Secure NGINX On Debian Using Certbot

The below steps help us to secure NGINX on Debian using Certbot:

• Firstly, we’ve to access the server running the HTTP page with sudo privileges using SSH.
• Then install and set up snapd.

  sudo apt update
  
  sudo apt install snapd Install the core snap:
  
  sudo snap install core
  
  sudo snap refresh core
  
  
  

• Now we’ve to confirm the snapd is up-to-date.

  sudo snap install core; sudo snap refresh core

   
• We must now delete any Certbot packages installed using an OS package manager.

  sudo apt-get remove certbot
  
  sudo dnf remove certbot
  
  sudo yum remove certbot
  
  
  

• Now we’ve to install Certbot.

  sudo snap install --classic certbot

   
• We must make sure the Certbot command can execute by using the below code on the command line.

  sudo ln -s /snap/bin/certbot /usr/bin/certbot

   
• We can either get and install the certificates or just get the certificates.

  $ sudo certbot --nginx                            //To Install A Certificate

  $ sudo certbot certonly --nginx       //To Get A Certificate
• The system’s Certbot packages include a cron job or systemd timer that will automatically renew the certificates before they expire. Unless the configuration changes, we won’t need to run Certbot again. Run the following command to test certificate automatic renewal:

  sudo certbot renew --dry-run

   

  The following places have the command to renew Certbot installed:

  /etc/crontab/
  
  /etc/cron.*/*
  
  systemctl list-timers
• Finally, we’ve to make sure the Certbot worked and the site was set up properly by visiting https://ourwebsite.com/ in the browser and check for the lock icon in the URL bar.
