Abstract

The invention provides a quick medium-free upgrading method for a Linux system. According to the upgrading method, the smoothness and the quickness during updating and upgrading of the Linux system are realized by functions of modifying an initialized boot file of a memory, adding an automatic connection remote server, downloading an upgrade data packet, checking the file integrity, decompressing an alternate file, executing the rollback operation and the like; in addition, the updating and the upgrading can also be realized under the condition of not installing mobile media such as a compact disc and a U flash disk and large-scale quick deployment can be realized.

Description

technical field [0001] The invention belongs to the technical field of Linux operating systems, and relates to a fast medium-free Linux system upgrading method. Background technique [0002] With the development of society, the application of computer involves various fields of society, and as an open source, stable and safe operating system, Linux operating system has been widely used in various fields. At the same time, with the development of software technology and the increasingly severe situation of computer information security, the software update of the Linux operating system is more frequent, which requires the continuous updating and upgrading of the Linux operating system to ensure the information security of the system. [0003] When upgrading the version of the Linux operating system with large changes, due to compatibility issues between the old and new versions of some core software and file systems, the system cannot be upgraded simply by updating the softwa...
