I can not connect to Mysql created with Docker in local environment (Mac OS X).
I have created the following configuration file.
version: '2'
services:
db:
image: mysql:5.7
environment:
MYSQL_DATABASE: mysqldatabase
MYSQL_USER: mysql
MYSQL_PASSWORD: mysql
MYSQL_ROOT_PASSWORD: password
ports:
- "33333:3306"
container_name: mysql-db
volumes:
- db-data:/var/lib/mysql
volumes:
db-data:
driver: local
Then, I started the docker container of mysql with the following command.
$ docker-compose up -d
$ docker start mysql-db
Up to this point there was no problem, but an error occurred when trying to connect to mysql.
$ mysql -p 33333 -u root -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Please tell me how to deal with it.
Try mysql -h 0.0.0.0 -P 33333 -u root -p.
Note port here has upper case P and password has lower case p.
Hope this helps!
I think if you connect from the host to the container. mysql will see the connection from non-local host, so disconnect it. You can change mysql config to allow other hosts, or connect from inside that container using docker exec -it mysql ...

I have the following docker compose:
version: '3.1'
services:
db:
image: mysql:5.5
container_name: mysql
environment:
- MYSQL_ROOT_PASSWORD=some_root_pw
- MYSQL_DATABASE=some_db
- MYSQL_USER=db_user
- MYSQL_PASSWORD=user_pw
ports:
- 8306:3306
volumes:
- ./db:/var/lib/mysql/some_db
I am accessing the container with the command:
docker-compose exec db /bin/sh
Which drops me at the shell as expected. However, I am unable to access mysql with the information from the docker-compose file.
mysql -u root -p
Prompts for the password, then rejects for bad username or password. I have tried with both root and user. Is there a way I can troubleshoot what is happening with user creation?
NOTE: intentionally older version of MySQL.
Let's say I have the following compose file :
networks:
my_network:
services:
...
mysql:
container_name: "mysql"
image: "mysql:5.7"
volumes:
- ./mysql.cnf:/etc/mysql/conf.d/mysql.cnf
environment:
MYSQL_ROOT_PASSWORD: "password"
MYSQL_USER: "user"
MYSQL_PASSWORD: "password"
MYSQL_DATABASE: "test-db"
ports:
- "3306:3306"
restart: always
networks:
- my_network
Once I run docker-compose up, my services get started and I can see that my MySQL server is ready to accept connections. Now what do I need to do to access the mysql terminal prompt from "outside" the container ? I remember seeing a teacher run another docker container (from a new terminal), and access the MySQL command prompt, enabling him to manage the database by hand, from another terminal window, but I can't remember the command exactly.
I tried running a new Docker container like this :
docker run -it --rm --name mysqlterm \
--network="compose_project_my_network" \
--link mysql mysql:5.7 \
sh -c 'exec mysql \
-h "localhost" -P 3306" \
-uroot \
-ppassword'
But unfortunatly, the container can't connect to the MySQL server, giving me the following error : ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2).
I guess the "localhost" or 3306 port are wrong ? What should I put in these parameters ?
Thanks in advance for your answers :)
You need an ordinary MySQL client; if your host's package manager (Debian/Ubuntu APT, MacOS Homebrew, ...) has a packaged named something like mysql-client, that's it.
When you run mysql, that tool does not interpret localhost as a host name but rather as a signal to use a Unix socket, so you need to use the corresponding IP address 127.0.0.1 instead. (If the database is running on a different system, use its DNS name or IP address: this is indistinguishable from running the database directly on the host outside of Docker.)
So from the host run:
mysql -h 127.0.0.1 -u root -p
The default port 3306 matches the published ports:, and you'll be prompted to interactively enter the password.
I created mysql docker container
docker run -p 13306:3306 -d -e MYSQL_ROOT_PASSWORD="pass" -e MYSQL_DATABASE="db" --name mysql mysql:5.6.46
and I tried to connect to mysql
mysql -u root -p -h localhost -P 13306
but I can't connect to mysql.
