The user asked.The Fig. 2 shows the implementation process figure of the response method of distributed file server provided in an embodiment of the present invention, in detail
State as follows：
In S201, the file server requests that user terminal is sent are received.
In the present embodiment, when user needs to operate the file in distributed File System, it will to
Local file server sends file server requests.Wherein, this document service request includes but is not limited to following a kind of or at least
Two kinds of combinations：File download service request, file upload services request, Document Editing service request, file delete service request
Deng.
Alternatively, also include before S201：The log-on message that user sends is received, to judge whether the user is conjunction
The log-on message of method user, wherein user include user name and user cipher.Due to the response system of the distributed file server
System is generally used for managing the internal file of enterprise or mechanism, therefore its security and confidentiality requirement are higher, and user is being carried out
, it is necessary to carry out register before file server requests, so that it is determined that whether the user is legal.
Alternatively, in the present embodiment, file server requests are sent to local file by internal lan and taken by user
Business device.The response system of distributed file server will pass through internal office to improve the security of storage file between its equipment
Domain net is communicated.In this case, if user needs to send file server requests to its home server in public network,
The file server requests that public domain is sent can be received by the communication interface of local file server, and perform S202 correlation
Operation.
In S202, according to the service type asked in the file server requests, whether the service type is judged
For file-management services.
In the present embodiment, local file server will receive different classes of file server requests, illustratively, such as right
File data carries out the service request of structuring operation and the service request of unstructured operation is carried out to file data；Its
In, the service request of structuring operation includes but is not limited to：Newly-increased database request, partitions of database request, memory node are drawn
The service request for dividing request etc. to operate database overall structure；And the service request of unstructured operation, i.e. this implementation
Service type is the request of file-management services in example, by including as described in S201, such as file download request, file are uploaded
The service request that request etc. is managed in itself to file.
In the present embodiment, structure is carried out to the storage device in the region due to only having the user of one's respective area just to possess authority
Change operation, if therefore local file server judges what the service type of Client-initiated file server requests operated as structuring
Service request, then responded by home server；If conversely, the service type of this document service request takes for file management
Business, then its destination address might not point to local memory device, it would be desirable to further be judged.
In the present embodiment, if the service type for the file server requests that user sends is file-management services, perform
S203 associative operation；It is necessarily this if the service type for the file server requests that user sends is not file-management services
Ground file server requests, therefore the request will be responded by local file server.
In S203, if the service type is the file-management services, institute in the file server requests is judged
Whether the file server of request is the local file server.
In the present embodiment, if its service type of a certain file server requests is file-management services, this document service
By comprising the file server asked in request, carried out according to the file server of the request and local file server
Match somebody with somebody, whether determine the service request is local file service request.Therefore, if local file server is judging a certain file clothes
Business request is file-management services request, then extracts the file server specified in the service request, to determine that this document takes
Business request is that local file is operated or strange land file is operated.
In the present embodiment, if the request object of file server requests is local file server, local file service
Device is directly in response to this document service request；If the request object of file server requests not local file server, it is determined that should
The strange land file server that file server requests are specified, and perform S204 associative operation.
Alternatively, in the present embodiment, the response system of distributed file server will be each file server distribution one
Individual file area mark, i.e., local file server and strange land file server have its one-to-one file area mark
Know, the coverage for characterizing each file server.Illustratively, this document area identification can be distributed document clothes
The mark defined inside the response system of business, is such as named according to the geographical position of each file server, such as local file
Server is used for the enterprise document for managing South China, then this document area identification can be：South China subregion；Now, a certain strange land
File server is used for the enterprise document for managing East China, then this document area identification is accordingly：East China subregion.
Alternatively, in the present embodiment, memory node information, local file server will be included in this document service request
It will be matched according to the memory node information and the nodal information being connected with local file server, it is true according to matching result
Determine whether the file server that file server requests are asked is local file server.Correspondingly, in local file server
The corresponding relation list of each file server and memory node will be included, home server can be according to right in file server requests
The memory node information answered, inquires about the corresponding relation list, determines corresponding file server.
In S204, if the non-local file server of the file server asked in the file server requests,
Then the file server requests are sent to strange land file server by communication interface, so that the strange land file server rings
Answer the file server requests；Wherein, the strange land server is by the file server asked in the file server requests.
In the present embodiment, if the file server asked in file server requests not local file server,
Perform the operation of strange land file server requests.The strange land file server requests, which are operated, is specially：Local file server will pass through it
File server requests are sent to the corresponding file server of file server requests, the wherein communication interface is this by communication interface
The communication interface of ground file server and public network.Due to distributed File System in order to improve the peace of file in system
Quan Xing, will in system LAN set fire wall, therefore distributed File System in equipment will be unable to directly with
Public network is communicated.And in order to realize each region in strange land file access and operation, distributed File System
File server will be communicated by communication interface with the file server in other regions, it is achieved thereby that to other regions
File is conducted interviews and operated.
In the present embodiment, if the distributed File System is only comprising two file servers, home server
File server requests are forwarded directly to another file server；If the distributed File System is comprising more than two
File server, then local file server corresponding strange land server will be determined according to this document service request, then again will
This document service request is forwarded to the strange land server.
It should be noted that in the present embodiment, each file server in distributed File System passes through communication
Interface is interconnected.Specifically, each file server is interconnected by communication interface with public network, is needing data interaction
When, then corresponding connecting link is generated according to the corresponding network address.Wherein, distributed File System will be each file
Server sets corresponding domain names and the network address, in order to be generated by the domain names and the network address to logical
Letter link is simultaneously communicated.
Alternatively, in the present embodiment, in distributed File System the storage device of regional can be deployed in every
From region (Demilitarized Zone, DMZ), the DMZ is specially the network area set between LAN and public network,
That is meshwork buffering region.In this case, asked in the file server requests that home server can be sent according to user terminal
File server, determine corresponding DMZ regions, thus home server directly in the DMZ regions storage device carry out
Operation, without carrying out service response by strange land file server again.Illustratively, if user needs the storage to strange land region
Transmitting file in equipment, then local file server directly will be deposited after this document service request is received with the strange land region
DMZ where storage equipment is communicated, and user file to be uploaded is deposited in the storage device, and can not take this
Business request is transmitted to strange land server, and the upload operation is performed by strange land server.
Illustratively, the distributed File System is file connection server system (LinkAPP File
Service System, LFS system).User logs in LFS systems in its terminal device, and local to its by the LFS systems
Server sends file server requests, and home server will perform S201 to S204 phase after this document service request is received
Operation is closed, so as to respond the Client-initiated file server requests.It can be seen that, in the present embodiment, user passes through in software layer
Log in LFS systems, the file in regional can will be operated, i.e., between regional for the angle of software layer,
It is intercommunication.
Above as can be seen that a kind of response method of distributed file server provided in an embodiment of the present invention is by setting up this
Ground file server and strange land file server, are responded to Client-initiated service request, and user is no longer directly right
Local memory device in distributed File System is operated, but file server requests are sent into local file clothes
Business device, local file server is defined as local operation still according to the file server asked in this document service request
Strange land is operated, and then transfers to strange land file server to respond by communication interface for strange land operation, it is achieved thereby that to different
The purpose that ground file is operated, managed.On the other hand, the storage device of bottom is not communicated directly with network, but
Data access is carried out by corresponding local file server and strange land unit, distributed File System is improved
Security.
