SSL Certificate

1. SSH into the server

SSH into your HTTP website server as a user with sudo privileges.

2. Install snapd

You'll need to install snapd and make sure you follow any instructions to enable classic Snap support.

Follow these instructions on snapcraft's site to install snapd.

3. Remove certbot-auto and any Certbot OS packages

If you have any Certbot packages installed using an OS package manager like apt, dnf, or yum, you should remove them before installing the Certbot snap to ensure that when you run the command certbot the snap is used rather than the installation from your OS package manager. The exact command to do this depends on your OS, but common examples are:

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

4. Install Certbot

Run this command on the command line on the machine to install Certbot.

sudo apt update && sudo apt upgrade -y
sudo snap install --classic certbot

Prepare the Certbot command.

Execute the following instructions on the command line on the machine to ensure that the certbot command can be run.

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

5. Choose how you'd like to run Certbot

Either get and install your certificates...

Run this command to get a certificate and have Certbot edit your Apache configuration automatically to serve it, turning on HTTPS access in a single step.

sudo certbot --apache

Or, just get a certificate

If you're feeling more conservative and would like to make the changes to your Apache configuration by hand, run this command.

sudo certbot certonly --apache

6. Test automatic renewal

The Certbot packages on your system come with a cron job or systemd timer to renew your certificates automatically before expiring. You will not need to run Certbot again unless you change your configuration. You can test automatic renewal for your certificates by running this command:

sudo certbot renew --dry-run

The command to renew certbot is installed in one of the following locations:

• /etc/crontab/

• /etc/cron.*/*

• systemctl list-timers

7. Confirm that Certbot worked

To confirm that your site is set up properly, visit https://yourwebsite.com/ in your browser and look for the lock icon in the URL bar.

Remember to change to https in your redirects you set up earlier here​ and in the cofig.js.
