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
