I setup my docker mysql and phpadmin via
version: '3.2'
services:
mysqllocal:
image: mysql:8.0
container_name: container_mysqllocal
restart: always
ports:
- '6603:3306'
environment:
MYSQL_ROOT_PASSWORD: pass1234
MYSQL_ROOT_HOST: '%'
phpmyadmin:
depends_on:
- mysqllocal
image: phpmyadmin/phpmyadmin
container_name: container_phpmyadmin
restart: always
ports:
- '8080:80'
environment:
PMA_HOST: mysqllocal
UPLOAD_LIMIT: 3000000000
docker inspect container_mysqllocal and got '172.30.0.2'. However when I tried to connect mysql via SequelPro. It gives Connection Failed error. How do I connect mysql to my SequelPro / mysql workbench app, is there any configuration I've missed?
Below is the screenshot of my SequelPro connection:
have you tried to access mysql from your local machine with the port defined, in your config is 6603

so I'm new to docker and now I'm trying to connect my php, and adminer service to mysql service. Here is my docker-compose file.
version: '3.1'
services:
php:
build:
context: .
dockerfile: Dockerfile
volumes:
- ./html:/var/www/html
ports:
- 80:80
db:
image: mysql:5.7
volumes:
- ./mysql:/var/lib/mysql
environment:
MYSQL_ROOT_PASSWORD: root
MYSQL_DATABASE: test
MYSQL_USER: test
MYSQL_PASSWORD: test
ports:
- 3360:3306
adminer:
image: adminer
restart: always
ports:
- 8080:8080
After I ran the docker-compose up -d command, I opened adminer (localhost:8080) and fill the server field with 'db', username with 'test', password with 'test', database with 'test'. Then I clicked login but I got Connection timed out message, I can't login to the mysql service. The mysql service logs showed that the 'mysqld: ready for connections' already. Any ideas where I did it wrong? thank you :)
I am using the following docker configuration:
version: "3"
services:
database:
image: mysql
ports:
- "3306:3306"
environment:
MYSQL_ROOT_PASSWORD: 1009
restart: "always"
phpmyadmin:
image: phpmyadmin
ports:
- "8080:80"
environment:
PMA_HOST: database
restart: "always"
depends_on:
- database
It works, but if I change the mysql port for my PC to - "3360:3306" (for example 3306 may be busy with the main mysql service running on the computer) - it stops working. If I do this, I will be able to connect to mysql from my computer in CMD like mysql -u root -P 3360 -p, but phpmyadmin will give the error - connection refused.
No matter what I do, I see this error. For example I used the following docker configuration:
version: "3"
services:
database:
image: mysql
networks:
- my-network
ports:
- "3360:3306"
environment:
MYSQL_ROOT_PASSWORD: 1009
restart: "always"
phpmyadmin:
image: phpmyadmin
links:
- database
networks:
- my-network
ports:
- "8080:80"
environment:
PMA_HOST: database
PMA_PORT: 3360
restart: "always"
depends_on:
- database
networks:
my-network:
Even all of this didn't work. Phpmyadmin gave out one inscription when trying to connect - Connection refused all the time. But it still worked in the terminal.
Why can't I use a different port for phpmyadmin in docker?
At the moment, I'm trying to set up my docker-compose file to run multiple (two) Node.js API's.
The first Node.js server connects fine to the database.
The second Node.js server keeps throwing this error
original: Error: connect ECONNREFUSED 172.29.0.3:3307
So my question is how to run multiple Node.js API's in docker?
This is my docker-compose.yaml:
version: '3.7'
services:
ISAAC-floor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3306:3306"
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
ISAAC-sensor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3307:3307"
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
ISAAC-floor-back-end:
image: jjuless/isaac-floor-back-end
environment:
DB_HOST: ISAAC-floor-database
DB_USER: root
DB_PASSWORD: isaac
DB_DATABASE: isaac
DB_PORT: 3306
DB_DIALECT: mysql
ports:
- "3000:80"
depends_on:
- ISAAC-floor-database
ISAAC-sensor-back-end:
image: jjuless/isaac-sensor-back-end
environment:
DB_HOST: ISAAC-sensor-database
DB_USER: root
DB_PASSWORD: isaac
DB_DATABASE: isaac
DB_PORT: 3307
DB_DIALECT: mysql
ports:
- "3001:80"
depends_on:
- ISAAC-sensor-database
Mysql is always listening on port 3306 in each container, so if you want to have multiple mysql instances in the same host, you will need to map different host ports to the same guest port
Hence you will need to change your docker-compose file as follows
ISAAC-floor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3306:3306" # <-- HOST port same as GUEST port
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
ISAAC-sensor-database:
image: mysql
environment:
MYSQL_ROOT_PASSWORD: isaac
ports:
- "3307:3306" # <-- Notice here the GUEST port is the same as the first container!
volumes:
- ./sql-scripts:/docker-entrypoint-initdb.d
So whats wrong with this docker-compose.yml? It actually looks ok to me.
But when i try to log in to phpmyadmin on http://localhost:8080/index.php
i get errors:

