Configuring HTTPS on debian with Nginx and Let’s Encrypt is now really easy.
Let’s install required software :
sudo apt-get install certbot python-certbot-nginx
Then start the configuration process :
sudo certbot --nginx
And follow the steps :
Saving debug log to /var/log/letsencrypt/letsencrypt.log Which names would you like to activate HTTPS for? ------------------------------------------------------------------------------- 1: sub.mydomain.tld ------------------------------------------------------------------------------- Select the appropriate numbers separated by commas and/or spaces, or leave input blank to select all options shown (Enter 'c' to cancel):1 Enter email address (used for urgent renewal and security notices) (Enter 'c' to cancel):myemail@mydomain.tld ------------------------------------------------------------------------------- Please read the Terms of Service at https://letsencrypt.org/documents/LE-SA-v1.1.1-August-1-2016.pdf. You must agree in order to register with the ACME server at https://acme-v01.api.letsencrypt.org/directory ------------------------------------------------------------------------------- (A)gree/(C)ancel: A Obtaining a new certificate Performing the following challenges: tls-sni-01 challenge for mydomain.tld Generating key (1024 bits): /var/lib/letsencrypt/snakeoil/0000_key.pem Waiting for verification...

To enable redirect anyway, uncomment the redirect lines in /etc/nginx/sites-enabled/mydomain.tld. ------------------------------------------------------------------------------- Congratulations! You have successfully enabled https://sub.domain.tld You should test your configuration at: https://www.ssllabs.com/ssltest/analyze.html?d=sub.mydomain.tld ------------------------------------------------------------------------------- IMPORTANT NOTES: - Congratulations! Your certificate and chain have been saved at /etc/letsencrypt/live/sub.mydomain.tld/fullchain.pem. Your cert will expire on 2017-12-17. To obtain a new or tweaked version of this certificate in the future, simply run certbot again with the "certonly" option. To non-interactively renew *all* of your certificates, run "certbot renew" - If you lose your account credentials, you can recover through e-mails sent to myemail@mydomain.tld. - Your account credentials have been saved in your Certbot configuration directory at /etc/letsencrypt. You should make a secure backup of this folder now. This configuration directory will also contain certificates and private keys obtained by Certbot so making regular backups of this folder is ideal. - If you like Certbot, please consider supporting our work by: Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate Donating to EFF: https://eff.org/donate-le
If your want to redirect all HTTP traffic to HTTPS, uncomment the following line from your server configuration :
#Redirect non-https traffic to https
if ($scheme != "https") {
return 301 https://$host$request_uri;
} # managed by Certbot
