[0030] To make the objectives, technical solutions, and advantages of this document clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this document.

[0031] The following will detail the technical solutions provided by each embodiment of the present application with reference to the drawings.

[0032] In a modern computer system, the configuration file of a database is used to store the parameters and settings of the database. The configuration file usually contains various configuration options and parameters to ensure the correct operation of the database. Due to changes in the configuration during the operation of the database, it is necessary to update the configuration file in a timely manner to maintain the consistency between the configuration file and the actual configuration of the database. If the operation and maintenance engineer adjusts the configuration of the database but does not modify the configuration file read when the database is started, it will cause the configuration modified online to be reset by the content in the configuration file after the database is restarted, resulting in the invalidation of the online modified configuration.

[0033] For the above reasons, the method for updating a configuration file provided by the embodiments of the present application is executed by a computer device as the execution subject, for example, by at least one of devices such as a server, a laptop, a desktop computer, a tablet computer, or an intelligent robot.

[0034] Figure 1 It is a schematic structural diagram of a computer system provided by one or more embodiments of the present application, and the computer system includes a terminal 120 and a server 140.

[0035] The terminal 120 and the server 140 are interconnected through a wired or wireless network.

[0036] The terminal 120 may include at least one of a smart phone, a laptop computer, a desktop computer, a tablet computer, a smart speaker, and a smart robot.

[0037] The terminal 120 includes a display.

[0038] The terminal 120 includes a first memory and a first processor. A first program is stored in the first memory, and the first program is called and executed by the first processor to implement the configuration file update method provided by the present disclosure. Optionally, the first processor may be used to implement the configuration file update method provided by the present disclosure.

[0039] The server 140 includes a second memory and a second processor. A second program is stored in the second memory, and the second program is called by the second processor to implement the configuration file update method provided by the present disclosure.

[0040] The server may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms. The terminal may be a smart phone, a tablet computer, a laptop computer, a desktop computer, a smart speaker, a smart watch, etc., but is not limited thereto. The terminal and the server may be directly or indirectly connected through wired or wireless communication means, and the present disclosure does not limit this.

[0041] For ease of description, in the following, the execution entity of the method is an electronic device capable of executing the configuration file update method. Specifically, the electronic device may be an electronic device such as a server, a laptop computer, a desktop computer, a tablet computer, or a smart robot, such as Figure 1 the terminal or server shown, to introduce the implementation manner of the method. It can be understood that the execution entity of the method being an electronic device is only an exemplary description and should not be construed as a limitation of the method.

[0042] Figure 2 is a schematic flowchart of the implementation of a configuration file update method provided by one or more embodiments of the present application, including:

[0043] S10, obtain the configuration information of the target database at specified intervals.

[0044] Among them, the configuration information of the target database includes at least one of the port number information of the target database, memory configuration information, database read-only status information, and I / O (input / output) parameter information. Of course, it should be understood that the configuration information refers to the currently effective configuration information of the target database.

[0045] Obtain the configuration information of the target database at specified intervals, that is, the system regularly or at a preset time interval obtains the configuration information of the target database. To avoid excessive consumption of system resources, the configuration information of the target database can be obtained once every certain period, for example, 5 minutes, 1 hour, 3 hours, and so on. The specific time interval is not limited.

[0046] Exemplarily, it can be achieved by establishing a connection with the target database and sending a request. The target database can be any type of database, such as a relational database, a NoSQL database, or other types of data storage.

[0047] S20, determine whether the configuration information of the target database has changed.

[0048] When the configuration information of the target database is obtained, the system will parse and analyze the configuration information of the target database to determine whether the configuration options and parameters therein have changed.

[0049] In this step, the configuration information of the target database can be compared with the information stored in the current configuration file to detect whether the configuration information of the target database has changed. If the configuration information of the target database is inconsistent with the current configuration file, the configuration information of the target database has changed.

[0050] S30, when the configuration information of the target database has changed, update the changed configuration information to the current configuration file to obtain an updated configuration file.

[0051] Among them, the configuration file of the target database is used to store the parameters and settings of the target database; the configuration file usually contains various configuration options and parameters to ensure the correct operation of the target database.

[0052] It should be understood that if the configuration information of the target database has changed, the current configuration file will be updated at this time to reflect the latest configuration information of the target database in the current configuration file.

