[0032] When deploying multiple databases of different types, it is usually necessary to access the deployment platform of each database separately and manually deploy the database cluster. In addition, since the deployment process is not intuitive and clear enough, deploying the database cluster requires a lot of manpower and has low deployment efficiency.

[0033] An embodiment of the present disclosure provides a database cluster deployment method, including: in response to receiving a deployment requirement input by a user, determining a deployment process in a deployment process library that matches the deployment requirement as an initial deployment process, wherein the deployment requirement includes at least the deployment scale, deployment scenario, and deployment database type of the database cluster, and the initial deployment process includes multiple initial deployment steps; based on the user's selection operation for the multiple initial deployment steps, determining the initial deployment step selected by the user as a target deployment step; combining the target deployment step and the initial deployment steps in the multiple initial deployment steps that have a dependency relationship with the target deployment step to obtain a target deployment process; and deploying the database cluster according to the target deployment process.

[0034] The embodiments of the present disclosure obtain an initial deployment process by matching according to the deployment requirements of the user, and determine the target deployment process according to the user's selection operation for the initial deployment step, so that the user can intuitively understand the deployment process, and the obtained target deployment process can meet the user's deployment requirements. In addition, by considering the dependency between deployment steps in the process of generating the target deployment process, deployment failure can be avoided, and deployment efficiency can be further improved.

[0035] Figure 1 The application scenario diagram of the database cluster deployment method, apparatus, device, medium and program product according to the embodiments of the present disclosure is schematically shown.

[0036] like Figure 1 As shown, the application scenario 100 according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, a database cluster deployment server 105, and a database cluster 106. The network 104 is used as a medium for providing a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103 and the database cluster deployment server 105, and between the database cluster deployment server 105 and the database cluster 106. The network 104 may include various connection types, such as wired, wireless communication links or optical fiber cables, etc.

[0037] The user can use the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the database cluster deployment server 105 through the network 104 to receive or send messages, etc. Various communication client applications can be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only for example).

[0038] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0039] The database cluster deployment server 105 may be a server that provides database cluster deployment services, such as a background management server (only as an example) that provides support for the database cluster deployment platform browsed by the user using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received user request and other data, and feed back the processing results (such as web pages, information, or data obtained or generated according to the user request) to the terminal device.

[0040] The database cluster 106 may include a first database node 106_1 and a second database node 106_2. The first database node 106_1 and the second database node 106_2 may be deployed on the same server or on different servers.

[0041] The user can access the database cluster deployment platform on the first terminal device 101, the second terminal device 102, and the third terminal device 103, and interact with the database cluster deployment server 105 through the network 104 to generate a target deployment process. The database cluster deployment server 105 deploys the database cluster 106 according to the target deployment process. Specifically, in the process of deploying the database cluster 106, the first database node 106_1 and the second database node 106_2 can be configured respectively.

[0042] It should be noted that the database cluster deployment method provided in the embodiment of the present disclosure can generally be executed by the database cluster deployment server 105. Accordingly, the database cluster deployment device provided in the embodiment of the present disclosure can generally be set in the database cluster deployment server 105. The database cluster deployment method provided in the embodiment of the present disclosure can also be executed by a server or server cluster that is different from the database cluster deployment server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103, the database cluster 106 and / or the database cluster deployment server 105. Correspondingly, the database cluster deployment device provided in the embodiment of the present disclosure can also be set in a server or server cluster that is different from the database cluster deployment server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103, the database cluster 106 and / or the database cluster deployment server 105.

[0043] It should be understood that Figure 1The number of terminal devices, networks and servers in the embodiment is only for illustration. According to the implementation requirements, there may be any number of terminal devices, networks, database cluster deployment servers and database nodes.

[0044] The following will be based on Figure 1 The scene described by Figure 2~Figure 5 The database cluster deployment method of the disclosed embodiment is described in detail.

[0045] Figure 2 The flowchart of the database cluster deployment method according to the embodiment of the present disclosure is schematically shown.

[0046] like Figure 2 As shown, the database cluster deployment method of this embodiment includes operations S210 to S240.

[0047] In operation S210 , in response to receiving a deployment requirement input by a user, a deployment process matching the deployment requirement in a deployment process library is determined as an initial deployment process.

[0048] According to an embodiment of the present disclosure, the deployment requirements include at least the deployment scale, deployment scenario, and deployment database type of the database cluster, and may also include the application scenario of the database cluster, etc. Specifically, the deployment scale may include information such as the number of database nodes in the database cluster, the deployment scenario may include a cloud deployment scenario or a local deployment scenario, etc., and the deployment database type may characterize the type of database used by the database cluster.

