Linux 搭建DNS服务器

﹏ヽ暗。殇╰゛Y 2022-08-07 02:37 254阅读 0赞

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
