Create additional databases in Laravel Homestead

I often see Homestead users just using the default homestead database that ships with a new Homestead box, rather than creating a new database specific to their application. When you're hosting multiple applications through your Homestead instance it makes a lot more sense to name your databases per-application, often with a _testing suffix for your test databses. It's actually really easy to add new databases inside your Homestead instance, and here are the instructions for both MySQL and PostgreSQL.

MySQL

// Login to MySQL (password is "secret")
mysql -u homestead -p

// Create the new database
CREATE DATABASE your_app_name;

// Exit MySQL
exit;

PostgreSQL

// Login to PostgreSQL (password is "secret")
psql -U homestead -h localhost

// Create the new database
CREATE DATABASE your_app_name;

// Exit PostgreSQL
