一般而言,dns服务都是很繁忙的,一台公网的dns会维护成千上万个zone,named服务不会轻易被重启,登陆dns服务器进行维护也有极大的风险,所以需要对named服务进行远程管理。
[root@hdss7-11 named]# cat /etc/rndc.key
key "rndc-key" {
algorithm hmac-sha256;
secret "lJULDN7O3rEJnyGVIItsD3XMN8nJ026f4sBTkKHb8JM=";
};
[root@hdss7-11 named]# rndc-confgen -r /dev/urandom
# Start of rndc.conf
key "rndc-key" {
algorithm hmac-md5;
secret "YcHr6Mdp/hFVnx+x81kELw==";
};
options {
default-key "rndc-key";
default-server 127.0.0.1;
default-port 953;
};
# End of rndc.conf
# Use with the following in named.conf, adjusting the allow list as needed:
# key "rndc-key" {
# algorithm hmac-md5;
# secret "YcHr6Mdp/hFVnx+x81kELw==";
# };
#
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf
[root@hdss7-11 ~]# vi /etc/named.conf
key "rndc-key" {
algorithm hmac-md5;
secret "YcHr6Mdp/hFVnx+x81kELw==";
};
controls {
inet 10.4.7.11 port 953
allow { 10.4.7.11;10.4.7.12; } keys { "rndc-key"; };
};
注意,这里需要配置一下controls段的acl,限定好哪些主机可以rndc管理DNS服务
[root@hdss7-11 ~]# systemctl restart named
[root@hdss7-11 ~]# netstat -nltup|grep 953
tcp 0 0 10.4.7.11:953 0.0.0.0:* LISTEN 20544/named
[root@hdss7-12~]#yum install bind -y
远程主机安装bind,因为rndc命令在bind包里(不需要启动named)
注意:使用rndc管理的主机上,都需要配置rndc.conf,且rndc-key要和DNS服务器保持一致
[root@hdss7-12 named]# vi /etc/rndc.conf
key "rndc-key" {
algorithm hmac-md5;
secret "YcHr6Mdp/hFVnx+x81kELw==";
};
options {
default-key "rndc-key";
default-server 10.4.7.11;
default-port 953;
};
[root@hdss7-12 named]# rm -f /etc/rndc.key

静态域zone文件
zone "od.com" IN {
type master;
file "od.com.zone";
allow-update { none; };
};
增、删、改、一条记录后
# rndc reload od.comzone
reload up-to-date
动态域文件
zone "host.com" IN {
type master;
file "host.com.zone";
allow-update { 10.4.7.11; };
};
增、删、改、一条记录后其实是直接可以生效的(去域数据文件都是named权限)
#rndc reload host.com
rndc: 'reload' failed: dynamic zone 无需reload而且报错
需要先 freeze 再 thaw
#rndc freeze host.com
#rndc thaw host.com
The zone reload and thaw was successful.
示例:
有rndc后可以手动变更区域数据文件
acl "someips" { //定义一个名为someips的ACL
10.0.0.1; 192.168.23.1; 192.168.23.15; //包含3个单个IP
};
acl "complex" { //定义一个名为complex的ACL
"someips"; //可以嵌套包含其他ACL
10.0.15.0/24; //包含10.0.15.0子网中的所有IP
!10.0.16.1/24; //非10.0.16.1子网的IP
{10.0.17.1;10.0.18.2;}; //包含了一个IP组
localhost; //本地网络接口IP(含实际接口IP和127.0.0.1)
};
allow-update { "someips"; };allow-transfer { "complex"; };...
view语句定义了视图功能。视图是BIND9提供的强大的新功能,允许DNS服务器根据客户端的不同,有区别地回答DNS查询,每个视图定义了一个被特定客户端子集见到的DNS名称空间。这个功能在一台主机上运行多个形式上独立的DNS服务器时特别有用。
view view_name [class] {
match-clients { address_match_list } ;
match-destinations { address_match_list } ;
match-recursive-only { yes_or_no } ;
[ view_option; ...]
[ zone-statistics yes_or_no ; ]
[ zone_statement; ...]
};
注:以下是内网DNS的view使用范例
acl "env-test" {
10.4.7.11;
};
acl "env-prd" {
10.4.7.12;
};
view "env-test" {
match-clients { "env-test"; };
recursion yes;
zone "od.com" {
type master;
file "env-test.od.com.zone";
};
};
view "env-prd" {
match-clients { "env-prd"; };
recursion yes;
zone "od.com" {
type master;
file "env-prd.od.com.zone";
};
};
view "default" {
match-clients { any; };
recursion yes;
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
};
注:以下特指公网智能DNS配置范例
//电信IP访问控制列表
acl "telecomip"{ telecom_IP; ... };
//联通IP访问控制列表
acl "netcomip"{ netcom_IP; ... };
view "telecom" {
match-clients { "telecomip"; };
zone "ZONE_NAME" IN {
type master;
file "ZONE_NAME.telecom.zone";
};
};
view "netcom" {

编辑主配置文件,修改以下几项,把53端口开放到公网
options {
listen-on port 53 { any; };
allow-query { any; };
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
dnssec-lookaside auto;
};
使用随便一台主机测试
[root@hdss7-12 ~]# dig -t A baidu.com @111.231.227.17 +short
220.181.38.148
39.156.69.79
这里可以查到百度,因为recursion 是开启的,但是在生产中,此选项一般为no
DNSSEC(DNS Security Extension)—-DNS安全扩展,主要是为了解决DNS欺骗和缓存污染问题而设计的一种安全机制。

在生成证书的目录对ZSK执行dnssec-dsfromkey命令,得到bkjf-inc.com的DS记录,这里我们使用比较长的那个
/var/named/chroot/var/named/dnssec-key/bkjf-inc.com
[root@VM_0_13_centos bkjf-inc.com]# dnssec-dsfromkey `grep -l zone-signing *key`
bkjf-inc.com. IN DS 53901 8 1 5E13F6C0ECEE84248C2543693CE7D8617920983B
bkjf-inc.com. IN DS 53901 8 2 3006068B784AFBBC67133F123A0C389514959FCB6CAB0032DB200F08E6E5C384
其中:
53901:关键标签,用于标识域名的DNSSEC记录,一个小于65535的整数值
8:生成签名的加密算法,8对应RSA/SHA-256
2:构建摘要的加密算法,2对应SHA-256
最后一段:摘要值,就是DS记录值
参考万网(阿里云)上关于dnssec配置的文档:参考文档
DS记录需要通过运营商提交到上级DNS的信任锚中,这里是通过万网的配置页面,提交到.com域
注意:要在阿里云上将该域名的dns服务器指向自定义DNS服务器:参考文档
dnssec需要定期轮转,所以需要经常变更签名,其中
ZSK轮转
建议每年轮转
KSK轮转
建议更新ssl证书后尽快轮转?
轮转方法:
$ cd /var/named/chroot/var/named/dnssec-key/bkjf-inc.com
$ dnssec-settime -I yyyy0101 -D yyyy0201 Kbkjf-inc.com.+008+53901
$ dnssec-keygen -S Kbkjf-inc.com.+008+53901
$ chgrp bind *
$ chmod g+r *.private
$ cd /var/named/chroot/var/named/dnssec-key/bkjf-inc.com
$ dnssec-settime -I yyyy0101 -D yyyy0201 Kbkjf-inc.com.+008+40759
$ dnssec-keygen -S Kbkjf-inc.com.+008+40759
$ chgrp bind *
$ chmod g+r *.private
注意:KSK轮转需要同步在万网上更新DS记录
