2 Configure Server
2.1 APT Mirror
- vi /etc/apt/mirror.list
set base_path /srv/apt-mirror set nthreads 20 set _tilde 0 set defaultarch i386 deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ precise-backports main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise main/debian-installer restricted/debian-installer universe/debian-installer multiverse/debian-installer clean http://archive.ubuntu.com/ubuntu
- create initial apt-mirror dirs
mkdir -p /srv/apt-mirror/skel /srv/apt-mirror/mirror /srv/apt-mirror/var
- create soft link for pxe clients, clients will use this as install source
ln -s /srv/apt-mirror/mirror/archive.ubuntu.com/ubuntu /var/www/ubuntu
- this is a post mirroring script called by default variable from apt-mirror config
- vi /srv/apt-mirror/var/postmirror.sh
#!/bin/bash DATE=$(date '+%Y%m%d%H%M') cd /srv/apt-mirror/mirror/ echo Starting clean.sh ... /bin/bash /srv/apt-mirror/var/clean.sh test -d backup || mkdir backup ls -1d * | egrep -v '^backup$' | while read MIRROR do cp -al $MIRROR backup/$MIRROR.$DATE done
chmod 755 /srv/apt-mirror/var/postmirror.sh
- if you want apt-mirror to run daily, you can use this config, otherwise call it manually
- vi /etc/cron.d/apt-mirror
apt-mirror
2.2 Kickstart
- this is needed to pull the kickstart files during client setup
mkdir -p /srv/inst/ks rm -f /var/www/index.html ln -s /srv/inst /var/www/inst
- this is just an example, not all vars from RedHat Kickstart are working, google for "Ubuntu Kickstart 12.04"
- vi /srv/inst/ks/u1204-i386-workstation.ks

2.4 DHCPd
On dhcp server, you need to declare the pxe location and its boot file (next-server, filename):
subnet 192.168.123.0 netmask 255.255.255.0 {
range 192.168.123.30 192.168.123.40;
option domain-name "gallien.bitbull.ch";
option domain-name-servers 192.168.123.50, 195.186.1.110;
option broadcast-address 192.168.123.255;
option subnet-mask 255.255.255.0;
option routers 192.168.123.254;
default-lease-time 86400;
max-lease-time 86400;
next-server 192.168.123.64;
filename "pxelinux.0";
# --- KVM VMs on master --------------------------------------------------------
host name { # DNS + DHCP
hardware ethernet 52:54:00:5e:c1:15;
fixed-address 192.168.123.50;
}
