How to use multiple databases in a single Laravel site
This is very important question we faced recently from our clients that “Can we use 2 database in a Laravel application?”
answer is YES.
Laravel provinding very flexible and robust solutions for developer. It provides options from which we can connect multiple databases for a single application.
There some specific settings need to be done to connect multiple databases in Laravel.
So let me give you step by step process. It’s mentioned below:
Add new database details in your project .env file. There are predefined constants to add database details like below:
You just need to copy and paste it to make another database details and rename all constants to provide a new name like below
Now you need to link this second database details to Laravel database configuration in config/database.php file. Below mentioned code available so you just need to copy and paste this to make another settings like below:
//----- This code will be already in config/database.php,
you need to copy and paste to make new one ----------------//
'mysql' => [
'driver' => env('DB_CONNECTION'),
'host' => env('DB_HOST'),
'port' => env('DB_PORT'),
'database' => env('DB_DATABASE'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
//----- This is new setting for second database from .env file ----------------//
'mysql2' => [
'driver' => env('DB_CONNECTION_SECOND'),
'host' => env('DB_HOST_SECOND'),
'port' => env('DB_PORT_SECOND'),
'database' => env('DB_DATABASE_SECOND'),
'username' => env('DB_USERNAME_SECOND'),
'password' => env('DB_PASSWORD_SECOND'),
By following above two steps, we can connect two different database in our project. And if you are not providing database connection into your Laravel query then it will connect to default database (database 1) and if you provide database connection name then it will connect your called database like below:
//---------- This will connect to database1 -----------------//
$users = DB::select(...);
//---------- This will connect to database2 -----------------//
$users = DB::connection('mysql2')->select(...);
So I hope this article can solve your problem