[0049] According to an embodiment of the present disclosure, a user may input deployment requirements through a requirements interface. Specifically, when inputting deployment requirements in the requirements interface, the input method may be text input or input through a drop-down box.

[0050] According to an embodiment of the present disclosure, a deployment process library may store multiple deployment processes to meet different deployment requirements. One deployment process may correspond to multiple deployment requirements, and one deployment requirement may correspond to multiple deployment processes.

[0051] According to an embodiment of the present disclosure, when determining an initial deployment process, deployment requirements may be used to perform matching in a deployment process library, and a deployment process with a high degree of matching with the deployment requirements may be determined as the initial deployment process.

[0052] According to an embodiment of the present disclosure, the initial deployment process includes multiple initial deployment steps, and may also include a sequence and logical relationship between the multiple initial deployment steps.

[0053] In operation S220, according to the user's selection operation on the plurality of initial deployment steps, the initial deployment step selected by the user is determined as the target deployment step.

[0054] According to an embodiment of the present disclosure, there are multiple initial deployment steps in the initial deployment process, but there may be initial deployment steps that the user does not need among the multiple initial deployment steps. Therefore, the user can select the multiple initial deployment steps and choose the target deployment step that is actually needed from the multiple initial deployment steps.

[0055] According to an embodiment of the present disclosure, the initial deployment step may also have execution information, and the execution information may be used to specify the execution method of the initial deployment step. For example, when the initial deployment step is to install a deployment package, the execution information of the installation deployment package may be used to specify the deployment package version and installation location when installing the deployment package.

[0056] According to an embodiment of the present disclosure, the user can also perform an execution information modification operation on the initial deployment step to adjust the execution mode of the initial deployment step. Specifically, the user can select execution information that meets the requirements from multiple predetermined execution information of the initial deployment step. For example, when the initial deployment step is to install a deployment package, the execution information specifies the installation of the first version of the deployment package. At this time, the user can specify the installation of the second version of the deployment package by modifying the execution information.

[0057] According to an embodiment of the present disclosure, the user may also add deployment steps not included in the initial deployment process, that is, add other deployment steps in addition to the multiple initial deployment steps.

[0058] In operation S230, the target deployment step and the initial deployment steps having a dependency relationship with the target deployment step among the multiple initial deployment steps are combined to obtain a target deployment process.

[0059] According to an embodiment of the present disclosure, since there may be dependencies between deployment steps, for example, the deployment step of installing the deployment package depends on the deployment step of downloading the deployment package, and the user may not consider the dependencies between the deployment steps when selecting multiple initial deployment steps, it is possible to combine the target deployment step and the initial deployment step that has a dependency on the target deployment step to avoid the deployment process consisting of multiple target deployment steps from failing to execute normally.

[0060] According to the embodiments of the present disclosure, the dependency relationship between deployment steps can be preconfigured. After the user performs a selection operation, the initial deployment step that the target deployment step depends on can be determined based on the target deployment step selected by the user and using the dependency relationship of the target deployment step.

[0061] In operation S240 , a database cluster is deployed according to the target deployment process.

[0062] According to an embodiment of the present disclosure, when a database cluster is deployed according to a target deployment process, a script file capable of implementing the target deployment process may be executed to deploy the database cluster.

[0063] According to the embodiments of the present disclosure, by matching according to the deployment requirements of the user, an initial deployment process is obtained, and the target deployment process is determined according to the user's selection operation for the initial deployment step, so that the user can not only intuitively understand the deployment process, but also obtain the target deployment process that meets the user's deployment requirements, thereby improving the deployment efficiency. In addition, by considering the dependency between the deployment steps in the process of generating the target deployment process, the deployment failure caused by the lack of the deployment steps that the target deployment process depends on can be avoided, further improving the deployment efficiency.

[0064] According to an embodiment of the present disclosure, a database cluster is deployed according to a target deployment process, including: displaying a parameter configuration interface corresponding to the target deployment process; generating a target deployment process instance according to the target deployment process and configuration parameters input by a user in the parameter configuration interface; and executing the target deployment process instance to deploy the database cluster.

[0065] According to an embodiment of the present disclosure, the parameter configuration interface can be used to configure configuration parameters corresponding to the target deployment process. Specifically, since different deployment processes require different configuration parameters, after determining the target deployment process, the parameter configuration interface can be generated according to the configuration parameters required by the target deployment process.

