Start bind trong CentOS bị lỗi!

Mình start bind trong CentOS bị lỗi, không biết là lỗi gì?

Code:

[root@ns ~]#service named start
Starting named:                                            [FAILED]

Đây là named.conf của mình, chủ yếu là 2 zone cuối cùng:

Code:

options{
        directory "/var/named";
};


zone "." IN {
        type hint;
        file "named.ca";
};

zone "localdomain" IN {
        type master;
        file "localdomain.zone";
        allow-update { none; };
};

zone "localhost" IN {
        type master;
        file "localhost.zone";
        allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
        type master;
        file "named.local";
        allow-update { none; };
};

zone "0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
        type master;
        file "named.ip6.local";
        allow-update { none; };
};

zone "255.in-addr.arpa" IN {
        type master;
        file "named.broadcast";
        allow-update { none; };
};

zone "0.in-addr.arpa" IN {
        type master;
        file "named.zero";
        allow-update { none; };
};

zone "centos.net" IN {
        type master;
        file "centos.net.db";
        allow-update {none;};
};

zone "1.168.192.in-addr.arpa" IN {
        type master;
        file "1.168.192.db";
        allow-update {none;};
};

Đây là zone centos.net.db:

Code:

$TTL 86400
@       IN      SOA     ns.centos.net.  root.centos.net. (
                201005201       ;serial
                3600            ;refresh
                1800            ;retry
                604800          ;expire
                86400           ;minimum
)

                IN      NS      ns.centos.net.
                IN      A       192.168.1.153

ns              IN      A       192.168.1.153

Đây là zone 1.168.192.db:

Code:

$TTL 86400
@       IN      SOA     ns.centos.net.  root.centos.net. (
                201005201       ;serial
                3600            ;refresh
                1800            ;retry
                604800          ;expire
                86400           ;minimum
)

        IN      NS      ns.centos.net.

153     IN      PTR     ns.centos.net.

Đây là log messages:
