How to redirect blog.domain.com to domain.com/blog

Hello all,

I’m facing serious problems to figure out how to redirect a subdomain to my primary domain. Specifically I want al requests under blog.mydomain.com to redirect to mydomain.com/blog On my Ubuntu 14.04 I have created a Vhost and inside the document root I have added a .htaccess file with the following directive:

# Various rewrite rules.
<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_HOST} ^blog.mydomain.com [NC]
  RewriteRule ^(.*)$ http://mydomain.com/blog/$1 [R=301,L]
</IfModule>

I also tried the above directive directly in apache2.conf file but with no result. When I try to go to the blog.mydomain.com url I get the Apache2 Ubuntu Default Page

In my DNS records I have A — mydomain — droplet IP A — @ — droplet IP A — * — droplet IP CNAME — www — mydomain.

I Probably don’t need the * A record but after so many suggestions and attempts I’ve lost track of what should and shouldn’t be there.

I would like to set it up directly on Apache instead of using .htaccess but any suggestion/help would be highly appreciated.
