Fig. 1 shows deletion server from the server cluster for providing cloud service according to an embodiment of the invention
The schematic flow sheet of method.As shown in figure 1, the method includes：
Step S110, creates an information list.
Step S120, by the mark of the service associated by each server identification information and each server in server cluster
Information is correspondingly saved in information list.
Each server in server cluster has unique identification information, and all services in server cluster
There is unique identification information, letter is stored in by corresponding with the identification information of the service which provides for the identification information of each server
In breath list, then when being inquired about, it is only necessary to search corresponding server identification information in information list, which is right
The identification information of the service that answers can also be found in information list.Here the associated clothes provided comprising server
Business, and the service that server is authorized to.For example, there are server A 1, A2, A3, the clothes that whole cluster is provided in server cluster
Business has B1, B2, B3, B4, and be associated with A1 is B1 and B3 services, and be associated with A2 is that B1 and B2 is serviced, related to A3
Connection is B3 and B4 services, then just preserve corresponding with B1, B3 for A1, A2 is corresponding with B1, B2 to be preserved, A3 is corresponding with B3, B4 to be protected
Depositing, in information list, a server being represented per a line, the mark letter of an associated service is preserved per string
Breath.
Step S130, when needing to delete a server in server cluster, inquires the clothes from information list
The identification information of the service associated by business device, determines each service of the server association.
When server deletion is carried out, in order to search the service being associated with server to be deleted, need to travel through
Service server phase whether to be deleted with this is searched in all services of whole server cluster, the relevant information the exterior and the interior of service
Association, if it is, determine associated；If it is not, then continuing to search for next service.
In this step, when needing to delete a server, do not needing to travel through all of service, as long as preserving
Service to be deleted is searched in the information list of the identification information of the service associated by each server identification information and each server
Device, the identification information of its associated service are also just obtained, and improve search efficiency.
Step S140, for each service of the server association, searches according to the identification information of the service for inquiring
To the information being associated with the server of the service, carry out deleting preparation process according to the information for associating.
In order to prevent server to be deleted from the service business of whole server cluster is affected after deleting, deleting the service
Before device, need to be deleted corresponding information in service associated there.So, related to the server finding
After the identification information of each service of connection, the identification information according to the service for inquiring find the service with the server
Associated information, the information according to association carry out deleting preparation process, and for example, deleting in the information of related service should
Attribute information of server etc..
Step S150, after all services for the server association all complete to delete preparation process, from server set
The server is deleted in group.
After completing all services of the server association to be deleted to preparation process, then the deletion behaviour for carrying out the server
Make, the impact that can thus avoid the deletion of the server from bringing the service business of whole server cluster.
It can be seen that, the present invention is when server deletion is carried out, it is not necessary to all services in traversal server cluster, leads to
Cross information list and can just find out the service being associated with server to be deleted, whole process is easy to use, time-consuming short, fortune
Row process occupancy resource is little, efficiency high.
If the mark by the service associated by each server identification information and each server in server cluster
Knowledge information is correspondingly saved in information list, then with being continuously increased for the associated service number of server, whole information
Quantity of information in list is constantly increasing.For example, represent a server per a line, each column representative server associated one
Individual service, then as the increase of service, the columns of information list are also constantly increasing, which may finally be caused to take
Memory space is larger, and the reduction of inquiry velocity.In order to solve this problem, in one embodiment of the invention, step
In S120 will be corresponding with the identification information of the service associated by each server for each server identification information in server cluster
Being saved in information list includes：
First, all services of each server association in server cluster are ranked up in a certain order and are obtained
Service ranking table.For example, the number of all services of each server association in server cluster is 5, then in order
Arrangement, can be B1, B2, B3, B4, B5.
Secondly, for server cluster in a server, according to service ranking table, successively with a binary numeral
Whether the labelling server is associated with a service, until last service of all services of each server association, i.e., according to
Secondary judge all of service whether associate with the server, will eventually get a binary digit string；Wherein, 1 association is represented,
0 expression is not associated.For example, for B1, B2, B3, B4, B5, the service being associated with server A 1 is B1, B3, then in storage
When, judge whether B1, B2, B3, B4, B5 are associated with server successively, associated be just labeled as " 1 ", unconnected just
" 0 " is labeled as, in this example, for A1, its binary digit string for obtaining is exactly 10100.
Finally, using the identification information of the service associated by binary digit string as the server and the mark of the server
Correspondingly it is saved in information list.So, in information list, finally there was only two column data, string is the mark letter of server
Breath, string is the identification information (string of binary characters) of the service being mutually associated with server.