ERROR 1045 (28000): Access denied for user 'root'#'localhost' (using password: YES)
I must connect like this for some reason. not use docker exec -i -t mysql bash
you should try and expand your question a bit and add some more information about the errors you receive.
In my local development environment in order to connect to my MySQL database I give it a static ip address. I tend to use docker-compose and not run it from the docker command directly for simplicity. This is what my docker-compose.yaml file looks like for a mariaDB container :
version: '3.7'
services:
maria:
container_name: maria
image: mariadb:10.4
restart: always
environment:
- MYSQL_ROOT_PASSWORD=password
- MYSQL_USER=user
- MYSQL_PASSWORD=user_password
volumes:
- ./maria:/var/lib/mysql
networks:
static:
ipv4_address: 172.30.0.10
networks:
static:
ipam:
driver: default
config:
- subnet: 172.30.0.0/16
After running the docker-compose up command I can now connect to the mysql shell with the command
mysql -uuser -puser_password -h 172.30.0.10
if you are running linux you can also add a line to your /etc/hosts file like :
172.30.0.10 mysql
you can then connect with the command
mysql -uuser -puser_password -h mysql
I'm pretty confident you can get the same results with a pure docker command but it just seems easier with docker-compose. Anyway I hope ths helps
I already executed mentioned here: Unable to connect to MYSQL from Docker Instance, but this time I'm running docker on windows machine.

You should try to connect through the loopback interface, as you don't have access to the socket.
mysql -h 127.0.0.1 -uroot -p
In this case, it's like if your server is running on another machine, this only thing share with your host machine is the exposed port.
If you download the MySQL client from https://dev.mysql.com/downloads/windows/ then you'll be able to access the Docker-hosted MySQL in the same way you'd access any other MySQL database (of note without needing to get a root shell in the database container). Since you're using Docker Toolbox you'd probably use 192.168.99.100 as the IP address of the database server.
Try adding below in docker-compose.y\ml
services:
db:
image: mysql:5.7
environment:
MYSQL_DATABASE: 'Dbname'
# So you don't have to use root, but you can if you like
MYSQL_USER: 'username'
# You can use whatever password you like
MYSQL_PASSWORD: 'Password'
# Password for root access
MYSQL_ROOT_PASSWORD: 'RootPassword'
ports:
# <Port exposed> : < MySQL Port running inside container>
- '3307:3306'
expose:
# Opens port 3306 on the container
- '3306'
# Where our data will be persisted
volumes:
- my-db:/var/lib/mysql
volumes:
my-db:
I'm using the official MySQL image from docker hub and expose ports 3333:3306 to connect from outside.
I know that I have to change the bind IP inside /etc/mysql/my.cnf to the IP of this container and grant permission for a user like: GRANT ALL PRIVILEGES ON * . * TO 'newuser'#'container_ip'; so I can connect to this container by:
mysql -h container_ip -u root -p
But I received this error
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
Btw, I also try to connect from WordPress in another container but it cannot establish the connection. Here is docker-compose.yml
version: '2'
services:
mysqldb:
image: mysql:5.6
environment:
MYSQL_ROOT_PASSWORD: password
volumes:
- ./mysql-data:/var/lib/mysql
- ./mysql-import-data:/import-data
ports:
- "3333:3306"
blog:
image: webdevops/php-nginx:ubuntu-14.04
environment:
WEB_DOCUMENT_ROOT: /usr/share/nginx/html
volumes:
- ./blog:/usr/share/nginx/html
ports:
- "8080:80"
depends_on:
- mysqldb
What's the mistake I made with this mysql container? I cannot connect to it.
The IP of the container may change every time docker-compose up. How can I configure it?
Hmm I'm a little confused. From the point of view of the host os, the docker container is bound to one or more network interfaces. In your compose file you are exposing port 3333 to the host. That's what you have to connect to.
Plus you need to use an IP address, otherwise the mysql client will try to connect with a unix socket.
mysql -h 127.0.0.1 --port 3333 -u root -p
If you are trying to connect from inside your blog container then you can use mysqldb as your host with the 3306 port.
