首先要成功安裝Centos操做系統,最新版本是Centos 6.4版本,最小化安裝。 html
[root@localhost named]# ifconfig -a linux

能夠看到本地網卡是eth1和lookback,編輯eth1網卡。 web
[root@localhost named]# vi /etc/sysconfig/network-scripts/ifcfg-eth1 數據庫
DEVICE=eth1 #網卡設備名稱
BOOTPROTO=static #靜態IP
IPADDR=192.168.1.251 #靜態ip地址
NETMASK=255.255.255.0 #子網掩碼
GATEWAY=192.168.1.1 #網關
若是配置正確的狀況是,如今是能夠上網的,ping 一個ip地址測試下。可是沒法進行域名解析,所以須要設置本機的dns。
[root@localhost named]# vi /etc/resolv.conf 緩存
加入內容: 服務器
nameserver 8.8.8.8 #DNS服務器
nameserver 8.8.4.4 #備用DNS服務器
此時,網絡已經配置完畢,讓咱們開啓bind配置之旅吧! 網絡
[root@localhost ~]# yum install bind

[root@localhost ~]# service named restart
中止 named [肯定]
Generating /etc/rndc.key:
新開窗口輸入:
[root@localhost ~]# rndc-confgen -r /dev/urandom -a
wrote key file "/etc/rndc.key"
[root@localhost ~]# service named restart
中止 named [肯定]
啓動 named [肯定]
[root@localhost ~]#
在安裝bind-chroot的狀況下,配置文件保存在/var/named/chroot/etc/目錄下
[root@localhost ~]# cd /var/named/chroot/etc/
[root@localhost etc]# vi named.conf
named.conf的配置文件以下: oracle
//
// 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"; #服務器工做目錄,配置文件相對路徑
dump-file "/var/named/data/cache_dump.db"; #默認服務器存放數據庫文件
statistics-file "/var/named/data/named_stats.txt"; #默認統計信息路徑
memstatistics-file "/var/named/data/named_mem_stats.txt"; #默認內存使用統計文件
allow-query { any; }; #可查詢主機
allow-query-cache { any; }; #緩存
recursion yes; #是否容許遞歸查詢
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服務器能夠跑起來了。哦,不要忘記去把/etc/resolv.conf修改成本身這臺服務器的IP哦!~下面開始建立域以及域文件。 dom
能夠直接修改named.conf,也能夠在named.rfc1912.zones下面建立,我喜歡在named.rfc1912.zones下面建立。 tcp
[root@localhost etc]# vi /var/named/chroot/etc/named.rfc1912.zones
OR
[root@localhost etc]# vi /etc/named.rfc1912.zones
都可修改,咱們建立一個a.com的域
zone "a.com" IN {
type master;
file "a.com.zone";
allow-update { none; };
};
而後在
[root@localhost etc]# cd /var/named/chroot/var/named/
OR
[root@localhost etc]# cd /var/named/
建立一個文件名爲a.com.zone的正向區域文件。
[root@localhost named]# vi /var/named/a.com.zone
a.com.zone的內容以下
$TTL 1D
$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.是很是重要的哦!~
而後咱們再來建立一個反向區域文件。
首先在named.rfc1912.zones建立一個反向區域
zone "a.com" IN { #這個是正向
type master;
file "a.com.zone";
allow-update { none; };
};
zone "1.168.192.in-addr.arpa" IN { #這個是反向
type master;
file "192.168.1.zone";
allow-update { none; };
};
而後再來建立一個名字爲192.168.1.zone的文件。
[root@localhost named]# vi /var/named/192.168.1.zone
$TTL 1D
@ 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.
基本建立完成,通過測試正向、反向都正確。參考了不少網絡文章,不一一列舉,本地配置成功。
哦,對了。不要忘記開啓防火牆的TCP、UDP 53端口哦!!
[root@localhost ~]# vi /etc/sysconfig/iptables
添加以下內容:
-A INPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT
-A INPUT -m state --state NEW -m udp -p udp --dport 53 -j ACCEPT
