Embodiment 1

[0055] The following introduces Embodiment 1 of a processing method for a file access request provided by the present invention. Embodiment 1 is implemented based on the ganesha-nfs business process running on the nfs server, see figure 1 , Embodiment 1 specifically includes:

[0056] Step S101: Set a processing cycle in advance, and initialize the number of processed requests at the beginning of the processing cycle.

[0057] Step S102: Receive the file access request sent by the current nfs client.

[0058] Step S103: Determine whether the number of processed requests in the current processing cycle reaches a preset threshold.

[0059] Step S104: discarding the file access request if the number of processed requests reaches a preset threshold.

[0060] Step S105: If the number of processed requests does not reach the preset threshold, add the file access request to a request processing queue, and update the number of processed requests.

[0061] It can be seen that the pr...

Embodiment 2

[0063] see figure 2 , embodiment two specifically includes:

[0064] Step S201: Set a processing cycle in advance, and initialize the number of processed requests for the current nfs client at the beginning of the processing cycle.

[0065] Step S202: Receive the file access request sent by the current nfs client.

[0066] Step S203: judging whether the number of processed requests for the current nfs client in the current processing cycle reaches a preset threshold.

[0067] Step S204: If the number of processed requests for the current nfs client reaches a preset threshold, discard the file access request.

[0068] Step S205: If the number of processed requests for the current nfs client does not reach the preset threshold, add the file access request to a request processing queue, and update the number of processed requests.

[0069] It can be seen that the processing method of a file access request provided in this embodiment mainly limits the number of processed file ...

Embodiment 3

[0070] see image 3 , Embodiment three specifically includes:

[0071] Step S301: Set a processing cycle in advance, and initialize the number of processed requests for multiple nfs clients at the beginning of the processing cycle.

[0072] Step S302: Receive the file access request sent by the current nfs client.

[0073] Step S303: judging whether the number of processed requests for multiple nfs clients in the current processing cycle reaches a preset threshold.

[0074] Step S304: If the number of processed requests for multiple nfs clients reaches a preset threshold, discard the file access request.

[0075] Step S305: If the number of processed requests for multiple nfs clients does not reach the preset threshold, add the file access request to a request processing queue, and update the number of processed requests.

Abstract

The invention discloses a file access request processing method, which is implemented based on the ganesha-nfs business process running on the nfs server end, and can initialize the number of processed requests at the beginning of the processing cycle, and after receiving the file access request sent by the current nfs client , to determine whether the number of processed requests in the current processing cycle reaches the preset threshold, if so, discard the file access request, otherwise add the file access request to the request processing queue, and update the number of processed requests. It can be seen that this method can limit the number of file access requests processed by the server in one processing cycle, avoid system crashes caused by centralized processing of a large number of file access requests in a certain period of time, and also limit a large number of malicious file access requests, improving security sex. In addition, the present invention also provides a file access request processing device, an nfs server, and an nfs system, the function of which is corresponding to the above method.

Description

technical field [0001] The invention relates to the computer field, in particular to a file access request processing method, device, nfs server, and nfs system. Background technique [0002] NFS is a very widely used file sharing protocol in the Linux environment. Through this protocol, the NFS client can easily access the shared files located on the NFS server. [0003] Among them, ganesha-nfs is a very easy-to-use application software using this protocol. Ganesha-nfs running on the nfs server can handle file access requests from nfs clients, but because the number of file access requests from nfs clients cannot be counted , may bring many security problems. For example, first, the number of requests processed by the nfs server in a certain period of time is too large and too concentrated, which may cause the nfs server to crash; second, when the file access request processing volume of each nfs client When the difference is large, it may cause low performance of the nfs ...
