```
ACMEDOMAIN=domainname.tld

/root/.acme.sh/acme.sh --standalone --issue -d www.${ACMEDOMAIN} -d ${ACMEDOMAIN} \
--cert-file /etc/ssl/${ACMEDOMAIN}-cert.pem \
--key-file /etc/ssl/${ACMEDOMAIN}-priv.pem \
--fullchain-file /etc/ssl/${ACMEDOMAIN}-fullchain.pem \
--pre-hook "nginx -s stop; killall nginx" \
--post-hook "nginx"
