I have bought a SSL certificate for my domain. How could I install this certificate and redirect all HTTP requests to HTTPS on Nginx web server?

Answer: we can easily rewrite/redirect all HTTP requests to HTTPS with Nginx web server. The syntax is as follows. We need to add the following in location or server directives:

Rewrite syntax

return         301 https://$server_name$request_uri;

Configuration file example

    server {

        listen 80;
        server_name r00t4bl3.com;
        access_log off;
        error_log off;
        return      301 https://$server_name$request_uri;
    }

    server {

        listen 443 http2 ssl;
        server_name r00t4bl3.com;
        ssl_certificate /etc/letsencrypt/live/r00t4bl3.com/fullchain.pem;
        ssl_certificate_key /etc/letsencrypt/live/r00t4bl3.com/privkey.pem;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_session_cache shared:SSL:10m;
        ssl_session_timeout 10m;
    }
   

Reload Nginx web server

$ sudo service nginx reload

Testing

$ curl -I http://r00t4bl3.com
HTTP/1.1 301 Moved Permanently
Server: nginx/1.10.2
Date: Thu, 02 Nov 2017 18:13:42 GMT
Content-Type: text/html
Content-Length: 185
Connection: keep-alive
Location: https://www.r00t4bl3.com/

If the response code is 301 and the location is https, then we're set.
