f you re ready to turn the world on its head by unleashing your million-dollar web application to the public, then let this chapter be your starting point. The various web application development platforms in use today have very different deployment methods. If you re using PHP, deployment is usually as simple as dropping the right files into a directory on the remote server (usually via FTP), and then visiting them with your web browser. For PHP applications, there are thousands of hosts, and deployment is simple enough for your parents to accomplish. However, as we all know, with simplicity comes lack of options. And, as anyone who has developed in a language like PHP knows, simplicity can lead to some pretty complicated situations with your development. Luckily, Rails deployment is nothing like PHP deployment. In the opposite camp, Java/Struts people have some deployment schemes that would make a PhD candidate panic and run away in a cloud of network diagrams. Java deployments can be terribly complex, with a lot of little details to worry about and huge amounts of memory required. Fortunately, Rails is much simpler than that. With Rails, the porridge is just right. Rails takes some setup to get the system purring, but thanks to an ingenious deployment tool known as Capistrano, you can ensure that your ongoing use and maintenance of the server are easier than with something like PHP or Java.

How does Capistrano make Rails deployment easier The secret is that Capistrano knows a lot about what a typical Rails deployment looks like, so you don t need to tell it a lot. It makes many assumptions about your application and your deployment setup, but also provides you with a myriad of ways to override and customize those defaults.

Basically, you tell Capistrano (cap) to deploy, and it remotely grabs a new version of your application from your version control repository (usually Subversion), swaps the old code with the new, and then restarts the servers. (In this example, we re using Mongrel servers, which we ll talk about in the next section.) It s that easy to deploy to production. The best part about this is that it s repeatable. Every time that you make a change to an application and want to deploy the changes, you simply issue the cap deploy command. The only difficult part is the server setup. There are nearly an infinite number of ways to configure your Rails stack, and most of the configuration requires a good grasp of *nix (UNIX, Linux, OS X, and so on) system administration. For instance, Capistrano requires that you have Secure Shell (SSH) configured on your deployment box, with associated users and permissions set up for application deployment. Most novice Rails programmers aren t experts in such things, so we re going to punt here and avoid getting into server specifics. Instead, we ll show you the basics of getting started with Capistrano from the client side.
Capistrano Installation
Before you start using Capistrano, you need to install it. Fortunately, Capistrano is incredibly easy to install using the RubyGems package manager.
$ gem install capistrano --include-dependencies

Bulk updating Gem source index for: http://gems.rubyforge.org Successfully installed capistrano-1.4.1
That s all it takes to install a full working version of Capistrano on your client computer (your development box, most likely). Part of the installation is the addition of a new command-line utility called cap. You can read the help information for most command-line utilities by passing in the --help directive. Let s do that now.
