BIND安装配置（主从）
我的系统环境：centos 5.2
作者：哈密瓜
主：
我采用的是yum安装
[root@linux src]#yum -y install bind*
生成rndc控制命令的key文件
[root@linux usr]# sbin/rndc-confgen > /etc/rndc.conf
从rndc.conf文件中提取named.conf用的key
[root@linux usr]# cd /etc
[root@linux etc]# tail -10 rndc.conf | head -9 | sed s/#\ //g >
/var/named/chroot/etc/named.conf
自动在/var/named/chroot/etc下生成named.conf文件
进入/var/named/chroot/etc
[root@linux etc]# cd /var/named/chroot/etc
现在named.conf文件中有了rndc-key区段
[root@linux etc]# more named.conf
key "rndc-key" {
algorithm hmac-md5;
secret "Nd0nLoL8t4Mv0iSpqP1noA==";
};
controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};
然后我们来完善它：
[root@linux etc]#vi named.conf
options {
directory "/var/named";
};
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
};
zone "learningsky.org" IN {
type master;
file "learningsky.zone";
allow-transfer { 192.168.22.155 ; }; //192.168.22.155为本机网关
notify yes;
also-notify { 192.168.22.155 ; }; //使用notify指令会自动通知所有这个域的所有在
ns记录上的机器，also-notify指令可以用来通知所有不在ns记录上的dns服务器.
};
zone "22.168.192.in-addr.arpa" IN {
type master;
file "22.168.192";
allow-transfer { 192.168.22.155 ; };
notify yes;
also-notify { 192.168.22.155 ; };
};
key "rndc-key" {
algorithm hmac-md5;
secret "Nd0nLoL8t4Mv0iSpqP1noA==";
};
controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};
进入/var/named/chroot/var/named
[root@linux etc]# cd /var/named/chroot/var/named
建立localhost.zone文件
[root@linux named]#vi localhost.zone
$TTL 86400
$ORIGIN localhost.
@ 1D IN SOA @ root (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
1D IN NS @
1D IN A 127.0.0.1
建立named.local文件
[root@linux named]#vi named.local
$TTL 86400
@ IN SOA localhost. root.localhost. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS localhost.
1 IN PTR localhost.
dig命令直接生成named.ca文件
[root@linux named]#dig > named.ca
建立learningsky.org域名正向解析文件
[root@linux named]#vi learningsky.zone
$TTL 86400
$ORIGIN learningsky.org.
@ 1D IN SOA dns.learningsky.org. root.mail.learningsky.org.

1D )
1D IN NS dns.learningsky.org.
1D IN MX 5 mail.learningsky.com.
dns IN A 192.168.22.150 //192.168.22.150为本机IP
mail IN A 192.168.22.150
www IN A 192.168.22.150
建立learningsky.org域名反向解析文件
[root@linux named]#vi 22.168.192
$TTL 86400
@ IN SOA dns.learningsky.org. root.mail.learningsky.org.(
20031001;

@ IN NS dns.learningsky.org.
150 IN PTR dns.learningsky.org.
150 IN PTR mail.learningsky.org.
150 IN PTR www.learningsky.org.
[root@linux named]#netstat -an |grep :53

修给reslov.conf
[root@linux named]#vi /etc/reslov.conf

# To use db, put the "db" in front of "files" for entries you want to be

# Example:
#passwd: db files nisplus nis
#shadow: db files nisplus nis
#group: db files nisplus nis
passwd: files

[root@linux etc]# more host.conf
order hosts,bind
启动named

主DNS配置完成。
从：
安装跟主的一样，不同的就是named.conf
named.conf内容：
options {
directory "/var/named";
};
zone "." IN {
type hint;
file "named.root";
};
zone "localhost" IN {
type master;
file "localhost.zone";
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
};
zone "learningsky.org" IN {
type slave;
file "learningsky.zone";
masters { 192.168.22.150; };
};
zone "22.168.192.in-addr.arpa" IN {
type slave;
file "22.168.192";
masters { 192.168.22.150; };
};
key "rndc-key" {
algorithm hmac-md5;
secret "80hKqo5bkGMAqHqeAlaLCA==";
};
controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "rndc-key"; };
};
注：
1、主从同步的两台机器要在同一个时区，时间相差不要太大。
2、主的dns服务器在修改了正向解析文件跟反向分解析文件时，要修改相应的 serial（通常
是加数值，这个值必须主的要大于从的，要不同步不了）
3、/var/named/chroot这个文件的宿主要是named，不是那权限other也要是7
4、红色字体一定要注意，同步关键……
