Copy install files of redhat

mkdir /misc/redhat 

insert each install CD of RedHat

mount /dev/cdrom /mnt/cdrom 

if CD1

cp -var /mnt/cdrom/. /misc/redhat 

other CDs

cp -var /mnt/cdrom/RedHat /misc/redhat umount /mnt/cdrom eject 

Setup NFS server

Related files

/etc/exports -- config file
/usr/sbin/exportfs
/usr/sbin/showmount -- check
/var/lib/nfs/xtab -- log

Setting

echo "/mis/redhat 192.168.2.0/24(ro,no_root_squash)" >> /etc/exports 

ro -- readonly
no_root_squash -- every user on remote is nobody except root

Start

service portmap start
service nfs start

Usage

mount –t nfs -o soft,intr,timeout=30 192.168.2.119:/usr/home /usr/home/ 

• timeo=n

This sets the time (in tenths of a second) the NFS client will wait for a request to complete. The default value is 7 (0.7 seconds). What happens after a timeout depends on whether you use the hard or soft option.

• soft

Soft-mount (as opposed to hard-mount) the driver. This option causes an I/O error to be reported to the process attempting a file operation when a major timeout occurs.

• intr

Allow signals to interrupt an NFS call. Useful for aborting when the server doesn't respond.

copy to NFS directory

cp ks.cfg /misc/redhat 

enter the following command at the boot: prompt:

linux ks=nfs:192.168.2.119:/misc/redhat/ks.cfg 

Note

When installing, it has following message:

Could not allocate requested partitions Partitioning failed:
Could not allocate partitions Press OK to reboot your system  

Maybe partitions are too large.

DHCP

Append this to /etc/dhcp.conf

allow booting;
allow bootp;
class "pxeclients" {
match if substring(option vendor-class-identifier, 0, 9) = "PXEClient";
 next-server <server-ip>;   
filename "linux-install/pxelinux.0";
} 

Then

service dhcpd restart 

server-ip is tftp server's ip, e.g. 192.168.2.119

PXE

Set bios for DELL

Selecting MBA UNDI allows the system to boot from the network server. The MBA UNDI option appears under Boot Sequence only if the Network Interface Controller option is set to On w/MBA. If the Network Interface Controller option is set to On or Off, set it to On w/MBA and then press <Alt><b> to save the change and reboot the system. MBA UNDI then appears under Boot Sequence.

set tftp server

/sbin/chkconfig --level 345 tftp on 
mkdir /tftpboot/linux-install
cd /tftpboot/linux-install
cp /usr/lib/syslinux/pxelinux.0 ./

mkdir pxelinux.cfg
cp /mnt/cdrom/isolinux/isolinux.cfg ./pxelinux.cfg/default
cp /mnt/cdrom/isolinux/*.msg ./ 

set boot item

Add this into boot.msg

-  To auto install Red Hat Enterprise Linux, type:     autoinstall <ENTER>. 

Add this into default.

label autoinstall   kernel vmlinuz   append ks=nfs:192.168.2.119:/misc/redhat/ks.cfg initrd=initrd.img 

Then at the "boot:" prompt type "autointall".
