A. Create Local Repository (yum local)

1. mount REDHAT EL6 DVD IN TO /mnt
mount /dev/cdrw /mnt
2. copy rpms from Packages directory into /opt/source/repo
cd /media/"RHEL_6.2 x86_64 Disc 1"/Packages
mkdir -p /opt/source/repo
cp -rpv * /opt/source/repo
3. Install repocreate utility rpm installation
rpm -ivh deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm python-deltarpm-3.5-0.5.20090913git.el6.x86_64.rpm createrepo-0.9.8-4.el6.noarch.rpm
4. cd /opt/source/repo
createrepo `pwd`
2293/3596 - xz-libs-4.999.9-0.3.beta.20091007git.el6.x86_64.rpm

5. vi /etc/yum.conf
"# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d"
[base-local]
name=RHEL6 $releasever - $basearch
failovermethod=priority
baseurl=file:///opt/source/repo
enabled=1
gpgcheck=0

6. check your current local repository
yum repolist

B. Prepare Kickstart-Server

1. Install all the required packages through yum
yum install syslinux xinetd tftp-server dhcp httpd

2. mkdir /var/lib/tftpboot/pxelinux.cfg
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

3. Open the xinetd settings to enable tftp server
vi /etc/xinetd.d/tftp
# at line 14 change the parameter from yes to no.
Disable=no

4. Restart the service to apply the settings made
service xinetd restart

5. set the service to start with each subsequent system reboots
chkconfig xinetd on

6. Open the file and configure the DHCP Server
vi /etc/dhcp/dhcpd.conf

# Here the next.sever parameter is the address of the kickstart server.
# Subnet definition Global Option
# WARNING = accomodate MAC ADDRESS (hardware ethernet) and IPADDR (fixed address)
Allow booting;
Allow bootp;
authoritative;

# Subnet definition
ddns-update-style interim;
subnet 10.128.57.0 netmask 255.255.255.0 {
range dynamic-bootp 10.128.57.107 10.128.57.110;
option broadcast-address 10.128.57.255;
option routers 10.128.57.1;
filename "pxelinux.0";
next-server 10.128.57.100;
}

host grid-compute-7 {
hardware ethernet 00:50:56:99:E0:61;
fixed-address 10.128.57.39;
option subnet-mask 255.255.255.0;
option routers 10.128.57.1;
option host-name "grid-compute-7";
filename "pxelinux.0";
}
host grid-compute-8 {
hardware ethernet 00:50:56:99:E0:62;
fixed-address 10.128.57.49;
option subnet-mask 255.255.255.0;
option routers 10.128.57.1;
option host-name "grid-compute-8";
filename "pxelinux.0";
}
7. Restart the service and make it permanent
service dhcpd restart
chkconfig dhcpd on

8. Make some required directories
mkdir -p /var/www/html/rhel
mkdir -p /var/lib/tftpboot/rhel6

9. Insert your RHEL 6.2 DVD + Mount it to /mnt
df -h
/media/RHEL_6.2 x86_64 Disc 1

10. Check the contents to see if it is properly mounted
cd /media/"RHEL_6.2 x86_64 Disc 1"

11. copy all the contents to the /var/www/html/rhel directory
cp –arv /media/RHEL_6.2 x86_64 Disc 1/* /var/www/html/rhel

12. After the file copy operation eject the DVD
eject cdrom

12. Copy the vmlinuz and initrd.img files to the tftpboot directory
cp /var/www/html/rhel/images/pxeboot/vmlinuz /var/lib/tftpboot/rhel6
cp /var/www/html/rhel/images/pxeboot/initrd.img /var/lib/tftpboot/rhel6

13. Copy the menu file
cp /usr/share/syslinux/menu.c32 /var/lib/tftpboot/

14. Prepare the boot menu.
vi /var/lib/tftpboot/pxelinux.cfg/default

timeout 100
default menu.c32
menu title === Hell-Me-Kickstart ===
label 1
menu label ^ 1) RedHat Enterprise Linux
kernel rhel6/vmlinuz
append initrd=rhel6/initrd.img ks=http://10.128.57.100/ks/ks.cfg

15. Prepare the httpd server
vi /etc/httpd/conf/httpd.conf

Listen 10.128.57.100:80

service httpd restart
(ignore the fully qualified domain name error if it occurs.)
chkconfig httpd on

vi /etc/hosts
10.128.57.100 kick-server

16. Prepare nfs server
vi /etc/exports
/var/www/html/ks *(rw,no_root_squash)
/var/www/html/rhel *(rw,no_root_squash)

service nfs restart
chkconfig nfs on

exportfs

/var/www/html/ks
/var/www/html/rhel

chkconfig iptables off

disable selinux
vi /etc/selinux/config
SELINUX=disable

shutdown -r now

C. Prepare Kickstart Config (ks.cfg)

1. Make the directory and copy the kickstart file to it

2. And make the kickstart file globally read only (chmod 644)

mkdir -p /var/www/html/ks

mkdir -p /var/www/html/ks/logs

3. vi /var/www/html/ks
