Have you ever set the hostname on your Ubuntu installation only to want to change later? Here is an easy way to accomplish this and only requires changing a single line in a configuration file.

I’ll attempt to make notes where things differ. Step 1 Setting up subdomains requires using a VirtualHost in Apache.
