[0027] figure 2 is a schematicflow chart of the method for safely upgrading the Linux operating system according to the first embodiment of the present invention, please refer to figure 2 , detailing each step of the process.
[0028] Step S210, detecting whether there is a removable storage medium.
[0029] Specifically, the Linux operating system detects whether there is a removable storage medium through the driver software of the removable storage device. If the detection result is yes, that is, it is detected that some kind of removable storage medium exists, then go to step S220, otherwise, end the operation.
[0030] It should be noted that since the operating system in this embodiment is upgraded in a safe mode, in order to avoid risks, the offline mode of removable storage media is used to upgrade the operating system to ensure the security of the installed Linux operating system. Computer confidentiality.

Abstract
The invention discloses a Linux operating system and a security update method of the same, the method comprising: a step of detection, detecting if a removable storage medium exists and if yes, entering a step of query; the step of query, querying if a repository content of softwarepackage for updating exists in the removable storage medium and if yes, entering a step of acquisition; the step of acquisition, acquiring the softwarepackage for updating the operating system based on the repository content of softwarepackage; and a step of updating, updating the operating system based on the software package. By determining the security classification of the computer to be updated and updating throug removable storage medium, the method overcomes the technical problem of being incapable of updating the operating system in the case of offline or confidentiality requirement of the computer and achieves the objective of security update of the operating system.
Description
technical field [0001] The invention relates to the upgrading technology of the operating system in the communication field, in particular to a Linux operating system and a safety upgrading method thereof. Background technique [0002] In the process of software development, it is often necessary to upgrade the related operating system. The Linux operating system consists of various package modules in rpm format. Because these packages are in the process of being constantly updated and bugs fixed, they are often updated to add new features. [0003] At present, the upgrade method of the Linux operating system is to connect to a remote server online through the Internet, and then use a local system upgrade tool to download and install these software packages to achieve the purpose of upgrading the system. The specific upgrade method is as follows: figure 1 shown, from figure 1 It can be known that when there is a network connection, the user connects to a server through t...
