Stacki can use CSV-formatted spreadsheets to automate server configuration. These few slides give you a preview on how to do it. Stay tuned for the comprehensive tutorial coming soon. www.stacki.com

1. Automate Server Configuration Using
Spreadsheets
Don MacVittie, Sr. Solutions Architect

2. Overview
• Stacki can use CSV-formatted
spreadsheets to automate server
configuration.
• Stacki installs everything necessary to
make a fully functional Linux server.
• Utilizing just two command lines,
spreadsheet configuration can install one
or many servers without human interaction.
• This means that an entire server farm can
be automatically installed (in parallel) while
you’re on a break.

3. Spreadsheet Configuration
The Spreadsheet format:
Name – server host name.
Appliance – the type of machine to install.
IP – the IP address to assign the primary NIC.
MAC – the MAC address to associate the IP with.
Rack – the rack this server resides in.
Rank – the location in the rack.
Subnet – the Stacki subnet the NIC we just defined should be defined on.

4. Tell Stacki About It
• Copy the spreadsheet out to the Stacki server.
• Issue the commands (in red) below to load the spreadsheet and validate that
Stacki now knows about your servers.
• Note in stack list host that the Stacki server (donrh7 in this sample) is in the host
list.
[root@donrh7 ~]# stack load hostfile file=stacki.cocoamaster.csv
/export/stack/spreadsheets/RCS/stacki.cocoamaster.csv,v <-- /export/stack/spreadsheets/stacki.cocoamaster.csv
initial revision: 1.1
done
/export/stack/spreadsheets/RCS/stacki.cocoamaster.csv,v --> /export/stack/spreadsheets/stacki.cocoamaster.csv
revision 1.1 (locked)
Done
[root@donrh7 ~]# stack list host
HOST RACK RANK CPUS APPLIANCE DISTRIBUTION RUNACTION INSTALLACTION
donrh7: 0 0 1 frontend default os install
backend-0-0: 0 0 1 backend default os install
cocoamaster357-storage: 0 1 1 backend default os install
[root@donrh7 ~]#

5. Telling Stacki it’s Time to Install
Just tell Stacki that is time to install
with the commands (in red) below,
and boot the servers. They’ll install,
no need to watch them.
But no matter how many servers
you’re installing, it’s fast, so feel free
to watch if you like.
[root@donrh7 ~]# stack set host boot cocoamaster357 action=install
[root@donrh7 ~]# stack set host attr cocoamaster357 attr=nukedisks value=true
[root@donrh7 ~]#

6. Multiple NICS
Notice our spreadsheet has two lines for
cocoamaster357? That’s because we’re
defining two Network Interface Cards
(NICs) for this server.
The first line defines the host and the
NIC on Stacki’s private network
The second line adds the information to
define a second NIC on the public
network.
That is all you need. Since we loaded
this spreadsheet and installed
Cocoamaster357, it now has two NICs
defined, one on each network.
To the right are the calls to show the
configuration.
[root@donrh7 ~]# ssh cocoamaster357
