Centos7 DNS服务

DNS解析

安装bind

yum -y install bind-chroot
systemctl restart named
systemctl enable named

修改主配置文件

vim /etc/named.conf
options {
        listen-on port 53 { any; };   #监听的端口的ip(ip可多个，any表示所有)
        listen-on-v6 port 53 { ::1; };
        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";
        allow-query     { any; };   #允许dns查询的客户机列表any表示所有

配置区域数据信息

vim /etc/named.rfc1912.zones
zone "linuxprobe.com" IN {  \\直接在末尾追加
        type master;
        file "linuxprobe.com.zone";
        allow-update { none; };
};

配置解析数据信息

cd /var/named
ls -al named.localhost
cp -a named.localhost linuxprobe.com.zone

vim linuxprobe.com.zone

• systemctl restart named

检查解析结果

nslookup
>www.linuprobe.com

若解析不成功
vim /etc/resolv.conf
nameserver 192.168.18.10

反向解析

配置区域数据信息

vim /etc/named.rfc1912.zones
zone "18.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.18.arpa";
};  

配置解析数据信息

cp -a named.loopback 192.168.18.arpa
vim 192.168.18.arpa

• systemctl restart named

检查解析结果

nslookup
192.168.18.10
