Network mapping method and device for files

Abstract

The invention provides a network mapping method and device for files. The network mapping method for the files comprises the following steps: an FIFO_IN file is created in a source host, and a target host logs in to the source host through SSH; an FIFO_OUT file is created in the target host; the FIFO_IN file is redirected to the FIFO_OUT file through an SSH tunnel and a named pipe, so that a mapping relationship between the FIFO_IN file and the FIFO_OUT file is established; a source file or a source process output is written into the FIFO_IN file in the source host; the source file or the source process output is mapped from the FIFO_IN file to the FIFO_OUT file through the mapping relationship; and a target process in the target host reads the source file or the source process output from the FIFO_OUT file. The method and the device provided by the invention have the advantages that the security of cross-host file mapping and transmission can be improved; meanwhile, disk space is not occupied during actual transmission, and multiple processes can be executed at the same time, so that time consumption caused by disk accessing is reduced.

Description

technical field [0001] The present invention relates to data sharing technology, in particular to a file network mapping method and device. Background technique [0002] When processing files in the data center, it is often necessary to perform operations such as decompression, transmission and processing of a large number of compressed files (such as database backup, restoration, sharing, etc.). The traditional operation process needs to be carried out step by step, and the latter step needs to wait for the previous step to be implemented. Complete, otherwise the operation cannot be performed, and the process will take up a lot of disk space and is very time-consuming. [0003] In the existing file transfer technology, you can use NFS, Samba, etc. to realize cross-machine file sharing, but this method needs to deploy Server and Client programs, and requires root privileges to create and mount file systems, and most of them are plain text transfers, which are difficult Ensu...

[0002] When processing files in the data center, it is often necessary to perform operations such as decompression, transmission and processing of a large number of compressed files (such as database backup, restoration, sharing, etc.). The traditional operation process needs to be carried out step by step, and the latter step needs to wait for the previous step to be implemented. Complete, otherwise the operation cannot be performed, the process will take up a lot of disk space, and is very time-consuming

[0003] In the existing file transfer technology, you can use NFS, Samba, etc. to realize cross-machine file sharing, but this method needs to deploy Server and Client programs, and requires root privileges to create and mount file systems, and most of them are plain text transfers, which are difficult Ensure the security of file transfers

[0004] Alternatively, you can use sftp, ftp, etc. to transfer files across machines, and then perform subsequent processing, but these operations must be implemented serially, which will prolong the overall time, and will occupy disk space and network bandwidth resources during the process

[0005] Furthermore, file streams can be processed concurrently using the "anonymous pipe" technology, but many user applications do not support the "anonymous pipe" technology, and the "anonymous pipe" technology does not support cross-machine calls
