CentOS7.4 配置DNS服務器

1.安裝bind軟件包

yum?install?-y?bind*

2.各配置文件路徑索引

/etc/named.conf?#主配置文件
/var/named/?#解析數據庫文件目錄
/etc/named.rfc1912.zones?#默認的解析區域文件

3.主配置文件的修改

#以下修改只是我做改動的地方?
vim?/etc/named.conf?
options?{
???????
#listen-on?port?53?{?127.0.0.1;?};?注釋掉該行表示在所有接口IP啟用53端口的監聽
???????
#listen-on-v6?port?53?{?::1;?};?關閉IPv6的監聽
???????
?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";
???????
?recursing-file??"/var/named/data/named.recursing";
????????
secroots-file???"/var/named/data/named.secroots";
????????
#allow-query?????{?localhost;?};?允許所有主機進行DNS查詢，默認只允許本地查詢?
zone?"example.com"?IN?{?
type?master;??
file?"example.com.zone"；?#如果不加絕對路徑的話，默認會將配置文件認為是在/var/named目錄內
?}；?????????
#include?"/etc/named.rfc1912.zones";?注釋掉該行
include?"/etc/named.root.key";

4.創建數據庫文件

cd?/var/named/?
cp?named.localhost?example.com.zone?#通過默認的區域文件創建一個
vim?example.com.zone?
$TTL?1D
@IN?SOAexample.com?dns.example.com.?
?????????????????????????????????????????????????(
0;?serial?
?????????????????????????????????????????????????1D;?refresh
?????????????????????????????????????????????????1H;?retry?
?????????????????????????????????????????????????1W;?expire?
?????????????????????????????????????????????????3H?);?minimum?
@????????INNSdns.example.com.?
dnsINA172.16.104.123
wwwINA172.16.104.123

5.重啟測試

systemctl?restart?named
[root@localhost?named]#?systemctl?status?named?#查看一下狀態?
cat?/etc/resolv.conf?#確定DNS地址?
#?Generated?by?NetworkManager?
nameserver?172.16.104.123???????????
[root@localhost?~]#?nslookup?www.example.com?
Server:172.16.104.123?
Address:172.16.104.123#53?
Name:www.example.com?
Address:?172.16.104.123
