Redirecting non-www to www in Nginx

Edit your virtualhost file and replace yourdomain.com with www.yourdomain.com and add this at the top:

server {
    listen 80;
    server_name yourdomain.com;

    return 301 http://www.yourdomain.com$request_uri;
}

Restart nginx:

sudo service nginx restart

Finally, add a CNAME record with the name of “www” and the hostname of “@”.

Thanks Kamal Nasser. Now it is working perfect.
