How to redirect Nginx non-www to www domain over SSL?

First of all your need SSL certificate for both domains test.in and www.test.in.

Step 1 – Redirect https://test.in to https://www.test.in

Edit your nginx.conf or domain level conf file using a text editor such as vim command:

$ sudo vi /etc/nginx/sites-enabled/theos.in.conf

Append the following config:

 ### redirect HTTPS n
server {
    listen 443 ssl;
    server_name theos.in;
    ssl_certificate /etc/nginx/ssl/letsencrypt/non-www.test.in/test.in.cer;
    ssl_certificate_key /etc/nginx/ssl/letsencrypt/non-www.test.in/test.in.key;
    return 301 https://www.test.in$request_uri;
}

Step 2 – Nginx configuration for https://www.test.in

Here is my sample config:

server {
    access_log  /var/log/nginx/www.test.in_access.log;
    error_log  /var/log/nginx/www.test.in_error.log;
    listen 443 ssl http2;
    server_name www.test.in;
    # adjust as per your needs #
    # certs sent to the client in SERVER HELLO are concatenated in ssl_certificate #
    ssl_certificate /etc/nginx/ssl/letsencrypt/www.test.in/www.theos.in.cer;
    ssl_certificate_key /etc/nginx/ssl/letsencrypt/www.test.in/www.test.in.key;
    ssl_session_timeout 1d;
    ssl_session_cache shared:SSL:50m;
    ssl_session_tickets off;
    ssl_dhparam /etc/nginx/ssl/letsencrypt/theos.in/dhparams.pem;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers 'ECDHE-ECDSA-CHACHA20-POLY1305:ECDHE-RSA-CHACHA20-POLY1305:ECDHE-ECDSA-AES128-
GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-

SHA256:AES128-SHA:AES256-SHA:DES-CBC3-SHA:!DSS';
    ssl_prefer_server_ciphers on;
 
    add_header Strict-Transport-Security "max-age=15768000; includeSubDomains; preload" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Xss-Protection "1";
 
    # OCSP Stapling 
    # fetch OCSP records from URL in ssl_certificate and cache them
    ssl_stapling on;
    ssl_stapling_verify on;
    #resolver <IP DNS resolver>;
 
    ssl_buffer_size 8k;
    ## rest of your config below such as php-cgi, documentroot and more ##
}

Step 3 – Redirect all HTTP traffic to HTTPS

Of course, all HTTP traffic must be sent to HTTPS server so that Strict-Transport-Security works correctly. Append following in your config file too:

# Redirect www.test.in:80 to https://www.test.in:443
server {
    listen      80;
    access_log  off;
    error_log   off;
    server_name www.test.in;
    return         301 https://$server_name$request_uri;
}
# # Redirect http://test.in:80 to https://test.in:443
server {
    listen      80;
    access_log  off;
    error_log   off;
    server_name test.in;
    return         301 https://$server_name$request_uri;
}

Make sure you reload or restart the nginx server:

$ sudo systemctl reload nginx

$ sudo service nginx reload

Make sure you reload or restart the nginx server:

$ sudo systemctl reload nginx

$ sudo service nginx reload
