Nginx redirect http to https and non www to www

Redirect HTTP to HTTPS (http://www.example.com to https://example.com)

server {
	server_name www.example.com;
	listen 80 ;
	access_log /var/log/nginx/access.log vhost;
	return 301 https://$host$request_uri;
}

Redirect non-WWW to WWW (https://example.com to https://www.example.com)

SSL certificate configuration must be defined

• ssl_certificate /etc/nginx/certs/example.com.crt;
• ssl_certificate_key /etc/nginx/certs/example.com.key;
• ssl_dhparam /etc/nginx/certs/example.com.dhparam.pem;

server {
	server_name example.com;
	listen 443 ssl http2 ;
	ssl_certificate /etc/nginx/certs/example.com.crt;
	ssl_certificate_key /etc/nginx/certs/example.com.key;
	ssl_dhparam /etc/nginx/certs/example.com.dhparam.pem;
	return 301 $scheme://www.example.com$request_uri;
}

Redirect http://example.com to https://www.example.com

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

We could have merged this configuration with the first one :

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

Redirect IP address to domain name

Of course your SSL certificate must be valid for the IP address

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

server {
  server_name xxx.xxx.xxx.xxx;
  listen 443 ssl http2 ;
  ssl_certificate /etc/nginx/certs/example.com.crt;
  ssl_certificate_key /etc/nginx/certs/example.com.key;
  ssl_dhparam /etc/nginx/certs/example.com.dhparam.pem;
  return 301 https://example.com$request_uri;
}

Main config catching https://www.example.com used as a reverse proxy here

server {
	server_name www.example.com;
	listen 443 ssl http2 ;
	access_log /var/log/nginx/access.log vhost;
