Starting…

Download the last version of wordpress, then create a directory called “wordpress” (or anything you want else to call it) and extract the content of the zip to the directory.

WordPress Configuration

Jump to your directory and create the Procfile with this line
[cce]
web: vendor/bin/heroku-php-apache2 /
[/cce]

Add a file for composer, named composer.json
[cce_php]
{
“name” : “WordPress”,
“require” : {
“php” : “>=5.3.3”,
“ext-mbstring” : “*”
}
}
[/cce_php]

Edit the wp-config.php file and replace the first lines with
[cce_php]
$db = parse_url(getenv(‘CLEARDB_DATABASE_URL’));

define(‘DB_NAME’, str_replace(‘/’, ”, $db[‘path’]));
define(‘DB_USER’, $db[‘user’]);
define(‘DB_PASSWORD’, $db[‘pass’]);
define(‘DB_HOST’, $db[‘host’]);

define(‘AUTH_KEY’, ‘{%AUTH_KEY%}’);
define(‘SECURE_AUTH_KEY’, ‘{%SECURE_AUTH_KEY%}’);
define(‘LOGGED_IN_KEY’, ‘{%LOGGED_IN_KEY%}’);
define(‘NONCE_KEY’, ‘{%NONCE_KEY%}’);
define(‘AUTH_SALT’, ‘{%AUTH_SALT%}’);
define(‘SECURE_AUTH_SALT’, ‘{%SECURE_AUTH_SALT%}’);
define(‘LOGGED_IN_SALT’, ‘{%LOGGED_IN_SALT%}’);
define(‘NONCE_SALT’, ‘{%NONCE_SALT%}’);
[/cce_php]

Create an App with heroku toolbelt setting up the app name my-wordpress-app and the region eu
[cce_bash]
$ heroku apps:create –region eu my-wordpress-app
[/cce_bash]

Database

Creating the database, this will create a free cleardb on heroku and add the system variable CLEARDB_DATABASE_URL:
[cce_bash]
$ heroku addons:create cleardb:ignite
