How to make a redirect without www for a subdomain?

Question

htaccess

Good afternoon.
Faced a problem. There is a subdomain "sub.site.com" and you need to redirect from "www.sub.site.com" to "sub.site.com".
Googled and the solution suggested didn't work for me. If someone has solved this problem, please share your answer.

Answer 1

In .htaccess

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

Don't forget to enable mod_rewrite

a2enmod rewrite
service apache2 restart
