what is the best solution to give phpmyadmin some specific php.ini values ? I tried editing /etc/phpmyadmin/apache.conf but the php admin values aren't used by php7.4-fpm what can be done ?
If using php-fpm you would create another conf file in /etc/php/7.4/fpm/pool.d/ for phpmyadmin, then adjust your apache config to use that correct socket (specified in the conf file) to talk to that fpm pool.
thanks for the hint. I'm afraid I'm not skilled enough to translate your description into commands. I'm not even sure why my phpmyadmin uses FPM. But I think it would be great to have a specific php.ini for the exclusive use of phpmyadmin.
That can be achieved by creating a website, installing phpmyadmin there and using Website Options in ISPConfig Panel. I'm not sure this is a good idea, why do you need to give PHPmyadmin those special settings?
I need to give my phpmyadmin much larger resources to perform database operations that can take several minutes to complete and use large import/export files (up to 100MB in zipped form). I feel these settings would be unsafe for general PHP use.
