Redirect all subdomains and www to non-www

Question

I would like to redirect all subdomains and www to my main “non-www” domain.

So:

www.example.com AND sub.example.com AND www.sub.example.com

Should all become:

example.com

How could I do this using mod_rewrite?

Thanks

As already mentioned, I need to redirect every subdomain as well. — Balázs Vincze, Oct 02 '17 at 01:44
at the bottom of the page there is an answer by @Gregor Macgregor which works with subdomain — Aref Ben Lazrek, Oct 02 '17 at 02:02

This suggests the following redirects www.example.com to example.com:

RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]

As such, you could use the following to redirects anything that ends with .example.com to example.com:

RewriteCond %{HTTP_HOST} \.example\.com$ [NC]
RewriteRule ^(.*)$ http://example.com/$1 [R=301,L]

The following is a more generic solution (but it doesn't work for domains that are part of multi-level TLDs, such as www.theregister.co.uk):

RewriteCond %{HTTP_HOST} \.([^.]+\.[^.]+)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

Thanks so much, just what I needed! Could you maybe tell me, how to redirect http request to https for the main domain? — Balázs Vincze, Oct 02 '17 at 13:01
