NGINX: redirect non-www https to https://www

问题:

I followed this answer https://stackoverflow.com/a/28068250/3108268 but it redirects only from http to https and non www to www, but if I go to my website at https://example.com I get 'your connection is insecure'.

How do I redirect it to https://www?

server{
  listen 443 ssl;
  server_name www.mydomain.com;
  root /www/mydomain.com/;

  ssl    on;
  ssl_certificate /ssl/domain.crt;
  ssl_certificate /ssl/domain.key;
  .
  . 
  .
}

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

server{
  listen 443;
  server_name mydomain.com;
  return 301 https://www.$server_name$request_uri;
} 

回答1:

the third server is missing SSL certificates which is why the browser is saying the connection is insecure.

replace your last two servers with:

# redirect www.mydomain.com to https
server {
  listen 80;
  server_name www.mydomain.com;
  return 301 https://$server_name$request_uri;
}

# redirect mydomain.com to https
server{
  listen 80;
  server_name mydomain.com;
  return 301 https://www.$server_name$request_uri;
}

A good way to get the correct configuration is using new blocks for each redirect, one from http to https and one to non-www to www.

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

server {
    listen 443 ssl;
    ssl_certificate     /path/to/certificate.crt;
    ssl_certificate_key /path/to/private/key.pem;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    server_name www.example.com;
    return 301 https://example.com$request_uri;
}

server {
    listen 443 ssl;
    ssl_certificate     /path/to/certificate.crt;
    ssl_certificate_key /path/to/private/key.pem;
    ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
    server_name example.com;

    # do the proper handling of the request
}
