Resolved How can I connect php5.6 with mariadb10.6?

[federiklampo]

Server operating system version

cloudlinux 8

Plesk version and microupdate number

18.0.48

I'm having some problems regarding the connection of a php5.6 to mariadb 10.6; I thought it was a wrong configuration of the php.ini but it seems to be all correct.
i create a custom php_handler following the guide;
The error specific i get is this:

Warning: mysqli::mysqli(): (HY000/2002): No such file or directory in /var/www/vhosts/SITE/system/library/db/mysqli.php on line 7Warning: DB\MySQLi::__construct(): Couldn't fetch mysqli in /var/www/vhosts/SITE/system/library/db/mysqli.php on line 10Warning: DB\MySQLi::__construct(): Couldn't fetch mysqli in /var/www/vhosts/SITE/system/library/db/mysqli.php on line 10

here the list of the module my php5.6 version load:

# /opt/alt/php56/usr/bin/php -m
PHP Warning: PHP Startup: Unable to load dynamic library '/opt/alt/php56/usr/lib64/php/modules/nd_pdo_mysql.so' - /opt/alt/php56/usr/lib64/php/modules/nd_pdo_mysql.so: undefined symbol: pdo_parse_params in Unknown on line 0

PHP 5.6 doesn't support the mysqli function calls. There is a way to get around this, which I described in this post:

Resolved - How to install CentOS 8 Plesk 5 php version ?

Hi, I installed Plesk panel on Centos 8, but php 5x versions have been removed. How do I install it ?

talk.plesk.com

But it would be better to choose a more recent PHP version, like PHP 7.4 or higher.

Is much simpler than that, the global php.ini file of the alt-php56 pkgs is not configured correctly.
I don't know for what reason but the path to mariadb socket was missing.
These are usually default settings.
