Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0042] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0043] First, some nouns or terms that appear in the description of the embodiments of this application shall be interpreted as follows:
[0044] 1. Task-service: A scheduled task used to periodically scan all clusters and set the default cluster.
[0045] 2. Layer 7 Load Balancing: Layer 7 load balancers reside at the highest layer of the OSI model, the application layer. They analyze and process network traffic, distributing requests to different servers to achieve load balancing. This load balancing method intelligently distributes traffic based on application layer protocols (such as HTTP, HTTPS, SMTP, etc.), thereby improving server performance and reliability.
[0046] 3. Tengine_host: A real physical machine; the cluster exists in the form of physical machines.
[0047] According to one aspect of the embodiments of this application, a cluster adjustment method is provided. Optionally, in this embodiment, the above-described cluster adjustment method can be applied to, for example... Figure 1 The hardware environment shown consists of terminal 1402 and server 1404. For example... Figure 1 As shown, server 1404 is connected to terminal 1402 via a network and can be used to provide services (such as game services, application services, etc.) to the terminal or clients installed on the terminal. A database can be set up on the server or independently of the server to provide data storage services for server 1404.
[0048] The aforementioned network may include, but is not limited to, at least one of the following: wired network, wireless network. The aforementioned wired network may include, but is not limited to, at least one of the following: wide area network, metropolitan area network, local area network. The aforementioned wireless network may include, but is not limited to, at least one of the following: Wi-Fi (Wireless Fidelity), Bluetooth. The terminal is not limited to PC, mobile phone, tablet computer, etc.
[0049] The cluster adjustment method of this application embodiment can be executed by a server, a terminal, or both. Alternatively, the cluster adjustment method of this application embodiment can be executed by a client installed on the terminal.
[0050] Taking the cluster adjustment method in this embodiment as an example, which is executed by the server, Figure 2 A cluster adjustment method provided in this application includes the following steps:
[0051] Step S202: Obtain the cluster status of the target cluster.
[0052] The cluster adjustment method in this embodiment can be applied to scenarios that require creating, deleting, or setting a default cluster.
[0053] In this embodiment, the target cluster can be any cluster that requires cluster management.
[0054] Cluster status can be the state of the cluster after the cluster administrator performs operations on the target cluster. For example, when the administrator creates a physical machine in the target cluster, the corresponding cluster status can be "new physical machine"; when the administrator deletes a physical machine in the target cluster, the corresponding cluster status can be "deleted physical machine", and so on.
[0055] Step S204: Determine the target adjustment actions to be performed on the target cluster based on the cluster status.
[0056] After obtaining the cluster status, the corresponding target adjustment action can be executed according to the cluster status. Optionally, candidate adjustment actions corresponding to different types of cluster status can be pre-defined, so that after determining the cluster status of the target cluster, the target adjustment action corresponding to the target cluster can be matched among all candidate adjustment actions according to the cluster status.
[0057] Step S206: Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster.
[0058] Once the target adjustment action is determined, the target adjustment action can be executed on the target cluster to complete the adjustment of the target cluster.
[0059] In this embodiment, the cluster status of the target cluster is obtained; the target adjustment action to be performed on the target cluster is determined based on the cluster status; and the target adjustment action is performed on the target cluster to complete the adjustment of the target cluster. Since the target adjustment action to be performed on the target cluster can be automatically determined based on the cluster status of the target cluster, and the target cluster is adjusted through this target adjustment cluster, the purpose of automatic cluster management can be achieved, thus simplifying the complexity of cluster management and solving the problem of complex cluster management in related technologies.
[0060] As an optional implementation, as described above, the target adjustment action to be performed on the target cluster is determined based on the cluster status, including: if it is determined based on the cluster status that a new physical machine will be added to the target cluster, the target adjustment action to be performed on the target cluster is determined to be a cluster creation action.
[0061] Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster, including: creating a target sub-cluster based on the new physical machine by performing a cluster creation action.
[0062] In other words, when the cluster status indicates that the cluster administrator should add a new physical machine to the target cluster, the target adjustment action to be performed on the target cluster is determined to be a cluster creation action. A cluster creation action is an action that creates a new sub-cluster under the target cluster. In this embodiment, the target cluster can be a large cluster consisting of all physical machines corresponding to a certain user. A sub-cluster can be a small cluster within the large cluster, targeting a specific service or usage scenario. If the target adjustment action is determined to be a cluster creation action, then by executing the cluster creation action, a target sub-cluster consisting of the new physical machine can be automatically created.
[0063] As an optional implementation, the method described above determines the target adjustment actions to be performed on the target cluster based on the cluster state, including:
[0064] If the cluster status determines the specific physical machine to be deleted from the target cluster, the target adjustment action to be performed on the target cluster is determined to be the cluster deletion action.
[0065] Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster, including: deleting the specified sub-cluster, which includes the specified physical machine, by performing a cluster deletion action.
[0066] In other words, when the cluster status indicates that the cluster administrator should delete a specified physical machine under the target cluster, the target adjustment action to be performed on the target cluster is determined to be a cluster deletion action. A cluster deletion action is an action that deletes an existing sub-cluster under the target cluster. In this embodiment, the specified physical machine can be the collection of all physical machines under a certain sub-cluster. If the target adjustment action is determined to be a cluster deletion action, then executing the cluster deletion action will automatically delete the self-generated sub-cluster composed of the specified physical machine.
