LetsEncrypt Certbot SSL For Ubuntu

Install certbot using :

sudo apt-get install certbot python-certbot-nginx

Install the certificate using : (Replace mydomain.com with appropriate domain name).

sudo certbot --nginx -d mydomain.com -d www.mydomain.com

This command is so awesome that it :

1. Configures nginx (or apache) server for you.
2. Optionally configured nginx (or apache) to redirect all http traffic to https (You should always choose Yes when asked)
3. Configures auto renewal of the certificate.

It automatically adds an entry into crontab so that certbot is run twice daily. There is an entry under /etc/cron.d/certbot

Run the following to check the status of renewal service :

sudo systemctl status certbot.timer

Whats more

If the automated renewal process ever fails, Let’s Encrypt will send a message to the email you specified, warning you when your certificate is about to expire.

cron
docker
monit
nginx
