Question

linux中配置dns转发器配置错误啊

我在DNS转发文件中的配置如下：
[root@server etc]# vi named.conf
forwarders { 61.134.1.4; 218.30.19.50; };
重启服务就会出现。[root@server etc]# service named restart
Stopping named: [FAILED]
Starting named:
Error in named configuration:
/etc/named.conf:1: unknown option 'forwarders'
[FAILED]帮忙找下原因啊。或者+584471863帮忙解决下

最主要的就是修改配置文件即可：

vi /etc/named.caching-nameserver.conf

options {
listen-on port 53 { 192.168.1.128; };
// 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";

// Those options should be used carefully because they disable port
// randomization
query-source port 53;
// query-source-v6 port 53;
forward first;
forwarders { 61.147.37.1; };
allow-query { any; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
// match-clients { localhost; };
// match-destinations { localhost; };
recursion yes;
include "/etc/named.rfc1912.zones";
};

辅助DNS（Slave）的详细配置(2009-04-13 00:00:00)

实验环境：master-dns的ip为192.168.1.128

slave-dns的ip为192.168.1.169

步骤1：

在master加入配置文件为：

options {
listen-on port 53 { 192.168.1.128; };
// 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";

// Those options should be used carefully because they disable port
// randomization
query-source port 53;
// query-source-v6 port 53;

allow-query { any; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
// match-clients { localhost; };
// match-destinations { localhost; };
recursion yes;
include "/etc/named.rfc1912.zones";
};
再加入下面配置文件，

vi /etc/named.rfc1912.zones

zone "caixia.net" IN {
type master;
file "caixia.zone";
# allow-update { none; };
};

zone "1.168.192.in-addr.arpa" IN {
type master;
file "caixia.local";
# allow-update { none; };
};
启动服务:service named restart

步骤2：

修改Slave配置文件：

vi /etc/named.caching-nameserver.conf

options {
listen-on port 53 { 192.168.1.169; };
// 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";

// Those options should be used carefully because they disable port
// randomization
query-source port 53;
// query-source-v6 port 53;

allow-query { any; };
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
view localhost_resolver {
// match-clients { localhost; };
// match-destinations { localhost; };
recursion yes;
include "/etc/named.rfc1912.zones";
};

vi /etc/named.rfc1912.zones

zone "caixia.net" IN {
type slave;
masters { 192.168.1.128; };
file "slaves/caixia.zone";
};

zone "1.168.192.in-addr.arpa" IN {
type slave;
masters { 192.168.1.128; };
file "slaves/caixia.local";

};

步骤3：

vi /etc/resolv.conf

nameserver 192.168.1.169

DNS的ip指向自己，最好启动服务，service named start

用host或者nslookup进行验证。

Answer 2

没有添加监听端口，还有，没有创建正向反向区域。

Answer 3

我是这样写的，没得问题。
forwarders {
61.139.2.69;
202.106.0.22;
};
