Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
The embodiment of the invention provides a cluster management method, cluster management equipment for realizing the method and a cluster system for the method. Fig. 1 is a schematic diagram of main components of a cluster system according to an embodiment of the present invention, and as shown in fig. 1, the cluster system includes a cluster and a cluster management device. The cluster management device provides the cluster management method of the embodiment of the invention, and is an execution subject of the cluster management method of the embodiment of the invention.
Fig. 2 is a schematic diagram of main flow of a cluster management method according to an embodiment of the present invention, as shown in fig. 1, where the cluster management method includes: step S201, step S202, and step S203.
In step S201, a configuration file to be synchronized uploaded by a first cluster device in a cluster is received. The cluster comprises two or more cluster devices, and the first cluster device is any cluster device in the cluster.
In some alternative embodiments, the first cluster device is a reference device selected when creating a cluster or performing a configuration information consistency operation on the cluster (an operation for keeping configuration information of individual cluster devices within the cluster consistent). Before receiving the configuration file to be synchronized uploaded by the first cluster device in the cluster, the method further comprises the following steps: screening a first cluster device from all cluster devices in the cluster to serve as a reference device according to a file synchronization request of a user, so that the reference device uploads a stored configuration file; the configuration file to be synchronized is the configuration file uploaded by the reference device. And selecting one reference device, and synchronizing other cluster devices in the cluster by taking the configuration files in the reference device as templates, so that the consistency of the configuration information of each cluster device in the whole cluster can be efficiently and accurately ensured.
Further, after the first cluster device is screened from all cluster devices in the cluster to serve as a reference device, a lock of the configuration file to be synchronized can be allocated to the reference device in response to a lock acquisition request of the reference device, so that the reference device locks the configuration file to be synchronized before uploading the configuration file to be synchronized, and unlocks the configuration file to be synchronized after uploading the configuration file to be synchronized.
The management device can record the lock state of each configuration file stored in the management device, including a locked state and an unlocked state, and the configuration file in the locked state can only be modified by the cluster device locked with the management device and cannot be modified by other cluster devices. After unlocking, other devices may modify the configuration file. In this embodiment, a lock is introduced, and the cluster device can modify the configuration file only after obtaining the lock of the configuration file, so that a situation that multiple cluster devices modify the same configuration file at the same time can be avoided, and accuracy of configuration information consistency operation is ensured.
In other alternative embodiments, the first cluster device is any cluster device within the cluster that is to modify configuration information of the cluster. Before receiving a configuration file to be synchronized uploaded by a first cluster device in a cluster, modifying the configuration file stored by the first cluster device according to a file modification request of a user so as to enable the first cluster device to store and upload the modified configuration file; the configuration file to be synchronized is a modified configuration file uploaded by the first cluster device.
After all other cluster devices in the cluster synchronize with the configuration file in the reference device as a template, the cluster device uploads the configuration file after modification to the management device no matter which cluster device locally stores the configuration file, and all other cluster devices in the cluster only need to download and update from the management device.
In this embodiment, the configuration file is modified in any cluster device in the cluster, and the modified configuration file is automatically synchronized to other cluster devices in the cluster through the management device, so that manual operation can be avoided, complexity and workload of the cluster device configuration information consistency operation are greatly reduced, and efficiency and accuracy of the configuration information consistency operation are improved.
Optionally, after modifying the configuration file stored by the first cluster device, the method further includes: the configuration file to be synchronized is locked before the first cluster equipment uploads the configuration file to be synchronized, and the configuration file to be synchronized is unlocked after the first cluster equipment uploads the configuration file to be synchronized; or, in response to a lock acquisition request of the first cluster device, distributing the lock of the configuration file to be synchronized for the first cluster device, so that the first cluster device locks the configuration file to be synchronized before uploading the configuration file to be synchronized, and unlocks the configuration file to be synchronized after uploading the configuration file to be synchronized.
FIG. 4 is a flow chart of a modification of a configuration file according to some embodiments of the invention. As shown in fig. 4, the method comprises the following steps: step S401, the management device modifies the configuration file A stored in the first cluster device according to the file modification request of the user; step S402, locking the configuration file A; step S403, the first cluster equipment uploads the modified configuration file A to the management equipment; step S404, the management device stores the modified configuration file A and records the file version information of the configuration file A. The management device can record the lock state of each stored configuration file, including a locked state and an unlocked state, and the configuration file in the locked state can only be modified by the corresponding cluster management device and cannot be modified by other cluster devices. For example, if the user modifies the configuration file a1 of the cluster device a through the management device, only the cluster device a can modify the configuration file a1 after the management device locks the configuration file a1, and other cluster devices cannot modify the configuration file a 1. After unlocking, other cluster devices may modify the configuration file a 1.
