Linux搭建DNS服务器


系统环境：CentOS 6.5 mini
IP地址：192.168.100.100


1.安装相关软件包
# yum install -y bind* caching-nameserver


2.防火墙端口开放
# vi /etc/sysconfig/iptables
-AINPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT
-AINPUT -m state --state NEW -m udp -p udp --dport 53 -j ACCEPT
-AINPUT -m state --state NEW -m tcp -p tcp --dport 953 -j ACCEPT

# service iptables restart
# /etc/rc.d/init.d/iptables save


3.关闭selinux
# vi /etc/selinux/config
SELINUX=disabled


4.修改named.conf
# vi /etc/named.conf
listen-on port 53 { any; };
listen-on-v6 port 53 { any; };
allow-query     { any; };

5.在bind的主配置文件中添加该域

# vi /etc/named.rfc1912.zones
zone "baidu.com" IN{
    type master;
    file "baidu.com.zone";
};

zone "doiido.com" IN{
    type master;
    file "doiido.com.zone";
};

zone "1.10.in-addr.arpa" IN {
    type master;
    file "1.10.zone";
};

6.创建域的zone文件
（这里的文件名必须是和上面一样）
# cd /var/named
# touch baidu.com.zone
# touch doiido.com.zone
# touch 1.10.zone


7.编辑zone文件
# vi baidu.com.zone
$TTL 86400
@       IN SOA          ns.baidu.com. root (
                                        1       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
@       IN      NS      ns.baidu.com.
ns      IN      A       115.239.211.110
www     IN      A       115.239.211.110

# vi doiido.com.zone
$TTL 86400
@       IN SOA          ns.doiido.com. root (
                                        1       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
@       IN      NS      ns.doiido.com.
ns      IN      A       1.1.1.1
www     IN      A       1.1.1.1

# vi 1.10.zone
$TTL 86400
@       IN SOA           ns.doiido.com. ns.baidu.com. (
                                        12         ; serial
                                        28800      ; refresh
                                        14400      ; retry
                                        3600000    ; expire
                                        86400 )    ; minimum
@        IN      NS       ns.doiido.com.
1        IN      PTR      www.doiido.com.
110      IN      PTR      www.baidu.com.

8.修改刚才添加的域文件的权限
# chmod o+r /var/named/*


9.修改resolv.conf文件
# vi /etc/resolv.conf
nameserver 192.168.100.100


10.测试配置文件
# named-checkzone doiido.com /var/named/doiido.com.zone
# named-checkzone baidu.com /var/named/baidu.com.zone


11.重新启动named服务

# service named restart
