linux+bind9.4.1 配置主備dns同步

bind9.4.1下載地址：http://ftp.isc.org/isc/bind9/9.4.1/bind-9.4.1.tar.gz

下載bind-9.4.1.tar.gz 放到/usr/local/src/目錄下

# tar zxvf bind-9.4.1.tar.gz

# cd bind-9.4.1

# ./configure --prefix=/usr/local/named --enable-threads

# make

# make install

# cd /usr/local/named/etc

建立主dns IP：1.2.3.4 域名：ns1.XXX.com

# ../sbin/rndc-confgen

copy下面註釋的部分代碼,並去掉註釋，修改rndc-key為ns1，有兩處啊。。。再把代碼加入named.conf

# key "rndc-key" {
# algorithm hmac-md5;
# secret "XXXXXXXXXXXXXXXXXXXXXXX";
# };
#
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };



建立named.conf

例子：

# vi named.conf

options {
directory "/usr/local/named/etc/";
};

logging {
category lame-servers { null; };
};

key "ns1" {
algorithm hmac-md5;
secret "XXXXXXXXXXXXXXXXXXXXXXX";
};

controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "ns1"; };
};
zone "." IN {
type hint;
file "named.ca";
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "XXX.com" IN {
type master;
file "db.XXX.com";
};
zone "3.2.1.in-addr.arpa" IN {
type master;
file "named.rev";
};

生成named.ca文件

# dig > named.ca

named.ca例子：

; This file holds the information on root name servers needed to
; initialize cache of Internet domain name servers
; (e.g. reference this file in the "cache . "
; configuration file of BIND domain name servers).
;
; This file is made available by InterNIC registration services
; under anonymous FTP as
; file /domain/named.root
; on server FTP.RS.INTERNIC.NET
; -OR- under Gopher at RS.INTERNIC.NET
; under menu InterNIC Registration Services (NSI)
; submenu InterNIC Registration Archives
; file named.root

啟動bind

# /usr/local/named/sbin/named -gc /usr/local/named/etc/named.conf

建立備dns IP：5.6.7.8 域名：ns2.XXX.com

# ../sbin/rndc-confgen

copy下面註釋的部分代碼,並去掉註釋，修改rndc-key為ns2，有兩處啊。。。再把代碼加入named.conf

# key "rndc-key" {
# algorithm hmac-md5;
# secret "XXXXXXXXXXXXXXXXXXXXXXX";
# };
#
# controls {
# inet 127.0.0.1 port 953
# allow { 127.0.0.1; } keys { "rndc-key"; };
# };



建立named.conf

例子：

# vi named.conf

options {
directory "/usr/local/named/etc/";
};

logging {
category lame-servers { null; };
};

key "ns2" {
algorithm hmac-md5;
secret "XXXXXXXXXXXXXXXXXXXXXXX";
};

controls {
inet 127.0.0.1 port 953
allow { 127.0.0.1; } keys { "ns2"; };
};
zone "." IN {
type hint;
file "named.ca";
};

zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};

zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "XXX.com" IN {
type s;
file "db.XXX.com";
masters { 1.2.3.4; };
};
zone "3.2.1.in-addr.arpa" IN {
type master;
file "named.rev";
masters {1.2.3.4; };
};

建立named.ca,localhost.zone,named.local文件,內容全部同主dns一樣

# dig > named.ca

# vi localhost.zone

# vi named.local

啟動備dns，這時個從主dns自動同步主DNS的內容。自動在你定義的工作目錄內生成數據文件

# /usr/local/named/sbin/named -gc /usr/local/named/etc/named.conf &