FIG. 5 is a flow chart of a modification of a configuration file according to still other embodiments of the present invention. As shown in fig. 5, the method comprises the following steps: step S501, the management device modifies the configuration file A stored in the first cluster device according to the file modification request of the user; step S502, a first cluster device sends a lock acquisition request to a management device; step S503, the management device is a lock of the first cluster device fragment configuration file A; step S504, the first management device locks the configuration file A, and then uploads the modified configuration file A to the management device; step S504, the management device stores the modified configuration file A and records the file version information of the configuration file A. The management device can record the lock state of each configuration file stored in the management device, including a locked state and an unlocked state, and the configuration file in the locked state can only be modified by the cluster device locked with the management device and cannot be modified by other cluster devices. For example, if the user modifies the configuration file a1 of the cluster device b through the management device, only the cluster device b may modify the configuration file a1 after the cluster device b locks the configuration file a1, and other cluster devices may not modify the configuration file a 1. After unlocking, other cluster devices may modify the configuration file a 1.
In this embodiment, a lock is introduced, and the cluster device can modify the configuration file only after obtaining the lock of the configuration file, so that a situation that multiple cluster devices modify the same configuration file at the same time can be avoided, and accuracy of configuration information consistency operation is ensured.
It should be noted that, when uploading the modified configuration file, only the incremental configuration file may be uploaded, or the full configuration file may be uploaded. For example, if only the first configuration information is modified, the configuration file C may be uploaded only by using the modified first configuration information as the configuration file to be synchronized, or may be uploaded by using the modified complete configuration file C as the configuration file to be synchronized. Of course, the delta configuration file and the full configuration file may also be uploaded at the same time. In the actual application process, for a certain version of configuration file, the incremental configuration file can be uploaded first, and then the configuration file including the certain version of configuration file and the corresponding whole of each incremental configuration file are uploaded as the configuration file to be synchronized periodically. Illustratively, the current file version of configuration file D is V2.0, which includes 10 pieces of configuration information. The user modifies the first piece of configuration information in the V2.0 version of configuration file D, and the modified first piece of configuration information is used as the configuration file to be synchronized for uploading; if the user modifies the second piece of configuration information in the V2.0 version of configuration file D again, uploading the modified second piece of configuration information serving as the configuration file to be synchronized; and uploading the V2.0 version of configuration file D and the whole of the configuration file to be synchronized corresponding to each modification as a new configuration file to be synchronized after several modifications or after a set time. In this way, resource consumption can be reduced.
In step S202, the configuration file to be synchronized is saved, and file synchronization information is generated. The file synchronization information includes a unique identification (e.g., file name, file code, etc.) of the file that uniquely represents one of the configuration files to be synchronized. In this step, all the configuration files to be synchronized are saved by the management device. When the configuration file to be synchronized is saved, the configuration file to be synchronized can be saved according to the name of the configuration file to be synchronized or renamed, and the file version information of the configuration file can be recorded at the same time. By recording the file version information of the configuration file, management of each version of the configuration file is facilitated, the history version evolution process of the configuration file is also facilitated to be checked, and version rollback is performed on the configuration file when needed. By recording the file size, the unique file identification, the file verification information and the like of the configuration file to be synchronized, the cluster equipment can conveniently verify the configuration file to be synchronized after downloading the configuration file to be synchronized, so that the correctness and the integrity of the downloaded configuration file to be synchronized are ensured.
In step S203, the file synchronization information is sent to other devices in the cluster, so that the other devices synchronize their stored configuration files according to the configuration files to be synchronized. The other devices refer to cluster devices except the first cluster device in the cluster. By uniformly storing and managing the configuration information of all the cluster devices in the cluster and automatically synchronizing the configuration files to be synchronized, which are uploaded by any one cluster device in the cluster, to other cluster devices in the cluster after receiving the configuration files to be synchronized, manual operation can be avoided, complexity and workload of the cluster device configuration information consistency operation are greatly reduced, and efficiency and accuracy of the consistency operation are improved.
In some alternative embodiments, the file synchronization information includes: file version information of the configuration file to be synchronized; after sending the file synchronization information to other devices in the cluster, the method further comprises: receiving a file downloading request sent by other equipment, and sending a configuration file to be synchronized corresponding to the file downloading request to the other equipment; the file download request is generated by the other device in case that the file version of the configuration file stored by the other device is not consistent with the file version information of the configuration file to be synchronized.
After receiving the file downloading request sent by the other device, the method may further include: and transmitting the file verification information of the configuration file to be synchronized corresponding to the file downloading request to the other equipment, so that the other equipment verifies the configuration file to be synchronized according to the file verification information, and stores the configuration file to be synchronized and the file version information when the verification passes.
