Look at small how-to install
cobbler with yum on
RHEL 4.6 from scratch.
Install the most RHEL 4.6 or
CentOS 4.6 with default partitioning and custom installation (unselect all possible packages during installation procedure). Diable firewall and SELinux.
- Enable DVD repository by changing the line in /etc/yum.repos.d/CentOS-Media.repo
enabled=1
Install yum
mount /media/cdrom
Download packages and install them:
mkdir /var/tmp/cobbler-4.6
cd /var/tmp/cobbler-4.6
rpm -i
./python-elementtree-1.2.6-5.el4.centos.x86_64.rpm \
./python-urlgrabber-2.9.8-2.noarch.rpm ./sqlite-3.3.6-2.x86_64.rpm \

./yum-2.4.3-4.el4.centos.noarch.rpm \
./createrepo-0.4.4-2.noarch.rpm
yum clean all
mkdir /var/tmp/rhel4_repo/
ln -s /media/cdrom/RedHat/RPMS/ /var/tmp/rhel4_repo/RPMS

Install necessary software from DVD
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.orig
yum -y install wget mc

Disable firewall (just for sure):
chkconfig --level 2345 iptables off
service iptables stop
Change line in /etc/cobbler/settings to match the IP of the server:
default_password_crypted: "$1$pH3........0B2HB/"
default_name_servers: [192.168.0.129]
manage_dhcp: 1
manage_dns: 1
manage_forward_zones: [my.domain.cz]
manage_reverse_zones: [192.168.0]
next_server: 192.168.0.129
pxe_just_once: 1
server: 192.168.0.129
register_new_installs: 0
xmlrpc_rw_enable: 1
Start cobbler and apache daemon:
/etc/init.d/cobblerd start
/etc/init.d/httpd start
chkconfig httpd on
Change 'disable' to 'no' in /etc/xinetd.d/tftp
disable = yes
Cobbler/DHCPd/bind configuration
Change listening interface for dhcpd in /etc/sysconfig/dhcpd:
DHCPDARGS=eth0;
Modify file /etc/cobbler/dhcp.template according your needs:
subnet 192.168.0.0 netmask 255.255.255.0 {
option routers 10.226.23.1;
option domain-name "my.domain.cz";
option domain-name-servers 192.168.0.129;
option subnet-mask 255.255.255.0;
range dynamic-bootp 192.168.0.200 192.168.0.254;
filename "/pxelinux.0";
default-lease-time 21600;
max-lease-time 43200;
next-server $next_server;
}
Modify /etc/cobbler/named.template like:
options {
...
# listen-on port 53 { 127.0.0.1; };
...
# allow-query { localhost; };
forwarders { 10.226.32.44; };
...
};
cobbler sync
service xinetd restart
chkconfig dhcpd on
chkconfig named on
Now you should run
cobbler check
and see something like that:
$ cobbler check
No setup problems found
Manual review and editing of /var/lib/cobbler/settings is recommended to tailor cobbler to your particular configuration.
Cobbler repository+ installation

Edit /etc/yum.repos.d/RHEL-4.6-Media.repo and change one line like:
baseurl=file:///var/www/cobbler/ks_mirror/RHEL4.6-x86_64-AS/RedHat
Then run:
yum clean all
PXE configuration
Make this the first line of /etc/cobbler/pxe/pxedefault.template,pxeprofile.template,pxesystem.template to enable serial connection:
SERIAL 0 115200
Cobbler WebUI
Set root password for web access:
htdigest /etc/cobbler/users.digest "Cobbler" root
Change line in /etc/cobbler/modules.conf:
module = authn_configfile
service cobblerd restart
service httpd restart
Cobbler host specification
cobbler system add --comment="c3virt01ce01 machine" --name=c3virt01ce01 --hostname=c3virt01ce01 --netboot-enabled=1 --profile=NGP_RHEL4.6-AS-x86_64 --name-servers=192.168.0.129 --static=0 --kickstart=/var/lib/cobbler/kickstarts/legacy.ks

Hope it will be possible to use PXE boot to install machines.
