SQLSTATE[HY000] [2002] A connection attempt failed because the connected party did not properly respond after a period of time,

问题

I try to connect 2 database in my Laravel 5.6 project, but i got error like this

SQLSTATE[HY000] [2002] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. (SQL: select * from mt_merchant)

I tried following code:

.env

1st db connection (this is in my local server)

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=thedaldb
DB_USERNAME=root
DB_PASSWORD=

2nd db connection (this is in live server IP 18.188.209.59)

DB_CONNECTION_SECOND=mysql
DB_HOST_SECOND= 18.188.209.59
DB_PORT_SECOND=3306
DB_DATABASE_SECOND=delivery_test_copied
DB_USERNAME_SECOND=testuser
DB_PASSWORD_SECOND=testuser@123

app/config/database.php

'connections' => [
    'onlineorder' => [
            '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'),
        ],
]

app/Models/OnlineOrder/OnlineOrder.php

<?php
namespace App\Models\OnlineOrder;
use Illuminate\Database\Eloquent\Model;

class OnlineOrder extends Model
{
    protected $connection = 'onlineorder';

}

app/Http/Controllers/Onlineorder/AppOnlineOrderController.php

<?php

namespace App\Http\Controllers\Onlineorder;

use Symfony\Component\HttpKernel\Exception\HttpException;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Input;
use App\Models\OnlineOrder\OnlineOrder;
use Illuminate\Http\Response;
use Illuminate\Http\Request;
use Carbon\Carbon;
use Validator;
use Config;
use File;
use DB;


class AppOnlineOrderController extends Controller
{
    public function test($merchant_id)
    {
        $db_ext = DB::connection('onlineorder');
        $merchant = $db_ext->table('mt_merchant')->get(); //mt_merchant is table name
        print_r($db_ext);exit;
    }
}

Simply i want to connect live server database in my local sever project

At the "Connectivty and Security" of your RDS instance page check if the configuration have "Public Accesibility" on "Yes" option. Maybe you don't have a public IP associated to your instance.
