CERTBOT🔗

Use a different port with multiple domains:🔗

certbot certonly --standalone --preferred-challenges http --http-01-port 8080 -d example.com,ww.example.com --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2

Removing a domain from a certificate (alias)🔗

You have a certificate called domain.dk. It has the following domains included in the certificate:

• domain.com
• domain.org
• domain.eu
• domain.us

You want to remove domain.us. To remove domain.us, you run below command. Notice how domain.us is omitted in the list.

certbot --cert-name domain.dk -d domain.com,domain.org,domain.eu

That’s it.
