Sysadmin/Add virtual machine

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.
