Dear All

I need to change the database directory for my zone files from default /var/named .For example forward lookup files should be placed in some other directory like /var/named/fwd and reverse lookup files in some other directory /var/named/rev ,and few critical domains file in seperate directory like /var/named/critical .

Can some one guide me how to do that.

Thanks in advance

Hi,

Yes, u can change your default location. Change the file derictive option in named.conf and specify your desired location.

Hope it wil do what you want.

Leave the directory option as is in your named.conf, e.g

Code:

 directory "/var/named";

and then in your zones definition do something like:

Code:

zone "A" {
        type master;
        file "fwd/A.zone";
};

zone "A.rev" {
        type master;
        file "rev/A.zone";
};

zone "criticalA" {
        type master;
        file "critical/criticalA";

Dear Friends

This time i am trying to seperate all the zone definations from named.conf.For example all the forward lookup zones definations should be in the
/etc/zonedef/zones.def

All the reverse lookup defination in
/etc/zonedef/rev.def
All the customer related zonedef in
/etc/zonedef/customer.def

I am trying to do this by placing following lines in named.conf

include "/etc/zonedef/zones.def";
include "/etc/zonedef/rev.def";
include "/etc/zonedef/customer.def";

But when i start the service i get following error

[root@localhost etc]# service named start
Starting named: /etc/named.conf:26: open: /etc/zonedef/zones.def: file not found

Nov 26 22:02:18.803 exiting (due to early fatal error)
Error in configuration file /etc/named.conf : [FAILED]

Although the file zones.def is there at the specified location.I even change the owner ship of the file to named:named ,even change the permision to 777 but no use.
As soon as i comment out the last three lines of

//include "/etc/zonedef/zones.def";
//include "/etc/zonedef/rev.def";
//include "/etc/zonedef/customer.def";

It start without any error.

Can some body help me in this

Do you understand what chroot does? It changes where / is for that process. If named is chroot'd into /var/named, it can't get to /etc. /var/named/etc is the new /etc. You need to put your include files in /var/named/etc.
