load balancing server, and the method may be performed by a dynamic loading device of configuration information, where the dynamic loading device of configuration information may be implemented in a form of hardware and/or software, and the dynamic loading device of configuration information may be configured in an electronic device, and typically, the electronic device may be a load balancing server. As shown in fig. 1A, the method includes:
s110, when the updating configuration information is received, a target component corresponding to the updating configuration information is obtained.
In this embodiment, the update configuration information issued by the software defined network controller (Software Defined Network Controller, SDNC) may be received by a pre-deployed configuration information receiving module, such as an application program interface (Application Programming Interface, API).
When the SDNC issues the update configuration information to the load balancing server, the SDNC may issue corresponding update configuration information for different components respectively; further, corresponding update configuration information can be issued for different functional modules of the component. In the present embodiment, the data structure of updating the configuration information may not be particularly limited.
The target component may include a load balancer nminx and/or a keep-alive module keep-alive, among others. The load balancer can comprise a monitor, a health check module, a certificate module, a back-end server group module, a back-end server module, a forwarding rule module and other functional modules.
In a specific example, after the update configuration information is received through the API interface, content analysis may be performed on the update configuration information based on a preset communication protocol, and a component identifier corresponding to the current update configuration information may be obtained from a content analysis result, so as to determine the target component.
And S120, if the updated configuration information passes the conflict verification successfully, writing the updated configuration information into a preset database, and issuing a configuration change message on a target channel of the preset database.
Specifically, after the updated configuration information is successfully received, whether the new configuration corresponding to the updated configuration information conflicts with the original configuration or not may be determined based on a preset conflict detection rule, for example, whether there is repeated allocation of an interface, the configuration buffer exceeds the maximum buffer, and so on. If no conflict exists, the current update configuration information is determined to pass the conflict verification successfully, and the update configuration information can be stored in a preset database. If the conflict is detected, the updated configuration information can be directly discarded, and an abnormal alarm is carried out.
The preset database may be a key value type database, for example, a dis database. In this embodiment, when the updated configuration information is written into the preset database, the updated configuration information may be used to replace and store the current configuration information corresponding to the target component; alternatively, the updated configuration information and the current configuration information may be simultaneously maintained, and different version identifiers may be used to distinguish the updated configuration information from the current configuration information.
Specifically, when the updated configuration information is stored, a mapping relationship between the component identifier corresponding to the target component and the updated configuration information may be established, and the mapping relationship is stored in a preset database. Secondly, the preset database can also support searching of matching configuration information based on the component identification.
Further, after the storing of the updated configuration information is successfully completed, the preset database may send configuration change information to the target channel based on the subscription and publishing function, so as to notify the subscriber of the channel that the configuration information of the target component has been changed. The configuration change information may include a component identifier, an information change identifier, and the like. In this embodiment, the target channel of the Redis database may be subscribed in advance by the configuration information receiving module, and the channel message may be monitored in real time by a preset dedicated process.
S130, when the configuration change message is successfully monitored in the target channel, reading the updated configuration information from the preset database, and reloading the updated configuration information through the target component to realize configuration updating of the target component.
Specifically, when the configuration information receiving module monitors the configuration change message corresponding to the target component in the target channel, the updated configuration information can be read from the preset database based on the component identifier corresponding to the target component. Then, the updated configuration information can be automatically loaded through a preset configuration loading script program in the target component, and corresponding configuration change is carried out, so that the configuration update of the target component is realized; alternatively, the configuration update may be implemented by first generating an update configuration file from the update configuration information and automatically loading the update configuration file.
In this embodiment, by adopting the configuration information receiving module to receive, write and read the configuration information and adopting the subscription and publishing functions of the preset database, the operation decoupling of configuration receiving and configuration issuing is successfully realized, so that when a plurality of worker processes are present to update the configuration, each process can successfully acquire updated configuration information, and the consistency of each process can be ensured.
According to the technical scheme, when the updated configuration information is received, the target component corresponding to the updated configuration information is obtained; if the updated configuration information passes the conflict verification successfully, writing the updated configuration information into a preset database, and issuing a configuration change message on a target channel of the preset database; when the configuration change message is successfully monitored in the target channel, reading updated configuration information from a preset database, and reloading the updated configuration information through the target component to realize the configuration update of the target component; by adopting a preset database to store configuration information for a long time and decoupling configuration receiving and configuration issuing operations, dynamic loading of the configuration information of the load equalizer can be realized, the loss of the configuration information caused by memory failure can be avoided, and concurrent operation of configuration updating can be supported.
