[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0031] To address the technical problem in existing technologies where direct modification of computing node configuration files can easily lead to errors and cause applications to fail to provide services, this application provides a method for updating application service configurations that eliminates the need for direct modification of computing node configuration files, thus avoiding errors.

[0032] Figure 1 This is a flowchart illustrating a service configuration update method for an application provided in an embodiment of this application. Figure 1 As shown, the service configuration update method for the above application includes:

[0033] S102, when the target cluster receives an online request indicating that the service configuration is online, the service configuration in the target cluster is synchronized to the data center cluster. Each of the multiple data centers includes a data center cluster, and the data center cluster is a cluster in each of the multiple data centers.

[0034] S104, where the server cluster in each data center stores the service configuration of the data center cluster in the memory of the server cluster, where the server cluster is a cluster that has the application deployed.

[0035] S106, when any server cluster receives an access request, the service configuration is called from memory to provide the target service using the service configuration. The target service is the service corresponding to the service configuration, and the access request is used to access the target service of the application on any server cluster.

[0036] The above-described method for updating service configurations can be applied to the process of updating service configurations in a server cluster where the application is deployed.

[0037] Applications are deployed on server clusters. Different server clusters can belong to different data centers. In addition to server clusters, data centers can also include data center clusters. Data center clusters are used to synchronize service configurations with the target cluster (central service configuration cluster) outside the data center. The relationship diagram is as follows: Figure 2 As shown. The target cluster includes multiple nodes, with master and child nodes. The data center includes a data center cluster, which in turn includes master and child nodes. The data center cluster communicates with the server cluster through proxy nodes. The server cluster periodically pulls the service configuration from the data center cluster into its memory. Applications in the server cluster then provide services using the service configuration in the server cluster's memory.

[0038] The target cluster and data center cluster mentioned above can be an etcd cluster. etcd is a distributed, consistent key-value storage system used for shared configuration and service discovery. An etcd cluster can include multiple nodes, including a master node and child nodes. Using the etcd cluster as the target cluster, users can send requests to the master node through an etcd client to adjust the service configuration within the etcd cluster. The master node then sends the service configuration to the child nodes. After confirming the service configuration is adjusted correctly, a deployment request can be initiated, and the target cluster will deploy the service configuration online, synchronizing it with the etcd cluster in the data center. During synchronization with the etcd cluster in the data center, the master node is synchronized first, and then the master node sends the service configuration to the child nodes. For example, as shown... Figure 3 As shown, Figure 3 In the target cluster, node 1 is the master node, and nodes 2 and 3 are child nodes. In data center cluster 1 and data center cluster 2, node 2 is the master node, and nodes 1 and 3 are child nodes. The master node will synchronize the written data to the child nodes.

[0039] The server cluster described above can be a cluster with applications deployed on it. The server cluster pulls the service configuration from the etcd cluster in the data center into memory and stores it there. When the application needs to call the service configuration, it can call the service configuration in memory.

[0040] In this embodiment, when a user adjusts the service configuration on the target cluster through the client of the target cluster and initiates an online request, the target cluster will synchronize the service configuration to the data center cluster. Then, the service configuration in the data center cluster will be stored in the memory of the server cluster within the same data center. When an application on the server cluster receives an access request, it will invoke the service configuration to provide the corresponding service.

[0041] The method provided in this application embodiment can modify the service configuration uniformly through the target cluster. When the target cluster receives a service configuration online request, the modified service configuration can be synchronized to the data center cluster. The service configuration synchronized to the data center cluster will be saved in memory by the server cluster for the server cluster to call to provide the target service. This eliminates the need to directly modify the configuration file in the server cluster, avoids errors, and ensures that the application of the server cluster provides normal service.

[0042] As an optional example, such as Figure 4 As shown, when the target cluster receives an online request indicating that the service configuration is online, synchronizing the service configuration in the target cluster to the data center cluster includes:

[0043] S402, determine the target configuration that has changed in the service configuration of the target cluster, wherein the service configuration of the target cluster includes the data center service configuration of each data center and the shared service configuration shared by all data centers;

[0044] S404-1, when the target configuration is a data center service configuration, determine the target data center corresponding to the target configuration and synchronize the target configuration to the data center cluster of the target data center;

[0045] S404-2, when the target configuration is a shared service configuration, synchronizes the target configuration to the data center cluster in each data center.

