上一篇讲了DNS的基础相关以及一个简单的DNS搭建过程，今天更加深入的讲一讲DNS的主从复制、子域授权以及视图功能。
大纲
一、DNS主从复制
二、DNS子域授权
三、DNS视图及日志系统
四、DNS性能测试工具queryperf
一、DNS主从复制
环境准备
主DNS 172.16.1.111 soysauce
从DNS 172.16.1.110 CentOS5
1、首先建立主DNS
[root@soysauce ~]# yum install -y "bind" "bind-utils" # 安装bind和bind-utils
[root@soysauce ~]# mv /etc/named.conf{,.back} # 备份系统自带的配置文件
[root@soysauce ~]# vim /etc/named.conf # 编辑主配置文件
[root@soysauce named]# cat /etc/named.conf
options {
directory "/var/named";
allow-recursion { 172.16.0.0/16; }; # 定义允许递归的网段
notify yes; # 开启通知功能
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "named.localhost";
allow-transfer { none; }; # 不允许区域传送
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
allow-transfer { none; }; # 不允许区域传送
};
zone "" IN {
type master;
file ".zone";
allow-transfer { 172.16.1.110; }; # 定义只允许从DNS区域传送
};
zone "-addr.arpa" {
type master;
file "172.16.1.zone";
allow-transfer { 172.16.1.110; }; # 定义只允许从DNS区域传送
};
[root@soysauce ~]# cd /var/named/

4、增加主DNS反向解析记录，测试是否能通知从DNS
[root@soysauce named]# vim 172.16.1.zone [root@soysauce named]# tail -1 172.16.1.zone 114 IN PTR bbs.. # 新增一条A记录 [root@soysauce named]# service named reload Reloading named: [ OK ] [root@soysauce named]# tail /var/log/messages Dec 11 14:22:15 CentOS6 named[9278]: using default UDP/IPv4 port range: [1024, 65535] Dec 11 14:22:15 CentOS6 named[9278]: using default UDP/IPv6 port range: [1024, 65535] Dec 11 14:22:15 CentOS6 named[9278]: sizing zone task pool based on 5 zones Dec 11 14:22:15 CentOS6 named[9278]: Warning: 'empty-zones-enable/disable-empty-zone' not set: disabling RFC 1918 empty zones Dec 11 14:22:15 CentOS6 named[9278]: reloading configuration succeeded Dec 11 14:22:15 CentOS6 named[9278]: reloading zones succeeded Dec 11 14:22:15 CentOS6 named[9278]: zone -addr.arpa/IN: loaded serial 2015121002 Dec 11 14:22:15 CentOS6 named[9278]: zone -addr.arpa/IN: sending notifies (serial 2015121002) Dec 11 14:22:15 CentOS6 named[9278]: client 172.16.1.110#41576: transfer of '-addr.arpa/IN': AXFR-style IXFR started Dec 11 14:22:15 CentOS6 named[9278]: client 172.16.1.110#41576: transfer of '-addr.arpa/IN': AXFR-style IXFR ended # 可以看到已然传送 [root@CentOS5 slaves]# cat 172.16.1.zone # 再来看从DNS $ORIGIN . $TTL 86400 ; 1 day -addr.arpa IN SOA ns1.. admin..

注意：得配置iptables和selinux以及区域数据文件中从DNS的定义，不然可能导致无法实现主从复制。
5、增加本地rndc控制
[root@soysauce ~]# rndc-confgen > /etc/rndc.conf # 生成rndc配置文件
[root@soysauce ~]# vim /etc/rndc.conf # 将后半段注释部分追加至/etc/named.conf文件中
[root@soysauce ~]# tail /etc/named.conf # 可以看到已然追加成功
# key "rndc-key" {
# algorithm hmac-md5;
# secret "zcuT2H5UyUdG/1maGgMTYg==";
# };
#
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };
# End of named.conf
[root@soysauce ~]# vim /etc/named.conf # 去掉至倒数第二行的开头注释#号及空白
[root@soysauce ~]# tail /etc/named.conf
key "rndc-key" {
algorithm hmac-md5;
secret "zcuT2H5UyUdG/1maGgMTYg==";
};
controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};
#End of named.conf
[root@soysauce ~]# rm /etc/rndc.key # 删除系统自带的key
[root@soysauce ~]# service named restart

