Custom Linux Image Batch deployment initial application

Main uses:

Automatically installs the operating system (Swap partition Interactive input), after the system is installed and automatically executes some custom scripts

1, mount the CD-ROM to/mnt, copy the contents to the new directory

Mount/dev/cdrom/mntmkdir/opt/isocp-rt/mnt/opt/iso

2. Modify the Isolinux.cfg file

Vim/opt/iso/isolinux/isolinux.cfgdefault VESAMENU.C32 changed to default Linux timeout 600 to timeout 30 3 seconds label Linux Menu label ^install or upgrade an existing system menu default kernel vmlinuz append initrd=initrd.img changed to: Label Linu X menu label ^install or upgrade an existing system menu default kernel vmlinuz append initrd=initrd.img ks=cdrom:/ks. Cfg

Where the ks.cfg is located under/opt/iso/, cdrom:/'s path is/opt/iso

3. Define KS.CFG File

4. Reset Repodata

Rm-f repodata/*.gz repodata/*.*.bz2 repodata/*.repomd.xml declare-x discinfo= ' head-1. Discinfo ' Createrepo-u media://$ Discinfo-g Repodata/2a7e0c1da38a40e2961c0cec6acca8b8446d974b1fc055216ebde88bb4a19eb9-c6-x86_64-comps.xml.

5. Re-encapsulation of ISO

Cd/opt/isomkisofs-r-l-r-t-no-emul-boot-j-C isolinux/boot.cat-b isolinux/isolinux.bin-o/root/test.iso-boot-load -size 4-boot-info-table-no-bak.

Re-encapsulate the image to/root/test.iso,test.iso is the created image, the above parameters do not change, unless it is clear what to do

There are several main points to note:

1, when the CD-ROM installation, the temporary directory of CD-ROM is/mnt/source/(when the USB is burned to CD-ROMs, this directory is/mnt/stage2)

2, the installation process system directory for/mnt/sysimage/

If the custom ISO is too large (more than 4G), you will not be able to burn to a normal disc, you can burn to a USB flash drive, make a CD-ROM to use

U disk requires mass production, can refer to http://jingyan.baidu.com/article/20095761bd435ecb0721b4bb.html

The following error occurs when you use a USB flash drive to emulate a CD-ROM (ISO booting in VMware no problem)

Error One:

No driver findunabled to find any devices of the typeneeded for this installation type. Woulud to manually select Yourdevice or use a driver Disk?

Workaround:

After booting from the CD, press the ESC key quickly and enter "Linux all-generic-ide irqpoll pci=nommconf"

Error Two:

Unable to read the group information from repositories. Thisis a problem with the generation of your install tree

Workaround:

Reset the Repodata, and then regenerate the mirror

Rm-f repodata/*.gz repodata/*.*.bz2 repodata/*.repomd.xml declare-x discinfo= ' head-1. Discinfo ' Createrepo-u media://$ Discinfo-g Repodata/2a7e0c1da38a40e2961c0cec6acca8b8446d974b1fc055216ebde88bb4a19eb9-c6-x86_64-comps.xml.
