How to install mysql driver for php5.4 in isp manager?

Question

PHP

Hello!

A little introductory:
Debian 10 server, isp manager installed

There are several versions of php php7.4 as the main one, php7.2 and php5.4 for two very old projects on Bitrix (which cannot be updated)

The server is new, I just configured and migrate projects to it . Migration Occurs from a similar server, there is Debian 9 and isp.

The problem is that there is no mysql in the list of extensions for php5.4.

I tried to take the mysql.so file from /opt/php54/lib/modules of the old server and put it in the same directory on the new one (by creating mysql.ini in php.d)

But when I restart php-fpm54, the mysql driver does not work and

service php-fpm54 status

gives

[29-Mar-2020 00:22:14] NOTICE: PHP message: PHP Warning: PHP Startup: Unable to load dynamic library '/opt/php54/lib/php/modules/mysql.so' - libmysqlclient.so.18 :

Maybe someone faced a similar problem or knows how to solve it, I really count on you!
