本篇文章介紹了linux 如何配置dns，下面小編給大家介紹詳細(xì)的解決步驟

1. 安裝DNS所要的軟件包.
查看是否安裝bind軟件,在終端中輸入
[root@localhost root]# rpm -qa|grep bind
RedHat-config-bind-1.9.0-13
bind-9.2.1-16
bind-utils-9.2.1-16
ypbind-1.11-4
若出現(xiàn)以上的文字則表示安裝成功,若沒有出現(xiàn)以上東西插入正確的光盤,進(jìn)行安裝.或者通過下載源代碼進(jìn)行安裝。
2. 設(shè)定好IP地址與DNS
在終端中輸入netconfig,回車,在第一行中輸入IP,172.18.121.35.第二行輸入子網(wǎng)掩碼255.255.255.0第三行輸入網(wǎng)關(guān)地址:172.18.121.1,最后一行輸入DNS 172.18.121.35.再確定.再在終端中輸入下面的命令
[root@localhost root]#service network reload
[root@localhost root]#service network restart
通過ifconfig查看IP信息
3. 配置DNS
配置DNS正向搜索,配置文件如下:
[root@localhost root]#cp /var/named/localhost.zone /var/named/zljlinux.com
先復(fù)制本機(jī)DNS的一個(gè)配置模板文件,進(jìn)行修改,修改的部分是粗線表示
[root@localhost root]# vi /var/named/zljlinux.com
$TTL 86400
$ORIGIN zljlinux.com.
@ 1D IN SOA zljlinux.com. root.zljlinux.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS @
1D IN MX 5 mail.zljlinux.com.
www 1D IN A 172.18.121.35
mail 1D IN A 172.18.121.35
ftp 1D IN A 172.18.121.35
pop3 IN CNAME mail.zljlinux.com.
smtp IN CNAME mail.zljlinux.com.
保存退出,先按ESC ,再:wq.
配置DNS正向搜索,配置文件如下:
[root@localhost root]#cp /var/named/named.local /var/named/172.18.121.rev
先復(fù)制本機(jī)DNS的一個(gè)配置模板文件,進(jìn)行修改,修改的部分是粗線表示
[root@localhost root]# vi /var/named/172.18.121.rev
$TTL 86400
@ IN SOA linuxidc.com. root.linuxidc.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS linuxidc.com.
35 IN PTR www.linuxidc.com.
35 IN PTR mail.linuxidc.com.
35 IN PTR ftp.linuxidc.com.
配置本機(jī)DNS的一個(gè)主文件,安裝好后它有一個(gè)模板,修改它,修改的部分是粗線表示
[root@localhost root]# vi /etc/named.conf
// generated by named-bootconf.pl
options {
directory "/var/named";
/*
* If there is a firewall between you and nameservers you want
* to talk to, you might need to uncomment the query-source
* directive below. Previous versions of BIND always asked
* questions using port 53, but BIND 8.1 uses an unprivileged
* port by default.
*/
// query-source address * port 53;
};
//
// a caching only nameserver config
//
controls {
inet 127.0.0.1 allow { localhost; } keys { rndckey; };
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "linuxidc.com"IN{
type master;
file "linuxidc.com";
};
zone "121.18.172.in-addr.arpa"IN{
type master;
file "172.18.121.rev";
};
include "/etc/rndc.key";
"/etc/named.conf" [已轉(zhuǎn)換] 45L, 894C
配置本機(jī)的域名轉(zhuǎn)換程序的順序
[root@localhost root]# vi /etc/host.conf
order bind,hosts
multi off
trim linuxidc.com
[root@localhost root]# vi /etc/resolv.conf
nameserver 172.18.121.35
nameserver 218.196.42.2
namedsever 218.196.42.2
domain linuxidc.com
search www.linuxidc.com linuxidc.com
option nochecknames rotate
4. 啟動(dòng)named服務(wù).
[root@localhost root]#service named start
5. 檢查配置是否成功
[root@localhost root]# nslookup
Note: nslookup is deprecated and may be removed from future releases.
Consider using the `dig' or `host' programs instead. Run nslookup with
the `-sil[ent]' option to prevent this message from appearing.

35.121.18.172.in-addr.arpa name = mail.linuxidc.com.

ctrl +D退出
若出現(xiàn)上面的情況的文字表示已經(jīng)配置成功.
6. 其實(shí)在配置的過程中,查看自己是否配置正確可以通過named ?g 進(jìn)行查看你的配置文件到底錯(cuò)在那個(gè)地方,再進(jìn)行修改.