[0046] In this embodiment, users can adjust the service configuration in the target cluster through the client. During online synchronization, they can either synchronize only the service configurations that have changed compared to the last time, or synchronize all service configurations. For the case where service configurations have changed, the first step is to determine the target configuration that has changed. The service configuration of the target cluster includes the data center service configuration for each data center and the shared service configuration shared by all data centers. It is determined whether the target configuration is a data center service configuration or a shared service configuration. If it is a data center service configuration, only the corresponding data center cluster needs to be synchronized; if it is a shared service configuration, it needs to be synchronized to the data center cluster of every data center.

[0047] As an optional example, the service configurations in the target cluster and the data center cluster are stored in a tree-like hierarchical structure. Before determining the target configuration that has changed in the service configuration of the target cluster, the above method further includes: synchronizing the data center service configuration in the service configuration of the target cluster to the data center cluster that matches the data center service configuration according to the tree-like hierarchical structure of the service configuration of the target cluster; or, synchronizing the shared service configuration in the service configuration of the target cluster to each data center cluster according to the tree-like hierarchical structure of the service configuration of the target cluster.

[0048] In this embodiment, the service configuration in the target cluster is stored in a tree-like hierarchical structure. When synchronized to the data center cluster, the storage structure of the data center service configuration synchronized to the data center cluster is consistent with that of the service configuration in the target cluster, both being tree-like hierarchical structures.

[0049] For example, such as Figure 5 This is a schematic diagram of a tree-like hierarchical structure. The service configurations of Data Center 1, Data Center 2, and Data Center 3 are data center service configurations, which are synchronized to the data center clusters of Data Center 1, Data Center 2, and Data Center 3, respectively. The shared data center configuration is synchronized to the data center clusters of Data Center 1, Data Center 2, and Data Center 3. Taking the data center service configuration of Data Center 2 as an example, the data center service configuration of Data Center 2 is divided into availability zone level, cluster level, compute node level, and service level. After the data center service configuration of Data Center 2 is synchronized to the data center cluster of Data Center 2, the data center service configuration of Data Center 2 is stored in the data center cluster of Data Center 2 with the same structure.

[0050] As an optional example, synchronizing the data center service configuration in the service configuration of the target cluster to data center clusters matching the data center service configuration according to the tree hierarchy of the service configuration of the target cluster, or synchronizing the shared service configuration in the service configuration of the target cluster to each data center cluster according to the tree hierarchy of the service configuration of the target cluster, includes: determining each data center cluster as the current cluster, and performing the following operations: obtaining a first path or a second path in the current cluster, wherein the first path is used to indicate the path of the data center service configuration to be synchronized to the current cluster in the target cluster, and the second path is used to indicate the path of the shared service configuration to be synchronized to the current cluster; synchronizing the data center service configuration to the current cluster according to the first path or synchronizing the shared service configuration to the current cluster according to the second path.

[0051] In this embodiment, each data center cluster contains two paths: a first path and a second path. The first path indicates the data center service configuration corresponding to the data center cluster in the target cluster. The second path is the path for shared service configuration. The first path is different for data center clusters in different data centers, but the second path is the same for all data center clusters. For example, continuing to combine... Figure 5 The first path for the data center cluster in Data Center 2 can be `key:="Data Center 2 / Availability Zone 2 / Cluster 3 / Compute Node 1 / Service"`, and the second path can be ` / Shared Data Center Configuration / Service Group / Service 1`, or ` / Shared Data Center Configuration / Service Group / Service 2`. Whether it's `Service 1` or `Service 2` depends on the required services, or both `Service 1` and `Service 2` can be synchronized.

