Will the Apache2 + PHP5(mod_php) + PHP7-FPM scheme work?

Question

PHP

Hello! Tell me, will the Apache2 + PHP5(mod_php) + PHP7-FPM web server scheme work if I have a large number of users and sites? Those. As far as I know, PHP-FPM runs as a specific user (www-data by default), and if all sites belong to different users, then what should I do in this case?

Answer 1

and if all sites belong to different users, then what to do in this case?

Set file permissions (in particular php files) so that FPM-PHP can at least read them.
In general, in the FPM mode, as many pools are usually created as there are users, and each of them works as its own user, and the problem is acc. disappears by itself.

Answer 2

Use docker.
There are 5 containers:
nginx-proxy working with upstream for 2 different sites
nginx container and php 5 for the first site
nginx container and php 7 for the second site
All this should be registered as docker services and run with 1 command.
And don't sweat it.