When making a look up, it is only necessary to read the string of binary characters of the associated service of the server, by the binary system
Character string is corresponding with service ranking table, according to its association identification " 1 " or " 0 " judge corresponding service whether with the server phase
Association.
When being further added by a server or change service, the service according to increase or change is in service ranking table
Sorting position, increase or change corresponding labelling in string of binary characters.In the above example, for server A 1, increase
Plus the service of B5, then just by the 5th in the identification information " 10100 " of its associated service preserved in information list
" 0 " is changed into " 1 ", eventually becomes " 10101 "；Or B6 is serviced for server A 1 increases, then just by the guarantor in information list
The identification information of the associated service that deposits is changed to " 101001 ".
But, if in the case where quantity of service is huge, using string of binary characters as associated service mark
Knowledge information is preserved, and in its information list, the quantity of information of corresponding cell is also very huge, so, at one of the present invention
In embodiment, for server cluster in a server, said method further includes：By binary digit string in reverse order
The integer of a multi-system in addition to binary system is converted to after entering rearrangement；Using the service associated by integer as the server
Final identification information corresponding with the mark of the server be saved in information list.Here, the multi-system in addition to binary system
Can be decimal scale or hexadecimal.
By taking decimal scale as an example, for the identification information " 10100 " of the associated service of server A 1, weight is carried out in reverse order
It is changed into " 00101 " after row, after binary system turns metric conversion, " 00101 " is changed into " 5 ", then by " 5 " as the service
The final identification information of the service associated by device A1 is corresponding with the mark of the server to be saved in information list.
Here first the identification information of associated service is entered after rearrangement in reverse order being changed, is to reduce
The size of the integer after conversion, and in order to increase or change after associated service, the integer for obtaining is not too large.Example
Such as, in above-mentioned example, for the identification information " 10100 " of the associated service of server A 1, if not done by inverted order weight
Row, its integer for obtaining after decimal scale conversion be exactly " 20 " but. the integer obtained after carrying out inverted order rearrangement is " 5 "；Or
If after the whole server cluster of person increases service, for the identification information of the associated service of server A 1
" 10100100 ", reset if not done by inverted order, its integer for obtaining after decimal scale conversion be exactly " 164 " but. enter
Row inverted order is changed into the integer that " 00100101 " obtain after resetting be " 37 ", it is seen then that the integer that inverted order is obtained after retaking is less than not
Integer after inverted order rearrangement, particularly when the quantity of service is very big, this effect can become apparent from.
Because when being stored in the final identification information of the associated service of server, being to reset through inverted order, and entering more
System conversion, so need through reverse conversion when each service of the server association is determined according to information list.?
The mark for inquiring the service associated by the server from information list in one embodiment of the present of invention, in step S130
Information, determines that each service of the server association includes：The mark of the service associated by the server is inquired from information list
Knowledge information, is converted to binary digit string；The binary digit string being converted to is entered after rearrangement in reverse order, control service row
Sequence table determines each service of the server association.
An information list is created in step S110, can re-create a new list, or, using server set
The relationship server table that itself is present in group is created.So, in one embodiment of the invention, wound in step S110
Building an information list includes：Increase string in the relationship server table of server cluster, for preserving associated by each server
Service identification information；Wherein, the corresponding server of every a line of relationship server table, and deposited in relationship server table
Row in server identification information.
In the field of computer technology of reality, in order to obtain the space of the internal memory actual size more than physical machine, lead to
The method for creating virtual machine can be adopted often, it is suitable for the deletion action of virtual machine, so, in a reality of the present invention
Apply in example, server is the virtual machine created in physical machine；Deleting the server from server cluster includes：Destroy corresponding
Virtual machine.
Fig. 2 shows deletion server from the server cluster for providing cloud service according to an embodiment of the invention
The structural representation of device.As shown in Fig. 2 the device 200 that should delete server from the server cluster for providing cloud service is wrapped
Include：
Table creating unit 210, is suitable to create an information list；And each server identification letter just in server cluster
Breath is corresponding with the identification information of the service associated by each server to be saved in information list.
Each server in server cluster has unique identification information, and all services in server cluster
There is unique identification information, letter is stored in by corresponding with the identification information of the service which provides for the identification information of each server
In breath list, then when being inquired about, it is only necessary to search corresponding server identification information in information list, which is right
The identification information of the service that answers can also be found in information list.Here the associated clothes provided comprising server
Business, and the service that server is authorized to.For example, there are server A 1, A2, A3, the clothes that whole cluster is provided in server cluster
Business has B1, B2, B3, B4, and be associated with A1 is B1 and B3 services, and be associated with A2 is that B1 and B2 is serviced, related to A3
Connection is B3 and B4 services, then just preserve corresponding with B1, B3 for A1, A2 is corresponding with B1, B2 to be preserved, A3 is corresponding with B3, B4 to be protected
Depositing, in information list, a server being represented per a line, the mark letter of an associated service is preserved per string
Breath.