[0066] According to an embodiment of the present disclosure, the configuration parameters include sub-configuration parameters for at least one database node in the database cluster. Specifically, the sub-configuration parameters may include information such as the address of the server where the database node is located, the database name, the cluster name, the cluster version, the user ID, and the password. The user may enter the configuration parameters in the parameter configuration interface by text input or drop-down box input.

[0067] According to the embodiments of the present disclosure, the target deployment process instance can represent a specific instance actually running according to the setting of the target deployment process. Specifically, the target deployment process can be instantiated into the target deployment process instance by using a workflow engine according to configuration parameters.

[0068] According to an embodiment of the present disclosure, after the target deployment process instance is successfully executed, if the deployed database cluster does not meet user requirements, the user can use the one-key destruction function to destroy the deployed database cluster.

[0069] According to an embodiment of the present disclosure, the target deployment process is instantiated according to the configuration parameters input by the user to obtain a target deployment process instance, and the automatic deployment of the database cluster is achieved by executing the target deployment process instance, eliminating the need for manual deployment of the database cluster and improving deployment efficiency.

[0070] Figure 3 A schematic diagram of generating a target deployment process instance according to an embodiment of the present disclosure is schematically shown.

[0071] like Figure 3 As shown, the deployment process library 310 stores multiple deployment processes, such as deployment process 1, deployment process 2, ..., deployment process n. An initial deployment process 320 matching the user's needs can be determined from the multiple deployment processes in the deployment process library 310, and a target deployment process 330 is determined according to the user's selection operation on the initial deployment process 320. A target deployment process instance 350 is generated according to the target deployment process 330 and the configuration parameters 340 input by the user.

[0072] According to an embodiment of the present disclosure, a target deployment process instance is generated according to the target deployment process and the configuration parameters input by the user in the parameter configuration interface, including: obtaining an initial script file corresponding to each deployment step in the target deployment process; generating a target script file according to the initial script file and the configuration parameters input by the user in the parameter configuration interface; and generating a target deployment process instance according to the target script file and the target deployment process.

[0073] According to an embodiment of the present disclosure, the initial script file may be a script file for implementing the deployment steps, and the initial script file does not include configuration parameters. Specifically, the initial script file may be a shell script, the initial script file may be a one-to-one correspondence between the deployment steps and the initial script file, and the initial script file may be pre-written and stored in the database cluster deployment platform.

[0074] According to an embodiment of the present disclosure, a correspondence table between deployment steps and script files may be used to determine the script file corresponding to the deployment step. Specifically, the correspondence table may include a script identifier of the script file.

[0075] According to an embodiment of the present disclosure, when acquiring an initial script file, the initial script file may be acquired from the storage location of the script file using a script identifier of the script file corresponding to the deployment step.

[0076] According to an embodiment of the present disclosure, the configuration parameter has a parameter identifier. When generating a target script file, the configuration parameter input by the user can be transferred to the initial script file according to the parameter identifier to obtain the target script file.

[0077] According to an embodiment of the present disclosure, the execution order between multiple target script files can be arranged according to the target deployment process, thereby obtaining a target deployment process instance.

[0078] According to an embodiment of the present disclosure, the configuration parameters input by the user are passed to the initial script file to obtain a target script file, and the target script file is used to implement automated deployment operations, thereby improving deployment efficiency.

[0079] According to an embodiment of the present disclosure, a target deployment process instance is executed to facilitate deployment of a database cluster, including: sending a deployment file corresponding to the target deployment process instance to a server where a database node is located according to an address parameter; and executing a target script file corresponding to each deployment step according to the execution order of each deployment step in the target deployment process, so as to configure the database node on the server.

[0080] According to an embodiment of the present disclosure, the sub-configuration parameter includes an address parameter of a server where the database node is located. Specifically, the address parameter may include an Internet Protocol (IP) address of the server.

[0081] According to an embodiment of the present disclosure, the deployment file may be pre-stored in the database cluster deployment platform, and the deployment file corresponding to the target deployment process instance may be determined according to the deployment database type information, deployment package version information, etc. of the target deployment process instance.

[0082] According to an embodiment of the present disclosure, the deployment steps may include environment initialization, downloading deployment files, installing deployment files, starting services, etc., and may also include operating system environment cleanup and domain name server (DNS) configuration, etc.

[0083] According to an embodiment of the present disclosure, the target script files corresponding to each deployment step can be executed in sequence according to the execution order of each deployment step and the logical relationship between the deployment steps. Specifically, the workflow engine can be used to call and execute the target script files corresponding to each deployment step in sequence.

