Setting Up Subdomains in Linode and Apache

I’ve been using Linode for a few months to host about a dozen websites and I’ve been very happy with the experience. I have found the documentation at Linode to be clear and concise, especially when it comes to setting up multiple sites using a standard, Ubuntu-based LAMP (Linux, Apache, MySQL, PHP) configuration.

I decided to take one of the sites to the next level and add a subdomain. (An example of a primary domain is davidpodley.com while a subdomain would be the ‘blog’ in blog.davidpodley.com.) Unfortunately, Linode’s library and other documents was less than clear about all of the steps.

My goal here is to explain, step by step, how to add a subdomain to your Linode service. I suppose this could work for any Ubuntu-based LAMP stack, but this may have some Linode-specific information.
