HowTo: Nginx Redirect HTTP To HTTPS with Rewrite 301 Rules

To redirect HTTP traffic to HTTPS in Nginx, you can add the following rewrite rule in the server block of your Nginx configuration file:

server {
 listen 80;
 server_name example.com;
 return 301 https://$host$request_uri;
}

Replace example.com with your domain name.

This rule will listen for incoming HTTP traffic on port 80, and for all requests, it will return a 301 permanent redirect to the same URL with HTTPS.

Make sure you have a server block configured for HTTPS traffic and that you have a valid SSL certificate installed.

You can then restart Nginx to apply the changes:

sudo service nginx restart
