Installation Profiles This chapter will focus on creating installation profiles. Previous chapters covered building modules and features into Drupal. This chapter will cover bundling modules and themes with an installer that configures Drupal for a specific purpose. Here are some important topics that we will cover in this chapter: • Starting a new installation profile • Bundling modules and themes in a distribution • Creating a .profile file to store installation tasks • Enabling modules in the install process • Configuring the default blocks • Running the installer without using the interactive wizard By the end of the chapter you should have the basic knowledge to create your own installation profile and Drupal distribution. Introducing installation profiles Installation profiles are the way to plug into and customize the Drupal installation process. With installation profiles, additional forms and steps can be added to the installer, modules can be enabled, blocks can be set up, default settings can be configured, and the Drupal site can be customized. An installation profile is useful when you repeat the same install tasks regularly. These tasks can be automated, which is perfect for setting up a Drupal distribution or for situations where you build out the same base site repeatedly.
Installation Profiles Drupal distributions Distributions provide out-of-the-box functionality without the need to download and install anything but the distribution itself. Without a distribution, you typically need to download Drupal and additional modules and themes that you need for the site to operate. Then you need to spend time running through a normal Drupal installation process, followed by time spent configuring the site. With a 'distribution', you download it, run it through the installer, and you have a functioning and a configured site. Distributions build on installation profiles by providing everything you need in one place. Setting up a distribution Distributions consist of Drupal core, additional modules and themes, and an installation profile to configure the site. While going through creating an installation profile, we are also going to walk through the steps needed to create a full-fledged distribution. Standard and minimal profiles Drupal comes pre-packaged with the standard and minimal installation profiles. The standard installation profile installs a common set of core modules. This is similar to the installation profile packaged with Drupal 6. The minimal installation profile installs only the required modules along with the block and dblog modules. Creating a profile directory Profiles are located in the /profiles directory, off the base of the Drupal site. To create a new profile, create a directory alongside the standard and minimal profiles provided by core. The name should be the machine-readable name of the install profile you are creating. Throughout this chapter we will build an installation profile with the name store. Modules, themes, and profiles cannot share the same machine-readable name. This name should be a unique namespace for the Drupal installation. [ 344 ]
