Centos Bind配置完整版
首先要成功安装Centos操作系统,最新版本是Centos 6.4版本,最小化安装。
[root@localhost named]# ifconfig -a
inet addr:192.168.1.251 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr: f180::225:5cff:fe01:691c/64 Scope:Link

RX bytes:1944 (1.8 KiB) TX bytes:1944 (1.8 KiB)
可以看到本地网卡是eth1和lookback,编辑eth1网卡。
[root@localhost named]# vi /etc/sysconfig/network-scripts/ifcfg-eth1
BOOTPROTO=static #静态IP
IPADDR=192.168.1.251 #静态ip地址
NETMASK=255.255.255.0 #子网掩码
GATEWAY=192.168.1.1 #网关
如果配置正确的情况是,现在是可以上网的,ping 一个ip地址测试下。但是无法进行域名解析,因此需要设置本机的dns。
[root@localhost named]# vi /etc/resolv.conf
加入内容:
nameserver 8.8.4.4 #备用DNS服务器
此时,网络已经配置完毕,让我们开启bind配置之旅吧!
[root@localhost ~]# yum install bind

[root@localhost ~]# service named restart
停止 named [确定]
Generating /etc/rndc.key:
新开窗口输入:
[root@localhost ~]# rndc-confgen -r /dev/urandom -a
wrote key file "/etc/rndc.key"
[root@localhost ~]# service named restart
停止 named [确定]
启动 named [确定]
[root@localhost ~]#
在安装bind-chroot的情况下,配置文件保存在/var/named/chroot/etc/目录下
[root@localhost ~]# cd /var/named/chroot/etc/
[root@localhost etc]# vi named.conf
named.conf的配置文件如下:
// 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"; #服务器工作目录,配置文件相对路径
dump-file "/var/named/data/cache_dump.db"; #默认服务器存放数据库文件
statistics-file "/var/named/data/named_stats.txt"; #默认统计信息路径
memstatistics-file "/var/named/data/named_mem_stats.txt"; #默认内存使用统计文件
allow-query { any; }; #可查询主机
allow-query-cache { any; }; #缓存
recursion yes; #是否允许递归查询
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;
// };
//};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
channel gsquery {
file "data/query.log" versions 3 size 20m;
severity info;
print-time yes;
print-category yes;
print-severity yes;
};
category queries { gsquery; };
};
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
到此基本上DNS服务器可以跑起来了。哦,不要忘记去把/etc/resolv.conf修改为自己这台服务器的IP哦!~下面开始创建域以及域文件。
可以直接修改named.conf,也可以在named.rfc1912.zones下面创建,我喜欢在named.rfc1912.zones下面创建。
[root@localhost etc]# vi /var/named/chroot/etc/named.rfc1912.zones
OR
[root@localhost etc]# vi /etc/named.rfc1912.zones
均可修改,我们创建一个a.com的域
type master;
file "a.com.zone";
allow-update { none; };
};
然后在
[root@localhost etc]# cd /var/named/chroot/var/named/
OR
[root@localhost etc]# cd /var/named/
创建一个文件名为a.com.zone的正向区域文件。
[root@localhost named]# vi /var/named/a.com.zone
a.com.zone的内容如下
$TTL 600
@ IN SOA ns.a.com admin.a.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
IN NS ns
IN A 192.168.1.250
IN AAAA ::1
www IN A 192.168.1.191
ns IN A 192.168.1.250
qwer IN A 4.3.2.1
注意第二行哦!!@ IN SOA a.com admin.a.com.是非常重要的哦!~
然后我们再来创建一个反向区域文件。
首先在named.rfc1912.zones创建一个反向区域
type master;
file "a.com.zone";
allow-update { none; };
};
zone "1.168.192.in-addr.arpa" IN { #这个是反向
type master;
file "192.168.1.zone";
allow-update { none; };
};
然后再来创建一个名字为192.168.1.zone的文件。
[root@localhost named]# vi /var/named/192.168.1.zone
@ IN SOA a.com admin.a.com. (
0 ; serial
1D ; refresh
1H ; retry
1W ; expire
3H ) ; minimum
NS @
A 127.0.0.1
AAAA ::1
250 IN PTR ns.a.com.
1.2.3.4 IN PTR qwer.a.com.
基本创建完成,经过测试正向、反向都正确。参考了很多网络文章,不一一列举,本地配置成功。
哦,对了。不要忘记开启防火墙的TCP、UDP 53端口哦!!
[root@localhost ~]# vi /etc/sysconfig/iptables
添加如下内容:
-A INPUT -m state --state NEW -m udp -p udp --dport 53 -j ACCEPT
