Cannot create a connection in test installation

Q&A
1

Hello,

Sorry if this is a silly question, but I’m trying to evaluate Atrocore and I’m completely new to it.

I made a test installation using docker compose as explained in the documentation.

When I try to create a connection to a MySql DB (running in a container as well), if I click on “test connection” I get an error that just says “500”, without any other detail.

I could not find other details about this error looking at the network tab with the browser’s developer tools, nor running podman logs.

What should I check to troubleshoot the creation of the connection?

Is there maybe something obvious that I’m overlooking?

Thanks!

Hi Alex,

I’ve found the logs under /var/www/localhost/data/logs, and I see this error when I try to create a connection:

[2025-12-08T12:09:09.240267+00:00] Log.ERROR: Uncaught Exception Error: “Undefined constant PDO::MYSQL_ATTR_INIT_COMMAND” at /var/www/localhost/vendor/atrocore/core/app/Atro/ConnectionType/ConnectionMysql.php line 31 {“exception”:“[object] (Error(code: 0): Undefined constant PDO::MYSQL_ATTR_INIT_COMMAND at /var/www/localhost/vendor/atrocore/core/app/Atro/ConnectionType/ConnectionMysql.php:31)”}

I tried uncommenting this line in /usr/local/etc/php/php.ini:

extension=pdo_mysql

and restart apache, but it doesn’t seem to change anything.

Do you have any suggestions?

Thanks!
