1. A method for implementing package pre-fetching for remote program installation, the method comprising: receiving a package request for a package required for an installation of an operating system and at least one peripheral application thereof from a computing node; determining a package request sequence by which the computing node issues at least one package request according to a type of the computing node, so as to pre-read a subsequent package into a cache before the computing node issues a request for the subsequent package; storing identification information of each computing node in the computing node type database in an association with a computing node type; and searching for a corresponding computing node type in the computing node type database in order to determine the package request sequence.
