The method providing in order more clearly to set forth above-described embodiment one, in conjunction with foregoing, the content of following embodiment bis-and embodiment tri-of next take is example, and the method for cluster restructuring is carried out to detailed illustrating, and refers to following embodiment bis-and embodiment tri-:
Embodiment bis-
The present embodiment provides a kind of method of cluster restructuring, for convenience of explanation, the present embodiment be take node a existing host node in current cluster, node b be current cluster to be added pulled node, clustered software is that high available HA software is example, and the method that the present embodiment is provided is illustrated.Referring to Fig. 2, the concrete steps of the method that the present embodiment provides comprise:
201: the HA software startup on node a, set up a cluster that comprises node a;
For this step, the present embodiment only be take current cluster, and only to have a node a be example, and the HA software startup on node a is set up the mode of a node cluster can pass through existing techniques in realizing, repeats no more herein.In practical application, a cluster can also comprise a plurality of nodes, the situation that comprises a plurality of nodes for cluster, using a node in a plurality of nodes in current cluster as DC (Designated Co-ordinator, the coordinator of appointment) host node, clustered software state on other nodes need to be synchronizeed with this host node, and about the selection principle of host node, the present embodiment is not specifically limited.
202: automatically identify and in LAN (Local Area Network), meet the node b that adds current cluster, and on current visualization interface, show the icon of node b;
Particularly, the present embodiment does not limit meeting the mode of the node b that adds current cluster in identification LAN (Local Area Network), equally not to showing that on current visualization interface the icon mode of node b limits.In practical application, the icon of each node has corresponding to the figure entitling of node separately, therefore, can show with the mode of node name the icon of node b.For there being a plurality of situations that meet the node that adds current cluster, each node icon can be presented on current visualization interface by ordered arrangement, its put in order can have multiple, such as sorting by modes such as distance, title or times, to this, the present embodiment is not specifically limited.
In addition, except show the icon of node b on visualization interface, also show the icon of existing node in cluster, so that follow-up, by visualized operation, realize cluster and recombinate.
203: detect user to the drag motions of the icon of node b after, the distance between the icon of computing node b and the icon of node a;
For this step, why detect the drag motions of user to node b, for the drag motions of node b being determined to user's operation is intended to by user, due on current visualization interface except showing the existing node of current cluster, the icon that has also shown node b to be added, can obtain thus the range information between each node icon on visualization interface, when user pulls the icon of node b, the positional information between the icon of other nodes that show on the icon of node b and visualization interface also changes thereupon.In user's operating aspect, if user wishes node b to add current cluster, only need the node a that the icon of node b is approached to current cluster by drag motions to trigger cluster reorganization operation.To this, user can have multiple to the drag operation mode of the icon of node b, and such as pull the icon of node b with mouse move operation or touch screen move operation etc., the mode that the present embodiment does not pull node b to user limits.
In order to determine that user adds node the operation intention of cluster, the method that the present embodiment provides detect user to the drag motions of the icon of node b after, distance between the icon of the icon of computing node b and node a, thus according to the distance calculating, determine whether node b to add current cluster.
About detecting the mode of drag motions and the mode of calculating distance, all can realize by existing detection technique and account form, the present embodiment is not specifically limited this.It should be noted that, when current cluster has a plurality of existing node, the value of range information has multiple, such as getting in node b icon and current cluster the minimum value of distance between all node icons, or get the distance between node b icon and host node icon, the adjust the distance value mode of information of the present embodiment is not specifically limited.
204: whether the distance that judgement calculates is less than or equal to predetermined threshold value, if so, performs step 205, otherwise, execution step 206;
Wherein, after the icon of node b is pulled, current visualization interface can be as shown in Figure 3, after if user pulls the icon of node b, distance between the icon of the icon of node b and node a is less than predetermined threshold value, it is the interface scope that the icon of node b falls into node a place cluster, can further determine that user wishes node b to add ingress a place cluster, to this, for whether the icon of clear and definite node b falls into current cluster wide after being pulled, whether the distance that needs judgement to calculate is less than or equal to predetermined threshold value.The present embodiment does not limit the concrete size of predetermined threshold value, for example, predetermined threshold value is set to 2 centimetres, if on current visualization interface, distance between the icon of the icon of node b and node a is less than 2 centimetres, decision node b falls into current cluster wide, and the operation that can determine user's drag motions is intended that wishes node b to add current cluster.
In actual applications, after distance between decision node b icon and node a icon is less than or equal to predetermined threshold value, in order accurately to confirm user's operation intention, whether can also eject prompting frame prompting user confirms node b to add present node cluster, if user clicks confirmation, continue to perform step 205, otherwise execution step 206.The mode that ejects prompting frame can realize according to the mode of existing ejection prompting frame, certainly, can also select other modes to point out user, and the present embodiment is not specifically limited this.
