debootstrap

Gebruik debootstrap om een maagdelijke machine te bouwen.

root@dom0:~# debootstrap --arch amd64 \
 --include=ssh,mc,locales-all,localepurge,subversion,cfengine3,nfs-common,less \ 
 squeeze /var/lib/vz/private/100 http://mirror.webhuis.nl:3142/debian

Met behulp van de include optie is een nuttig aantal packages toegevoegd. openVZ maakt bij de eerste start van een machine het bestand /etc/vz/conf/100.conf aan:

root@dom0:~# vzctl start 100

Zet de machine voor de volgende stappen daarna weer uit: <per> root@dom0:~# vzctl stop 100 root@dom0:~# vzctl set 100 --applyconfig webhuis-basis --save root@dom0:~# sh -c 'echo "OSTEMPLATE=debian-6.0" >> /etc/vz/conf/100.conf' root@dom0:~# vzctl set 100 --ipadd 10.99.99.189 --save root@dom0:~# vzctl set 100 --nameserver 10.99.99.187 --save
