我有这样设置绑定：
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
options {
listen-on port 53 { any; };
# listen-on-v6 port 53 { ::1; };
directory "/var/named";
forwarders { 10.90.0.135; 10.90.0.174; };
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 { any; };
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;
/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
zone "appletop.local" IN {
type master;
file "appletop.local";
allow-update { none; };
};
但它没有前进？
如果我只是将DNS服务器地址放在另一台机器上的resolv.conf中,我会得到正确的查找,因此DNS服务器必须能够为我解析,但如果我再将其他机器指向此处,则无法解析名称.
怎么了？
在MadHatter建议更改后：
现在它开始但挂在挖掘痕迹上并且不转发 – 为什么我看不到下面的转发器地址？
[root@ns1 ~]# ping www.yahoo.com ^C [root@ns1 ~]# cd /etc/ [root@ns1 etc]# cp named.conf named.conf.last [root@ns1 etc]# vi named.conf [root@ns1 etc]# /etc/init.d/named reload Reloading named-sdb: [ OK ] [root@ns1 etc]# service named stop Stopping named: .

并挖掘跟踪：
[root@ns1 etc]# dig +trace www.yahoo.com ; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.17.rc1.0.2.el6_4.6 <<>> +trace www.yahoo.com ;; global options: +cmd . 518400 IN NS E.ROOT-SERVERS.NET. . 518400 IN NS M.ROOT-SERVERS.NET. . 518400 IN NS I.ROOT-SERVERS.NET. . 518400 IN NS F.ROOT-SERVERS.NET. . 518400 IN NS G.ROOT-SERVERS.NET. . 518400 IN NS K.ROOT-SERVERS.NET. . 518400 IN NS B.ROOT-SERVERS.NET. . 518400 IN NS A.ROOT-SERVERS.NET. . 518400 IN NS C.ROOT-SERVERS.NET. . 518400 IN NS L.ROOT-SERVERS.NET. . 518400 IN NS J.ROOT-SERVERS.NET. . 518400 IN NS H.ROOT-SERVERS.NET. . 518400 IN NS D.ROOT-SERVERS.NET.
我的整个文件现在看起来像这样 – 什么不对？
