A method for remote update of linux operating system

Abstract

The invention discloses a remote updating method for the Linux operating system. The remote updating method includes the steps that A, an Linux startup medium guides at least one target device to start a system updating program and transmits the version identification of an operating system installation package file needing installating or updating to the system updating program; the operating system installation package file comprises at least a root file system file, an Linux inner core mirror image file and an Linux temporary file system file; B, the system updating program downloads an operating system installation package file in a corresponding version and a data abstract file of the operating system installation package file from an FTP server according to the version identification, and detects whether the data abstract file is correct or not, and if yes, the step C continues to be executed; C, startup codes are installed on a target medium of the appointed target device; D, the downloaded operating system installation package file is decompressed to a root directory of the starting medium, and the operating system is restarted. According to the scheme, the remote updating method can reduce complexity and workload of user operation, facilitates large-scale updating and has good reversibility.

Description

technical field [0001] The present application relates to the technical field of computer software and operating systems, in particular to the Linux operating system, and in particular to a method for remotely updating the Linux operating system. Background technique [0002] Since the invention of the Linux operating system, its good customizability and expansibility enable it to meet different needs in various application environments and to spread and develop rapidly. The Linux operating system can be applied not only to large supercomputers, but also to embedded devices, as well as to daily office equipment and mobile computing terminal equipment. The implementation of these applications benefits from the good customizability and scalability of the Linux operating system. [0003] The Linux operating system supports the operation of many business software systems, and is released and sold to end users along with the business software systems. Since the Linux operating ...

Problems solved by technology

However, this solution still has obvious problems that cannot be solved: one is that it does not solve the problem of large-scale upgrades and updates, and the other is that it does not solve the problem of the complexity of upgrades and updates

In addition, the synchronous update and upgrade scheme needs to transmit a large amount of data on the network, resulting in the system upgrade maintenance time not being effectively shortened, on the contrary it will lead to an increase, which greatly reduces the feasibility of this scheme
