Re: boot cd-rom network install on system with no display using vnc



Take boot.iso from the images directory in the RHEL DVD and mount it:
mount -o loop boot.iso /mnt

make a directory and copy all files from /mnt to this dir.
mkdir /root/iso
cd /mnt
cp -pr * /root/iso
cd /
umount /mnt

Look in /root/iso/isolinux

Probably want an isolinux.cfg file like this:

default linux
prompt 0
timeout 0

label linux
    kernel vmlinuz
    append initrd=initrd.img ksdevice={DEV} linux  ip=xx.xx.xx.xx netmask=xx.xx.xx.xx dns=xx.xx.xx.xx gateway=xx.xx.xx.xx vnc vncconnect=xx.xx.xx.xx vncpassword=abcdef  method=nfs:xx.xx.xx:/{PATH TO LINUX_DISTRO EXPORTED FROM NFS SERVER} keymap=us lang=en_US.UTF-8

fill in the details. Dont forget to make an NFS server.

To make the iso file use something like:
mkisofs -o "/root/iso/isolinux.iso" -boot-info-table -b isolinux.bin -no-emul-boot -c boot.cat /root/iso/isolinux

Use this file to boot from an RSA adapter or burn a cd.

Hope this helps

You have to make your own boot cd and insert the information I provided into the isolinux.cfg.

Hi,
Start by running a vncviewer in listen mode (I use realvnc: vncviewer --listen from a command line ). Boot the machine to install linux with the cd-rom and you type:

linux  ip=xx.xx.xx.xx netmask=xx.xx.xx.xx dns=xx.xx.xx.xx gateway=xx.xx.xx.xx vnc vncconnect=xx.xx.xx.xx vncpassword=abcdef method=cdrom keymap=us lang=en_US.UTF-8

You need to specify IP, method, keymap and lang information otherwise it will ask you for this before vnc is running.

the ip address is the address you want to give to the machine your installing linux on. Can also be ip=dhcp
vncconnect is the IP address you ran the vncviewer on
vncpassword is the password. Not sure if it should be encrypted or mot
method=cdrom specify your install media

By booting from a cd-rom you unfortunately have to perform a media check. This requires output to a screen and a few key presses and I don't know if this can be disabled. The way I got round this was to use an NFS server, so the boot line is:

linux  ip=xx.xx.xx.xx netmask=xx.xx.xx.xx dns=xx.xx.xx.xx gateway=xx.xx.xx.xx vnc vncconnect=xx.xx.xx.xx vncpassword=abcdef  \    
    method=nfs:xx.xx.xx:/{PATH TO LINUX_DISTRO EXPORTED FROM NFS SERVER} keymap=us lang=en_US.UTF-8

eg,
method=nfs:10.2.34.123:/export/RHEL5.4/i386

/export/RHEL5.4/i386 is the path on the NFS server to the DVD distribution on disk. You have to copy the contents of the DVD to disk.

Heres a useful web page:

Hope this is of some help.
