s201, responding to the request of cleaning the server, and selecting the server from the plurality of servers to clean the file.
In an embodiment of the invention, the trigger to clean the server is triggered by a request from the clean server. As one example, a request to clean the server is received through a preset script or a preset server.
In response to a request to clean a server, a server may be selected from a plurality of servers to thereby enable cleaning of the selected server. As one example, a periodic clean-up server is implemented as requested by the clean-up server.
S202, in the selected server, the server file directory is determined based on the request of the cleaning server.
The server has a plurality of file directories, each of which stores a plurality of files. In the selected server, a server file directory is determined in accordance with a request to clean the server. The files in the determined server file directory belong to files needing to be cleaned.
And S203, storing the server files in the server file directory into a preset file directory in the running process of the server.
During the operation of the server, the server generates a scene server file. Wherein the server file comprises one or more of the following files: the method comprises the steps of logging files, generating non-logging files by a server and receiving files by the server. The server files are typically stored in a server file directory.
Therefore, the server files in the server file directory can be stored in the preset file directory during the operation of the server, so that the files can be cleaned.
In the embodiment of fig. 2, in response to a request for cleaning a server, a server and a server file directory in the server are selected to store a server file to be cleaned in a preset file directory.
In an embodiment of the present invention, in consideration of a large number of server files in a server, a preset file directory may be set in each server, and then the server files of the server are stored in the preset file directory of the server. That is, a preset file directory is provided in each server.
In a server cluster of the system, a preset file directory is provided in one or more servers of a plurality of servers. That is, the predetermined file directories are centrally located in one or more servers, and thus centrally store the server files.
In one embodiment of the invention, it is contemplated that the server file includes one or more of the following files: the method comprises the steps of logging files, generating non-logging files by a server and receiving files by the server. The server files may also be stored separately according to the kind of the server files.
In the case where the server file includes a log file, the server file may be stored in a preset file directory of the server in order to facilitate query of the log file. That is, the server file includes a log file, and the server files in the running process of the plurality of servers are stored in a preset file directory of the server to which the server files belong.
In the case where the server file includes a server-generated non-log file and a server-received file, the server file may also be stored in a preset file directory shared by a plurality of servers, thereby facilitating the cleaning of the file. The server file comprises a server generation non-log file and a server receiving file, and the server files in the operation process of a plurality of servers are stored in a preset file directory shared by one server in the plurality of servers.
In an embodiment of the present invention, the preset file directory is disposed in the memory, so as to facilitate the file cleaning under the condition that the server operates normally.
S102, screening out invalid files in a preset file directory based on the generation date of the server files and the file cleaning parameters.
Server files are stored in the preset file directory, and for each server file, not every server file is an invalid file. The invalid file needs to be screened out based on the generation date of the server file and the parameters of the cleaning file. The generation date of the server file is the creation date of the server file. The clean file parameter is a pre-parameter.
Referring to fig. 3, fig. 3 is a schematic diagram of a process 300 for screening out invalid files based on the generation date of the server file and the parameters of the clean file according to an embodiment of the present invention. The method specifically comprises the following steps:

In the embodiment of the invention, the file cleaning parameters comprise a period, and invalid files are screened out by combining the generation date of the server files. Such as: and if the generation date of the server file is within the period, the server file is taken as an invalid file. As an example, the period is set to: and 7 days, namely cleaning the server files 7 days ago. The server file whose generation date is within 7 days does not belong to the invalid file. As an example, the period is set to one or more of the following parameters: 7 days, 10 days, 15 days, 30 days, 60 days, 90 days and 180 days.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating a process 400 for screening out invalid files according to a generation date of a server file according to an embodiment of the present invention. The method specifically comprises the following steps:

And responding to the cleaning file parameter setting request, and setting a default period and a time point interval period in the cleaning file parameters.
The default period in the clean-up file parameter is a default period of time from the current time. The time point interval period is a preset time period from the present.
S402, updating the default period according to the preset time point and the time point interval period.
The default period is a parameter for screening out invalid files. In the embodiment of the present invention, the default period may be updated. Specifically, the default period is updated according to the preset time point and the time point interval period. And at a preset time point, if the original default period cannot meet the requirement of clearing the file, updating the default period at a time interval period. That is, the time point interval period is used as the default period.
As an example, the default period is 60 days. And when the server normally operates, taking the server files more than 60 days away from the current time as invalid files in combination with the generation date of the server files. In a preset time period, the preset time point comprises: the peak days of online shopping and the holidays of major festivals. The time point interval period was set to 90 days. In this way, the server file retention period is increased by updating the default period.
And S403, screening out invalid files according to the generation date of the server file in the updated default period.
Based on the updated default period, in combination with the generation date of the server file, invalid files can be screened out. As an example, if the updated default period is 90 days, then the server files that are 90 days away from the current time will be considered invalid.
In the embodiment of fig. 4, the main function of the cleaning file parameter is to directly modify the cleaning file parameter without modifying the written configuration file when the default period changes, so as to meet the requirements of different periods and important time points. And updating the default period based on the time point interval period so as to be suitable for the actual use condition of the server.
