How to configure Nginx with Let's Encrypt on CentOS 7

To configure Nginx with Let's Encrypt on CentOS 7, follow these steps:

1. Install the Let's Encrypt client (certbot) and the Nginx plugin:

sudo yum install certbot python3-certbot-nginx

2. Obtain a certificate from Let's Encrypt using the certbot client:

sudo certbot --nginx

This will start the interactive certbot wizard, which will guide you through the process of obtaining a certificate. Follow the prompts to enter your domain name, email address, and agree to the terms of service.

3. Once the process is complete, certbot will automatically update your Nginx configuration to use the new SSL certificate.

4. Test your configuration by accessing your website over HTTPS. You should see the green padlock icon in your browser's address bar, indicating that the connection is secure.

That's it! Your Nginx server is now configured with a Let's Encrypt SSL certificate.

Note: If you need to manually specify the location of the Nginx configuration file, you can use the --nginx-server-root option. For example:

sudo certbot --nginx --nginx-server-root /etc/nginx
