How to create and include a local settings file to define and override environment-specific variables, and keep sensitive things like your database credentials and API keys safe.

|
|
At the bottom of settings.php, add the following code:
|
|
|
|
~~~php
|
|
$local_settings = __DIR__ . '/settings.local.php';
|
|
if (file_exists($local_settings)) {
|
|
include $local_settings;
|
|
}
|
|
~~~
|
|
|
|
This allows for you to create a new file called settings.local.php within a sites/* directory (the same place as settings.php), and this will be included as an extension of settings.php. You can see the same technique being used within Drupal 8's [default.settings.php](http://cgit.drupalcode.org/drupal/tree/sites/default/default.settings.php#n621) file.
|
|
|
|
Environment specific settings like `$databases` and `$base_url` can be placed within the local settings file. Other settings like `$conf['locale_custom_strings_en']` (string overrides) and `$conf['allow_authorize_operations']` that would apply to all environments can still be placed in settings.php.
|
|
|
|
settings.php though is ignored by default by Git by a .gitignore file, so it won't show up as a file available to be committed. There are two ways to fix this. The first is to use the `--force` option when adding the file which overrides the ignore file:
|
|
|
|
git add --force sites/default/settings.php
|
|
|
|
The other option is to update the .gitignore file itself so that settings.php is no longer ignored. An updated .gitignore file could look like:
|
|
|
|
~~~
|
|
# Ignore configuration files that may contain sensitive information.
|
|
sites/*/settings.local*.php
|
|
|
|
# Ignore paths that contain user-generated content.
|
|
sites/*/files
|
|
sites/*/private
|
|
~~~
|
|
|
|
This will allow for settings.php to be added to Git and committed, but not settings.local.php.
