I have a server. I installed and configured Virtualmin/Webmin on it. Also I added three domains and configured almost 100% correct all DNS records.
My big question is how I restrict accessing website through server IP. Or how to redirect the IP to a specific location from my server to load specific files?
You should use virtualhosts for that. Something along lines
# Ensure that Apache listens on port 80
Listen 80
# Listen for virtual host requests on all IP addresses
NameVirtualHost *:80
<VirtualHost *:80>
DocumentRoot /www/ip_address_root
ServerName 123.123.123.123
# Other directives here
</VirtualHost>
<VirtualHost *:80>
DocumentRoot /www/example2
ServerName www.example.org
# Other directives here
</VirtualHost>
(Example copied from here)
Alternatively, mod_rewrite helps with this. Something like
RewriteCond %{REMOTE_HOST} ^123\.123\.123\.123$
RewriteRule .* http://www.example.org/you_are_using_ip_address [R=301]
Try to map the ip to localhost in /etc/hosts
