Connection refused when running Laravel artisan command with Docker

php mysql laravel docker docker-compose

Solution 1

First edit your docker-compose.yml.

mysql:
    image: mariadb:latest
    ports:
      - 8889:3306

After that set the correct DB port in .env.

Your DB port is wrong. You are trying to connect the exposed port inside the docker. In this case you should use DB_PORT=3306 in your .env.

Solution 2

this worked for me: put the name of my mysql container instead of 127.0.0.1

NAME CONTAINERS

project-db --> container mysql
project-app --> container laravel

DB_CONNECTION=mysql
DB_HOST=project-db
DB_PORT=3306
DB_DATABASE=project
DB_USERNAME=root
DB_PASSWORD=root

Solution 3

Try change port to 3306 and use DB_HOST=localhost to yourdomain.com(your IP)

And don't forget Sudo Clear cache and config cache

DB_HOST=My_ip_for_virtual_machine (yourdomain.com)
sudo docker-compose exec app php artisan config:clear
sudo docker-compose exec app php artisan cache:clear

Solution 4

After 5 hours researching I found this quote in comments:

Remove port-exposing, mariadb:latest sets it in its Dockerfile: This image exposes the standard MySQL port (3306)...

This mean you MUST use port 3306 in .env of each Laravel projects, either you define port for Mysql(or mariaDB).

This mean in host only port 3306 connect your Laravel to database.

I'm running Laravel 5.4 in Docker. This is my docker-compose.yml file:

version: '2'

services:
  app:
    container_name: laravel_app
    image: webdevops/php-apache-dev:ubuntu-16.04
    links:
      - mysql
    depends_on:
      - mysql
    ports:
      - 8888:80
    volumes:
      - .:/app
    environment:
      docker: 'true'
      WEB_DOCUMENT_ROOT: '/app/public'
      WEB_NO_CACHE_PATTERN: '\.(.*)$$'
      working_dir: '/app'
  mysql:
    image: mariadb:latest
    ports:
      - 8889:80
    environment:
      MYSQL_ROOT_PASSWORD: 'dev'
      MYSQL_DATABASE: 'dev'
      MYSQL_USER: 'dev'
      MYSQL_PASSWORD: 'dev'

This is the relevant part of my .env file:

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=8889
DB_DATABASE=dev
DB_USERNAME=dev
DB_PASSWORD=dev

I am able to see the Laravel welcome page - that side of things works. But when I run php artisan migrate I get this error:

SQLSTATE[HY000] [2002] Connection refused (SQL: select * from information_schema.tables where table_schema = dev and table_name = migrations)

I have tried fiddling with the host and port parameters in the .env file.

This is a typo question it should be removed, since OP failed to read hub.docker.com/_/mariadb.

If that rule was universally applied, SO would be a third of its current size. I'm not saying that's necessarily a bad thing...

Thank you!!!!!!!!!!!!!!!! This worked for me. Opened up Docker and copied the name of my mysql container: my-ap_mysql_1 and put it as the DB_HOST.

That's weird, it works but cost me days of searching for solutions. Thanks for saving me more days of googling :D

Do you know why this worked for you? It didn't work for me and I was wondering if there's any documentation

I also found this one true for me while using mysql:latest. Despite setting a custom port, only 3306 works.

This may not be the actual solution of question which OP asked, but this is solution of one of the most common mistake