In an optional implementation manner of this embodiment, the updating the configuration information successfully passes the conflict verification may include:
and reading the current configuration information corresponding to the target component from the preset database, and if the preset conflict detection condition is not met between the updated configuration information and the current configuration information, determining that the updated configuration information passes the conflict verification successfully.
The current configuration information may be configuration information currently used by the target component. The preset conflict detection condition may be preset condition information for judging whether there is a configuration conflict between the two configuration information, for example, at least one preset conflict rule may be satisfied between the updated configuration information and the current configuration information.
In this embodiment, when performing conflict verification, the current configuration information corresponding to the target component may be read from a preset database according to the component identifier corresponding to the target component; then, whether the preset conflict detection condition is met between the updated configuration information and the current configuration information is judged. If the preset conflict detection condition is detected to be met, the existence of configuration conflict can be determined, and the updated configuration information can be directly discarded. If the detection result does not meet the preset conflict detection condition, the success of the conflict verification can be determined, and the updated configuration information can be further stored in a preset database.
In another optional implementation manner of this embodiment, writing the update configuration information into a preset database may include:
judging whether the updated configuration information is the same as the current configuration information;
If not, replacing and storing the current configuration information in the preset database by adopting the updated configuration information.
Specifically, when the updated configuration information is stored in the preset database, the updated configuration information and the current configuration information may be compared item by item, so as to determine whether the updated configuration information and the current configuration information are the same. When the content of the update configuration information and the content of the update configuration information are detected to be identical, the exception of the update configuration information currently issued by the SDNC can be determined, the update configuration information can be selected to be directly discarded, the original current configuration information is still reserved, and subsequent configuration information reloading operation is not needed. When the two contents are detected to be different, the current configuration information can be deleted from the preset database, and the updated configuration information is stored to the position of the current configuration information, so that the replacement storage of the current configuration information is realized.
In another optional implementation manner of this embodiment, after reloading the update configuration information by the keep-alive module to implement configuration update of the keep-alive module, the method may further include:
detecting the running state of a current load equalizer through a current keep-alive module;
if the running state of the current load balancer is detected to be abnormal, the current load balancer is closed, and a preset virtual internet protocol address is distributed to the standby load balancer of the standby load balancing server, so that high availability of load balancing is ensured.
In a specific example, the structure of the load balancing system to which the dynamic loading method of configuration information is applied may be as shown in fig. 1B. The load balancing system may be composed of a main load balancing server 01 (main node) and a standby load balancing server 02 (standby node), each load balancing server includes an information receiving module Agent, a Redis database, a load balancing nminx and a keep-alive module keepalive, and communication connection exists between the keep-alive modules in different load balancing servers.
The Agent is configured to provide a related Rest API interface, to receive configuration information issued by the SDNC, and store the configuration information to the Redis database after checking the configuration information is completed, and when a configuration change message is monitored from a subscribed Redis channel, read the configuration information from the Redis database, and send the configuration information to the nginnx or keepalive. The Redis database is used for supporting writing and reading of configuration information, and after successful storage, configuration change information is sent to a designated channel based on subscription and release functions.
The nmginx is used to reload configuration information to complete configuration updates and to provide load balancing among hosts based on the configuration information. Keepalive is used to provide high availability for nminix. Specifically, keepalive can detect the running state of the corresponding nmginx in real time by periodically sending a heartbeat command or the like. Each ng inx has the same configuration information and can synchronously perform configuration update.
In a load balancing system, each Nginx shares a preset virtual internet protocol address (Virtual Internet Protocol, VIP), and service requests can be allocated to the appropriate Nginx by allocating VIP. Under normal conditions, the virtual internet protocol address is used by the nmginx of the master node, and when the nmginx of the master node is abnormal, for example, is down, has no reply to a heartbeat instruction, and the like, the keep alive drifts the VIP to the standby node, at the moment, the nmginx of the standby node uses the VIP to continue to provide services for users, the users have no perception in the process, and the service is not interrupted, so that the high availability of the load balancing service is ensured.
Example two
Fig. 2A is a flowchart of a dynamic loading method of configuration information according to a second embodiment of the present invention, where the technical solution in this embodiment may be combined with one or more of the foregoing embodiments. As shown in fig. 2A, the method includes:
s210, when update configuration information is received, a target component corresponding to the update configuration information is obtained.
S220, reading current configuration information corresponding to the target component from a preset database, and if the preset conflict detection condition is not met between the updated configuration information and the current configuration information, determining that the updated configuration information passes the conflict verification successfully.
And S230, if the updated configuration information is determined to be different from the current configuration information, replacing and storing the current configuration information by adopting the updated configuration information in the preset database, and issuing a configuration change message on a target channel of the preset database.

