The problem is that php container can't connect to mysql.
Although from host I can connect with mycli -h 127.0.0.1 -P 3306 -u root.
But when I exec in php container and try it, get 'Connection refused'
Your mysql service binds mysql server's port 3306 to 3306 of the host machine. Thus is it normal that you can connect from host.
From inside php container, localhost is referring to that particular container as #David Maze said in the comments.
Since you are using docker-compose containers are in the same network, so you should use the service name in order to connect to the mysql server.
Try this from php container:
mycli -h mysql -P 3306 -u root
You are able to connect with user root. But in your docker-compose file, you are connecting through user dbuser. Let me know if that's not the issue.
Usually conenction refused you get when request is coming from the different ip than it's bind-address. Try below should work.
Make sure mysql configuration my.cnf or whatever default configs doesn't block connect from outside(check
bind-address in the mysql configuration if it 127.0.0.1 the its only
allow to connect form locally, i would for now make it 0.0.0.0 or
commented that line if exists)
mysqld --verbose --help => you will see all options
mysqld --verbose --help | grep bind-address => check the bind-address
Make sure the user i tried to login has enough privileges to
connect(SELECT user,host FROM mysql.user;) check your user can
connect from docker network => 172.* or anywhere=> %
It may be possible due to cached volume.
Try deleting your volume:
$ docker volume prune

I have created an nginx container that is open to port 8080:80
so I could access it from the host.
it is connected to php fpm container that has an open port 9000:9000
nginx successfully runs with php.
My problem is that php tries to access localhost:8080
but the problem is that the php localhost:8080 is not valid, it needs to connect to the nginx container.
here is the error on my wordpress site:
you can see that something is funky there...
below I'll attach my docker-compose.yml

Use docker's internal networking and configure php to access http://my-nginx:80.
localhost will resolve to the isolated IP of the php container itself, not that of the Docker host that's running everything. And trying to pass http://dockerhost:8080 will result in a non-portable docker-compose.yml and likely issues with iptables firewall and nat rules that are more trouble than they are worth. The value of using the v2 compose files is that you get an isolated network internal to Docker with DNS resolution of each of your containers to work with each other.
My question is how to configure connection to mysql container.
Here is my docker-compose.yml
version: '3'
services:
php:
build: ./php-fpm
volumes:
- ./iym:/var/www/iym
- ./php-fpm/php.ini:/usr/local/etc/php/php.ini

mysql:

restart: always
command: --default-authentication-plugin=mysql_native_password
volumes:
- ${DB_PATH_HOST}:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: "symf0ny"
ports:
- "3306:3306"
And here is my DATABASE_URL in .env file
DATABASE_URL=mysql://root:symf0ny#127.0.0.1:3306/iym
When i try to run php bin/console doctrine:database:create i get an error like "SQLSTATE[HY000] [2002] Connection refused". OS - ubuntu 18.04. What should i do to connect to DB? Many thanks!
I assume you are trying to connect from another container/service defined in docker-compose and you are using current version of docker-compose (2.4 or 3.7)
You need to change
DATABASE_URL=mysql://root:symf0ny#127.0.0.1:3306/iym
to
DATABASE_URL=mysql://root:symf0ny#mysql:3306/iym
The reason is that 127.0.0.1 is refering to the localhost of the machine on which php runs. In this case it's the php's container localhost. But the db doesn't run there. It runs in another docker container, which can be reached under the service name, mysql in this case.
In docker-compose networking docs is written:
By default Compose sets up a single network for your app. Each container for a service joins the default network and is both reachable by other containers on that network, and discoverable by them at a hostname identical to the container name.
but, the service is discoverable under the container name (which is automatically generated to projectName_serviceName_1 (project name begin by default folder name), but also under service name, link and service alias if defined. I would recommend using service name wherever possible.
More in docs: https://docs.docker.com/compose/networking/
In my case, the Docker variable overrides the parameter from .env file and I'm trying to connect to the wrong host. Found that via dd($this->constructPdoDsn($params)) in the Doctrine\DBAL\Driver\PDO\MySQL\Driver::connect, maybe it will be helpful
I was trying out Docker for the first time. Got a LEMP stack up and running, but I can't connect to the MYSQL Database. Not on my Symfony application, not on PHPMyAdmin. The applications are returning the following error code:
An exception occured in driver: SQLSTATE[HY000] [2002] Connection refused

