Abstract

本发明提供一种快速安装OS的方法，涉及操作系统领域，本发明能够将一个一个安装rpm包的繁琐步骤省去，取而代之的是提前准备一个已经预安装好的虚拟根分区，通过块拷贝的方式一次性的复制到真实根分区上。提高了安装速度，加快了批量化部署。

The invention provides a method for quickly installing an OS, which relates to the field of operating systems. The invention can omit the cumbersome steps of installing rpm packages one by one, and instead prepare a pre-installed virtual root partition in advance, through block copying One-time copy to the real root partition. Improve the installation speed and speed up batch deployment.

Description

A kind of method of Fast Installation OS
Technical field
The present invention relates to operating system field, a kind of method particularly relating to Fast Installation OS.
Background technology
Along with the development of technology, installing (SuSE) Linux OS again complicated as before, foolproof installation method allows people transfer to Linux camp from Windows camp easily, and LiveOS first experiences, to people is a kind of, the mode installed afterwards especially. Utilize the above technology that non-technical personnel can be allowed quickly to learn how OS is installed, but for professional, it is sometimes desirable to installation rate, or rapid batchization faster is disposed.
Summary of the invention
In order to solve this problem, the present invention proposes a kind of method of Fast Installation OS.
Generally, house the rpm bag (for redhat mirror image) needed for all installations and a list inside ISO image file, this part of list has the dependence of these rpm bags and the affiliated packet situation of rpm bag. When (Basic is a kind of packet situation) is such as installed when user selects Basic, also it is equivalent to have selected all rpm bags belonging to Basic, and the dependence of these rpm bags, then fdisk is given, by these rpm bags according to the order relied on, one by one be installed to root partition, each rpm bag is installed and is essentially all first decompression rpm file, then scattered file in bag is put under corresponding catalogue, this process is a step the slowest in system installation process, and the present invention mainly solves this crux.
The technical scheme is that
A kind of method of Fast Installation OS, including 1) making of fake root subregion, (2) new mirror image installation; Prepare a fake root subregion that pre-installation is good in advance, copy on true root partition by the mode of block copy is disposable.
The flow process of the making of fake root subregion, is all pre-installed into rpm bag to be mounted in a temporary file system, and the remaining space of this temporary file system can delete, to reach to simplify the purpose of final mirror image.
When using new mirror image that OS is installed, treat that fdisk is complete, it is possible to according to the mode of block copy, above-mentioned temporary file system is copied directly to target hard disk subregion (the dd order in corresponding linux).
The tedious steps installing rpm bag one by one can be saved, the substitute is one fake root subregion that pre-installation is good of preparation in advance, copy on true root partition by the mode of block copy is disposable.
The invention has the beneficial effects as follows.
Simplify the tedious steps installing rpm bag in OS installation process one by one.
Copied to disposable for fake root subregion on the true root partition of purpose by the mode of block copy.
Accompanying drawing explanation
Fig. 1 is old image scheme of installation;
Fig. 2 is that new mirror image makes schematic diagram;
Fig. 3 is new mirror image scheme of installation.
Detailed description of the invention
Below present disclosure is carried out more detailed elaboration:
(1) new mirror image production method:
Old image is mounted on a virtual machine, is similar to old image and the step of OS is installed, OS is installed on the root partition of virtual disk (this virtual disk is exactly a big file relative to physical machine).
Being extracted by the root partition of disk, name rootfs.img, generally this file is very big, by mksquashfs order by rootfs.img boil down to Squashfs file, names squashfs.img.
(2) new mirror image installation procedure:
In ISO file, start to start the script generally init by name installing OS, skip the step installing rpm bag one by one, the substitute is the virtual disk root that carry has been made, order as follows:
mount�Coloopsquashfs.img/squashfs
Rootfs.img under/squashfs catalogue be exactly before the root partition of OS mirror image crossed of pre-installation, by the mode (dd order under corresponding linux) of block copy, rootfs.img is copied in the root partition of true disk of target, then need to adjust the capacity of root partition further according to user.

Claims (3)
