Problems solved by technology

[0005] First of all, the node joining process needs to manually modify the configuration file and verify the authority every time. The process is cumbersome and the degree of automation is low. Especially when many new nodes are required to join, the problem of low efficiency is prominent; secondly, when joining nodes through the operation on the interface , requires multi-step operations, the configuration process is not efficient and intuitive enough, and the user experience is poor; in addition, the cumbersome process has higher requirements for cluster administrators, which indirectly increases the maintenance cost of the cluster, and the market competitiveness of the software has not been fully demonstrated

Embodiment 1

[0031] This embodiment provides a method for cluster reorganization, see figure 1 , the specific steps of the method provided in this embodiment include:

[0032] 101: Identify all valid nodes in the local area network that are eligible to join the current cluster, and display the icons of all identified valid nodes on the current visualization interface;

[0033] 102: Add the dragged node to the current cluster according to the user's dragging action on the icon of any node among all the displayed valid nodes.

[0034] Among them, the current visualization interface also displays the icons of existing nodes in the current cluster. According to the user's drag action on the icon of any node among all the displayed valid nodes, the dragged node will be added to the current cluster, specifically including:

[0035] After detecting the user's drag action on the icon of any node among all valid nodes displayed, calculate the distance between the icon of the dragged node and the i...

Embodiment 2

[0062] In order to more clearly illustrate the method provided by the above-mentioned embodiment 1, combined with the above-mentioned content, next, take the content of the following embodiment 2 and embodiment 3 as examples to illustrate the cluster reorganization method in detail, see the following embodiment 2 for details and Example Three:

[0063] Embodiment two

[0064] This embodiment provides a method for cluster reorganization. For the sake of illustration, this embodiment takes node a as the existing master node in the current cluster, node b as the dragged node to be added to the current cluster, and the cluster software as high availability The HA software is taken as an example to illustrate the method provided in this embodiment. see figure 2 , the specific steps of the method provided in this embodiment include:

[0065] 201: The HA software on node a is started, and a cluster including node a is established;

[0066] For this step, this embodiment only tak...

Embodiment 3

[0095] This embodiment provides a method for cluster reorganization. For the convenience of description, this embodiment is based on the above-mentioned embodiment 2, and takes removing node b from the current cluster as an example to describe the method provided in this embodiment in detail. see Figure 4 , the specific steps of the method provided in this embodiment include:

[0096] 401: After detecting the user's drag action on node b, calculate the distance between the icon of node b and the icon of any node in the current cluster;

[0097] Similar to step 203 in the second embodiment, when the user drags the icon of node b, the position information between the icon of node b and icons of other nodes displayed on the visual interface also changes accordingly. Correspondingly, if the user wants to remove node b from the current node cluster, it only needs to drag the icon of node b away from the nodes of the current cluster to trigger the cluster reorganization operation....

Abstract

The invention discloses a method and device for cluster recombination, and belongs to the field of computers. The method includes firstly, recognizing all effective nodes meeting requirements for being added to a current cluster in a local area network, and displaying icons of all effective recognized nodes on a current visualized interface; and secondly, adding a dragged node to the current cluster according to dragging action of an icon of any node in all displayed effective nodes by a user. Nodes qualified to be added in the local area network can be automatically recognized and displayed on the visualized interface, operation intention of the user can be recognized directly according to the visualized interface, and further operation of the nodes can be achieved automatically, so that the complicated process of being added to the cluster of the nodes can be simplified, and efficiency of cluster recombination can be improved. In addition, user operation can be accepted directly through the visualized interface, interaction with the user can be increased, another management manner of cluster nodes is provided, so that user experience of a cluster management interface is improved, and maintenance cost of the cluster is reduced.

Description

technical field [0001] The invention relates to the field of computers, in particular to a cluster reorganization method and device. Background technique [0002] In the computer field, there is a kind of HA (High Availability, high availability) software, which improves the availability of systems and applications by minimizing the downtime caused by routine maintenance operations (planned) and sudden system crashes (unplanned). ; while the HA software is installed and configured on the cluster nodes, so that each node coordinates at the same time. The process of adding or removing nodes in the node cluster is called cluster reorganization. Cluster deployment can effectively improve the availability of the system. The continuous development of cluster reorganization is becoming more and more widely used. [0003] In the existing cluster reorganization method, taking adding a new node as an example, the user first modifies the underlying communication configuration file of ...
