Question Change php version on terminal

Stergios G

Stergios G

Basic Pleskian
Server operating system version
AlmaLinux 8.7
Plesk version and microupdate number
18.0.49
Ι am try to install Magento 2.4 on a new Plesk subscription. Magento 2.4 need php7.4 or higher for installation.
Plesk subscription is set to php7,4.

But i get the error: Magento supports PHP 7.4.0 or later. Please read Magento System Requirements.

I soon understood (In terminal) that the php version is 7.3.

An i wonder...
why on php --version i have php7.3.33, on php module list: default php7.2 and how can i change php version on 7.4?

ok for the first two i have a theory, but how to toggle between php versions?
 
Instead of using PHP command in the command line use /opt/plesk/php/7.4/bin/php to run PHP version 7.4 (if installed on you're server). Change the version in the command according to your need.

The PHP command runs the default PHP version that ships with your OS.
 
Because I have read many post... I tried to install last PHP on AlmaLinux/Rocky from Remi Repo.
Code: 
[root@hs23 ~]# sudo dnf install php -y

It's a replacement command for running a specific PHP version. So instead of running php bin/magento cache:clean you'd run /opt/plesk/php/7.4/bin/php bin/magento cache:clean for example.

Peter thnx for your reply, this was the first guide I read. But i have some problems on many steps, i suppose i must fix those first.

It will be a long road..
 
Hi again.
Sorry but i can not understand.
Why i need configure a specific command line PHP version and not entire server?
Why a magento installation do not use subscription php version and extensions?
How to know if i am in chrooted or non-chrooted environment? i tried to follow "How to configure a specific command line PHP version for an SSH user on a Plesk for Linux server?" guide and i have errors on any command on terminal.

How to start the debugging? Would you like me to post all the commands and results from the guide here?
 
You need to be logged in as "root" on your server in order to being able to apply the commands from the article, because this changes the configuration of your server.

But i am root user, which of two paths i must follow? chrooted or non-chrooted?
 
That depends on what you have selected in the "Hosting Settings > Web Hosting Access > Access to the server over SSH" settings.
