VMware安装Redhat6.4系统安装DNS服务启动服务器报错
mount /dev/cdrom /mnt/cdrom
yum install -y bind
vi /etc/named.conf

options最终保留与注释情况如下：

options {

listen-on port 53 { 127.0.0.1; };

listen-on-v6 port 53 { ::1; };
directory     "/var/named";
dump-file     "/var/named/data/cache_dump.db";
    statistics-file "/var/named/data/named_stats.txt";
    memstatistics-file "/var/named/data/named_mem_stats.txt";

allow-query { localhost; };

recursion yes;

};

include 保持不变
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";

测试配置是否正确
named-checkconf /etc/named.conf
测试成功的

配置named.rfc1912.zones
vi /etc/named.rfc1912.zones
增加以下这段
zone "example.com" IN {
type master;
file "example.com.zone";
allow-update { none; };

先创建一个example.com.zone文件
配置example.com.zone
vi /var/named/example.com.zone

$TTL 1D
@ IN SOA ns root.ns.example.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS ns
A 192.168.3.10
ns A 192.168.3.10
prod-scan A 192.168.3.30
prod-scan A 192.168.3.31
prod-scan A 192.168.3.32

检查测试配置是否正确
named-checkzone "example.com" /var/named/example.com.zone
也是成功的

启动DNS服务
service named restart

报错
[root@rac01 ~]# service named restart

烦请各位帮我看看，哪里出现了问题，为什么DNS会报错，谢谢
