Description

Esta nova versão contém as configuracões atuais da spgrid depois do upgrade.

Editamos o /etc/named.conf

//
// named.conf for Red Hat caching-nameserver

options {
        directory "/var/named";

        /*
         * If there is a firewall between you and nameservers you want
         * to talk to, you might need to uncomment the query-source
         * directive below.  Previous versions of BIND always asked
         * questions using port 53, but BIND 8.1 uses an unprivileged
         * port by default.

As configuracoes para o dominio sprace.org.br ficam em /var/named/chroot/var/named, fazendo um cp -p do named.local para estes arquivos e editando:

[root@spgrid named]# more sprace.org.br.zone
$TTL    86400
;Nome do servidor e e-mail do administrador
@       IN      SOA    osg-ce.sprace.org.br. root.osg-ce.sprace.org.br  (
                                      1997022700 ; Serial

e o reverso

[root@spgrid named]# more 80.136.200.in-addr.arpa.zone
$TTL    86400
@       IN      SOA     osg-ce.sprace.org.br. root.osg-ce.sprace.org.br.   (

3       IN      PTR     access.sprace.org.br.
4       IN      PTR   osg-ce.sprace.org.br.

No caso do dominio grid:

[root@spgrid named]# vim grid.zone
$TTL    86400
@       IN      SOA     spg00.grid. root.spg00.grid.  (
                                      1 ; Serial
                                      8H      ; Refresh
                                      2H      ; Retry
                                      1W    ; Expire
                                      1D )    ; Minimum
;Servidor de nomes
@          IN      NS      spg00.grid.
;Servidor de e-mail
@          IN      MX  0  spg00.grid.
;Especificando enderecos
@          IN      A    192.168.1.150 ;(ip do servidor)
spg00      IN      A     192.168.1.150
;Adicionando apelidos
mail       IN     CNAME  spg00

e o reverso é feito em

[root@spgrid named]# more 1.168.192.in-addr.arpa.zone
$TTL    86400
@       IN      SOA     spg00.grid. root.spg00.grid.  (
                                      1 ; Serial
                                      8H      ; Refresh
                                      2H      ; Retry
                                      1W    ; Expire
                                      1D )    ; Minimum
;Especificando o servidor de nomes

;Adicionando endereços reversos