S250, generating an update configuration file according to the update configuration information and a preset file generation rule, and reloading the update configuration file through the target component to realize configuration update of the target component.
The preset file generation rule may be a grammar rule of a preset configuration file, for example, the configuration file is composed of instructions and instruction blocks, each instruction ends with a semicolon, and the space between the instructions and the parameters is divided by space symbols. Optionally, for different types of components, a general file generation rule may be preset, or a file generation rule corresponding to each may be preset, for example, a preset nminix file generation rule, a preset keepalive file generation rule, and the like.
In this embodiment, after the configuration information receiving module reads the update configuration information from the preset database, the configuration information receiving module may convert the current update configuration information into a corresponding update configuration file according to a preset file generation rule. Then, a preset configuration loading script program in the target component can be executed to directly perform configuration updating according to the updating configuration file; or, the update configuration file may be stored under the configuration file directory of the target component, and a preset script is executed to automatically read the update configuration file, and change the configuration information according to the update configuration file.
Optionally, generating the update configuration file according to the update configuration information and the preset file generation rule may include: and acquiring a target file generation rule corresponding to the target component, and generating an update configuration file corresponding to the target component according to the update configuration information and the target file generation rule.
In the embodiment, by performing persistent storage on the configuration information and decoupling configuration receiving and issuing operations, flexible configuration on the Nginx configuration information is realized, complicated operation and maintenance operations are avoided, and the Nginx configuration information can continue to work according to the original configuration parameters even if the Nginx is down and restarted; secondly, the user-unaware configuration issuing is realized, the dynamic loading of configuration information can be realized without restarting by Nginx, and the continuity of load balancing service is ensured.
According to the technical scheme, if the preset conflict detection condition is not met between the updated configuration information and the current configuration information, the updated configuration information is determined to pass the conflict verification successfully; if the updated configuration information is determined to be different from the current configuration information, replacing and storing the current configuration information by adopting the updated configuration information in a preset database; secondly, after the update configuration information is read from a preset database, generating an update configuration file according to the update configuration information and a preset file generation rule, and reloading the update configuration file through a target component to realize configuration update of the target component; by carrying out conflict check and same check on the updated configuration information in advance, system errors caused by configuration information conflict setting can be avoided, and invalid update of the configuration information can be avoided; in addition, by generating the update configuration file corresponding to the update configuration information, the update configuration information can be locally stored, when the target component is restarted due to failure, the updated configuration information can be directly loaded from the local, and the configuration loading efficiency of the component during restarting can be improved.
In an optional implementation manner of this embodiment, reloading the update configuration file through the target component to implement configuration update of the target component may include:
Acquiring a configuration file path corresponding to the target component;

and reloading the updated configuration file under the configuration file path through the target component to realize configuration updating of the target component.
The configuration file path can be an access path matched with the configuration file corresponding to the target component; in this embodiment, according to the installation position of the target component in the load balancing server, the corresponding configuration file path of the target component may be automatically determined, for example, a file path corresponding to a file with a preset file name under the installation folder; or after the installation of the target component is completed, the corresponding configuration file path can be stored in a preset database, so that the configuration file path corresponding to the target component can be searched and obtained from the preset database according to the component identifier corresponding to the target component.
In a specific example, after determining the configuration file path corresponding to the target component, the original current configuration file in the configuration file path may be deleted, and the update configuration file may be stored in the configuration file path, so as to implement replacement and update of the configuration file. Finally, a preset configuration loading script program in the target component can be executed to automatically read the update configuration file under the path, thereby realizing configuration update of the target component.
In a specific implementation manner of this embodiment, a flow of a dynamic loading method of configuration information may be shown in fig. 2B. Firstly, receiving update configuration information issued by SDNC through Agent, and performing configuration conflict verification on the update configuration information; when the updated configuration information is detected to pass the configuration conflict verification, the updated configuration information is stored in a Redis database, and a configuration change message is issued to a preset channel by the Redis database.
Then, when the Agent successfully monitors the configuration change message in the channel, the Agent can read the updated configuration information from the Redis database and determine the component corresponding to the updated configuration information. When the component is Nginx, generating an Nginx configuration file according to the updated configuration information and a file generation rule corresponding to the Nginx; or when the component is determined to be keepalive, the keepalive configuration file can be generated according to the updated configuration information and the file generation rule corresponding to the keepalive.
Finally, a preset configuration file loading script can be executed to reload the nmginx configuration file or the keepalive configuration file generated by the reload, so as to realize the dynamic loading of the configuration information.
