Restart a service and check the result

caution rootsystemddebian, ubuntu

Caution: This command changes the system. Understand what it does before you run it.

Adjust the values, the command updates live
root@server
systemctl restart php8.2-fpm && systemctl is-active php8.2-fpm

Restarts the service and then reports active if it is running. If the restart fails, the error message from systemctl appears instead. The service is briefly unavailable during the restart.

Note: Many services support systemctl reload, which rereads the configuration without interruption. Before restarting Apache or nginx, test the configuration with apachectl configtest or nginx -t. Plesk’s own PHP versions are named plesk-php82-fpm and so on.
