Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this Embodiment in invention, for those of ordinary skill in the art under the premise of creative work is not made, what is obtained is every other Embodiment, belong to the scope of the present invention.
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description The present invention is described in further detail.
Next, a kind of method for the self-defined distribution virtual IP addresses of CTDB that the embodiment of the present invention is provided is discussed in detail.Fig. 1 For a kind of flow chart of the method for the self-defined distribution virtual IP addresses of CTDB provided in an embodiment of the present invention, this method includes：
S101：The virtual IP address allocation strategy file prestored is read, and the virtual IP address allocation strategy file is loaded Into internal memory.
In embodiments of the present invention, user according to actual use scene, can formulate the allocation strategy of corresponding virtual IP address, All allocation strategies can be stored in system with virtual IP address allocation strategy document form.
A plurality of allocation strategy can be included in the virtual IP address allocation strategy file, every allocation strategy includes one Virtual IP address and its corresponding node, and all nodes arrange according to priority orders corresponding to the virtual IP address.
In the specific implementation, the distribution priority of each node can be made for each virtual IP address, with the thing of node Node number arrangement is managed (since 0), the virtual IP address can be first allocated to the node of highest priority；When the node of highest priority When breaking down, the virtual IP address can be assigned to the node of highest priority in remaining node.
Virtual IP address allocation strategy file can use extensible markup language (Extensible Markup Language, XML) file carries out tissue and storage, the distribution priority of each node is made for each virtual IP address, node number is with comma Separate, its concrete form is as follows：
<Virtual_ips nodecount=" 3 " vipcount=" 3 ">
<Vip ip=" 10.0.0.1 ">0,1,2</vip>
<Vip ip=" 10.0.0.2 ">1,2,0</vip>
<Vip ip=" 10.0.0.3 ">2,0,1</vip>
</virtual_ips>
Wherein, nodecount represents the node number of cluster；Vipcount represents the number of virtual IP address, and address is 10.0.0.1 node sequence corresponding to virtual IP address is " 0,1,2 "；Address is node sequence corresponding to 10.0.0.2 virtual IP address For " 1,2,0 "；Address is that node sequence corresponding to 10.0.0.3 virtual IP address is " 2,0,1 ".
S102：An allocation strategy is obtained from the internal memory, the node that judging the allocation strategy successively includes is No failure, if in the presence of the node not broken down, the virtual IP address of the allocation strategy is assigned on the node；Directly To the distribution for completing virtual IP address in all allocation strategies, then end operation.
CTDB softwares can carry out the distribution of virtual IP address according to the allocation strategy of acquisition.It is false by taking an allocation strategy as an example If virtual IP address is corresponding with 5 nodes in this allocation strategy, node 1 is followed successively by node 5 according to priority orders, and system can be with Fault detect first is carried out to the node 1 of highest priority, when node 1 does not break down, then the virtual IP address can be assigned to On node 1, the distribution of the virtual IP address is completed；When 1 failure of node, then the node of highest priority is chosen from remaining node 2 carry out fault detect, when node 2 does not break down, then can be assigned to the virtual IP address on node 2；When the failure of node 2 When, then from remaining node choose highest priority node 3 carry out fault detect, the like complete virtual IP address point Match somebody with somebody.
By taking an allocation strategy as an example, when the node that presence is not broken down, then by the virtual IP address of the allocation strategy point It is fitted on the node, completes the distribution of the virtual IP address；Either when the failure for completing all nodes in this allocation strategy is sentenced Have no progeny, then next allocation strategy is handled, the processing mode of next allocation strategy and the processing of this allocation strategy Mode is similar, will not be repeated here.
A plurality of allocation strategy can be included in view of virtual IP address allocation strategy file, the virtual IP address in every allocation strategy Corresponding node can have it is multiple, in the specific implementation, can be by setting the side of allocation strategy count value and node counts value Formula, complete the distribution of virtual IP address, its detailed process as shown in Fig. 2 including：
S21：Initialize allocation strategy count value.
S22：An allocation strategy is obtained from the internal memory, and the allocation strategy count value is added 1.
Allocation strategy count value can be used to indicate that the bar number for the allocation strategy that system had obtained, can during initialization So that allocation strategy count value is arranged into 0, an allocation strategy is often read from internal memory, can be with corresponding to allocation strategy count value Add 1.
It should be noted that in order to avoid repeating, group system obtains from untreated allocation strategy every time Take an allocation strategy.In the specific implementation, group system can be according to the distribution plan that virtual IP address allocation strategy file includes Order slightly is successively read.
S23：Judge whether the allocation strategy count value is less than or equal to allocation strategy total value.
Allocation strategy total value can be the total number for the allocation strategy that virtual IP address allocation strategy file includes.
When allocation strategy count value is less than or equal to allocation strategy total value, then illustrate the virtual IP address in this allocation strategy It is also unassigned, then it can perform S24；When allocation strategy count value is more than allocation strategy total value, then illustrate virtual IP address point All allocation strategies included with strategy file have been disposed, now then end operation.
S24：Initialize node counts value.
S25：First node information is obtained from the allocation strategy, and the node counts value is added 1.
Node counts value can be used to indicate that the number of the node obtained, can be by node counts during initialization Value is arranged to 0, often obtains a nodal information, can add 1 corresponding to node counts value.
S26：Judge whether the node counts value is less than or equal to node total number value.
Node total number value can be the total number for the node that an allocation strategy includes.
When node counts value is less than or equal to node total number value, then illustrate also not sentence the failure situation of the node It is disconnected, then it can perform S27；When node counts value is more than node total number value, then illustrate to the institute in this allocation strategy There is node to carry out breakdown judge, now then end operation.
S27：Judge whether the first node breaks down.
By taking an allocation strategy as an example, first node can be that all failures that do not carry out included in this allocation strategy are sentenced A node of highest priority in disconnected node.
If first node breaks down, illustrate that the node can not provide business service, now need to next node Judged, that is, perform S28；If first node does not break down, illustrate that the node can provide business service, now can be with Virtual IP address is assigned on the node, that is, performs S29；
S28：According to the priority orders of the allocation strategy interior joint, will appear from failure the first node it is next Individual node is as new first node and returns to the S25.
S29：The virtual IP address of the allocation strategy is assigned on the first node, and returns to the S22.
The configuration of virtual IP address in an allocation strategy can be completed by performing a S24 to S29 operation, by returning to S22 The configuration of all allocation strategies can be sequentially completed.
The virtual IP address allocation strategy file of reading is loaded into internal memory by system it can be seen from above-mentioned technical proposal； Include a plurality of allocation strategy in the virtual IP address allocation strategy file, every allocation strategy includes a virtual IP address and its correspondingly Node, and all nodes arrange according to priority orders corresponding to virtual IP address；A distribution plan is obtained from the internal memory Slightly, whether the node that judging the allocation strategy successively includes breaks down, if in the presence of the node not broken down, by institute The virtual IP address for stating allocation strategy is assigned on the node；Until the distribution of virtual IP address in all allocation strategies is completed, then End operation.Allocation strategy in the virtual IP address allocation strategy file prestored in system can be by user according to actual use Scene, or the use habit of user determine, namely user can arbitrarily set the distribution of virtual IP address according to the needs of oneself Mode, rather than the distribution as the limited algorithm progress virtual IP address built in CTDB, substantially increase the flexibility of CTDB clusters. Simultaneously when group service goes wrong, user can solve according to virtual IP address and the corresponding relation of node, fast positioning node Problem；When needing to be bound virtual IP address and specific business when group service complexity, which user can also be apparent from Which business and service have been bound on a little virtual IP addresses, has improved the ease for use of cluster.
Node number corresponding to each virtual IP address is limited, it is possible that event all occur in all nodes corresponding to the virtual IP address The situation of barrier, now, the distribution of the virtual IP address can not be smoothly completed, for the ease of providing user in time, the distribution can be worked as When all nodes that strategy includes break down, then alarm prompt is carried out.
Fig. 3 is a kind of structural representation of the device of the self-defined distribution virtual IP addresses of CTDB provided in an embodiment of the present invention, is wrapped Include reading unit 31 and allocation unit 32；
The reading unit 31, divide for reading the virtual IP address allocation strategy file prestored, and by the virtual IP address It is loaded into strategy file in internal memory；Include a plurality of allocation strategy, every distribution plan in the virtual IP address allocation strategy file Slightly include a virtual IP address and its corresponding node, and all nodes are suitable according to priority corresponding to the virtual IP address Sequence arranges；
