Installing ColdFusion 8 on Ubuntu was not complex actually it was very straight-forward.

Here are the three helpful links I used.

1. Installing LAMP On Ubuntu For Newbies
2. Installing ColdFusion 8 on Ubuntu Feisty Fawn
3. ColdFusion 8 Install On Ubuntu

I stopped on Step 28 on the second link and ran the 2 commands listed before exiting the ColdFusion installation process. The commands were "cd /opt/coldfusion8/bin" and "sudo ./coldfusion start". Also my Apache settings didn't match the settings in the second link so I used the settings in the third link.
