Laravel 8 has many options to use different types of databases. For example, we can use SQLite, MYSQL, PostgreSQL, SQL Server, Laravel-OCI8 for Oracle Database. Sometimes, to Speed Up Our Application or Simplify Our Large-Database Application we needs to use Multiple Database for our Single Laravel Application. So, Here in this tutorial we will learn Laravel 8 Multiple Database and Resource Routes with Controllers.
To use the Multiple Database in Laravel, we needs to create Database Configuration, set ENV Variables, create Migrations, Eloquent Model, Controller and Routes. Just follow the Steps given below.
**Note: **If you have not installed the Laravel 8 then read this tutorial Install Laravel 8.
Step 1 – Create Configuration For Database in Laravel 8
Here we will create the config for MYSQL Database. You need to open the database.php file in config directory. Inside the connections array there is a mysql key by default for first database. You just need to create one more key mysql2 for second database and paste the code given below.
'mysql2' => [
'driver' => 'mysql',
'url' => env('DATABASE_URL'),
'host' => env('DB_HOST2', '127.0.0.1'),
'port' => env('DB_PORT2', '3306'),
'database' => env('DB_DATABASE2', 'forge'),
'username' => env('DB_USERNAME2', 'forge'),
'password' => env('DB_PASSWORD2', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'prefix_indexes' => true,
'strict' => true,
'engine' => null,
'options' => extension_loaded('pdo_mysql') ? array_filter([
PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
]) : [],
],
Step 2 – Set Environment Variables in Laravel 8
Open .env file and set the database credentials as given below in code. Remember, DB_HOST2, DB_PORT2, DB_DATABASE2, DB_USERNAME2, DB_PASSWORD2 is for second database.
#First Database
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laraveldb1
DB_USERNAME=root
DB_PASSWORD=
#Second Database
DB_HOST2=127.0.0.1
DB_PORT2=3306
DB_DATABASE2=laraveldb2
DB_USERNAME2=root
DB_PASSWORD2=
Step 3 – Create Eloquent Model in Laravel 8
Before creating the models we will create two sample database tables.
In Database(laraveldb1) Create a table(Customers) with fields – id, customer_name, customer_email, created_at, updated_at, deleted_at.
In Database(laraveldb2) Create a table(Staff) with fields – id, staff_name, staff_email, created_at, updated_at, deleted_at.
Inside app\Models directory create a File Customer.php and paste the code given below.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Customer extends Model
{
use HasFactory;
protected $table = 'customers';
protected $connection = 'mysql';
}
Again inside app\Models directory create a File Staff.php and paste the code given below.
<?php
namespace App\Models;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
class Staff extends Model
{
use HasFactory;
protected $table = 'staff';
protected $connection = 'mysql2';
}
In both the models Customer and Staff we have used the model properties $table to define table name and $connection to define the connection we have created in Step 1.
Step 4 – Create Controllers in Laravel 8
First, inside the app\Http\Controllers directory create a file CustomerController.php and paste the code given below.
<?php
namespace App\Http\Controllers;
use App\Models\Customer;
use Illuminate\Http\Request;
class CustomerController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
//
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
$customer = new Customer;
$customer->customer_name = 'Customer 1';
$customer->customer_email = 'customer1@example.com';
if ($customer->save()) {
return response()->json(['message' => 'Customer Added.']);
}
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
//
}
/**
* Display the specified resource.
*
* @param \App\Models\Customer $customer
* @return \Illuminate\Http\Response
*/
public function show(Customer $customer)
{
//
}
/**
* Show the form for editing the specified resource.
*
* @param \App\Models\Customer $customer
* @return \Illuminate\Http\Response
*/
public function edit(Customer $customer)
{
//
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param \App\Models\Customer $customer
* @return \Illuminate\Http\Response
*/
public function update(Request $request, Customer $customer)
{
//
}
/**
* Remove the specified resource from storage.
*
* @param \App\Models\Customer $customer
* @return \Illuminate\Http\Response
*/
public function destroy(Customer $customer)
{
//
}
}
In create method we have used the Customer Model to insert data in customers table. You can read about database queries using Eloquent Model.
Now, inside the app\Http\Controllers directory create a file StaffController.php and paste the code given below.
<?php
namespace App\Http\Controllers;
use App\Models\Staff;
use Illuminate\Http\Request;
class StaffController extends Controller
{
/**
* Display a listing of the resource.
*
* @return \Illuminate\Http\Response
*/
public function index()
{
//
}
/**
* Show the form for creating a new resource.
*
* @return \Illuminate\Http\Response
*/
public function create()
{
$staff = new Staff;
$staff->staff_name = 'Staff 1';
$staff->staff_email = 'staff1@example.com';
if ($staff->save()) {
return response()->json(['message' => 'Staff Added']);
}
}
/**
* Store a newly created resource in storage.
*
* @param \Illuminate\Http\Request $request
* @return \Illuminate\Http\Response
*/
public function store(Request $request)
{
//
}
/**
* Display the specified resource.
*
* @param \App\Models\Staff $staff
* @return \Illuminate\Http\Response
*/
public function show(Staff $staff)
{
//
}
/**
* Show the form for editing the specified resource.
*
* @param \App\Models\Staff $staff
* @return \Illuminate\Http\Response
*/
public function edit(Staff $staff)
{
//
}
/**
* Update the specified resource in storage.
*
* @param \Illuminate\Http\Request $request
* @param \App\Models\Staff $staff
* @return \Illuminate\Http\Response
*/
public function update(Request $request, Staff $staff)
{
//
}
/**
* Remove the specified resource from storage.
*
* @param \App\Models\Staff $staff
* @return \Illuminate\Http\Response
*/
public function destroy(Staff $staff)
{
//
}
}
Same, In create method we have used the Staff Model to insert data in staff table. You can also read about database queries using Eloquent Model.
Step 5 – Create Resource Route in Laravel 8
Inside the routes directory open web.php file and paste the code given below.
use App\Http\Controllers\CustomerController;
use App\Http\Controllers\StaffController;
Route::resource('customers', CustomerController::class);
Route::resource('staffs', StaffController::class);

This tutorial provides a step-by-step guide on implementing multiple databases in Laravel 8. It covers creating a configuration for the second database, setting environment variables, creating Eloquent models for each database connection, creating controllers for the resources, and defining resource routes. By following this tutorial, anyone can be able to optimize their Laravel application and manage large databases more efficiently.
Also, it will be great if you could provide some recommendations for managed laravel hosting.
