linux-dns的安装

發布時間：2024/4/11 linux 26 豆豆

生活随笔收集整理的這篇文章主要介紹了 linux-dns的安装小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

1.配置靜態IP地址

#vi /etc/sysconfig/network-scripts/ifcfg-eth0

DEVICE=eth0

BOOTPROTO=static

ONBOOT=yes

IPADDR=192.198.101.70

NETMASK=255.255.255.0

GATEWAY=192.168.101.254

#/etc/init.d/network restart

#ifconfig eth0

2.安裝dns，配置主dns服務器

2.1 安裝包

--安裝的DNS只是BIND 里的一個服務項

[root@mail ~]# yum install bind

[root@mail ~]# yum install bind-chroot

[root@mail ~]# yum install caching-nameserver –y

--作用caching-server和主配文件的模板

[root@mail ~]# yum list all |grep bind

This system is not registered with RHN.

RHN support will be disabled.

bind.i386????????????????????????????? 30:9.3.4-10.P1.el5??? installed?????????

bind-chroot.i386?????????????????????? 30:9.3.4-10.P1.el5??? installed???

　　安全目錄

dns 根目錄? /var/named/chroot

dns服務器主配置文件?? /var/named/chroot/etc

dns服務器區域文件（數據庫）?? /var/named/chroot/var/named?????

bind-libs.i386???????????????????????? 30:9.3.4-10.P1.el5??? installed?????????

--提供了實現域名解析功能必備的庫文件

bind-utils.i386??????????????????????? 30:9.3.4-10.P1.el5??? installed??

-- 提供了對DNS服務器的測試工具程序?????

ypbind.i386??????????????????????????? 3:1.19-11.el5???????? installed?????

2.2 修改配置文件

[root@mail ~]# cd /var/named/chroot/etc

[root@mail etc]# cp -p named.caching-nameserver.conf named.conf

[root@mail etc]# vim named.conf

--全局配置

options {

??????? listen-on port 53 { any; };--默認監聽本機地址

----tcp 53號端口是區域文件傳輸的，傳輸安全

----udp 53號端口是用來查詢的，速度較快

??????? allow-query???? { any; }; --允許進來查詢的客戶端

};

view localhost_resolver {

??????? match-clients????? { any; };

??????? match-destinations { any; }; --查詢的目標

??????? include "/etc/named.rfc1912.zones";

}；

2.3聲明區域

[root@mail ~]# cd /var/named/chroot/etc

[root@mail etc]# vim named.rfc1912.zones

--建立正向解析區域

zone "." IN {???????????????????? --指定根域

???????? type hint;

???????? file "named.ca";

???????? };

zone "bj.com" IN {????????????????? --指定本地域

??????? type master;

??????? file "bj.com.db";

??????? allow-update { none; };???????? --不允許動態更新

};

--建立反向解析區域

zone "101.168.192.in-addr.arpa" {?????????? --指定反向域

???????? type master;

???????? file "192.168.101.db";

???????? };

2.4產生數據庫文件(區域文件)

根域文件 /var/named/named.ca

正向區域文件 /var/named/localhost,zone

反向區域文件 /var/nsmed/named.local

正向和反向的文件的屬組默認選項則是named 如果不是需要修改

[root@mail named]#chgrp named bi.com.db

--建立正向區域文件

[root@mail named]# cp -p localhost.zone bj.com.db

[root@mail named]# vim bj.com.db

$TTL??? 86400

@?????????????? IN SOA? ns.bj.com.?????? root.126.com (

??????????????????????????????????????? 42????????????? ; serial (d. adams)

?????????????? –序列號，配置文件的修改版本，一般按年月日+序列號，定義為唯一的標示符。

??????????????????????????????????????? 3H????????????? ; refresh –更新周期（刷新頻率）

??????????????????????????????????????? 15M???????????? ; retry –重試間隔

??????????????????????????????????????? 1W????????????? ; expiry –過期時間（一周）

????? ??????????????????????????????????1D )??????????? ; minimum

??????????????? IN NS?????????? ns.bj.com.

ns????????????? IN A??????????? 192.168.101.70

mail??????????? IN A??????????? 192.168.101.70

pop3??????????? IN CNAME??????? mail

smtp?????????? ?IN CNAME??????? mail

imtp??????????? IN CNAME??????? mail

@?????????????? IN MX????? 10?? mail

--添加泛域名，實現一臺機器多個域名，沒有匹配的都對應4.4.4.4

*??????? IN?????? A????? 4.4.4.4

[root@mail named]# cp -p localhost.zone? 192.168.101.db

[root@mail named]# vim 192.168.101.db

$TTL??? 86400

@?????????????? IN SOA? ns.test.com.?????? root.126.com (

??????????????????????????????????????? 42????????????? ; serial (d. adams)

??????????????????????????????????????? 3H????????????? ; refresh

???????????????????????? ???????????????15M???????????? ; retry

??????????????????????????????????????? 1W????????????? ; expiry

??????????????????????????????????????? 1D )??????????? ; minimum

??????????????? IN NS?????????? ns.test.com.

77????????????? IN PRT????????? ns.test.com.??

???

--–ptr可以用ip省略，101.168.192.in-addr.rapa表192.168.101.77==77

2.5 dns指向

[root@mail etc]# vim /etc/resolv.conf

#search localdomain

nameserver 192.168.101.70

[root@mail named]# vim /etc/sysconfig/network

NETWORKING=yes

HOSTNAME=mail.bj.com

[root@mail etc]# vim /etc/hosts

127.0.0.1?????????????? localhost.localdomain localhost

192.168.101.70? mail.bj.com

--更改主機名

2.6 開啟服務解析

測試主配置文件named.conf

# named-checkconf???? （如果不顯示任何信息表示語法正確）

測試區域文件

# named-checkzone bj.com /var/named/chroot/var/named/bj.com.db

# named-checkzone 101.168.192.in-addr.arpa /var/named/chroot/var/named/192.168.101.db

BIND服務器的服務程序腳本名稱是named，默認沒有啟動，需手動設置。

#rpm -ql bind | grep init.d

/etc/rc.c/init.d/named

#chkconfig --level 35 named on

#chkconfig --list named

--服務也可以用下面的啟動

[root@mail named]# service named start

Starting named:??????????????????????????????????????????? [? OK? ]

[root@mail named]# chkconfig named on

[root@mail named]# rndc reload

server reload successful

[root@mail etc]# nslookup mail.bj.com

Server:???? 192.168.101.70

Address:??? 192.168.101.70#53

Name:?? mail.bj.com

Address: 192.168.101.70

[root@mail etc]# dig??? -t mx bj.com
