Therefore, the target setting request is responded to; while when it is recognized that the issuing method of the target setting request is the method issued based on the client, since it is considered that the randomness of the setting content given by the target setting request may be relatively large and the risk is large, the response to the target setting request is refused. It can be seen that through this solution, the risk of the user setting the parameters of the in-memory database is reduced.

[0050] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art based on this application belong to the scope of protection of the present invention.

[0051] Since the so-called in-memory database refers to a database that caches the data to be accessed in memory. Deploying an in-memory database in any computing node can greatly improve the read and write speed of the computing node. Among them, exemplarily, the in-memory database may include a Redis (Remote Dictionary Server) database, a key-value database with in-memory high-speed caching.

[0052] Currently, in the use of in-memory databases, users can set the parameters of the in-memory database on the client side, so that the client generates and sends a parameter setting request, thereby performing relevant parameter settings on the in-memory database. For example, if a user needs to set the maximum value of the number of logs in the in-memory database to 1024, at this time, the user can enter the config set command on the client page: config set slowlog-max-len 1024. Correspondingly, the client can generate a setting request based on the config set command and send the setting request to the in-memory database in the computing node. Thus, the in-memory database responds to the setting request to set the maximum number of logs to be saved to 1024. Among them, the function of the client is not limited to this, and it is also used for read and write operations of the database.

[0053] However, since users may not be very clear about the relevant principles of various parameters, randomly setting relevant parameters by users on the client side may bring risks to the system. For example, in the above request for setting the maximum number of logs to be saved, if the user sets the number of logs to be saved too large, occupying too much storage space, it will affect the working efficiency of the in-memory database. However, if users are prohibited from setting the relevant parameters of the in-memory database, it cannot meet the usage requirements of users.

[0054] In order to reduce the risks generated when users set the parameters of the in-memory database, an embodiment of the present invention provides a method, device, and electronic device for setting database parameters.

[0055] First, a method for setting database parameters provided by an embodiment of the present invention will be introduced below.

[0056] Among them, a method for setting database parameters provided by an embodiment of the present invention is applied to the in-memory database of a computing node. Exemplarily, the in-memory database can be a Redis database, but of course it is not limited thereto.

[0057] Moreover, the computing node in this embodiment can be a node in the cloud for deploying the in-memory database. Of course, it can also be a node in the local area network for deploying the in-memory database. In addition, a computing node can correspond to a management node, and the management node can manage the computing node. For example, monitor the running status, resource usage, etc. of the computing node.

[0058] A method for setting database parameters provided by an embodiment of the present invention is applied to the in-memory database in a computing node; the method includes:

[0059] Receive a setting request for in-memory database parameters as a target setting request;

[0060] Identify the sending method of the target setting request; wherein, the sending method includes a first sending method based on the client corresponding to the in-memory database, and a second sending method based on a specified setting page. The specified setting page is a page provided by the management node corresponding to the computing node for the user and having guiding instructions for parameter setting.

[0061] If it is identified that the sending method of the target setting request is the second sending method, respond to the target setting request to set the in-memory database based on the setting content given in the target setting request;

[0062] If it is identified that the sending method of the target setting request is the first sending method, reject responding to the target setting request.

[0063] In the solution provided by the embodiment of the present invention, when the in-memory database identifies that the sending method of the target setting request is the method based on the specified setting page, since it is considered that the specified setting page has guiding instructions for parameter setting, the randomness of the setting content given in the target setting request is relatively low and the risk is small. Therefore, the target setting request is responded to; while when it is identified that the sending method of the target setting request is the method based on the client, since it is considered that the randomness of the setting content given in the target setting request may be relatively large and the risk is large, the target setting request is rejected from being responded to. It can be seen that through this solution, the risk when the user sets the parameters of the in-memory database is reduced.

[0064] The following introduces a method for setting database parameters provided by an embodiment of the present invention in conjunction with the accompanying drawings.

[0065] As Figure 1 shown, a method for setting database parameters provided by an embodiment of the present invention is applied to an in-memory cache in-memory database in a computing node; the method includes the following steps:

[0066] S101, receiving a setting request for database parameters as a target setting request;

[0067] Exemplarily, the setting content given by the target setting request includes: the maximum number of logs to be saved, debug error-checking instructions, saving the current data to disk, etc.

[0068] S102, identifying the sending method of the target setting request; wherein, the sending method includes a first sending method based on a client corresponding to the in-memory database, and a second sending method based on a specified setting page, and the specified setting page is a page provided by a management node corresponding to the computing node for users and having guiding instructions for parameter setting;

[0069] In this embodiment, an in-memory database in a computing node corresponds to a client, and users can perform read and write operations on the in-memory database through this client; moreover, this client can also provide an entry for setting database parameters, so that users can set parameters for the in-memory database. For example: users enter the config set command in the page of the client, and correspondingly, the client generates a setting request based on the config set command and sends it to the in-memory database in the computing node.

[0070] And, the management node can provide a specified setting page for users, and specifically, the specified setting page can be provided by a database service component or a database backend control platform pre-deployed in the management node. Through this specified setting page, users can set parameters for the in-memory database in the computing node; in this way, through the transfer of the setting request by the management node, the in-memory database in the computing node can respond to the setting request.

