Local boot mapping file-based diskless computer boot method

Abstract

The invention discloses a local boot mapping file-based diskless computer boot method, which comprises the following implementation steps of: (1) establishing a DHCP (Dynamic Host Configuration Protocol) server and a boot server; (2) booting a kernel and a temporary root file system by a client machine through a locally stored boot mapping file, acquiring network configuration information and a boot server address of the machine to the DHCP server, configuring a host network and transmitting an MAC (Media Access Control) address request boot file to the boot server; (3) storing, by the boot server, a registered MAC address of the client machine and transmitting a boot file path to the client machine, and periodically controlling access authority of the client machine to the boot file path according to the current MAC address of the client machine; and (4) receiving, by the client machine, the boot file path transmitted by the boot server and mounting the boot file path, and switching to a formal root file system and booting an operating system. The local boot mapping file-based diskless computer boot method has the advantages of high boot efficiency, high boot speed, good universality and high safety and reliability.

Description

technical field [0001] The invention relates to the field of diskless computer systems, in particular to a diskless computer startup method based on a local startup image file. Background technique [0002] At present, with the continuous improvement of computer switching technology, the use of local area networks is becoming more and more extensive, but there are more and more problems that follow. The following two points are one of the main problems: [0003] 1. With the continuous improvement of computer storage technology, the capacity of storage media continues to increase, the free space on the disk is increasing, and the space utilization rate is getting lower and lower. Especially for large and medium-sized LAN users (such as company work computers or Internet cafes, etc.), their data repetition rate is high, and there are a large number of identical operating systems, application software, video and games on the hard disk. These duplicate data and idle disks lead...

AI Technical Summary

Problems solved by technology

These duplicate data and idle disks lead to serious waste of hard disk resources

[0004] 2. It is quite cumbersome to maintain each terminal in the LAN

In addition, the codes stored in the built-in BootROM chips of mainstream commercial network cards in the market are all compiled and generated by X86 instructions, which cannot be used on computers with non-X86 architectures, which limits the types of client terminal computers

[0026] 2. Simultaneous startup of multiple clients will cause network congestion

However, at this time, the system can do nothing except wait for the download of the boot image to complete, resulting in low boot efficiency and long waiting time
