iPurpl3x Now I understood the concept, that's why I didn't explain myself too well in the question, it was for lack of knowledge I had no idea how ENV var worked in Linux, I thought it was something specific for this extension, another thing learned, thanks!
luceos That's very interesting, so I wouldn't forget/lose the configuration if I migrate server
So it would be something like this in the config.php
?
<?php return array (
// all the flarum stuff
);
REDIS_DATABASE_QUEUE=4
