Sysadmin/Add virtual machine

Create new VM on Machine/treehouse

This procedure creates a clone of the Sysadmin/Template virtual machine.

virsh vol-create-as treehouse FOOBAR-root 10G
virt-clone --prompt -o template-lucid --file=/dev/treehouse/FOOBAR-root -n FOOBAR
virsh start --console FOOBAR

Add A and AAAA records for the new host in the sugarlabs.org zone file (See Sysadmin/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-lucid/FOOBAR/ /etc/hostname /etc/postfix/main.cf

activate new IP and hostname

/etc/init.d/networking restart

install latest security/stability updates

aptitude update
aptitude full-upgrade

generate host keys and a key for root

ssh-keygen -N "" -f /etc/ssh/ssh_host_rsa_key -t rsa
ssh-keygen -N "" -f /etc/ssh/ssh_host_dsa_key -t dsa
ssh-keygen -N "" -f /root/.ssh/id_rsa -t rsa

Install /root/.ssh/id_rsa.pub key on sugarbackup@backup.sugarlabs.org

Setup backups

vi /etc/system-full-backup.conf

Log in for the first time on backup server to accept ssh fingerprint

ssh sugarbackup@backup.sugarlabs.org

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.
