NGINX HTTP to HTTPS and Non-WWW to WWW Redirect Configuration

config

# NGINX Server Block for:
#	Redirect non-www base domain (domain.com) to www (www.domain.com)
#	Redirect HTTP to HTTPS SSL (HTTP2)
#	Supports multiple domains and subdomains
#	Created by George Liu (www.georgeliu.me / Github:tgmgroup)

# STEP 1 - Base HTTPS Block

server {
	#Listen only on HTTPS, use STEP 3 to redirect from HTTP
	listen 443 ssl http2;
	listen [::]:443 ssl http2;

	# Put Includes Here

	# Change .domain1.com and .domain2.com to your own domain
	# The .domain1.com wildcard format (DOT domain) catches all domains and subdomains of domain1.com
	server_name .domain1.com .domain2.com;

	# Put Server Configs Here

	# Put Other Configs Here
	}


# STEP 2 -  Redirect base (non-www URL) to HTTPS www

server {
	listen 80;
	listen [::]:80;
	listen 443 ssl http2;
	listen [::]:443 ssl http2;

	# Catch only www subdomains on HTTP and HTTPS
	server_name domain1.com domain2.com;
	# Permanent redirect to HTTPS and www
	return 301 https://www.$host$request_uri;

	# Use the following if redirecting www to non-www URLs
	#        server_name www.domain1.com www.domain2.com;
	#        return 301 https://$host$request_uri;

	# If using both HTTPS and HTTP (only www redirect), edit STEP 1 to include 
	#        listen 80;
	#        listen [::]:80;
	# and remove STEP 3
	# and change the return 301 line to use "$scheme://" instead of "https://"
}


# STEP 3 -  Redirect all non- base-non-www HTTP to HTTPS

server {
	listen 80;
	listen [::]:80;

	# Catch all base and subdomains on HTTP, including redirects from STEP 2
	server_name .domain1.com .domain2.com;

	# If user prefers, use "www.domain1.com *.domain1.com" combination instead of
	# ".domain1.com" wildcard to avoid NGINX warnings

	return 301 https://$host$request_uri;