205: the relation of whether having built up mutual trust between check-node b and node a, if so, perform step 208, otherwise, execution step 207;
For this step, distance between the icon of above-mentioned steps 204 decision node b and the icon of node a is less than or equal to predetermined threshold value, can determine that user is added after the operation intention of current cluster, judge between the node b that node a in cluster and user will add whether set up mutual trust relation.Wherein, the present embodiment does not limit the concrete mutual trust relation of setting up between node a and node b, for example, this mutual trust relation can be set up by password authentification, the method of whether setting up mutual trust relation between decision node a and node b can be password authentification, also can be other verification methods, to this, the embodiment of the present invention be not specifically limited.
206: by the icon correcting action of node b, flow process finishes;
Particularly, because the distance of judging between the icon of node b and the icon of node a is greater than predetermined threshold value, can judge that user is added current cluster to the operation of node b, therefore, default user abandons node b to add the operation of current cluster, thereby can be by the icon correcting action of node b.Certainly, for user, the icon of node b is pulled, and the situation that the icon of node b after pulling and the distance between the icon of node a are greater than predetermined threshold value, except taking the processing mode of the icon correcting action of node b, can also select other processing modes, for example, keep pulling position afterwards etc., the present embodiment is not specifically limited this.
207: prompting user input validation password, and input after correct authentication password user, set up the mutual trust relation between node b and node a;
For this step, during prompting user input validation password, can eject the mode of Password Input frame, prompting user input validation password, certainly, can also take other prompting modes, and the present embodiment does not limit this.If user cancels input, default user is cancelled the operation that node b is added to present node cluster, returns to step 206.
After user's input validation password, the authentication password of user input is mated with pre-stored correct authentication password to judge that whether the authentication password that user inputs is correct, if the authentication password of user's input is correct, set up the mutual trust relation between node b and node a and node b is added to present node cluster, if the authentication password mistake of user's input, point out user to re-enter, until input after correct authentication password, set up the mutual trust relation between node b and node a.
208: on detection node b, whether be deployed with HA software, and whether the version of this HA software is consistent with the version of the HA software of current cluster deploy, if not, performs step 209, if so, performs step 210;
Particularly, on detection node b, whether be deployed with HA software, and whether the version of the version of this HA software and the HA software of current cluster deploy is when consistent, on first decision node b, whether be deployed with HA software, if disposed HA software on node b, then judge that whether this HA software is consistent with the HA software version of current cluster deploy.
209: after the HA software of the current cluster deploy of node b deploy, start the HA software of disposing, and revise after the HA software relevant configuration of node b on node b, the current state information of current cluster is synchronized to node b, flow process finishes.
For this step, no matter be on node b, not dispose HA software, or disposed HA software at node b, but the version of the HA software of the version of this HA software and current cluster deploy is inconsistent, in order to realize the synchronous of cluster interior nodes, all need to be at the HA software of the current cluster deploy of node b deploy.For example, all installation kits of the HA software on node a are synchronized on node b and are installed, while specifically installing, RPM (RedHat Package Manager, RedHat software package management tool) bag deployment way is similar with adopting, and repeats no more herein.After the HA software of the current cluster deploy of node b deploy, revise again the HA software relevant configuration on node b, and current cluster state information is synchronized to node b, complete the consistency operation that node b is added to current cluster, the picture mark position of node b on visualization interface also moves in the scope of node a place cluster thereupon simultaneously, so far, add the operating process of current cluster to finish node b.
Wherein, revise the HA software relevant configuration on node b, include but not limited to revise the HA configuration file on node b, make it to meet the node configuration requirement of current cluster, the present embodiment does not limit the revised context of HA software relevant configuration.
210: revise the HA software relevant configuration of node b, and the current state information of current cluster is synchronized to node b, flow process finishes.
Particularly, if be deployed with HA software on node b, and the version of this HA software is consistent with the version of the HA software of current cluster deploy, node b is being added after current cluster, directly revise the HA relevant configuration on node b, more current cluster state information is synchronized to node b.And while having a plurality of node in current cluster, the HA software installation kit of host node can be synchronized to node b, the position of node b icon moves in current cluster wide simultaneously.Wherein, revise the HA software relevant configuration on node b, include but not limited to revise the HA configuration file on node b, make it to meet the node configuration requirement of current cluster, the present embodiment does not limit the revised context of HA software relevant configuration.
As such scheme preferably, the node having configured in node cluster, existing nodal information record in cluster configuration file, after system is restarted next time, can give tacit consent to and join in this node cluster, and not need above-mentioned checking mutual trust relationship step directly to add when the node of existing information recording adds cluster next time in cluster configuration file.
In addition, it should be noted that, in the method that the present embodiment provides, user can once move a node icon, also can once move a plurality of icons, and concrete grammar and mobile individual node are similar, and this embodiment of the present invention is no longer repeated.
Embodiment of the present invention supplying method, by meeting and add the node of condition and be presented on visualization interface in automatic identification LAN (Local Area Network), the drag motions Direct Recognition operation intention of user on visualization interface according to user again, then automatically complete the operation that adds ingress, reach simplification node and add fashionable complicated processes, improve the object of the efficiency of cluster restructuring; , by accepting user at visualization interface, operate meanwhile, increased mutual with user, and then the way to manage of another clustered node is provided, the user that not only can improve cluster management interface experiences, and also can reduce the maintenance cost of cluster.