[0052] As an optional example, synchronizing the data center service configuration to the current cluster according to the first path or synchronizing the shared service configuration to the current cluster according to the second path includes: determining each string separated by a predetermined symbol in the first path as a node; performing node resolution operations from the first node to the last node in the first path; and loading the node into the current cluster each time a non-duplicate node is resolved; or, determining each string separated by a predetermined symbol in the second path as a node; performing node resolution operations from the first node to the last node in the second path; and loading the node into the current cluster each time a non-duplicate node is resolved.

[0053] In this embodiment, during the process of synchronizing service configuration according to the first path or the second path, the first path and the second path can be parsed, and a predetermined symbol in the first path and the second path can be used as a separator. The predetermined symbol can be " / " in the path. After parsing the first path and the second path, each node obtained from the parsing is loaded into the data center cluster. Figure 6 As shown, taking data center 2 as an example, the service configuration of data center 2 is saved in the data center cluster of data center 2 in the form of a tree-like hierarchical structure, which is consistent with the hierarchical structure of the service configuration of data center 2 in the target cluster.

[0054] As an optional example, storing the service configurations for the data center cluster in the memory of the server cluster within each data center includes:

[0055] S702, where the server cluster in each data center pulls the service configuration of the data center cluster from the data center cluster at predetermined intervals;

[0056] S704-1: If the service configuration is successfully pulled, the pulled service configuration will overwrite the original service configuration in memory.

[0057] S704-2 retains the original service configuration in memory in the event that fetching the service configuration fails.

[0058] In this embodiment, the server cluster can periodically pull data center service configurations and shared service configurations from the data center cluster into memory, such as every 10 minutes. If the pull is successful, the pulled service configuration overwrites the original service configuration in memory. It should be noted that the pulled service configuration may be identical to the original service configuration; in such cases, it will still be overwritten to ensure that the service configuration in memory is up-to-date. Before the pulled service configuration overwrites the original service configuration, if a user access request is received, the original service configuration in memory will be used to provide the service, as the new service configuration has not yet been pulled. After the pulled service configuration overwrites the original service configuration, when a user access request is received, the new service configuration will be used.

[0059] As an optional example, when the target cluster receives an online request indicating that the service configuration is online, synchronizing the service configuration in the target cluster to the data center cluster includes: saving the service configuration as an executable file; and copying and pasting the executable file format service configuration into the data center cluster.

[0060] In this embodiment, the service configuration in the target cluster can be saved as an executable file during synchronization. This executable file can then be directly copied and pasted to complete the service configuration synchronization. The executable file is identical in both the target cluster and the data center cluster.

[0061] Figure 8 This is a system flowchart for this embodiment, described in conjunction with the accompanying drawings. Users update service configurations in the target cluster using an etcd client. The etcd client displays service configurations in a hierarchical tree structure for easy management and display. Furthermore, the etcd client supports user authentication and Transport Layer Security (TLS). The target cluster is an etcd cluster with the following characteristics: High availability: etcd supports a multi-replica architecture, ensuring high availability of configurations. Real-time updates: etcd can synchronize configuration updates in real time, ensuring real-time configuration. Version control support: etcd supports configuration version control, allowing easy rollback to historical versions. TLS encryption support: etcd supports TLS encryption, ensuring the security of configuration data. Access control support. After the service configuration of the target cluster is updated, it is synchronized online to the data center cluster. Online synchronization uses a step tool, which can operate according to executable file commands, allowing copying, pasting, and deleting of service configurations. The server cluster periodically pulls service configurations, and the service configurations of the data center cluster are periodically forwarded to the server cluster through proxy nodes. The proxy node is a stateless etcd reverse proxy running on the open-source framework (gRPC Remote Procedure Calls, gRPC), designed to reduce the overall processing load on the core etcd cluster. The gRPC proxy node merges monitoring and API call requests, achieving horizontal scalability. Simultaneously, to protect the cluster from abusive clients, the gRPC proxy node implements a key-value pair read request cache. Applications in the server cluster invoke in-memory service configurations to provide the corresponding services.

