Linux DNS配置

1.安装bind

#安装bind
yum install -y bind bind-chroot bind-utils

2.主配置文件

vi /etc/named.conf

#修改监听为本机IP
listen-on port 53 { 172.18.0.227; };
#允许所有人访问
allow-query     { any; };

3.添加域配置

vi /etc/named.rfc1912.zones

#域名配置 : 正向解析配置
zone "wanmagroup.com" IN {
        type master;
        file "named.wanmagroup.com.zone";
        allow-update { none; };
};

#反向解析配置
zone "0.18.172.in-addr.arpa" IN {
        type master;
        file "named.0.18.172.in.zone";
        allow-update { none; };
};

#正向配置解析文件 /var/named/named.wanmagroup.com.zone
$TTL 86400
@       IN      SOA     @       root. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        IN      NS      @
        IN      A       172.18.0.227
*       IN      A       172.18.0.227

#反向配置解析文件 /var/named/named.0.18.172.in.zone
$TTL 1D
@       IN SOA  @ root. (
                                        0       ; serial
                                        1D      ; refresh
                                        1H      ; retry
                                        1W      ; expire
                                        3H )    ; minimum
        NS      @
        A       172.18.0.227

4.检查配置

#检查主配置文件
named-checkconf

#检查正向配置文件
named-checkzone wanmagroup.com named.wanmagroup.com.zone

#检查反向配置文件
named-checkzone wanmagroup.com named.0.18.172.in.zone

5.启动服务器

#重启服务
systemctl restart named.service

#检查服务状态
systemctl status  named.service -l
