You need to install a httpd, like apache or lighttpd, otherwise you won't be able to see anything using your browser.
It's also possible to install LAMP which includes Apache, PHP, mySQL and Mail.
Also I forgot to mention for your name server go to your LXAdmin panel.
Than DNS Templates, on the middle top you will see " Add DNS Templates "
Add your name server which should be NS1.YOURSITE.COM & NS2.YOURSITE.COM from there with your IP. After you did that save.
Than go to your domain provider and for the name servers add the IP and NS1.YOURSITE.COM & NS2.YOURSITE.COM
Tell me how it goes.
