How to Enable HTTPS in Nginx
Enabling HTTPS (Hypertext Transfer Protocol Secure) on your Nginx web server is essential for securing your website, protecting user data, and improving SEO. This tutorial will guide you through the steps to enable HTTPS using an SSL/TLS certificate.
1. Installing Nginx
If you haven’t installed Nginx yet, you can do so using the appropriate package manager:
- For Ubuntu:
sudo apt update sudo apt install nginx - For CentOS:
sudo yum install nginx
2. Obtaining an SSL Certificate
To enable HTTPS, you need an SSL certificate. You can obtain a free certificate from Let’s Encrypt or purchase one from a certificate authority. To use Let’s Encrypt, first, install Certbot:
- For Ubuntu:
sudo apt install certbot python3-certbot-nginx - For CentOS:
sudo yum install certbot python2-certbot-nginx
Then, use Certbot to obtain and install the SSL certificate:
sudo certbot --nginxFollow the prompts to complete the installation.
3. Configuring Nginx for HTTPS
Once you have the SSL certificate, you need to configure Nginx to use it. Open the configuration file for your website:
sudo nano /etc/nginx/sites-available/example.comMake sure your server block includes the following configuration:
server {
listen 443 ssl;
server_name example.com www.example.com;
ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
root /var/www/example.com;
index index.html;
location / {
try_files $uri $uri/ =404;
}
}Don’t forget to replace example.com with your actual domain and adjust the root directory as needed.
4. Redirecting HTTP to HTTPS
To ensure all traffic uses HTTPS, configure a redirect in the existing HTTP server block:
server {
listen 80;
server_name example.com www.example.com;
return 301 https://$host$request_uri;
}5. Testing the Configuration
After making changes, test the Nginx configuration for syntax errors:
sudo nginx -tIf the output shows Syntax OK, you can restart Nginx:
sudo systemctl restart nginx6. Conclusion
By following this tutorial, you have learned how to enable HTTPS in Nginx to secure your web applications. Implementing SSL/TLS not only protects user data but also builds trust and enhances SEO.