[0084] According to the embodiments of the present disclosure, since the database nodes of the database cluster may be distributed on multiple servers, the database nodes can be configured for multiple servers at the same time. Specifically, the deployment file can be sent to all servers of the database cluster at the same time, and the target deployment process instance can be executed on each server to configure the database node.

[0085] According to the embodiments of the present disclosure, the deployment efficiency is improved by automatically sending the deployment file to the corresponding server and using the target script file to configure the database node.

[0086] Figure 4 The diagram schematically shows a target deployment process of a deployment cluster according to a specific embodiment of the present disclosure.

[0087] like Figure 4 As shown, the target deployment process of deploying a cluster includes operations S410 to S450.

[0088] In operation S410, parameters are initialized.

[0089] According to an embodiment of the present disclosure, parameter initialization can synthesize configuration parameters into a format required by subsequent deployment steps and verify the number of configuration parameters.

[0090] In operation S420, the medium is downloaded.

[0091] According to an embodiment of the present disclosure, the media download can send the media required for deploying the database cluster to the server.

[0092] In operation S430, the deployment file is issued.

[0093] According to an embodiment of the present disclosure, sending the deployment file may send the deployment file required for deploying the database cluster to the server.

[0094] In operation S440, the environment is initialized.

[0095] According to an embodiment of the present disclosure, the environment initialization may initialize the installation environment of the server, including the system file configuration of the server and the installation of deployment files.

[0096] In operation S450, the database is deployed.

[0097] According to an embodiment of the present disclosure, database deployment can call a script file to deploy database nodes locally on the server.

[0098] According to an embodiment of the present disclosure, the node expansion of the database cluster can also be performed in the database cluster deployment platform. Specifically, the target deployment process of node expansion can include parameter preparation, installation of expansion nodes, and information storage.

[0099] According to an embodiment of the present disclosure, the database cluster deployment method also includes: when it is determined that the target deployment process is not stored in the deployment process library, storing the target deployment process in the deployment process library; generating a target mapping relationship based on the target deployment process and the deployment requirements input by the user; and storing the target mapping relationship in the requirement mapping table.

[0100] According to an embodiment of the present disclosure, it is possible to determine whether a target deployment process has been stored in a deployment process library according to the deployment steps in the target deployment process and the execution information of each deployment step.

[0101] According to an embodiment of the present disclosure, when the target deployment process is not stored in the deployment process library, the target deployment process can be stored in the deployment process library, and the target deployment process can be directly used when other users have the same or similar requirements.

[0102] According to an embodiment of the present disclosure, a deployment process library stores a requirement mapping table, and the requirement mapping table includes a mapping relationship between deployment requirements and deployment processes.

[0103] According to an embodiment of the present disclosure, after storing the target deployment process, in order to recommend the target deployment process to other users with similar needs, a target mapping relationship can be generated according to the target deployment process and the deployment requirements input by the user, and the target mapping relationship can be stored in a requirement mapping table.

[0104] According to an embodiment of the present disclosure, when the target deployment process is stored in the deployment process library, the mapping relationship of the target deployment process can be obtained from the requirement mapping table. When it is determined that the mapping relationship does not include the target mapping relationship, the target mapping relationship is stored in the requirement mapping table.

[0105] According to an embodiment of the present disclosure, by storing the target deployment process and the deployment requirements corresponding to the target deployment process, other users can directly use the target deployment process when they have the same or similar requirements, thereby improving the richness of the deployment processes stored in the deployment process library and meeting diverse user needs.

[0106] According to an embodiment of the present disclosure, in response to receiving a deployment requirement input by a user, determining a deployment process in a deployment process library that matches the deployment requirement as an initial deployment process includes: determining a target deployment requirement from a requirement mapping table according to the deployment requirement input by the user; determining at least one deployment process that has a mapping relationship with the target deployment requirement according to the requirement mapping table; and determining the initial deployment process from at least one deployment process according to the respective evaluation scores of each deployment process in the at least one deployment process.

[0107] According to an embodiment of the present disclosure, the similarity between the target deployment requirement and the deployment requirement input by the user satisfies a predetermined condition. Specifically, when the deployment requirement identical to the deployment requirement input by the user is already included in the requirement mapping table, the deployment requirement identical to the deployment requirement input by the user can be determined as the target deployment requirement, and when the deployment requirement identical to the deployment requirement input by the user is not included in the requirement mapping table, the deployment requirement most similar to the deployment requirement input by the user can be determined as the target deployment requirement.

