Sorry for the typos - should be fixed below! If I find any more, I'll update it on the blog post (http://www.deborahwazir.com) Deborah Wazir HP/Delphi Global Server Engineering Email: deborah.wazir@xxxxxx ------------------------------------------------------ HOW TO CREATE CUSTOM BUILD ISO & DVD Log in to server. Be root. Place source DVD in tray. (Source DVD is the RedHat install DVD). Execute "mount" command to figure out path to source DVD. # mount (examine output to see what the path is) (in my case, path is /media/RHEL_5.3 i386 DVD) # cd /media/RHEL_5.3\ i386\ DVD (the backslashes are to escape the spaces in the pathname) # du -sh . (see how much space will be necessary to recreate this DVD on the server hard drive) # df -h (examine output and select a filesystem on the hard drive that has sufficient space to recreate the DVD there) (on my system, I selected /0b) # mkdir /0b/iso_tree (create a working directory on your selected filesystem) # pwd (make sure you are in the top-level of mounted DVD) # tar cvf - . | (cd /0b/iso_tree; tar xvpf -) (recreate the DVD on your hard drive - should take 10 minutes or less) Validation Check: # ls -a /0b/iso_tree (make sure you see a listing for .discinfo file) ------------------------------------------------------------------------ Customize: ----------- # cd /0b/iso_tree/isolinux # mkdir EXTRAS (In my case, I create this subdirectory because I've written some code in my custom ks.cfg file which will copy the contents of the EXTRAS subdirectory into a directory on the server, in the post-installation steps) (We want to put the custom ks.cfg file in the ./isolinux directory, as the deployment guide I'm writing for work expects to find the ks.cfg file there.) (In my case, I have these files on a USB stick which is attached to my server at the mount point /media/disk) # cp /media/disk/ks.cfg /0b/iso_tree/isolinux/ks.cfg # cp /media/disk/tools.tar.gz /0b/iso_tree/isolinux/EXTRAS/tools.tar.gz Here you can make it interesting, because you can actually put multiple versions of ks.cfg here, and can pretty much name them what you want; later when you go to build a new server, you will specify the path to the ks.cfg file anyway. ---------------------------------------------------------------------- Make the custom ISO image file: Decide what the ISO image will be called. In my case, I decided to call it "RedHatLinux53-yyyymmdd.iso", where yyyymmdd represents the year, month, day that I'm creating the file. # cd /0b/iso_tree # mkdir /0b/new_iso (Here you are creating another working directory to put your custom ISO file in - mine needed a little less than 4Gb) Now you execute the "mkisofs" command to create the custom ISO file. This command is all on one line. You might want to put it in a small shell script and execute it that way to avoid typo errors. # mkisofs -A "Red Hat Linux 5.3" -V "Red Hat Linux 5.3" -J -R -v -T -b isolinux/isolinux.bin -c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -o /0b/new_iso/RedHatLinux53-20090901.iso . (PLEASE NOTE THE "." at the end of the command - this stands for "current directory", don't forget to put this at the end of the command!) (Should take around 5 minutes to complete) Validate: --------- Mount the newly created ISO image on the loopback device so you can make sure it will work: # mkdir /0b/mnt_iso (here you are creating a mount point) # mount -o loop /0b/new_iso/RedHatLinux5.3-20090901.iso /0b/mnt_iso (make sure it mounts ok and you can find isolinux/ks.cfg and isolinux/EXTRAS/tools.tar.gz) # umount /0b/mnt_iso ----------------------------------------------------------------------------------------- Now at this point you want to write the ISO image to DVD. Being pressed for time at work, I chose not to investigate the options for using the "cdrecord" command on my Linux server to do that. Instead, I chose to put the ISO file on a USB stick and transfer it over to my PC, then use Roxio to burn a DVD from the ISO image. So here are the instructions for doing that: # cp /0b/new_iso/RedHatLinux5.3-20090901.iso /media/disk (On a slow server, took around a half hour) # eject /media/disk Remove USB stick from server and attach to PC. Use Roxio. Use DVD-R, as DVD+R etc. has sometimes caused a problem. Use option to "Burn Image". Choose the option to "Verify". (Takes about 20 minutes) Test DVD: --------- Place DVD in CD tray in the server you want to build. It should boot from DVD. At the Linux boot: prompt, type the command which will initiate the install, using the custom ks.cfg found at isolinux/ks.cfg. ON my server, the path to the DVD is /dev/sda1, so this is the boot command I use: boot: linux ks=sda1:/isolinux/ks.cfg (NOTE: you don't have to type "boot:" that is the prompt you will see.) If all goes well, the installation will carry on and you won't be prompted for anything. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
