You can use an answer file...

THere are 2 ways to do this.

THe easy way is to go through an installation, and record your keystrokes in the config step...

So, for a standard install, all defaults, with an admin password of "test123" I do this:

./install.sh
return
return
etc... then in the config
return
5
6
test123

a
n
y

So if you create a text file with [return], 5[return], etc in it, you can redirect that file into install.sh:
./install.sh < textfile
