Problems solved by technology

[0003] (1) The use of PXE installation requires the establishment of a PXE server and PXE network, especially the use of 10 Gigabit Ethernet ports for PXE installation, which requires the purchase of 10 Gigabit fiber optic switches, which is expensive
And sometimes there are not many machines that need to install the operating system, but the PXE network does not have the characteristics of fast, small, convenient, etc.
[0004] (2) Use the CD-ROM to guide the system CD-ROM installation, you need to use the CD-ROM and CD-ROM, manually configure the RAID, and manually install the whole process, which is time-consuming and labor-intensive
[0005] (3) Use the method of writing the hard disk image to burn the system image file to the U disk for installation, avoiding the use of CD-ROM and CD-ROM, but still use the installation mode set by the system manufacturer for manual installation, which takes a long time and requires manual configuration.

Embodiment Construction

[0018] The content of the present invention is described in more detail below:

[0019] a) Build a LinuxUSB boot disk.

[0020] 1). Install a Linux operating system on the machine, choose minimal installation, and install all required software, including server network card, RIAD card driver and plug-in NTFS-3G that supports NTFS disk format. After the installation is complete, use tar to package the following folders under / as the machine file system:

[0021] tar –jcvfrootfs.tar.bz2bindevetchomeliblib64mediamiscmntnetoptrootsbinselinuxsrvtmpusrvar

[0022] 2). Unzip the initramfsimg under the boot directory.

[0023] cpio-div < . / initramfs-2.6.32-431.el6.x86_64.img

[0024] 3). Modify the startup script to mount and decompress the file system image created after the kernel starts, and add tar,

[0025] Date, xz and other commands, compress and make initramfs, and the kernel is ready to be completed at this time.

[0026] cd . / initramfs

Abstract

The present invention provides a USB flash disk based method for quickly and automatically installing an operating system, and relates to the field of server operating system installation. The method specially comprises: starting a customized Linux system by using a USB flash disk; performing RAID auto-configuration on a machine in the system; partitioning a virtual disk by using a mbr / pbr file ejected by a disk dd of a machine normally installed with the operating system; and decompressing a file system compressed by machine packing to a corresponding partition to achieve the installation of the operating system. The installation method is high in automation level. The entire installation process only requires a few minutes, thereby greatly shortening the installation time. Meanwhile the USB flash disk based method for quickly and automatically installing the operating system is supportive of Windows and Linux installation and is high in extendibility; and other operating systems still can be added when needed.

Description

technical field [0001] The invention relates to the field of installing an operating system on a server, in particular to a method for quickly and automatically installing an operating system based on a U disk. Background technique [0002] In the current server assembly factory, the installation of the operating system is mostly carried out, which is used for testing or pre-installing the operating system before sales. Many factories use the PXE network to install the operating system, but it is necessary to set up a PXE server and arrange the PXE network, especially to use a 10-Gigabit network port for PXE installation, which requires the purchase of a 10-Gigabit fiber optic switch, which costs a lot. In this process, some factories also need to manually configure RAID before connecting to the PXE network. Some factories use the CD-ROM to guide the installation of the system CD, which requires the use of the CD-ROM and the CD-ROM, and manual participation in the whole pro...
