Install LetsEncrypt certificate

Today I installed LetsEncrypt certificate on one of the production server.

I can not believe it is so simple to secure a website running on an Ubuntu server

sudo apt-get install certbot python-certbot-nginx
sudo certbot --nginx -d -d

It even configures nginx (or apache) server for you.

To manually renew run the following:

certbot renew --quiet

But you don’t have to, cause certbot is so awesome that it automatically adds an entry into crontab so that certbot runs 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


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.