Could someone help me out? Thank you for your time.
The '[2002] Connection refused' means you can reach the database server, but you don't have right access for the user (in your case admin). By default mariadb have a root user with the password given by MYSQL_ROOT_PASSWORD and this user can connect from any server (%).
If you want use an over login to your databases, you have to create it in the databases server with the right granting on databases from chosen locations.
The problem here is that you have named your database server as 'mysql' (service name in the docker-compose file). But by default phpmyadmin tries to connect to a database server named 'db'. Adding PMA_HOST: mysql under the environment section of the phpmyadmin service will resolve this problem.
I think that MYSQL_USERNAME and PMA_ARBITRARY are useless if you work with default configuration (connection with root to your databases server)
I had this challenge because I am running 3 different containers with different IP Addresses
db - 172.18.0.3 - container for MYSQL
app - 172.18.0.2 - container for Laravel app
so I fixed it by editing my Laravel .env file
DB_CONNECTION=mysql
DB_HOST=172.18.0.3
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=username
...
To get your containers Ip addresses. From your docker host
docker inspect -f '{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)
UPDATED:
For latest docker versions and based on the services name, "mysql", in your docker-compose.yml
mysql:
image: mariadb
ports:
- 3306:3306
You can try this:
DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=username
DB_HOST is the name of MySQL service name defined in docker-compose.yml
I've managed to connect to the mysql instance using mysql command line tool, this is the command I used - mysql -u root -p -h 127.0.0.1, and the entering the admin password. Is that a sufficient solution for you?
In my case I was running mysql in a docker container whose port was mapped to the host mac (3306:3306). I tried connecting to this database from a phpmyadmin docker container using 127.0.0.1 . But it won't work because the localhost on the phpmyadmin docker container does not have the required mysql running.
To connect to the host from docker network
docker.for.mac.host.internal
Docker Networking Docker Compose Networking
For my instance, the issue was with port mapping somehow.
In my case it was 3307:3306, as soon as I changed it to 3307 on the right side as well, I could connect to the DB instance.
Adding DB_READ_HOST=db solved this problem for me
If you want to know why your connexion failed, you can use in your terminal php artisan tinker and then
like
DB::connection()->getPdo();
Unfortunately this will only give you a part of the error.
Quit tinker and then use this command php artisan db will give you more information like database type, host, port, ad user about the issue.
Like this one
ERROR 2003 (HY000): Can't connect to MySQL server on '127.0.0.1:3306' (61)

This will not give you the answer on what is wrong, but at least you can understand why your config is wrong.
you need to link the phpfpm container to mysql.
I have some configuration in docker-compose.yml file.
nginx:
image: nginx:latest
ports:
- 8083:80
links:
- php
volumes:

MYSQL_DATABASE: reportal
MYSQL_USER: reportal
MYSQL_PASSWORD: reportal
And when I try to run docker-compose up -d I got this error message:
C:\docker\reportal>docker run --name reportalnginx -v /c/xampp/htdocs/Drukwerk/rePortal:/var/www/html:ro -v /nginx/default.conf:/etc/nginx/conf.d/default.conf:ro -P -d nginx
docker: Error response from daemon: Conflict. The name "/reportalnginx" is already in use by container 2e7427b8dd13515c9868cceb31e56b7cd10626feff7a561c1bc19eeaa1158f1c. You have to remove (or rename) that container to be able to reuse that name..
See 'docker run --help'.
But when I remove line with config file path for nginx - it works normal.
Also I've been trying to use hint from this question:
Question Link
I was able to run nginx, but volumes wasn't connected.
How I can solve this kind of problem?
try to remove all containers
docker rm -f $(docker ps -a -q)
and run again. or check you nginx in system. maybe you can stop it.
I've got docker-compose file for creating mysql image and expose port to 3306, but when I try to install CMS, it gives me error that it can't connect to Database. I try to scan port 3306 and it's showing me that it's open so mysql is running.
Why the two of docker containers can't see each other ?
Here is my docker-compose file:
phpfpm:
restart: always
extends:
file: php-fpm-5.6.yml
service: phpfpm
links:
- db:db
nginx:
restart: always
image: nginx
ports:
- "8000:80"
links:
- phpfpm:phpfpm
volumes:
- ./nginx/vhost.conf:/etc/nginx/conf.d/default.conf
- ./app:/var/www/html
- ./log/nginx:/var/log/nginx
db:
restart: always
image: mysql
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: 123456
MYSQL_USER: user
MYSQL_PASSWORD: password
MYSQL_DATABASE: database
To connect to the database, use the link/alias you provided as a hostname. So, you CMS can connect to MySQL using db as hostname, and port 3306.
You won't be able to connect to localhost or 127.0.0.1, because "localhost" is the localhost inside each container, so, using "localhost" in the phpfpm container will try to connect to a MySQL database inside the phpfpm container, but there's no server running there.
Note that you don't have to publish ("3306":"3306") the MySQL ports if you only connect to the database from inside the linked containers. Publishing the ports exposes MySQL on the public network interface, which may be "the Internet"
