Ubuntu 18.04. Nginx.
The server used to be hosted by Laravel Forge. Now - no, in free swimming. There were no changes on the server - everything that was created and configured by Forge remained.
I see the PHP 8.1 version is installed along the path /usr/bin/*php8.1. How can I change the php version now? Directly on the server without the Forge web interface. Thanks.
In Terminal
sudo update-alternatives --config php
will display all versions installed, choose a number selection if you want a version
There are 3 choices for the alternative php (providing /usr/bin/php).
Selection Path Priority Status
------------------------------------------------------------
* 0 /usr/bin/php8.0 80 auto mode
1 /usr/bin/php7.2 72 manual mode
2 /usr/bin/php7.4 74 manual mode
3 /usr/bin/php8.0 80 manual mode
Press "enter" to keep the current choice[*], or type selection number: 2
update-alternatives: using /usr/bin/php7.4 to provide /usr/bin/php (php) in manual mode
check current php version
php --version