[0071] Based on the above description, it can be known that the target setting request can be sent to the in-memory database by adopting the first sending method: the sending method based on the client, that is, after users enter a setting command for database parameters in the client, the in-memory database receives the target setting request; and the target setting request received by the in-memory database can also be sent to the in-memory database by adopting the second sending method: the sending method based on the specified setting page, that is, after users perform parameter setting in the specified setting page, the in-memory database receives the target setting request.

[0072] When the target setting request is sent through the second sending method, since the setting command is directly input by the user through the client, the randomness of the setting content given by the target setting request is relatively large, and there are relatively high risks. When the target setting request is sent through the second sending method, since the user makes the settings based on the guiding instructions, the randomness is greatly reduced and the risks are also relatively low.

[0073] Therefore, in order to reduce the risks when the user sets the parameters of the in-memory database, after receiving the target setting request, the in-memory database does not directly respond to the target setting request. Instead, it identifies the sending method of the target setting request and performs different operations according to the identification result. It should be noted that in the management node of the server of the present invention, a specified setting page is provided for the user, and the interfaces of the parameters that can be set are placed in the specified setting page. The user directly sets the parameters in the specified setting page without writing the config set instruction, and thus can complete the configuration of the in-memory database parameter setting.

[0074] It should be noted that in order to prevent the risks that may be brought about by the user's random parameter setting, guiding instructions for parameter setting are preset in the specified setting page provided by the management node for the user. Exemplarily, the specified setting page displays configuration guiding information and / or risk description content of the database parameters. The configuration guiding information may be a risk-free configuration range and / or a risky configuration range, and the risk description content may be an indication of whether there is a risk and the specific risk content. The user refers to the configuration guiding content displayed in the specified setting page to set the parameters, so that the risks caused by the set parameters can be effectively avoided. In addition, when the parameters set by the user exceed the risk-free configuration range or are in the risky configuration range, the specified setting page can remind the user of the possible risks or directly reject the generation of the target setting request.

[0075] In addition, it can be understood that the above-mentioned first sending method based on the client corresponding to the in-memory database includes:

[0076] The method of sending any setting request from the client corresponding to the in-memory database to the in-memory database, where any setting request is the request sent by the client when detecting the user's setting operation for the database parameters. For the first sending method, the sender of any setting request is the client.

[0077] There are various above-mentioned second sending methods based on the specified setting page provided by the management node. Exemplarily, in one implementation, the second sending method based on the specified setting page provided by the management node may include: the method of sending any setting request from the management node to the in-memory database. In this implementation, the sender of any setting request is the management node.

[0078] In another implementation, the second sending method based on the specified setting page provided by the management node may include:

[0079] A method of sending any setting request from the proxy server to the in-memory database;

[0080] Wherein, the proxy server is located in the computing node, and any setting request is sent by the proxy server after receiving the initial request forwarded by the management node, and the initial request is a request for setting database parameters sent by the user based on the specified setting page.

[0081] In this implementation, the management node sends any setting request to the proxy server in the computing node, and then the proxy server forwards it to the in-memory database. Among them, the proxy server may also have the following functions: receiving other types of requests sent by the management node to the in-memory database, such as: database creation requests; and monitoring the running status of the in-memory database and reporting it to the management node, and so on.

[0082] There are various specific implementation methods for identifying the sending method of the target setting request. Exemplarily, in one implementation, it can be identified whether the target setting request carries a predetermined character, and the predetermined character is a character added by the management node when relaying the request. For the sake of clear layout and clear solution, the specific implementation method for identifying the sending method of the target setting request will be introduced in combination with other embodiments later.

[0083] S103, if it is identified that the sending method of the target setting request is the second sending method, respond to the target setting request to set the in-memory database based on the setting content given by the target setting request;

[0084] That is, it is identified that the target setting request comes from the specified setting page. The setting content is the content that can be set through the config set command. There are guiding instructions for parameter setting on the specified setting page. Responding to the target setting request from the specified setting page can effectively avoid risks when users set the setting parameters of the in-memory database.

[0085] S104, if it is identified that the sending method of the target setting request is the first sending method, reject responding to the target setting request.

[0086] That is, reject responding to the target setting request from the client.

[0087] In the solution provided by the embodiments of the present invention, when the in-memory database identifies that the issuing manner of the target setting request is the manner issued based on the specified setting page, since it is considered that the specified setting page has guiding instructions for parameter setting, the randomness of the setting content given by the target setting request is relatively low and the risk is relatively small. Therefore, the target setting request is responded to. When it is identified that the issuing manner of the target setting request is the manner issued based on the client, since it is considered that the randomness of the setting content given by the target setting request may be relatively large and the risk is relatively large, the response to the target setting request is refused. It can be seen that through this solution, the risk for users to set parameters of the in-memory database is reduced.