[0067] As an optional implementation, as described above, the target adjustment action to be performed on the target cluster is determined based on the cluster state, including: when a target value for modifying the public field value of the target sub-cluster in the target cluster is obtained based on the cluster state, the target adjustment action to be performed on the target sub-cluster is determined to be a cluster publicity adjustment action.
[0068] Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster, including: modifying the public field value to the target value by performing cluster publicity adjustment actions, and modifying the cluster publicity of the target sub-cluster to the target publicity indicated by the target value.
[0069] Specifically, cluster administrators can distinguish between public and private clusters by setting the value of the `shared` field (i.e., the publicity field value) of the cluster or sub-cluster. When the cluster status indicator shows that the publicity field value for a target sub-cluster has been modified to the target value, it indicates that a cluster publicity adjustment action is needed for the target sub-cluster. This can then be performed to modify the publicity field value to the target value and change the target sub-cluster's publicity to the target value's indicated publicity. Publicity can include both publicly accessible public sub-clusters and privately accessible clusters. For example, if the target value for modifying the `shared` field value for a target sub-cluster is True, then the value of the `shared` field is changed to True, and the target sub-cluster's publicity is changed to public.
[0070] As an optional implementation, the method described above determines the target adjustment action to be performed on the target cluster based on the cluster state, including: if the cluster state determines that the common sub-cluster with the fewest current listeners in the target cluster is the target common sub-cluster, the target adjustment action is determined to be the default cluster adjustment action.
[0071] Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster, including: by performing default cluster adjustment actions, caching the cluster identifier of the target common sub-cluster to the preset storage area, so as to use the target common sub-cluster as the default cluster, wherein the preset storage area is used to cache the cluster identifier of the default cluster.
[0072] In other words, the method in this embodiment is used to select the default cluster: by periodically scanning the task_service, the target common sub-cluster with the fewest listeners is selected from the clusters where shared=True (i.e., common sub-clusters), and the target adjustment action is determined to be the default cluster adjustment action. Then, by executing the default cluster adjustment action, the cluster identifier of the target common sub-cluster is cached in a preset storage area, so that the target common sub-cluster is used as the default cluster, and subsequent listener requests are forwarded to the target common sub-cluster by default. Optionally, the cluster identifier can be cached using Redis (Remote Dictionary Server, an open-source, high-performance key-value store system, commonly used as a database, cache, and message broker). Since Redis is an in-memory database, the preset storage area is a storage area in memory.
[0073] As an optional implementation, the method described above determines the target adjustment action to be performed on the target cluster based on the cluster state, including: when the cluster state is to obtain a listener creation request to create a listener in the target cluster, the target adjustment action is determined to be a listener creation action.
[0074] Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster, including: if the listener creation request includes a specified cluster identifier, create a listener to forward the request to the specified cluster indicated by the specified cluster identifier by performing a listener creation action; if the listener creation request does not include any cluster identifier, obtain a default cluster identifier from the preset storage area and create a specified listener to forward the request to the default cluster indicated by the default cluster identifier.
[0075] Specifically, when creating a listener, if the listener creation request includes a specified cluster identifier, it indicates that the cluster to which the request corresponding to the listener to be created is to be forwarded has been specified, and a listener is created to forward the request to the specified cluster indicated by the specified cluster identifier. If the listener creation request does not include any cluster identifier, it indicates that no cluster has been specified, and a default cluster identifier is automatically obtained from a preset storage area (e.g., Redis), and a specified listener is created to forward the request to the default cluster indicated by the default cluster identifier. In other words, all requests to this specified listener will be forwarded to the default cluster later. Furthermore, if no arbitrary cluster identifier is included, and Redis does not contain any default cluster identifier, a new cluster name is generated based on the cluster type name, a new cluster is created based on the generated cluster name, and the newly created cluster is associated with the listener.
[0076] As an optional implementation, the method described above determines the target adjustment actions to be performed on the target cluster based on the cluster state, including:
[0077] If the cluster status determines that the last host of the current default sub-cluster in the target cluster has been deleted or the publicness field value of the current default sub-cluster has been modified, the target adjustment action is determined to be the default cluster reset action.
[0078] Perform target adjustment actions on the target cluster to complete the adjustment of the target cluster, including: determining a new default sub-cluster in the target cluster by performing a default cluster reset action.
[0079] Specifically, the current default sub-cluster is the sub-cluster currently used as the default sub-cluster in the target cluster.
[0080] In other words, when the last host in the current default sub-cluster cluster is deleted or its shared settings are changed (i.e., the public field value of the current default sub-cluster cluster is modified and it is adjusted to a private cluster), if there is no current default sub-cluster cluster or a new default sub-cluster cluster is determined, the target adjustment action is a default cluster reset action. This default cluster reset action can then be executed to determine a new default sub-cluster cluster in the target cluster. Furthermore, the new default sub-cluster cluster can be the sub-cluster cluster with the lowest load in the target cluster (e.g., the fewest associated listeners).
[0081] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application.
