DNS主、从服务器的配置

所有服务器：关闭防火墙和安全机制
iptables -F
systemctl stop firewalld
setenforce 0

配置yum源

[root@ns2 ~]# umount -a

[root@ns2 ~]# mount /dev/sr0 /media

[root@ns2 ~]# cd /etc/yum.r*

[root@ns2 yum.repos.d]# mv C* a/

[root@ns2 yum.repos.d]# vim ./local.repo

[cdrom]
name=cdrom
baseurl=file:///media/
enabled=1
gpgcheck=0

[root@ns2 yum.repos.d]# yum -y clean all

 主服务器的配置：

[root@localhost ~]# yum -y install bind

[root@localhost ~]# vim /etc/resolv.conf 

 

[root@localhost ~]# vim /etc/hosts

[root@localhost ~]# vim /etc/named.conf 

 [root@localhost ~]# vim /var/named/crushlinux.zheng

 

[root@localhost ~]# cp /var/named/crushlinux.zheng /var/named/crushlinux.fan

[root@localhost ~]# vim /var/named/crushlinux.fan

[root@localhost ~]# chown :named /var/named/crushlinux.*

[root@localhost ~]# named-checkconf -z /etc/named.conf

[root@localhost ~]# named-checkzone crushlinux.com /var/named/crushlinux.zheng 

[root@localhost ~]# named-checkzone crushlinux.com /var/named/crushlinux.fan

[root@localhost ~]# systemctl restart named

从服务器配置：

[root@localhost ~]# yum -y install bind
[root@localhost ~]# cat /etc/resolv.conf

[root@ns2 ~]# vim /etc/hosts

[root@localhost ~]# cat /etc/named.conf 

 [root@ns2 ~]# systemctl restart named