[0088] It can be understood that when the issuing party of any setting request is the client, that is, when any setting request is issued through the first issuing manner, the IP address of the issuing party of the setting request is the IP address of the user side. When any setting request is issued through the second issuing manner, since the transit operation of the management node is required, the issuing party of the setting request can be considered not to be the user side. Specifically: if the second issuing manner includes the manner of the management node issuing any setting request to the in-memory database, the issuing party of the setting request is the management node; if the second issuing manner includes the manner of the proxy server issuing any setting request to the in-memory database, the issuing party of the setting request is the proxy server.

[0089] It can be seen that when any setting request is sent through different issuing manners, the issuing party of the setting request is different, and the IP address is the identification information of the issuing party. Moreover, when the second issuing manner is adopted, the number of issuing parties is limited. Therefore, the IP address of the issuing party when the second issuing manner is adopted can be used as the basis for identifying the issuing manner of any setting request.

[0090] Based on this processing idea, optionally, in another embodiment of the present invention, the in-memory database pre-stores a whitelist of IP addresses, where the whitelist includes: the IP address of the issuing party of the setting request when sent through the second issuing manner;

[0091] The identifying the issuing manner of the target setting request includes:

[0092] Identifying whether the IP address of the issuing party of the target setting request is the IP address in the whitelist;

[0093] If so, determining that the issuing manner of the target setting request is the second issuing manner, otherwise, determining that the issuing manner of the target setting request is the first issuing manner.

[0094] In this embodiment, by setting the whitelist, the issuing manner of the target setting request can be quickly and effectively identified.

[0095] Moreover, if the second sending method includes: the method of sending any setting request from the management node to the in-memory database, then the sender of the setting request; correspondingly, the IP address of the management node is included in the whitelist.

[0096] If the second sending method includes: the method of sending any setting request from the proxy server to the in-memory database, then the sender of the setting request is the proxy server; correspondingly, since the proxy server is located in the computing node, the IP address of the computing node is included in the whitelist. In this way, there is no need to know the IP address of the management node in advance, nor to consider the number of management nodes, making the setting of the whitelist more convenient and fast.

[0097] In this embodiment, by identifying whether the IP address of the sender of the target setting request is the IP address in the whitelist, the sending method of the target setting request is identified. In this way, the sending method can be quickly and effectively identified, thereby improving the setting efficiency of the parameters of the in-memory database.

[0098] For the convenience of understanding the database parameter setting method of the present invention, the following is combined with Figure 2 for an exemplary introduction.

[0099] As Figure 2 shown, the user generates a parameter setting instruction for the in-memory database through the specified setting page as the initial setting request. If the user sets a parameter that may cause risks, the specified setting page reminds the user of the possible risks or directly refuses to generate the target setting request.

[0100] After that, the management node forwards the initial setting request to the proxy server, and then the proxy server sends a setting request to the in-memory database according to the initial setting request. The setting content of the target setting request is the same as that of the initial setting request. Since the IP address of the proxy server is the local IP address of the computing node, therefore, the local IP address is preset and stored in the whitelist of the in-memory database. When receiving the target setting request, the in-memory database can determine whether the sending method of the target setting request is: the method sent based on the specified setting page by judging whether the IP address of the source of the target setting request is the local IP. If so, the in-memory database is set according to the setting content given by the target setting request; if not, the target setting request is ignored, that is, the response to the target setting request is refused.

[0101] Through the solution provided by this embodiment, the risk of the user setting the parameters of the in-memory database can be reduced.

[0102] Corresponding to the above method embodiment, the embodiment of the present invention also provides a database parameter setting device, which is applied to the in-memory cache in-memory database in the computing node; as Figure 3As shown in the figure, the device includes:

[0103] A receiving module 310 that receives a setting request for database parameters as a target setting request;

[0104] An identification module 320 that identifies the sending method of the target setting request; wherein, the sending method includes a first sending method based on a client corresponding to the in-memory database, and a second sending method based on a specified setting page, and the specified setting page is a page provided by a management node corresponding to the computing node for a user and having guiding instructions for parameter setting;

[0105] A response module 330 that, if it identifies that the sending method of the target setting request is the second sending method, responds to the target setting request to set the in-memory database based on the setting content given in the target setting request;

[0106] A rejection module 340 that, if it identifies that the sending method of the target setting request is the first sending method, rejects responding to the target setting request.

[0107] Optionally, the in-memory database pre-stores a whitelist of IP addresses, where the whitelist includes: the IP address of the sender of any setting request when sending through the second sending method;

[0108] The identification module 320 is specifically configured to:

[0109] Identify whether the IP address of the sender of the target setting request is an IP address in the whitelist;

[0110] If so, determine that the sending method of the target setting request is the second sending method, otherwise, determine that the sending method of the target setting request is the first sending method.

[0111] Optionally, the second sending method based on the specified setting page provided by the management node includes:

[0112] A method of sending any setting request from an agent server to the in-memory database;

[0113] wherein, the agent server is located in the computing node, and any setting request is sent by the agent server after receiving an initial request forwarded by the management node, and the initial request is a request for setting database parameters sent by a user based on the specified setting page;

[0114] Correspondingly, the whitelist includes the local IP address of the computing node.

[0115] Optionally, the first sending method of the client corresponding to the in-memory database includes:
