之所以要写一个RHEL5.3 DNS配置，是因为RHEL5.3和RHEL4.6的配置有很大的区别。
1.设置IP地址
# ifconfig eth0 192.168.1.5/24
2.设置DNS服务器地址
# vim /etc/resolv.conf
nameserver 192.168.1.5
:wq
3.关闭路由功能
# service iptables stop
4.挂载光盘
# mount /dev/cdrom /media //RHEL5.3里/media目录下没有cdrom目录
5.安装bind-9* caching-nameserver* bind-chroot*三个软件包
# cd /media/Server //光盘挂载后，在/media目录下会多出一个Server目录
# rpm -ivh bind-9*
# rpm -ivh caching-nameserver*
# rpm -ivh bind-chroot*
6.RHEL5.3里没有named.conf文件，所以这里要把named.caching-nameserver.conf复制为
1.设置IP地址
# ifconfig eth0 192.168.1.5/24
2.设置DNS服务器地址
# vim /etc/resolv.conf
nameserver 192.168.1.5
:wq
3.关闭路由功能
# service iptables stop
4.挂载光盘
# mount /dev/cdrom /media //RHEL5.3里/media目录下没有cdrom目录
5.安装bind-9* caching-nameserver* bind-chroot*三个软件包
# cd /media/Server //光盘挂载后，在/media目录下会多出一个Server目录
# rpm -ivh bind-9*
# rpm -ivh caching-nameserver*
# rpm -ivh bind-chroot*
6.RHEL5.3里没有named.conf文件，所以这里要把named.caching-nameserver.conf复制为
named.conf
# cd /etc //一定要进入/etc目录下复制文件才有效果
# cp -a named.caching-nameserver.conf named.conf
7.修改named.conf配置文件
# vim /etc/named.conf
options {
listen-on port 53 { any; 127.0.0.1; }; //这里添加any;允许所有
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";
query-source port 53; //这里删除注释
allow-query { any; localhost; }; //这里添加any;允许所有
};
view localhost_resolver {
match-clients { any; localhost; }; //这里添加any;允许所有
match-destinations { localhost};
recursion yes;
include "/etc/named.rfc1912.zones";
};
:wq
后面的和RHEL4.6差不多
8.修改named.rfc1912.zones配置文件
# vim /etc/named.rfc1912.zones
zone "xt.com" IN {
type master;
file "xt.com.zone";
allow-update { none; };
};
zone "1.168.192.in-addr.arpa" IN {
type master;
file "192.168.1.local";
allow-update { none; };
};
:wq
9.将localhost.zone和named.local复制为xt.com.zone和192.168.1.local
# cd /var/named/chroot/var/named
# cp -a localhost.zone xt.com.zone
# cp -a named.local 192.168.1.local
10.修改xt.com.zone配置文件
# vim xt.com.zone
$TTL 86400
@ IN SOA @ root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS @
IN A 192.168.1.5
www IN A 192.168.1.5
mail IN A 192.168.1.5
IN MX 5 mail.xt.com.
:wq
11.修改192.168.1.local配置文件
# vim 192.168.1.local
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
5 IN PTR www.xt.com.
:wq
11.启动named服务
# service named start
12.测试正向和反向解析
# nslookup www.xt.com
# nslookup 192.168.1.5
# cd /etc //一定要进入/etc目录下复制文件才有效果
# cp -a named.caching-nameserver.conf named.conf
7.修改named.conf配置文件
# vim /etc/named.conf
options {
listen-on port 53 { any; 127.0.0.1; }; //这里添加any;允许所有
listen-on-v6 port 53 { ::1; };
directory "/var/named";