Fig. 3 is a schematic flow chart of a cluster device synchronization profile in an alternative embodiment of the present invention, and as shown in fig. 3, the flow chart of the cluster device synchronization profile includes:

The method for cluster management according to the embodiment of the present invention is described in the following by way of example with reference to a specific application scenario. In this example, the cluster system includes a cluster and a cluster management device, where the cluster management device is an execution body for implementing the method of cluster management according to the embodiment of the present invention. The cluster comprises a plurality of cluster devices, and the cluster devices acquire information of a certain configuration file from the management device, wherein the information comprises information such as a lock state of the configuration file, file version information, the size of the file, MD5 and the like. The cluster device acquires a lock of a certain file of the management device, and if other devices lock the configuration file, the configuration file is not allowed to be locked again. After a cluster device acquires a lock of a configuration file, operations such as modifying and uploading the configuration file can be performed. The cluster device can release the lock of the configuration file locked by the cluster device, and other cluster devices can modify, upload and the like the configuration file after releasing the lock. And automatically releasing the lock after the configuration file is successfully uploaded, wherein the version of the configuration file is +1. The management device notifies all devices in the cluster when the version of the configuration file changes, so that the devices in the cluster know that the new version exists. The cluster equipment downloads the configuration file of the corresponding version from the management equipment, and verifies the integrity of the configuration file according to the MD5 value provided by the management equipment.
The cluster equipment periodically acquires information of a certain file from the management equipment, compares the file version of the local configuration file with the file version of the management equipment, and sends a request to the management equipment to download the latest configuration file when the local configuration file is inconsistent with the file version of the management equipment. And after downloading, checking the integrity of the configuration file according to the MD5 value provided by the management equipment.
If the user wants to discard the newly modified configuration information, the user can find the configuration information of the previous version according to the version information of the file recorded in the management device and roll back the version. The management device can inquire the configuration information version of the cluster device and know the synchronization condition of the cluster device.
The specific implementation steps comprise:
(1) On the cluster management equipment, cluster equipment for constructing a cluster is selected through a management interface, and a cluster of reference equipment components which are synchronized for the first time is selected.
(2) The reference device obtains locks for all configuration files from the management device and uploads all configuration files stored locally to the management device.
(3) After uploading the configuration file, the reference device changes the version number of the corresponding configuration file on the management device and unlocks the file, and meanwhile, the information of the configuration file change, namely file synchronization information (including unique identification of the file, version information of the file and size of the file) is notified (a webservice request is sent to the cluster device).
(4) When the cluster equipment receives the file synchronization information, comparing the file synchronization information with a local file version, if the file synchronization information is inconsistent, requesting the latest configuration file from the management equipment, then applying the latest configuration file to the local, and updating the file version of the locally stored configuration file.
(5) An administrator can modify the configuration file of a certain cluster device at the management platform, and lock the corresponding configuration file after modification. The cluster device discovers that the configuration information of the cluster device is manually modified, automatically triggers an upload operation, uploads the modified configuration file to the management device, generates a new file version after the management device receives the modified configuration file, unlocks the configuration file and notifies other cluster devices to enable the other cluster devices to synchronize the configuration file.
(6) An administrator can modify the configuration file of a certain cluster device at the management platform, and the corresponding configuration file is not locked after modification. The cluster device discovers that the configuration file of the cluster device is modified to request the lock of the configuration file from the management device, the cluster device uploads the modified configuration file, the management device generates a new file version after receiving the modified configuration file, unlocks the configuration file and informs other cluster devices.
(7) The administrator can check the historical configuration information on the management platform, roll back the configuration file, change the version after the roll back, reset the lock state (the state comprises a locked state and an unlocked state, and the reset is changed into the unlocked state) of the configuration file and inform each cluster device.
(8) The cluster equipment periodically polls the file version information of the management equipment, compares the file version information with the file version of the corresponding configuration file stored locally after acquiring the file version information, downloads the update from the management equipment if inconsistent conditions occur, and prevents the cluster equipment from not updating due to failure notification of the management equipment when connection is not smooth.
(9) The management platform can inquire (the management device and the cluster device can communicate with each other, and the version of each file of the device can be inquired, and the provided interface can be a full-volume interface for returning all versions or a non-full-volume interface for inquiring the version of a certain file).
According to the embodiment of the invention, after the cluster is established, one reference device is selected, and other devices are synchronized by taking the reference device as a template, so that the consistency of the configuration information of each cluster device in the cluster can be ensured, and when the configuration file of the cluster device is subsequently modified, the modified configuration file is uploaded to the management device, and the other devices only need to be updated in the management device, so that the complexity of the configuration information consistency operation is greatly reduced. Since a large number of configuration files are not required to be manually modified for consistency, labor can be saved, and thus the workload of configuration information consistency operation can be reduced. The manual operation has a plurality of uncertainties, and the embodiment of the invention verifies the configuration file according to the file version information and the file verification information, so that the configuration information of each device is consistent, and the accuracy of the consistency operation of the configuration information is improved. By inquiring the content of the previous configuration file, the previous configuration file can be known, version change can be seen, misoperation is prevented, meanwhile, the file version of the configuration file of the cluster equipment can be seen, the synchronous condition of each equipment can be known, and the safety of the system is improved. When the configuration information of the equipment is wrong, the rollback of the configuration file can be conveniently carried out, and the flexibility of the system is improved. The configuration file is locked before uploading, so that the synchronous operation can be prevented from covering the data, and the accuracy of the data is improved.
