NGINX Configuration File Using Let's Encrypt SSL HTTPS Certificate

This is somewhat my default configuration file for all my websites I run.

This might be handy for some folks.

# Advanced config for NGINX
	server_tokens off;
	add_header X-XSS-Protection "1; mode=block";
	add_header X-Content-Type-Options nosniff;

# Redirect all HTTP traffic to HTTPS
server {
  listen 80;
  server_name www.domain.com domain.com;
  return 301 https://$host$request_uri;
}

# SSL configuration
server {
  listen 443 ssl default deferred;
  server_name www.domain.com domain.com;
  ssl_certificate      /etc/letsencrypt/live/www.domain.com/fullchain.pem;
  ssl_certificate_key  /etc/letsencrypt/live/www.domain.com/privkey.pem;

# Improve HTTPS performance with session resumption
  ssl_session_cache shared:SSL:10m;
  ssl_session_timeout 5m;

# Enable server-side protection against BEAST attacks
  ssl_prefer_server_ciphers on;
  ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5;

# Disable SSLv3
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

# Enable HSTS (https://developer.mozilla.org/en-US/docs/Security/HTTP_Strict_Transport_Security)
  add_header Strict-Transport-Security "max-age=63072000; includeSubdomains";
