Create new VM on Machine/justice or Machine/freedom
This procedure creates a clone of the Ubuntu Xenial template virtual machine.
virt-clone -o template-xenial --file=/var/lib/libvirt/images/boot/FOOBAR-boot.img --file=/dev/justice/FOOBAR-root -n FOOBAR virsh autostart FOOBAR virsh start --console FOOBAR
- Add A and AAAA records for the new host in the sugarlabs.org zone file (See Service/Nameservers).
- Now login as root from the console (there should be no password)
- setup both IPv4 and IPv6 addresses
vi /etc/network/interfaces
- change machine fqdn
sed -i -e s/template-xenial/FOOBAR/g /etc/hosts /etc/hostname /etc/mailname /etc/postfix/main.cf
- activate new IP and hostname
/etc/init.d/networking restart
- install latest security/stability updates
apt-get update apt-get dist-upgrade
- Find a nice color combo for HOST_COLOR in /etc/zzz_profile.conf
- generate host keys and a key for root
rm /etc/ssh/ssh_host_* dpkg-reconfigure openssh-server ssh-keygen -N "" -f /root/.ssh/id_rsa -t rsa
- Setup wizbackup on a backup server (See Service/backup)
- Move daily, weekly, monthly cronjobs to a unique timeslot to avoid cpu/net storms
vi /etc/crontab
- The most important thing: come up with a funny quip for this machine
vi /etc/motd.tail
- Taa--daah!
reboot
- Add the machine to
/etc/munin/munin.conf
on Machine/sunjammer for monitoring.
[FOOBAR.sugarlabs.org] address FOOBAR.sugarlabs.org
