# HTTPS - certbot (before first run): create ACME-challenge common directory

mkdir -p /var/www/_letsencrypt && chown www-data /var/www/_letsencrypt



# HTTPS - certbot (before first run): disable SSL directives

sed -i -r 's/(listen .*443)/\1;#/g; s/(ssl_(certificate|certificate_key|trusted_certificate) )/#;#\1/g' /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-available/mydomain.com.conf



# HTTPS - certbot: obtain certificates

certbot certonly --webroot -d example.com -d www.example.com --email [email protected] -w /var/www/_letsencrypt -n --agree-tos --force-renewal

certbot certonly --webroot -d mydomain.com -d www.mydomain.com --email [email protected] -w /var/www/_letsencrypt -n --agree-tos --force-renewal



# HTTPS - certbot (after first run): enable SSL directives

sed -i -r 's/#?;#//g' /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-available/mydomain.com.conf