[0108] According to an embodiment of the present disclosure, when determining the target deployment requirements, priorities may be configured for requirements such as deployment scale, deployment scenario, and deployment database type, for example, the target deployment requirements may be determined preferentially from deployment requirements with the same deployment database type.

[0109] According to the embodiments of the present disclosure, since different users have different deployment habits, different deployment processes may be used even if the deployment requirements are the same, that is, there may be multiple deployment processes that have a mapping relationship with the target deployment requirements.

[0110] According to an embodiment of the present disclosure, each deployment process has an evaluation score, and the evaluation score can represent the quality of the deployment process. When determining the initial deployment process from at least one deployment process, the deployment process with the highest evaluation score can be determined as the initial deployment process.

[0111] According to an embodiment of the present disclosure, the user may also select other deployment processes in the deployment process library as the initial deployment process, or re-customize a new deployment process, without any restriction.

[0112] According to the embodiments of the present disclosure, the most matching initial deployment process is determined based on the evaluation scores of user requirements and deployment processes, thereby improving the matching degree between the initial deployment process and user requirements, thereby improving the user experience.

[0113] According to an embodiment of the present disclosure, the database cluster deployment method also includes: in response to determining that the execution of the target deployment process instance is completed, obtaining the execution time of the target deployment process instance; and generating an evaluation score for the target deployment process based on the execution time, the number of times the target deployment process is used, and the user's evaluation information on the target deployment process.

[0114] According to an embodiment of the present disclosure, the execution duration can be calculated based on the start time and end time of the target deployment process instance, and the deployment speed of the target deployment process in the actual deployment process can be evaluated based on the execution duration.

[0115] According to an embodiment of the present disclosure, the number of times the target deployment process is used may be the number of times the target deployment process is used after being created. The greater the number of times the target deployment process is used, the more the target deployment process meets the deployment requirements of the user.

[0116] According to an embodiment of the present disclosure, after the target deployment process instance is executed, an evaluation interface may be displayed to the user, and the user may input evaluation information for the target deployment process in the evaluation interface.

[0117] According to an embodiment of the present disclosure, when the target deployment process instance fails to execute, or the user destroys the database cluster deployed using the target deployment process instance, the evaluation score of the target deployment process may be reduced accordingly.

[0118] According to an embodiment of the present disclosure, by utilizing various information including execution time, number of uses, and user evaluation information, the evaluation score of the target deployment process is determined, thereby improving the accuracy of the evaluation score, so that the initial deployment process determined according to the evaluation score can better meet user needs and improve user experience.

[0119] Figure 5 The schematic diagram shows the structure of a database cluster deployment platform according to a specific embodiment of the present disclosure.

[0120] like Figure 5 As shown, the database cluster deployment platform includes a deployment process library 510, a process arrangement module 520, a file management module 530, a resource management module 540, an information integration module 550 and a user evaluation module 560. Through the database cluster deployment platform, a database cluster can be deployed in a server 570 where a database cluster is to be deployed.

[0121] According to an embodiment of the present disclosure, the deployment process library 510 can be used to store the target deployment process generated after the user performs a custom operation. In addition, the deployment process library 510 also stores a requirement mapping table, which includes a mapping relationship between deployment requirements and deployment processes. The requirement mapping table can be used to recommend deployment processes that meet the deployment requirements to users.

[0122] According to the embodiment of the present disclosure, the process orchestration module 520 mainly completes the definition of deployment steps in the deployment process, component definition, blueprint definition, service definition and the flow drive of the target deployment process instance.

[0125] According to the embodiments of the present disclosure, since the database cluster deployment platform needs to adapt to different database types, it corresponds to different installation configuration files, different configuration media, and different deployment processes. Therefore, the information integration module 550 needs to integrate the required configuration parameters and deployment process according to the database type selected by the user in the front-end interface and send them to the process orchestration module 520 for actual deployment.

[0126] According to the embodiments of the present disclosure, the information integration module 550 can be used for information collection and information processing of various database types. Information collection refers to collecting relevant deployment information of the selected database, including deployment files, address parameters, and memory resource configuration parameters; information processing mainly involves arranging the parameters of the collected information according to the interface or shell script file input format, and associating it with the target deployment process instance to deploy the database cluster.

[0127] According to an embodiment of the present disclosure, the user evaluation module 560 can be used to construct an evaluation system for the deployment process, and score the deployment process according to the frequency of use of the deployment process, the execution time, whether the deployment process is destroyed and reconstructed, and the user's evaluation information on the deployment process. When the user is deploying, the deployment process that meets the deployment requirements can be displayed according to the evaluation score from high to low.
