[0032] The example of the present invention mainly optimizes the speed of operating system startup by sorting the files required for startup, figure 1 It is a schematicflow chart of the method for starting the Linux operating system according to the first embodiment of the present invention. The steps of this embodiment will be described in detail below with reference to the accompanying drawings.
[0033] Step S110, start the Linux operating system.
[0034] Step S120, judging whether the specified file exists.
[0035] Specifically, it is judged whether the specified file exists, if the judgment result is no existence, then go to step S130, if the judgment result is existence, then go to step S170.
[0036] It should be noted that the specified file can be a database file, in which the file name of the file required when the operating system starts and the corresponding physical address of the file on the disk are stored, and the stored file name has been stored according ...

Abstract
The invention discloses a startup method for a Linux operation system. The startup method is characterized by comprising the following steps: starting up an operation system; judging whether a designated file exists or not; if no, executing the following steps: starting up the operation system by reading various startup files required by the startup from a magnetic disk; tracking the startup process of the operation system to obtain startup information; sorting various startup files required by the startup based on startup information; storing file names of various startup files required by the startup after sorting and physical addresses of the file names on the magnetic disk to the file; and taking the file as the designated file, wherein the startup information comprises the file names of various startup files required by the startup and the physical addresses of the file names on the magnetic disk. According to the startup method disclosed by the invention, due to the use of a magnetic disk pre-reading technology, the files required by startup are sequentially read from the logic, which shortens the addressing time of the magnetic disk caused by random reading of the files and further reduces the waiting time of the operation system in the startup process.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to a Linux operating system and a starting method thereof. Background technique [0002] Due to the advantages of open source, low software licensing fees and abundant application development resources, the Linux system has been widely used, and has more and more users in civil, office and development fields. [0003] The Linux system has the advantages of being safe and reliable, the kernel can be customized, and the source code is open, but the Linux system also has shortcomings, such as poor real-time performance and long startup time. [0004] Aiming at the problem of too long startup time of the Linux system, due to the complex application environment of the Linux system, the service applications installed in each version of the Linux system are mostly different. Therefore, how to optimize the startup speed of the Linux system more effectively has become an important research...
