Настройка DNS сервера в Сentos 7, РЕДОС 7.3​

Разворачиваем на госпитальной платформе bind server:

sudo yum -y install bind
sudo systemctl enable --now named
sudo firewall-cmd --permanent --zone=public --add-service=dns
sudo firewall-cmd --reload

Меняем DNS на внешнем интерфейсе на 127.0.0.1:

systemctl restart network

Добавляем зоны:

# /etc/named/mvsservice.ru.zone
$TTL 86400
@       IN  SOA     ns1.mvsservice.ru. admin.mvsservice.ru. (
        1      ;Serial
        3600    ;Refresh
        1800    ;Retry
        604800  ;Expire
        86400   ;Minimum TTL
)
@       IN      NS      ns1.mvsservice.ru.
ns1     IN      A       192.168.x.x

)
@       IN      NS      ns1.mvsservice.ru.
52       IN      PTR     mvsservice.ru

Редактируем /etc/named.conf
