RH9下DNS配置的详细过程,错在哪里!!!知道的兄弟不要闪啊!!

xie_rongc · 发表于 2004-4-9 13:23:28

为学习RH9下的服务器配置，有如下环境：二台计算机与一个HUB，其中一个计算机安装RH9，另一个为WINDOWS 98

要求：安装RH9的计算机要发挥DNS服务器和WWW服务器的功能。
   安装WINDOWS 98的计算机仅作为测试使用。

安装：
首先在机器上安装RH9，未设置网卡，将防火墙设置为无，安装DNS服务器软件包（2个）和WWW服务器软件包。

RH9主机名为：red.rong.com IP地址为192.168.0.10

配置：
1.设置主机名
#hostname red.rong.com

编辑/etc/sysconfig/network文件,修改后为
NETWORKING=yes
HOSTNAME=red.rong.com

编辑/etc/hosts文件,修改后为

127.0.0.1  localhost.localdomain  localhost
192.168.0.10 red.rong.com       red

2.设置IP

利用GNOME下系统设置的网络，输入IP地址192.168.0.10 子网掩码255.255.255.0

3.编辑/etc/named.conf

在默认文件的最后填加如下内容

zone "rong.com" {
type master;
file "rong.com.hosts";
};

zone "0.168.192.in-addr.arpa" {
type master;
file "192.168.0.rev";
};

4.编辑/var/named/rong.com.hosts
$ttl 1D
@  IN SOA red.rong.com. root.red.rong.com.
(
1053891152
3H
15M
1W
1D  )
IN NS red.rong.com.
red IN A  192.168.0.10
www IN CNAME red.rong.com.

5.编辑/var/named/192.168.0.rev
$ttl 1D
@ IN SOA  red.rong.com.  root.red.rong.com.
(
      1053892104
      3H
      15M
      1W
      1D )
IN NS red.rong.com.
10  IN PTR red.rong.com.

6.编辑/etc/resolv.conf，文件修改为
nameserver 192.168.0.10

7.启动DNS服务
#service named start

8.测试DNS
#host red.rong.com
Host red.rong.com net found:2(SERVFAIL)

我已经想破头了,还是不知道错在哪里!!!郁闷啊,郁闷!!!

出现这个错误提示：
[root@ent3 named]# service named restart
Stopping named: rndc: connect failed: connection refused
[FAILED]
Starting named: [ OK ]
还有就是53端口没打开，不知道是怎么回事，请大家帮忙！

看你的配置好像是对的，是不是重新启动一下试试(LINUX一般不用重启的)。有没有配置防火墙，比如安装里默认的防火墙规则，关掉iptables试试。

7dehao · 发表于 2004-4-9 16:03:32

我在测试中关掉了防火墙，但发现就是53端扣是没有打开，不知道怎么打开，用service named restart也不能打开。
用host -T ent3.test.com测试，显示不能和主机的IP的53端口连接。

真奇怪啊!!

7dehao兄弟
你问的问题，我在哪里见到过restart的问题，是RH9的问题，我记得如果把内核升级一下可以解决。

把/var/log/messages中的信息也公布出来，请大家帮忙！

service named stop
service named reload
service named restart

我自己的问题已经解决，原来是我在改写/etc/named.conf文件时把最后一行中的include删掉了第一个i，所以出了问题，在service named named的时候报错显示不能识别"nclude"，开始看不懂，现在改过来就好了。

我把我的配置文件贴上来，看看和你的有什么不一样的地方：
