centos搭建dns服务器

过程

1. 安装bind

yum install -y bind

2. 修改配置文件

1. /etc/name.conf

将配置文件改成下图的样子,主要是箭头指向的地方.

2. /etc/name.rfc1912.zones

zone "test.com" IN {
        type master;
        file "test.com.zone";
        allow-update { none; };
};
zone "171.168.192.in-addr.arpa" IN {
        type master;
        file "192.168.171.zone";
        allow-update { none; };
};

3. 添加对应域的正反向解析文件

cp -p /var/named/named.localhost /var/named/test.com.zone #正向
cp -p /var/named/named.empty /var/named/192.168.171.zone #反向

4. 修改解析文件的内容

vim /var/named/test.com.zone:

$TTL 1D
@       IN SOA  test.com. rname.invalid. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS     dns.test.com
        MX 3 mail.test.com
dns IN A 192.168.171.23
www IN A 192.168.171.24
mail IN A 192.168.171.25
* A 192.168.171.77

vim /var/named/192.168.171.zone

$TTL 3H
@       IN SOA  test.com. rname.invalid. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      dns.test.com
        MX 3 mail.test.com
23 PTR dns.test.com
24 PTR www.test.com
25 PTR mail.test.com
* PTR xxx.test.com

结果检验

echo name server 192.168.171.141 > /etc/resolv.conf
nslookup www.test.com
