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.pubkey onsugarbackup@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.confon Machine/sunjammer for monitoring.
