Certbot is the command line tool for Let’s Encrypt, with it, you can
renew SSL certificates easily through simple commands.
While official guide telling people to install it with snapd, I found it more simple to install it via each Linux distributions’ onboard package manager.
So here we go…
Install On Ubuntu 20.04
sudo apt install certbot python3-certbot-nginx
Install On CentOS 7
sudo yum install epel-release
sudo yum install certbot python2-certbot-apache mod_ssl