1、首先在上面那个主DNS中添加子域one..和two..
[root@soysauce named]# vim .zone [root@soysauce named]# cat .zone $TTL 86400 @ IN SOA ns1.. admin.. ( 2015121006 # 此处应该改变，+1 3H 10M 1D 2D ) IN NS ns1 IN NS ns2 IN MX 10 mail ns1 IN A 172.16.1.111 ns2 IN A 172.16.1.110 mail IN A 172.16.1.115 www IN A 172.16.1.112 www IN A 172.16.1.113 ftp IN CNAME www bbs IN A 172.16.1.114 one IN NS ns1.one # 添加one子域的NS记录和对应的A记录 ns1.one IN A 172.16.1.102 two IN NS ns2.one # 添加two子域的NS记录和对应的A记录 ns1.two IN A 172.16.1.103 [root@soysauce named]# service named reload # 重读配置文件及区域数据文件 Reloading named: [ OK ] [root@soysauce named]# tail /var/log/messages Dec 11 18:03:17 CentOS6 named[10286]: using default UDP/IPv6 port range: [1024, 65535] Dec 11 18:03:17 CentOS6 named[10286]: sizing zone task pool based on 5 zones Dec 11 18:03:17 CentOS6 named[10286]: Warning: 'empty-zones-enable/disable-empty-zone' not set: disabling RFC 1918 empty zones Dec 11 18:03:17 CentOS6 named[10286]: reloading configuration succeeded Dec 11 18:03:17 CentOS6 named[10286]: reloading zones succeeded Dec 11 18:03:17 CentOS6 named[10286]: zone /IN: two./NS 'ns2.one.' has no SIBLING GLUE address records (A or AAAA) Dec 11 18:03:17 CentOS6 named[10286]: zone /IN: loaded serial 2015121006 Dec 11 18:03:17 CentOS6 named[10286]: zone /IN: sending notifies (serial 2015121006) Dec 11 18:03:17 CentOS6 named[10286]: client 172.16.1.110#43029: transfer of '/IN': AXFR-style IXFR started Dec 11 18:03:17 CentOS6 named[10286]: client 172.16.1.110#43029: transfer of '/IN': AXFR-style IXFR ended # 已通知从DNS完成区域传送
2、查看从DNS上.区域数据文件是否同步
[root@CentOS5 slaves]# pwd /var/named/slaves [root@CentOS5 slaves]# cat .zone $ORIGIN . $TTL 86400 ; 1 day IN SOA ns1.. admin.. ( 2015121006 ; serial # 序列号已经发生改变 10800 ; refresh (3 hours) 600 ; retry (10 minutes) 86400 ; expire (1 day) 172800 ; minimum (2 days) ) NS ns1.. NS ns2.. MX 10 mail.. $ORIGIN . bbs A 172.16.1.114 ftp CNAME www mail A 172.16.1.115 ns1 A 172.16.1.111 ns2 A 172.16.1.110 one NS ns1.one $ORIGIN one.. ns1 A 172.16.1.102 $ORIGIN . two NS ns2.one $ORIGIN two.. ns1 A 172.16.1.103 # 可以看到one和two两个子域都已然同步 $ORIGIN . www A 172.16.1.112 A 172.16.1.113
3、配置子域one..的DNS服务器

注意：/etc/named.conf和/var/named目录下的区域数据文件的属主属组要为root:named，否则将无法正常解析
5、增加父域解析(转发域)
[root@node1 named]# vim /etc/named.conf
[root@node1 named]# tail -5 /etc/named.conf
zone "" IN {
type forward; # 如果是.域，则转发给172.16.1.111解析
forward first;
forwarders { 172.16.1.111; };
};
[root@node1 named]# named-checkconf
[root@node1 named]# service named reload
Reloading named: [ OK ]
[root@node1 named]# nslookup

Default server: 172.16.1.102
Address: 172.16.1.102#53
> set q=A
> www. # 查询父域内www主机的A记录
Server: 172.16.1.102

Non-authoritative answer:

