问题
My homepage is located at www.nazgulled.net and I bought a new domain which is www.ricardoamaral.net. Both these domains point to the same exact server.
I'm having two problems with the redirection, my current code is this:
RewriteCond %{HTTP_HOST} ^(www\.)?nazgulled\.net [NC]
RewriteRule ^(.*)$ http://www.ricardoamaral.net/$1 [L]
For now I'm just testing but the idea is to replace [L] with [L,R=301] when I'm ready to move the whole thing, just so you know.
Anyway...
1) This is not working, when I try it, I can't access "nazgulled.net", it gives me a "server internal error" and I don't understand why... I don't understand why because if replace "ricardoamaral.net" by "google.com", the redirect works just fine :/
2) I have a few subdomains and I would like to redirect everything in those too. My first choice is to add different rewrite conditions/rules for each of the subdomains but that takes a lot of manual code and if the user types some subdomain that doesn't exist, they don't be redirect it and I also want that.

For 1, you can use something like this instead:
<VirtualHost *:80>
ServerAdmin webmaster@nazgulled.net
ServerName nazgulled.net
ServerAlias www.nazgulled.net
Redirect permanent / http://www.ricardoamaral.net/
</VirtualHost>
I use a similar configuration and it works perfectly, keeping query parameters, paths, etc.
Regarding your own rewrite rule, I want to note that you may lose your query params if you don't include QSA.
To diagnose internal server errors, just have a look at the log file provided by your ErrorLog directive within your vhost, or a global one, depending on your configuration. It should give you the exact reason for the error.

I think for your situation creating separate vhosts would be the ideal fit. What I do often is place domains that are being redirected on the same server but in a different folder to keep the www folder clean, for instance. My main site would be here:
/var/www/example.com/public
For all my redirects I would place them like so:
/var/www/redirects/example-2.com/public
Within each public folder of the redirected sites you would add this line to your .htaccess file
RedirectMatch permanent /.* http://example.com/

This is best solutions. Create a notepad file and save it as .htaccess if you do not already have an existing one. Update the .htaccess file with the following code and save
Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://new-domain.com/$1 [R=301,L]
