Question Change php version on terminal

[Stergios G]

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.

[root@hs23 ~]# php --version

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.

[root@hs23 ~]# sudo dnf install php -y

Hi kaspar and thnx for reply.
Plz help me to understand. is /opt/plesk/php/7.4/bin/php a command for terminal which change php version?
Because when i type it terminal stop on cursor.

 

[Kaspar]

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.

 

[mow]

Do you have `update-alternatives --all` in AlmaLinux?

Thnx for your explanation, it was useful, but how to make a php 7.4 environment on terminal and run magento installation from web-brower?

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?

 

[Peter Debik]

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?

 

[Peter Debik]

That depends on what you have selected in the "Hosting Settings > Web Hosting Access > Access to the server over SSH" settings.

 

[Stergios G]

/bin

That depends on what you have selected in the "Hosting Settings > Web Hosting Access > Access to the server over SSH" settings.

Access to the server over SSH: /bin/bash

Another use posted detailed instructions on how to install Magneto 2.4 on Plesk. You can read those here: Instruction - How to Install Magento 2.4 on Plesk

Maybe it helps you with the installation process.
