oasubuntu.tgz is a tarball containing a fully configured Linux system,
Unbutu server 7.10, with OpenAdmin 2.50c installed and configured 
for a single site installation running under SSL.

See http://richtech.ca/openadmin/docs/admindoc/node4.html for details.
You'll need to look there in any case for system and mysql password
information.

The installation occupies 1,273,856 K which will fit nicely in a 2 gig
partition, with a little room to grow.

To use the the tarball, download it.  Put it on media you can access
from the soon to become OA server.

You need to boot the wannabe server from another partition or from a
bootable Linux CD (Puppy Linux recommended as once you boot from a
Puppy CD you can remove the CD and use it for your installation medium
if desired).

Prepare a 2 gig (recommended minimum) ext3 partition.

To untar the tarball, cd to the new partition root directory and use
the command: tar xpzf /path/to/tarball/oasubuntu.tgz

When you get the shell prompt back edit the /etc/fstab to match your
particular environment.

Edit /etc/network/interfaces to match the static IP you need for your
network (recommended) or comment-out the static IP lines and enable
dhcp (not recommended).  Default is 192.168.1.50

Edit /etc/hosts to be compatible with your network and environment.
Note: Apache 2 will complain about your domain name not matching the
SSL certificate.  The documentation link, above, includes easy
instructions for generating your own self-signed certificate so it
can match the domain/host defined in /etc/hosts.  The script
apache2-ssl-certificate is installed which will let you generate
a quick and easy certificate.

You also need to configure your boot manager.  Grub is installed in
this tarball and if you want to point grub at this partition, edit
/boot/grub/menu.lst to also match your installed environment.  You
may, of course, use lilo if you prefer.

Some installation support might be available.  Write to the maintainer
figueroa at andyfigueroa.us with inquiries.

Good luck, and be careful.
