这就是我为两个子域创建两个证书所运行的。
VPNHOST="vpn-i.example.com"
APIHOST="api-i.example.com"
certbot certonly --non-interactive --agree-tos --email $EMAIL --webroot -w /var/www/letsencrypt/api -d $APIHOST -w /var/www/letsencrypt/vpn -d $VPNHOST
According to the logs it has accepted both entries and has sent and received the challenge, but it has written the certificate only for api entry.
Saving debug log to /var/log/letsencrypt/letsencrypt.log
