Unless someone lets me in on an easier process, here are the command line steps to configure a static IP address in Ubuntu Linux (in my case specifically for the BitNami Alfresco appliance):
sudo vi /etc/network/interfaces
For us GUI geeks, pull up a vi refresher if you’re a little rusty. Replace the default line:
iface eth0 inet dhcp
With the following lines (and the proper IP):
iface eth0 inet static
address 192.168.1.10
netmask 255.255.255.0
Save and exit. Reboot.
