I have generated SSL certificate like so:
sudo git clone https://github.com/letsencrypt/letsencrypt /opt/letsencrypt
./letsencrypt-auto certonly --standalone
Then I was asked for email … and a domain name. I entered ‘mydomain.com’
Could I have entered multiple domains when I was promoted for them in a dialog or now I need to regenerate using a different approach?
Do I need to remove previous letsencrypt installation before going new way?
