i am trying to configure my new server without cpanel

i've installed php/mysql/apache

And it's now working fine

if you visit the server ip

http://46.166.129.101/

you'll see the welcome page

i've configured my dns too

my nameserverips file

[root@server]# cat /etc/nameserverips
46.166.129.101=ns1.isellsoftwares.com
46.166.129.101=ns2.isellsoftwares.com

if you visit this link http://ns1.isellsoftwares.com

you'll see the welcome page too!!

but if you visit isellsoftwares.com

you'll see ( 'Firefox can't find the server at www.isellsoftwares.com.' )

Now my question is: How to create an account for this domain on the server??

i've tryied to add virtualHost tag in apache

<VirtualHost *:80>
    ServerAdmin [email protected]
    ServerAlias www.isellsoftwares.com
    DocumentRoot /var/www/html/issoft
    ServerName isellsoftwares.com
    ErrorLog logs/dummy-host.example.com-error_log
    CustomLog logs/dummy-host.example.com-access_log common
</VirtualHost>

it still not working ...

i've added named file for this domain (( isellsoftwares.com.db ))

; Zone file for isellsoftwares.com
$TTL 14400
isellsoftwares.com.     86400   IN      SOA     ns1.isellsoftwares.com. elsolgan.yahoo.com.     (
