You want to run your database migrations.
php artisan migrate command.
$ php artisan migrate
You'll see a list of what migrations ran.
If you just want to see what would happen if you were to migrate, use the
$ php artisan migrate --pretend
This will show you everything that would happen to your data, but doesn't actually make any changes.
You can seed your database too.
--seed option and your database will be seeded after the migrations occur. That is, if you have any seeds set up.
See Seeding Your Database recipe.
