Restart all daemons

Sometimes a (directadmin) server runs out of swap space. It’s nice to know which service exactly is causing it but sometimes you do not have the time. A fast option to restart all services without having to figure out exactly which services you’ve got running (especially now that there’s the possibility of using 4 different versions of PHP).

# Specifically for directadmin/custombuild and CentOS
# Detects (some) options and restarts daemons, then
# shows free swap space

	}

# Detect running php-fpm instances, restart
for PHP in `systemctl | grep php-fpm | awk -F . '{print $1}'`; do
	echo Restarting $PHP
        systemctl restart $PHP
