Delete the corresponding file of the delete list stored in several CDN servers.
Further, processor 1001 can call the CDN server data administrator stored in memory 1005, also
Execute following operation:
At least two CDN servers are stored with identical data if it exists, then obtain at least two CDN servers respectively
Residual memory space information；
Based on the respective residual memory space information, a residue is determined from least two CDN servers
The maximum CDN server of memory space.
It is the flow diagram of CDN server data managing method first embodiment of the present invention referring to Fig. 2, Fig. 2.
In one embodiment, CDN server data managing method includes:
Step S10, detection whether there is at least two in several CDN servers in same CDN server set
CDN server is stored with identical data；
CDN (Content Delivery Network, content distributing network) is to place node server everywhere in network
Quantity it is huge enough, be correspondingly arranged on CDN server set, CDN server collection for the Local DNS informations of different clients
It include several CDN servers in conjunction.The data of every CDN server are provided by source server.
In the present embodiment, in order to save the memory space of CDN server, need to detect in same CDN server set
In several CDN servers in be stored with identical data with the presence or absence of at least two CDN servers.For example, being in same
The CDN server of same CDN server set includes: CDN server 1, CDN server 2, CDN server 3, CDN server 4
And CDN server 5, then detect CDN server 1, CDN server 2, CDN server 3, CDN server 4 and CDN server
Identical data is stored with the presence or absence of at least two CDN servers in 5.
Step S20, at least two CDN servers are stored with identical data if it exists, then from least two CDN services
A maximum CDN server of residual memory space is determined in device；
In the present embodiment, described at least two CDN servers are stored with identical data if it exists, then from described at least two
Determine the step of a residual memory space maximum CDN server to include: at least two CDN clothes if it exists in CDN server
Business device is stored with identical data, then obtains the respective residual memory space information of at least two CDN servers；Based on described
Respective residual memory space information determines a maximum CDN of residual memory space from least two CDN servers
Server.
In the present embodiment, at least two CDN servers are stored with identical data, such as CDN server 2, CDN clothes if it exists
It is stored with identical data in business device 3 and CDN server 5, then obtains residual memory space information S1, CDN of CDN server 2
The residual memory space information S2 of the server 3 and residual memory space information S3 of CDN server 5.Then compare CDN service
Residual memory space information S1, the residual memory space information S2 of CDN server 3 and the residue of CDN server 5 of device 2 are deposited
Spatial information S3 is stored up, if S3 is maximum, the maximum CDN server of residual memory space is CDN server 5.
Step S30, by the identical data except the residual memory space is maximum from least two CDN servers
CDN server except other CDN servers on delete.
In the present embodiment, if being stored with identical data in CDN server 2, CDN server 3 and CDN server 5, and surplus
The remaining maximum CDN server of memory space is CDN server 5, then by identical data from CDN server 2 and CDN server 3
Upper deletion.
In the present embodiment, detection whether there is at least two in several CDN servers in same CDN server set
Platform CDN server is stored with identical data；At least two CDN servers are stored with identical data if it exists, then from it is described at least
A maximum CDN server of residual memory space is determined in two CDN servers；By the identical data from described at least two
It is deleted in other CDN servers in platform CDN server in addition to the maximum CDN server of the residual memory space.Pass through
The present embodiment, under the premise of not influencing normally to provide CDN service, the link storage pressure of CDN server ensure that CDN
The efficiency of server, and then ensure that the performance of CDN system.
Further, in one embodiment of CDN server data managing method of the present invention, before step S10, further includes:
Detection whether there is an at least CDN server in several CDN servers in same CDN server set
Residual memory space be less than preset threshold；
The residual memory space of at least one CDN server is less than preset threshold if it exists, thens follow the steps S10.
In the present embodiment, if there is an at least CDN in several CDN servers in same CDN server set
The residual memory space of server is less than preset threshold, then illustrates that the data volume of at least server storage is excessive, Ke Nengying
Server performance is rung, needs the server excessive to the data volume of storage to carry out data and deletes, therefore, execute step S10.
Further, in one embodiment of CDN server data managing method of the present invention, after step slo, further includes:
At least two CDN servers are stored with identical data if it does not exist, then are calculated by lru algorithm and generate deletion column
Table；
Delete the corresponding file of the delete list stored in several CDN servers.
In the present embodiment, at least two CDN servers are stored with identical data if it does not exist, then carry out by other means
Data are deleted.By analyzing access log, calculated using LRU (Least Recently Used, least recently used) algorithm
Which file least referenced, subsequent CDN server generates delete list, to delete the file of least referenced.
In addition, the embodiment of the present invention also proposes a kind of computer readable storage medium, the computer readable storage medium
On be stored with CDN server data administrator, realized when the CDN server data administrator is executed by processor as above
The step of CDN server data managing method each embodiment.
The specific embodiment of computer readable storage medium of the present invention is each with above-mentioned CDN server data managing method
