phpMyAdmin can't connect to mysql - both on same network.

[tcconway]

Somewhat new to Docker, so it might be a user error...

After having following several YT tutorials, I cannot get PHPMyAdmin to actually log in--I get the following errors:

• mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known
• mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known

My setup is: Docker with the default Laravel setup. Both 'mysql' and 'phpmyadmin' are in the 'sail' network.

Here's my docker-compose.yml:

Apparently setting - PMA_ARBITRARY=1 in the yml and then using 'mysql' during login works...

Apparently setting - PMA_ARBITRARY=1 in the yml and then using 'mysql' during login works...

What about using

       environment:
            PMA_HOST: mysql
            PMA_PORT: 3306

it should work fine

[tcconway]

It's not working with PMA_HOST and PMA_PORT.

Having this...

        environment:
            - PMA_HOST = mysql
            - PMA_PORT = 3306

...doesn't work. I get the following errors when trying to log in: mysqli::real_connect(): php_network_getaddresses: getaddrinfo failed: Name or service not known mysqli::real_connect(): (HY000/2002): php_network_getaddresses: getaddrinfo failed: Name or service not known

When I use this...

        environment:
            - PMA_ARBITRARY=1

... I can type 'mysql' into the Server field and it allows me to log in.

Perhaps 'mysql' is not unique enough?

[williamdes]

Hi,

This is a bit strange, can you try the format I sent you to be sure this is not the cause of this issue ?

            PMA_HOST: mysql
            PMA_PORT: 3306

Perhaps 'mysql' is not unique enough?

It's just a name, phpMyAdmin will not complain about it ;)

[gabrielmustiere]

hey, same problems here, same network, and two syntax try

What is your docker compose file?

[gabrielmustiere]

i have found the solution, juste remove PMA_PORT: 3306, only the host is enough

[jaggersystems]

The workaround for me was to use the local address of the docker host 10.10.10.x. Using the hostname would fail... I'll have to work out why the host couldn't resolve.

[williamdes]

I'll have to work out why the host couldn't resolve.

What is the host ?

Is it external on the computer name ?

Local. I have the db and docker/phpmyadmin running on the same host.
