How subdomain on named chrooted ?

Helo everybody,

I need help to set a subdomain on named chrooted . First ,think is necessary, to insert a new zone in var/named/chroot/etc/named.conf:
zone "subdomain.domain.ro" {
type master;
file "subdomain.domain.ro";
};
or is not nessary ?
Than in /var/named/chroot/var/named/ insert a new file named subdomain.domain.ro with this script :

subdomain.domain.ro. IN SOA ns1.subdomain.domain.ro. root.localhost. (
2007121201 ; Serial
10800 ; Refresh
3600 ; Retry
604800 ; Expire
38400 ; Minimum TTL
)

; servere DNS
IN NS ns1.subdomain.domain.ro.


; MX Records
IN MX 10 mail.subdomain.domain.ro.

subdomain.domain.ro. A 77.97.93.210

; Hosts
ns1 IN A 77.97.93.210
mail IN A 77.97.93.210
www IN A 77.97.93.210
IN A 77.97.93.210
Finaly in /etc/httpd/conf/httpd.conf a new virtualhost

Is this correct?

 

You must create the subdomain record in the domain.ro zone.