Embodiment tri-
The present embodiment provides a kind of method of cluster restructuring, for convenience of explanation, the present embodiment is on the basis of above-described embodiment two, take and from current cluster, remove node b as example, the method that the present embodiment is provided is elaborated, referring to Fig. 4, the concrete steps of the method that the present embodiment provides comprise:
401: detect user to the drag motions of node b after, the distance in the icon of computing node b and current cluster between the icon of arbitrary node;
Similar with the step 203 in embodiment bis-, when user pulls the icon of node b, the positional information between the icon of other nodes that show on the icon of node b and visualization interface also changes thereupon.Accordingly, if user wishes node b to remove from present node cluster, also only need, by drag motions, the icon of node b is triggered to cluster reorganization operation away from the node of current cluster.Same, user can have multiple to the drag operation mode of the icon of node b, and such as pull the icon of node b with mouse move operation or touch screen move operation etc., the mode that the present embodiment does not pull node b to user limits.
For the operation intention of determining that user removes node from cluster, the method that the present embodiment provides detect user to the drag motions of the icon of node b after, distance between the icon of the arbitrary node in the icon of computing node b and current cluster, thus according to the distance calculating, determine whether node b to remove from current cluster.
Same, similar with embodiment bis-steps 203, about detecting the mode of drag motions and the mode of calculating distance, all can realize by existing detection technique and account form, the present embodiment is not specifically limited this.It should be noted that, when present node cluster has a plurality of node, the value of range information has multiple, such as getting in node b icon and current cluster the minimum value of distance between all node icons, or get the distance between node b icon and host node a icon, the adjust the distance value mode of information of the present embodiment is not specifically limited.
402: whether the distance in the icon of decision node b and current cluster between the icon of arbitrary node is greater than predetermined threshold value, if so, performs step 403, otherwise, execution step 404;
Wherein, after the icon of node b is pulled, current visualization interface can be as shown in Figure 5, after if user pulls the icon of node b, distance between the icon of the icon of node b and node a is greater than predetermined threshold value, it is the interface scope that the icon of node b shifts out node a place cluster, can further determine that user wishes node b to remove from node a place node cluster, to this, for whether the icon of clear and definite node b shifts out current cluster wide after being pulled, whether the distance that needs judgement to calculate is greater than predetermined threshold value.The present embodiment does not limit the concrete size of predetermined threshold value, for example, predetermined threshold value is set to 2 centimetres, if on current visualization interface, distance between the icon of the icon of node b and node a is greater than 2 centimetres, decision node b shifts out current cluster wide, and the operation that can determine user's drag motions is intended that wishes node b to remove from current cluster.
In actual applications, after distance between decision node b icon and node a icon is greater than predetermined threshold value, in order accurately to confirm user's operation intention, whether can also eject prompting frame prompting user confirms node b to remove from present node cluster, if user clicks confirmation, continue to perform step 403, otherwise execution step 404.The mode that ejects prompting frame can realize according to the mode of existing ejection prompting frame, certainly, can also select other modes to point out user, and the present embodiment is not specifically limited this.
403: node b is removed from current cluster, and the HA software of the upper operation of Stop node b, the application of the upper operation of node b is switched on the existing node of current cluster, flow process finishes.
Will be by node b from current cluster removes definite user, in order not affect the application moving on node b, in the clustered software moving on Stop node b, take over the application moving on node b, and application is switched on the existing node of current cluster to operation with the operation that removes of complete paired node b.
In cluster, except node a and b, while also having other nodes, the application from node b upper connecting tube can be switched to node a, also application can be switched on other nodes, the present embodiment is not specifically limited this.
404: by the icon correcting action of node b, flow process finishes.
Particularly, similar with embodiment bis-, because the distance of judging between the icon of arbitrary node in the icon of node b and current cluster is less than or equal to predetermined threshold value, can judge that user is not that it is removed from current cluster to the operation of node b, therefore, default user is abandoned the operation that node b is removed from current cluster, thereby can be by the icon correcting action of node b.Same, for user, the icon of node b is pulled, and the distance in the icon of the node b after pulling and current cluster between the icon of arbitrary node is less than or equal to the situation of predetermined threshold value, except taking the processing mode of the icon correcting action of node b, can also select other processing modes, for example, keep pulling position afterwards etc., the present embodiment is not specifically limited this.
The present embodiment supplying method, by Direct Recognition operation intention of user on visualization interface, completes the operation that removes node then automatically, reaches the complicated processes when simplifying node and removing, and improves the object of the efficiency of cluster restructuring; , by directly accept user on visualization interface, operate meanwhile, increased mutual with user, and then the way to manage of another clustered node is provided, the user that not only can improve cluster management interface experiences, and also can reduce the maintenance cost of cluster.
