Step 1: Update Your System

Before you begin, make sure your Ubuntu system is up to date:

sudo apt update

sudo apt upgrade

Step 2: Install Nginx

If you don't have Nginx installed, you can do so using the following command:

sudo apt install nginx

After the installation is complete, start Nginx and enable it to start at boot:

sudo systemctl start nginx

sudo systemctl enable nginx

Step 3: Install Certbot

Certbot is a tool provided by Let's Encrypt to manage SSL certificates for your web server. Install Certbot and the Nginx plugin with the following command:

sudo apt install certbot python3-certbot-nginx

Step 4: Obtain and Install SSL Certificate

Now, you can use Certbot to obtain and install the SSL certificate for your domain. Replace `` with your actual domain name:

sudo certbot --nginx -d

Certbot will ask you a series of questions, including an email address for renewal reminders and agreeing to the terms of service. Follow the prompts to complete the certificate issuance process.

Step 5: Configure Nginx to Use the SSL Certificate

Certbot will automatically configure Nginx to use the SSL certificate for your domain. You can check the Nginx configuration by running:

sudo nginx -t

If there are no errors, reload Nginx to apply the changes:

sudo systemctl reload nginx

Step 6: Automatic Certificate Renewal

Let's Encrypt certificates are typically valid for 90 days, so it's important to set up automatic renewal. Certbot already creates a systemd timer for this purpose.

To test the renewal process, you can use the following command:

sudo certbot renew --dry-run

This command will simulate the renewal process. If it runs without errors, the automatic renewal should work as expected.

Step 7: Verify SSL Configuration

You can use online tools like SSL Labs' SSL Server Test to verify your SSL configuration:

This tool will provide a detailed report of your SSL configuration and security.
