How to generate Let's Encrypt Certificate using Certbot on Amazon Linux 2

If you already have Certbot installed on Amazon Linux 2, then generating Let’s Encrypt shouldn’t be a problem. Let’s see what’s the solution.

Prerequisites

Make sure that your domain name is pointed to your Amazon Linux 2 instance’s IP address. You can check this by running the following command:
```
host your_domain_name
```
The above command should return your instance’s IP address. Once that sorted you can generate Let’s Encrypt certificate by running the following command:
```
sudo certbot --nginx -d your_domain_name
```
Certbot will automatically configure NGINX to use the new certificate. You can confirm that the configuration was successful by running the following command:
```
sudo nginx -t
```
Restart NGINX to apply the new configuration with the following command:
```
sudo systemctl restart nginx
```