Context:
Docker version 19.03.3

Update:
I added adminer as well and login also fails.
Mysql stderr shows:
[Warning] Aborted connection 9 to db: 'unconnected' user: 'unauthenticated' host: '192.168.32.3' (This connection closed normally without authentication)
I had the same error and fixed it by deleting the database volume and recreating the database. Not the nicest of solutions. The MySQL server was getting stuck on startup.
I had the luck of it being a database on a dev box so running migrations and reseeding with test data was all I had to do.
Each time when I try to access the phpmyadmin from browser I receive this error:
"Cannot log in to the MySQL server"
I tried to change networks, restart docker.

Your didn't mention if you're using the browser on the same computer as the sever or remotely. You'll need access to the mysql server (mysqld) through a terminal (command prompt). If this is a new install, it must be on the computer that is running mysql server.
In the Docker mysql page:
"The default configuration for MySQL can be found in /etc/mysql/my.cnf, which may include additional directories such as /etc/mysql/conf.d or /etc/mysql/mysql.conf.d."
Try looking in the /etc/mysql/my.cnf file on the server you're trying access. first. You're looking for:
bind-address = x.x.x.x
This is the address that the mysql server will talk to ("bound to"). Its typically "localhost" or "127.0.0.1".
To eliminate the error message like you see, I had to do two things:
1) change 'bind-address to 0.0.0.0'
this allows the server to connect to any computer. However, THIS IS A SECURITY RISK. Once you get it working, go read about bind addresses on the mysql website and set it appropriately.
2) Create an new account user#ipaddr where user is the new username and IPAddress is the ip4 address of the computer your trying to connect from. i.e.:
CREATE USER 'user'#'192.168.1.68' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON *.* TO 'user'#'192.168.1.68';
Now try accessing mysql through the terminal program using the new username on the computer with the ip you entered above by typing:
mysql -uuser -ppassword -hx.x.x.x
Hopefully, this will help point you in the right direction. There's a ton of information about bind addresses and security on the web.
Because the phpmyadmin container has connected to the default host localhost. But your mysql server is located in other container (it means you cannot connect to mysql server by using localhost). So in the phpmyadmin service, you have to set PMA_HOST=db. See full env variables: https://hub.docker.com/r/phpmyadmin/phpmyadmin/

If you are using phpmyadmin with latest mysql version you will have some login issues:
Cannot log in to the MySQL server mysqli_real_connect():
The server requested authentication method unknown to the client [caching_sha2_password] mysqli_real_connect(): (HY000/2054):
The server requested authentication method unknown to the client
The solution is to downgrade to mysql 5.7 or another.
I tested with mysql 5.7 and it works for me.
If you want to can test with another versions and let the community know.
Below is the docker-compose file that builds and run Nginx + php 7.1 + mysql 5.7 +phpmyadmin