Address: 172.16.1.113 # 可以看到已然解析出来，虽然是非权威应答
Name: www.
Address: 172.16.1.112
> exit三、DNS视图及日志系统
1、首先建立一个DNS服务器
[root@soysauce ~]# yum install -y "bind" "bind-utils"
2、编辑主配置文件/etc/named.conf，定义视图
[root@soysauce ~]# mv /etc/named.conf{,.back} # 备份系统自带的主配置文件
[root@soysauce ~]# vim /etc/named.conf # 自行编辑一个主配置文件
[root@soysauce ~]# ll /etc/named.conf
-rw-r--r-- 1 root root 412 Dec 11 19:08 /etc/named.conf
[root@soysauce ~]# chown .named /etc/named.conf
[root@soysauce ~]# chmod 640 named.conf
[root@soysauce ~]# ll /etc/named.conf
-rw-r----- 1 root named 412 Dec 11 19:08 /etc/named.conf
[root@soysauce ~]# cat /etc/named.conf
acl innet {
172.16.0.0/16;
127.0.0.0/8;
};
options {
directory "/var/named";
allow-recursion { innet; };
};
view telecom { # 一旦定义视图，则所有的区域都必须定义在视图中
match-clients { innet; };
zone "" IN {
type master;
file "telecom..zone";
};
};
view unicom {
match-clients { any; };
zone "" IN {
type master;
file "unicom..zone";
};
};
[root@soysauce etc]# named-checkconf # 检查配置文件是否有语法错误3、编辑区域数据文件
[root@soysauce named]# vim telecom..zone [root@soysauce named]# cat telecom..zone # telecom来源的区域数据文件 $TTL 86400 @ IN SOA ns1.. admin.. ( 2015121101 1H 10M 1D 1D ) IN NS ns1 ns1 IN A 172.16.1.111 www IN A 172.16.1.110 [root@soysauce named]# ll telecom..zone -rw-r--r-- 1 root root 173 Dec 11 19:23 telecom..zone [root@soysauce named]# chown .named telecom..zone [root@soysauce named]# chmod 640 telecom..zone [root@soysauce named]# ll telecom..zone -rw-r----- 1 root named 173 Dec 11 19:23 telecom..zone [root@soysauce named]# cp -p telecom..zone unicom..zone [root@soysauce named]# vim unicom..zone [root@soysauce named]# cat unicom..zone # unicom来源的区域数据文件 $TTL 86400 @ IN SOA ns1.. admin..

4、启动named服务
[root@soysauce named]# service named start Starting named: [ OK ] [root@soysauce named]# netstat -tunlp Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 172.16.1.111:53 0.0.0.0:* LISTEN 10623/named tcp 0 0 127.0.0.1:53 0.0.0.0:* LISTEN 10623/named tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 1631/sshd tcp 0 0 :::80 :::* LISTEN 8414/httpd tcp 0 0 :::22 :::* LISTEN 1631/sshd udp 0 0 172.16.1.111:53 0.0.0.0:* 10623/named udp 0 0 127.0.0.1:53 0.0.0.0:* 10623/named [root@soysauce named]# tail /var/log/messages Dec 11 19:33:16 CentOS6 named[10623]: automatic empty zone: view unicom: 8.B.D.0.1.0.0.2.IP6.ARPA Dec 11 19:33:16 CentOS6 named[10623]: none:0: open: /etc/rndc.key: file not found Dec 11 19:33:16 CentOS6 named[10623]: couldn't add command channel 127.0.0.1#953: file not found Dec 11 19:33:16 CentOS6 named[10623]: none:0: open: /etc/rndc.key: file not found Dec 11 19:33:16 CentOS6 named[10623]: couldn't add command channel ::1#953: file not found Dec 11 19:33:16 CentOS6 named[10623]: zone /IN/telecom: loaded serial 2015121101 Dec 11 19:33:16 CentOS6 named[10623]: managed-keys-zone ./IN/telecom: loaded serial 0 Dec 11 19:33:16 CentOS6 named[10623]: zone /IN/unicom: loaded serial 2015121101 Dec 11 19:33:16 CentOS6 named[10623]: managed-keys-zone ./IN/unicom: loaded serial 0 Dec 11 19:33:16 CentOS6 named[10623]: running
