Configurazione di Buildbot per le Macchine Virtuali - Debian 6 amd64

Creare la VM:

cd /kvm/vms
qemu-img create -f qcow2 vm-debian6-amd64-serial.qcow2 8G
kvm -m 2047 -hda /kvm/vms/vm-debian6-amd64-serial.qcow2 -cdrom /kvm/debian-6a1-amd64-netinst.iso -redir 'tcp:2244::22' -boot d -smp 2 -cpu qemu64 -net nic,model=virtio -net user

Configurazione della console seriale e dell'account

Dalla directory di installazione, impostare la porta seriale e gli account per il login ssh senza password e sudo:

kvm -m 2047 -hda /kvm/vms/vm-debian6-amd64-serial.qcow2 -redir 'tcp:2244::22' -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user

su
apt-get install sudo openssh-server
visudo

# Aggiungere: %sudo ALL=NOPASSWD: ALL
# aggiungere l'account utente al gruppo sudo `addgroup <USER> sudo`.
# Copiare la chiave ssh pubblica.

# Aggiungere in /etc/inittab:
S0:2345:respawn:/sbin/getty -L ttyS0 19200 vt100

Modificare /etc/default/grub:

sudo vi /etc/default/grub
# Aggiungere/modificare queste voci:
    GRUB_CMDLINE_LINUX_DEFAULT="console=tty0 console=ttyS0,115200n8"
    GRUB_TERMINAL="serial"
    GRUB_SERIAL_COMMAND="serial --unit=0 --speed=115200 --word=8 --parity=no --stop=1"

sudo update-grub

Aggiungere l'utente buildbot, con la password disabilitata. Aggiungere come sudo e aggiungere chiave ssh.

sudo adduser --disabled-password buildbot
sudo adduser buildbot sudo
sudo su - buildbot
mkdir .ssh
# Add all necessary keys.
cat >.ssh/authorized_keys
chmod -R go-rwx .ssh

VM per il build dei .deb

qemu-img create -b vm-debian6-amd64-serial.qcow2 -f qcow2 vm-debian6-amd64-build.qcow2
kvm -m 2047 -hda /kvm/vms/vm-debian6-amd64-build.qcow2 -redir 'tcp:2244::22' -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic

sudo apt-get build-dep mysql-server-5.1
sudo apt-get install devscripts hardening-wrapper doxygen texlive-latex-base ghostscript libevent-dev libssl-dev zlib1g-dev libreadline-dev

VM per testare l'installazione

qemu-img create -b vm-debian6-amd64-serial.qcow2 -f qcow2 vm-debian6-amd64-install.qcow2
kvm -m 2047 -hda /kvm/vms/vm-debian6-amd64-install.qcow2 -redir 'tcp:2244::22' -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic

Si veda General Principles per sapere come creare il file 'my.seed'.

# Nessun pacchetto probabilmente!
sudo apt-get install debconf-utils

cat >>/etc/apt/sources.list <<END
deb file:///home/buildbot/buildbot/debs binary/
deb-src file:///home/buildbot/buildbot/debs source/
END

sudo debconf-set-selections /tmp/my.seed

VM per testare l'upgrade

qemu-img create -b vm-debian6-amd64-install.qcow2 -f qcow2 vm-debian6-amd64-upgrade.qcow2
kvm -m 2047 -hda /kvm/vms/vm-debian6-amd64-upgrade.qcow2 -redir 'tcp:2244::22' -boot c -smp 2 -cpu qemu64 -net nic,model=virtio -net user -nographic

sudo apt-get install mysql-server-5.1