Delete and prepare processing unit 220, be suitable to, when needing to delete a server in server cluster, arrange from information
The identification information of the service associated by the server is inquired in table, determines each service of the server association；For the service
Each service of device association, the identification information according to the service for inquiring find being associated with the server for the service
Information, the information according to association carry out deleting preparation process.
When server deletion is carried out, in order to search the service being associated with server to be deleted, need to travel through
Service server phase whether to be deleted with this is searched in all services of whole server cluster, the relevant information the exterior and the interior of service
Association, if it is, determine associated；If it is not, then continuing to search for next service.
In this unit, when needing to delete a server, do not needing to travel through all of service, as long as preserving
Service to be deleted is searched in the information list of the identification information of the service associated by each server identification information and each server
Device, the identification information of its associated service are also just obtained, and improve search efficiency.
In order to prevent server to be deleted from the service business of whole server cluster is affected after deleting, deleting the service
Before device, need to be deleted corresponding information in service associated there.So, related to the server finding
After the identification information of each service of connection, the identification information according to the service for inquiring find the service with the server
Associated information, the information according to association carry out deleting preparation process, and for example, deleting in the information of related service should
Attribute information of server etc..
Unit 230 is deleted, is suitable to after all services for the server association all complete to delete preparation process, from clothes
The server is deleted in business device cluster.
After completing all services of the server association to be deleted to preparation process, then the deletion behaviour for carrying out the server
Make, the impact that can thus avoid the deletion of the server from bringing the service business of whole server cluster.
It can be seen that, the present invention is when server deletion is carried out, it is not necessary to all services in traversal server cluster, leads to
Cross information list and can just find out the service being associated with server to be deleted, whole process is easy to use, time-consuming short, fortune
Row process occupancy resource is little, efficiency high.
If the mark by the service associated by each server identification information and each server in server cluster
Knowledge information is correspondingly saved in information list, then with being continuously increased for the associated service number of server, whole information
Quantity of information in list is constantly increasing.For example, represent a server per a line, each column representative server associated one
Individual service, then as the increase of service, the columns of information list are also constantly increasing, which may finally be caused to take
Memory space is larger, and the reduction of inquiry velocity.In order to solve this problem, in one embodiment of the invention, table wound
Unit 210 is built, is suitable to：
First, all services of each server association in server cluster are ranked up in a certain order and are obtained
Service ranking table.For example, the number of all services of each server association in server cluster is 5, then in order
Arrangement, can be B1, B2, B3, B4, B5.
Secondly, for server cluster in a server, according to service ranking table, successively with a binary numeral
Whether the labelling server is associated with a service, until last service of all services of each server association, is obtained
One binary digit string；Wherein, 1 represent that association, 0 expression are not associated；For example, for B1, B2, B3, B4, B5, with server
The associated services of A1 are B1, B3, then when storage, judge whether B1, B2, B3, B4, B5 are related to server successively
Connection, associated be just labeled as " 1 ", unconnected be just labeled as " 0 ", in this example, for A1, its binary digit string for obtaining
It is exactly 10100.
Finally, using the identification information of the service associated by binary digit string as the server and the mark of the server
Correspondingly it is saved in information list.So, in information list, finally there was only two column data, string is the mark letter of server
Breath, string is the identification information (string of binary characters) of the service being mutually associated with server.
When making a look up, it is only necessary to read the string of binary characters of the associated service of the server, by the binary system
Character string is corresponding with service ranking table, according to its association identification " 1 " or " 0 " judge corresponding service whether with the server phase
Association.
When being further added by a server or change service, the service according to increase or change is in service ranking table
Sorting position, increase or change corresponding labelling in string of binary characters.In the above example, for server A 1, increase
Plus the service of B5, then just by the 5th in the identification information " 10100 " of its associated service preserved in information list
" 0 " is changed into " 1 ", eventually becomes " 10101 "；Or B6 is serviced for server A 1 increases, then just by the guarantor in information list
The identification information of the associated service that deposits is changed to " 101001 ".
But, if in the case where quantity of service is huge, using string of binary characters as associated service mark
Knowledge information is preserved, and in its information list, the quantity of information of corresponding cell is also very huge, so, at one of the present invention
In embodiment, table creating unit 210, in being further adapted for for server cluster a server, by binary digit string
