Open issues

Operating Environment

yum install yum-utils
This package will enable you to download packages, without installing them. So you can populate your kickstart server with packages that didn't come with the Install media.

Network

Administration

Creating the NFS export Structure

  1. mkdir -p /exports/ks/configs
  2. mkdir -p /exports/ks/images
  3. update /etc/exports
/exports/ks/configs             192.168.42.0/255.255.255.0(ro,no_root_squash)
  1. service nfs restart


populate an install directory for kickstart use

  1. mount -o loop /exports/isos/images/rhel6beta2.iso /mnt
  2. pushd /mnt
  3. cp -r * /exports/ks/images/rhel6beta2
  4. update /etc/exports
/exports/ks/images/rhel6beta2  192.168.42.0/255.255.255.0(ro,no_root_squash)


Kickstart config file

To create the config file use:

Fedora
/usr/bin/system-config-kickstart
    • (install by: yum install system-config-kickstart)



# Kickstart file automatically generated by anaconda.

# Tells the system to install a fresh system rather than upgrade an existing system.
install

# Install from the NFS server specified.
nfs --server=192.168.42.132 --dir=/exports/ks/images/rhel6beta2

# If present, X is not configured on the installed system.
skipx

# Perform the kickstart installation in text mode.

Adding a package to the repository

  • yumdownloader sysstat: Downloads the 'sysstat' packages, to the current directory, and with the same architecture as the current system architechture.
    • 'uname -m' will print the system architecture.


setting up a boot server

  1. yum install tftp-server dhcp httpd syslinux
  2. vi /etc/dhcp/dhcpd.conf
subnet 192.168.42.0 netmask 255.255.255.0 {
  range 192.168.42.10 192.168.42.24;
  default-lease-time 3600;
  max-lease-time 4800;
  option routers 192.168.42.1;
  option domain-name-servers 192.168.42.1;
  option subnet-mask 255.255.255.0;
}

host booty {
  hardware ethernet 00:54:20:7a:7e:8a;
  fixed-address 192.168.42.21;
  option host-name "booty";
  filename "pxelinux.0";
}
 
  1. vi /etc/xinetd.d/tftp
    • Change ' disable = no'
  2. Insert the Fedora DVD
  3. mount /dev/dvd /mnt
  4. cp vmlinuz initrd.img /var/lib/tftpboot
  5. cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
  6. cd /var/lib/tftpboot
  7. mkdir /var/lib/tftpboot/pxelinux.cfg
  8. touch 01-00-54-20-7A-7E-8A
  9. touch C0A830A0
  10. vi pxelinux.cfg/default
prompt 1
default linux
timeout 100

append initrd=initrd.img ramdisk_size=9216 noapic acpi=off
 
  1. Follow: https://fedoraproject.org/wiki/Kickstart_short_cuts_for_noobs#Creating_the_NFS_export_Structure
  2. Test that the boot works.
  3. Add kickstart as per 'Booting With Your Kickstart Files' in http://www.linuxhomenetworking.com/wiki/index.php/Quick_HOWTO_:_Ch25_:_Network-Based_Linux_Installation
  4. Change the 'append' line in the default file to:
    • append initrd=initrd.img ramdisk_size=9216 noapic acpi=off ks=nfs:192.168.42.1:/exports/ks/configs/fedora14.ks

Local repository

See the reference in the reference list.

  1. yum install lighttpd
  2. vi /etc/lighttpd/lighttpd.conf
    • enable mod_aliases
    • add 'alias.url = ( "/yum" => "/exports/isos/repos" )'
  3. chkconfig lighttpd on
  4. /etc/init.d/lighttpd start

Trouble shooting

kickstart

I have to select the NIC to use for the installation

During the boot, on a multi NIC system, I'm asked to choose which NIC to use for the installation.

use the ksdevice=eth3 in the kickstart command.

on virt-install put it inside the -x"PARMS" parameter.
