Abstract
The invention relates to the index technology, and aiming at the disadvantage that the operation process of the synchronization scheme of the existing index file based on FTP transferring mode, the invention provides an index file synchronized method, an index server and a search system; the index file synchronized method comprises the following steps: the index server leads the index file to be copied to a local virtual directory which is attached to an index file storage directory by SSHFS progress, so as to transfer the index file to the index file storage directory of the search server by SSHFS progress. The invention further provides the index server and the search system; the local virtual directory is attached to the index file storage directory on the search server by transferring the SSHFS progress, and the index server leads the index file to be copied to the local virtual directory, and the SSHFS progress is used to transfer the index file to the search server, the operation process is simple and easy and the transferring efficiency is high.
Description
Technical field
The present invention relates to index technology, more particularly, relate to a kind of index file method for synchronous, index server and search system.
Background technology
Along with the maturation day by day of digital information memory technology, the full-text search of information has obtained using widely.From internet search engine, to the library book search, the application of information global search technology is seen everywhere.
In the face of huge information bank,, often need the information architecture index for improving the efficient of full-text search.With the internet search engine is example, and search engine companies must be to a large amount of web data index buildings that excavate every day, could ensure that every day, number was responded fast in necessarily Webpage search request.Index construct task computation amount is big, needs the special hardware device of configuration to finish.Therefore, in the prior art, often dispose special index server and come execution index to make up task.In this case, concrete search mission (be about to the key word of input and the index of structure and mate, with the output Search Results) will be finished by special search server.
Because index file often upgrades, therefore need be between index server and search server index file synchronously.Prior art adopts the FTP load mode to come synchronous index file usually.Although can finish the transmission task of index file, there are many defectives in the FTP load mode.For example, at first, the FTP load mode need be carried out comparatively complicated FTP configuration.Secondly, in concrete use, the FTP load mode need be carried out the application layer operation of series of interactive.Once more, the FTP load mode all needs to carry out password authentification before each transport process begins, and can begin to transmit being proved to be successful the rear, if the FTP authentication password for example changes through revising, then transmit leg can't re-use original password and carries out file and transmit.This shows that the operating process of FTP load mode is very complicated.
Therefore, need a kind of index file synchronization scenario, can effectively overcome the above-mentioned defective that exists among the prior art.
Summary of the invention
