model. You can write a service provider, to add configuration items to config/database.php

by default, all Eloquent models use the default database connection settings in the application. If you want to specify a different connection for the model, you can use the $connection attribute:

declare multiple links in database.php , and specify the connection name in the model

protected $connection = 'xxx';

you must declare in database.php. Then pass

protected $connection = 'connect';

or

DB::connection('connect')

to link, if the ip,username,pass are all the same, you can share these variables
