How to redirect all HTTP requests to HTTPS AND redirect all nonexistent subdomains to one specific domain

  • 772

I already have a working configuration to redirect all non-existent subdomains to a specific domain. Now I want to add a configuration that redirects all HTTP requests to HTTPS on the same domain.

This config file does the subdomain redirects:

# redirect any non-existent subdomain (blah.domain.de -> domain.de)
server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name _;
    return 301 https://domain.de$request_uri;
}

And this is the config I try to use for HTTP->HTTPS:

# redirect any HTTP request to its HTTPS address (http://domain.de/blub -> https://domain.de/blub)
server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name domain.de mail.domain.de admin.domain.de;
    return 301 https://$server_name$request_uri;
}

But this doesn't work because the default_server is defined twice. How can combine these two functions?

Do I really have to add the second config to every single subdomain config?

nginx

  1. You need to remove default_server from the latter configuration and add every domain name to the server_name part.

    Then you need to use return 301 https://$host$request_uri; for the redirect statement.

  2. Nginx does not support nested if statements (it also doesn't support complex conditions).

    I got it working in another way. I added it to every subdomains config via a SSL snippet. Every subdomain config includes the same SSL config. So I added to this config a http check:

    if ($scheme = http ){
    rewrite ^ https://$server_name$request_uri permanent;
}
# ... followed by ssl config

    And this is included in every subdomain server block config:

    include snippets/ssl.conf;

    It does what I want. Maybe there is another way without including it to every subdomain.
