Certbot will enable mod_ssl, add SSL virtual host, and optionally configure HTTP→HTTPS redirect.

Step 3 – Verify

apachectl -t && systemctl reload apache2
curl -I https://example.com

Step 4 – Auto-renewal

0 3 * * * certbot renew --quiet --deploy-hook "systemctl reload apache2"

Step 5 – Wildcard certificate (DNS challenge)

certbot certonly --manual --preferred-challenges dns \
    -d "*.example.com" -d example.com

Add the TXT record to DNS as instructed, then complete the challenge.
