1、bind dns
yum -y install bind bind-libs bind-utils
2、bind service
chkconfig named on
3、start bind service
service named start
注意：
1、创建key
rndc-confgen -r /dev/urandom -a
2、更改权限
chown root:named /etc/rndc.key
chmod 644 /etc/rndc.key
3、重启named服务
service named restart
rndc status
rndc reload
4、named.conf
/etc/named.conf
