I am using Laravel 8.33.1 and mysql Ver 8.0.23-0ubuntu0.20.04.1 for Linux on x86_64 ((Ubuntu)) on my Ubuntu 20.04.1 LTS vps.

As during development I also need to access data from my production db. Within my code I do this the following way:

             $con = "mysql_prod";
            // $con = "mysql";

            // DB::connection($con)->enableQueryLog();
            $data = DB::connection($con)->table('test')->select('*')
                ->where('test.id', 'LIKE', '%' . $id. '%')
                ->get();

Therefore my prod .env file looks like the following:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=test_db
DB_USERNAME=root
DB_PASSWORD=
DB_SOCKET=/var/run/mysqld/mysqld.sock

DB_CONNECTION_PROD=mysql_prod
DB_HOST_PROD=127.0.0.1
DB_PORT_PROD=3306
DB_DATABASE_PROD=test_db
DB_USERNAME_PROD=root
DB_PASSWORD_PROD=
DB_SOCKET_PROD=/var/run/mysqld/mysqld.sock

However, I get the following error in my laravel application:

Illuminate\Database\QueryException Object
(
    [sql:protected] => select * from `products` where `products`.`owners` LIKE ?
    [bindings:protected] => Array
        (
            [0] => %sha:asdfsdafwaeadfasdfsadr%
        )

    [message:protected] => SQLSTATE[HY000] [2002] Connection refused (SQL: select * from `products` where `products`.`owners` LIKE %sha:asdfsdafwaeadfasdfsadr%)
    [string:Exception:private] =>

    [file:protected] => /var/www/test_project/vendor/laravel/framework/src/Illuminate/Database/Connection.php
    [line:protected] => 678
    [trace:Exception:private] => Array

My /var/log/mysql looks like the following:

Any suggestions what I am doing wrong?

Why can`t I use two socket connections to my mysql database?

I appreciate your replies!

  • @Colin'tHart: Could be a trick to preserve settings for an alernative configuration in the actual config file without making those settings active.
