How to change the version of php that the webserver is using?

Question

linux

ubuntu server 18.04 nginx

Installed all dependencies via composer
But the application swears that php version is needed >= 7.3

The command php -vshows php 7.4.22
phpinfo()shows 7.2.24 Can

you please tell me how can I change the php version?

Tried:

sudo a2dismod php7.2 ; sudo a2enmod php7.4 ; sudo service apache2 restart

Answer:

Module php7.2 already disabled
Considering dependency mpm_prefork for php7.4:
Considering conflict mpm_event for mpm_prefork:
Considering conflict mpm_worker for mpm_prefork:
Module mpm_prefork already enabled
Considering conflict php5 for php7.4:
Module php7.4 already enabled
Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xe" for details.

As you can see, the old version is turned off and the new version is turned on. But Apache won't restart. It is possible that I work through nginx
The command journalctl -xedisplays

Answer 1

Nginx does not know how to process php on its own, so it uses an "intermediary" (for example, fastcgi php-fpm). You can view the current "intermediary" through the phpinfo output (Server API field). You can configure the version by specifying the path to the desired socket in the fastcgi_pass directive.

Answer 2

Obviously, you have several versions of php installed at the same time, and the server uses a different version than the one you have in the console.
The php -i command will give you a console analogue of phpinfo, where you can see the path to php.ini . Commands like or , or constant
can also help (in the php console -r "echo PHP_BINARY;") . Most likely they will give out Then in the nginx config, specify the same binary that is used in the cli. whereis phpwhich phpPHP_BINARY
