It is really easy to ad more databases in Laravel Homested. Simply edit the Homestead.yaml file (in Windows under C:Usersyour-username.homesteadHomestead.yaml)
Under databases add your databases like this:
# content above omitted databases: - homestead - my_new_database - another_database # content below omitted
If you virtual machine is already running navigate to your Homestead folder and run the command vagrant provision to create the new database(s). If it is not running simply run vagrant up.
You should now be able to access your new database with the default credentials.