[0053] To better understand the implementation manner of the embodiments of the present application, an embodiment is provided below:

[0054] Assume that the target database is a database of an e-commerce website, which stores configuration information of commodity prices. The system obtains the configuration information of the target database every three hours and compares the configuration information with the information in the current configuration file. After obtaining the configuration of the target database, if it is found that the price of a commodity in the target database has changed, the system will update the new commodity price to the configuration file by updating the corresponding configuration options and parameters in the current configuration file.

[0055] It can be seen that the configuration file updating method of the embodiment of the present application can realize the automatic update of the target database configuration file, and provides a convenient and accurate way to maintain the consistency between the configuration file and the running configuration.

[0056] The technical solution of the embodiment of the present application is described in detail below. Figure 3 , Figure 3 This is a schematic diagram of an implementation flow of another configuration file update method provided by one or more embodiments of the present application, including:

[0057] Step S302: Obtain configuration information of the target database at specified intervals.

[0058] In this step, the specific implementation method of obtaining the configuration information of the target database at specified intervals is consistent with that in step S10. For details, please refer to the description in step S10, which will not be repeated here.

[0059] Step S304, traverse the configuration information of the target database to determine whether the configuration information of the target database has been changed.

[0060] After obtaining the configuration information of the target database, the configuration information of the target database can be parsed and analyzed to determine the configuration options and parameters therein. Then, the configuration information of the target database is traversed and compared with the configuration information stored in the current configuration file to detect whether the configuration information of the target database has changed.

[0061] If the configuration information of the target database is inconsistent with the current configuration file, it means that the configuration information of the target database has been changed, and step S306 is executed; if the configuration information of the target database is consistent with the current configuration file, it means that the configuration information of the target database has not been changed, and step S301 is executed.

[0062] Step S306, reading the current configuration file of the target database.

[0063] Step S308, determining whether the configuration information of the target database has been updated in the current configuration file.

[0064] It is determined whether the configuration information of the target database has been updated in the current configuration file. If the configuration information of the target database has not been updated in the current configuration file, step S310 is executed; if the configuration information of the target database has been updated in the current configuration file, step S301 is executed.

[0065] Step S310, back up the current configuration file.

[0066] In actual applications, the current configuration file can be backed up according to certain rules. For example, the current system time (including year, month, day, hour, minute, second, etc.) can be added to the name of the current configuration file to form the name after the backup. Of course, the specific backup rules can be configured according to the actual situation.

[0067] Step S312: Update the configuration information of the target database in the current configuration file.

[0068] In order to better understand the implementation of the embodiments of the present application, an embodiment is provided below:

[0069] Assume that the target database is a relational database (of course, it can also be a NOSQL database or other type of database), which stores port number information, memory configuration information, database read-only status information, I / O parameter information, etc. At this time, the configuration information of the target database can be obtained every 3 hours, and the configuration information can be compared with the current configuration file. If the port number information of the target database is found to have changed after obtaining the configuration information, the current configuration file will be backed up, and the updated port number information will be updated in the current configuration file to update the configuration file.

[0070] It can be seen that the configuration file updating method of the embodiment of the present application can automatically detect the configuration changes of the target database and update the configuration file after the configuration changes to maintain the consistency between the configuration file and the actual configuration.

[0071] It should be understood that this method has the advantages of being simple and accurate, and can be widely used in various scenarios where it is necessary to maintain consistency between the configuration file and the actual configuration.

[0072] Optionally, in one implementation, after performing the above step S30, the method further includes:

[0073] Record changes to the target database's configuration information;

[0074] A prompt message is sent to the operation and maintenance end of the target database; the prompt message includes information that the configuration information of the target database has been changed.

[0075] It should be understood that the operation and maintenance terminal in the embodiments of the present application generally refers to the personnel responsible for the maintenance of the target database, including but not limited to operation and maintenance engineers. By recording the information of the configuration information change of the target database and sending the corresponding prompt information to the operation and maintenance terminal, the operation and maintenance terminal can timely understand the configuration change situation of the target database, and then record and file the changes of the target database.

[0081] Traverse the configuration information of the target database, and compare the configuration information of the target database with the information in the current configuration file;
