This is the installation instructions for SCI-CD project.

You'll need the Internet connection to build CD-ROM¶

The build engine is based on the simple-cdd Debian package.

Install build components¶

$ apt-get install simple-cdd sharutils git

Get project sources¶

$ git clone http://github.com/dmi/sci-cd.git

Use Git magic¶

You should create your own branch to place modifications and to save the
ability to receive updates.

$ cd sci-cd
$ git checkout -b local

For additional useful commands read GITMAGIC

Adjust the environment¶

profiles/SCI-i686.conf¶

You may need to change debian_mirror and security_mirror settings if
you are using another mirrors or apt-proxies.

profiles/SCI-i686.downloads¶

You can add more packages here to make more functional distro on the
CD. It is recomended that you should first try the default list and
then rebuild with your extention.

profiles/SCI-i686.files/postinst.conf¶

Optional. The file should be created.
Tunable parameters:

vlan_no - if set, the control network will be placed in this vlan
using 802.1q tagging.

Build ISO image¶

./build.sh SCI-i686

Burn ISO image¶

Image will be built in images/ folder, burn it with your favorite tool
(for ex. - k3b).

Install the system¶

Install the system on two nodes (you may use only one node, but high
availability capabilities will be unavailable).

You must to know following data at this time:

• The number and mask of local network
• The IP addresses of two installed nodes (in the same network)
• The internet router's address (in the same network, if any)
• The cluster's domain name
• The hostnames for new nodes
• The address of the future DNS server, which will be installed on the
  cluster service instance.
• The root's password
• The idea on how to create storage system - to use MD or hardware raid
  or no raid at all - on your own choice.

Partitioning¶

You should preserve following partitions on your nodes:

Name	Size	Purpose
/	10G	Root partition for all node's data
swap	1G	Swap space for Dom0 in calculation of 384Mb RAM
xenvg	the rest	The LVM Volume, named 'xenvg', without any partitions

xenvg will be used as the default place for instance's volumes.
You may create more partition or volume groups at your choice.

DNS server's address¶

The cluster has it's own DNS server, which is also the 'approx' and
'puppet' server. At the SETUP stage, cluster DNS server can be linked
to other DNS servers in the forwarding mode.

The server's address must not be the address of the existing service.

The cluster's domain name must not be the name of the existing domain if
local domain already exists (use subdomain, or completely different name).

Automatic post-installation changes¶

During the installation phase, the postinst.sh script from the distro
made the following system tuning: POST-INSTALL

The cluster is ready to setup¶

The CD installation takes about 15 minutes per node.