[0062] The data center cluster references the service configuration of the target cluster through a first path and a second path. For example, the first path could be `key:="Data Center 2 / Availability Zone 2 / Cluster 3 / Compute Node 1 / Service"`. The second path for the data center cluster in Data Center 2 could be `Second Path: / Shared Data Center Configuration / Service Group / Service 1`, or `Second Path: / Shared Data Center Configuration / Service Group / Service 2`. The service configuration obtained by the data center cluster consists of two parts. The first part is separated by a key and parsed layer by layer. If duplicate configuration items are encountered, the configuration of the lower-level node takes precedence. The second part is the shared service configuration, parsed layer by layer, and finally saved as a structure identical to the tree hierarchy in the target cluster.

[0063] Figure 9 This is a schematic diagram illustrating the structure of a service configuration update system for an application provided in an embodiment of this application. Figure 9 As shown, the service configuration update system for the above application includes:

[0064] Target cluster 902 is used to synchronize the service configuration in the target cluster to the data center cluster when it receives an online request indicating that the service configuration is online. The target cluster is a cluster located outside of multiple data centers, and each of the multiple data centers includes one of the aforementioned data center clusters.

[0065] Data center cluster 904 is used to store service configurations;

[0066] Server cluster 906 is used to store the service configuration of the data center cluster in the memory of the server cluster, where the server cluster is a cluster on which the application is deployed; when an access request is received, the service configuration is retrieved from memory to provide the target service using the service configuration, where the target service is the service corresponding to the service configuration, and the access request is used to access the target service of the application on any server cluster.

[0067] The service configuration update system described above can be used to update the service configuration in a server cluster where the application is deployed.

[0068] Applications are deployed on server clusters. Different server clusters can belong to different data centers. In addition to server clusters, data centers can also include data center clusters. Data center clusters are used to synchronize service configurations with the target cluster (central service configuration cluster) outside the data center. The relationship diagram is as follows: Figure 2 As shown. The target cluster includes multiple nodes, with master and child nodes. The data center includes a data center cluster, which in turn includes master and child nodes. The data center cluster communicates with the server cluster through proxy nodes. The server cluster periodically pulls the service configuration from the data center cluster into its memory. Applications in the server cluster then provide services using the service configuration in the server cluster's memory.

[0069] The target cluster and data center cluster mentioned above can be an etcd cluster. etcd is a distributed, consistent key-value storage system used for shared configuration and service discovery. An etcd cluster can include multiple nodes, including a master node and child nodes. Using the etcd cluster as the target cluster, users can send requests to the master node through an etcd client to adjust the service configuration within the etcd cluster. The master node then sends the service configuration to the child nodes. After confirming the service configuration is adjusted correctly, a deployment request can be initiated, and the target cluster will deploy the service configuration online, synchronizing it with the etcd cluster in the data center. During synchronization with the etcd cluster in the data center, the master node is synchronized first, and then the master node sends the service configuration to the child nodes. For example, as shown... Figure 3 As shown, Figure 3 In the target cluster, node 1 is the master node, and nodes 2 and 3 are child nodes. In data center cluster 1 and data center cluster 2, node 2 is the master node, and nodes 1 and 3 are child nodes. The master node will synchronize the written data to the child nodes.

[0070] The server cluster described above can be a cluster with applications deployed on it. The server cluster pulls the service configuration from the etcd cluster in the data center into memory and stores it there. When the application needs to call the service configuration, it can call the service configuration in memory.

[0071] In this embodiment, when a user adjusts the service configuration on the target cluster through the client of the target cluster and initiates an online request, the target cluster will synchronize the service configuration to the data center cluster. Then, the service configuration in the data center cluster will be stored in the memory of the server cluster within the same data center. When an application on the server cluster receives an access request, it will invoke the service configuration to provide the corresponding service.

[0072] The method provided in this application embodiment can modify the service configuration uniformly through the target cluster. When the target cluster receives a service configuration online request, the modified service configuration can be synchronized to the data center cluster. The service configuration synchronized to the data center cluster will be saved in memory by the server cluster for the server cluster to call to provide the target service. This eliminates the need to directly modify the configuration file in the server cluster, avoids errors, and ensures that the application of the server cluster provides normal service.
