Centos4.3-based production of linux releases

 

I 've recently seen many people on the internet struggle to make their own releases, so I took my notes and shared them with you.

 

Note: The Path/data/disk is the path of the CD. You can modify it according to your environment.

 

========================================================== ====================

 

Basic Process:

 

Customized RPM package

Modify comps. xml

Recompile comps. rpm

Regenerate hdlist

Create pkglist

Use buildinstall to process the installer

Use mkisofs to create an installation Image

 

------------------------------------------------

The Master System is centos4.3. To get the latest software, first upgrade your system-related software.

Rpm -- import http://mirror.be10.com/centos/4.3/ OS /i386/RPM-GPG-KEY-centos4

Rpm -- import/usr/share/doc/centos-release-4/RPM-GPG-KEY>/dev/null

Yum-y update

 

The following is a required package for creating and installing a cd

Yum install pump-devel gtk2-devel booty bogl-devel bogl-bterm elfutils-devel beecrypt-devel dietlibc

Yum install anaconda-runtime busybox-anaconda

Booty i386 0.44.3-1 base 85 k

Pyparted i386 1.6.8-2 base 22 k

 

 

 

Check RPM package dependency

Cd/data/disk/EServer/RPMS

Mkdir/tmp/testdb

Rpm -- initdb -- dbpath/tmp/testdb

Rpm -- test -- dbpath/tmp/testdb-Uvh *. rpm

 

The procedure is as follows:

1. Set python system environment variables

Export PYTHONPATH =/usr/lib/anaconda

Export PATH = "$ PATH:/usr/lib/anaconda-runtime"

 

2. Update the file tree of the CD

Genhdlist -- productpath = EServer/data/disk

 

 

3. Generate the pkgfile file required for the next step.

Pkgorder -- product EServer/data/disk/EServer>/data/pkgfile

 

4. compile and generate the CD boot file and image installation interface Image

Buildinstall -- pkgorder/data/pkgfile \

-- Version "1.2 "\

-- Product "EServer "\

-- Release "Beta "\

-- Prodpath EServer/data/disk

 

5. Create ISO

 

Mkisofs-r-T-J-V "EServer 1.2"-B isolinux/isolinux. bin \

-C isolinux/boot. cat-no-emul-boot-load-size 4 \

-Boot-info-table-x "lost + found "\

-O/data/EServer. iso/data/disk

 

 

The file isolinux/boot. cat will be generated later by the mkisofs Program

----------------------------------------------------

 

Generate md5 verification value for the CD

Implantisomd5/data/EServer. iso

Inserting md5sum into iso image...

Md5 = b49c693f83c23d7e746dfe0f81a56016

Setting supported flag to 0

 

 

 

To change the graphic interface to a personalized interface, you need to modify stage2.img (CD boot image. If the hard disk is installed, You need to modify other imgfiles ......)

 

Note:

Anaconda resource modification:

 

Mkdir/data/anaconda

Mount-o loop/data/disk/EServer/base/stage2.img/data/anaconda

Cd/data/anaconda

Tar-cvf/data/stage2.tar.

Mkdir/data/stage2

Cd/data/stage2

Tar-xvf/data/stage2.tar

Chmod + w-R ../stage2

# ----------- Modify a resource -----------------#

.....

....

# Repackaging an img Image

Cd/data

Mkcramfs stage2/stage2.img. new

Cp/data/stage2.img. new/data/disk/EServer/base/stage2.img

 

 

 

 

Disk startup screen modification:

 

Yum-y install syslinux

 

The graphic is in a somewhat odd format, called LSS16. As the name indicates, it is limited to 16 colors. To edit the graphic, first convert it to a PPM:

 

Lss16toppm <splash. lss> splash. ppm

 

Next, edit the file using The Gimp. save the resulting file as an indexed gif with no more than 14 colors (plus black and white, for a total of 16 ). then, convert the file to a pnm/ppm:

 

Giftopnm <splash.gif | ppmtolss16> splash. lss

Cp splash. lss/data/disk/isolinux/splash. lss

 

 

Yum install gcc xorg-x11-devel.

Compiled by gif2lss-0.4.tar.gz

 

 

Make sure that the following packages are in the rpm directory of the CD. These packages are required for graphic creation. Without them, buildinstall will report an error.

 

Anaconda

Anaconda-runtime

Anaconda-help

Anaconda-product

Busybox

Busybox-anaconda

Memtest86 +

Fonts-xorg-base

Rpm-qpi # displays rpm package information

Rpm-Uvh # Install the rpm package

Rpm-qpl # column files in the rpm package

The above steps are post-practice notes, so they are generally successful. There are still some details, such as the modification and syntax of comps. xml.
