Switching PHP Versions

Webinoly makes it easy to switch between PHP versions:
1

Check Current Version

php -v
# or
sudo stack -info
2

Switch to New Version

sudo stack -php-ver=8.3
This command will:
  • Back up your current configuration
  • Remove the old PHP version
  • Install the new PHP version
  • Restore your configuration
  • Reinstall associated tools
3

Verify New Version

php -v
sudo systemctl status php8.3-fpm
Important: Switching PHP versions will:
  • Preserve your PHP configuration settings
  • Reinstall phpMyAdmin if installed
  • Reinstall Redis, Memcached, and Postfix if installed
  • May require brief downtime during the switch

​
PHP-FPM Configuration

​
Main Configuration File

PHP configuration is located at: 
/etc/php/8.4/fpm/php.ini

​
Troubleshooting

Check configuration and socket:
sudo php-fpm8.4 -t
ls -la /run/php/
sudo journalctl -xe
Increase PHP memory:
sudo nano /etc/php/8.4/fpm/php.ini
# Change memory_limit
sudo systemctl reload php8.4-fpm
Check both NGINX and PHP limits:
# PHP settings
php -i | grep upload_max_filesize
php -i | grep post_max_size

# NGINX setting
grep client_max_body_size /etc/nginx/nginx.conf
Manually complete the process:
sudo stack -php -purge=force
sudo webinoly -config-set=php-ver:8.3
sudo stack -php
