切記用戶屬性和權限問題
chown -Rf named /var/named/chroot/var/named 可執行權限
selinux問題
[root@localhost named]# vi /etc/sysconfig/selinux
SELINUX=disabled
或者setup進入圖形界面 ---防火牆---selinux 禁用
Iptables問題
開啓dns解析端口53
Setup配置---定製
或者
vi /etc/sysconfig/iptables
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 53 -j ACCEPT
