How to set up a server automatically?

Question

ubuntu

the essence is this. there are 8 vps servers on ubuntu 12.04 32bit
you need for all 8, one at a time or all at once, register such
ssh -X [email protected] (if for all at once, then how?)
apt-get update
apt-get install xfce4
if that -something asks - then Enter
apt-get install vnc4server
vncserver :1 -geometry 1024x768 -depth 16 -pixelformat rgb565
will ask for a password - you need to enter
apt-get install firefox
apt-get install gnome-schedule
vncserver -kill :1
reboot
how to do that is it not to enter for each separately (but for everything at once)
or for one but autocomplete?
