几个dns解析的笔记，以后用得着：
redhat6 dns服务器安装 正向 反向解析
1.安装bind包，由于6之后的caching-nameserver 已经整合到bind包里面了，所以不需要安装caching-nameserver了 但是6之前需要
yum install bind bind-utils bind-chroot bind-utils -y
named 服务 使用的配置文件：
1.主配置文件：
/etc/named.conf
cat /etc/named.conf:
[root@moban named]# cat /etc/named.conf
//
// named.conf
//
// Provided by Red Hat bind package to configure the ISC BIND named(8) DNS
// server as a caching only nameserver (as a localhost DNS resolver only).
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
options {
// listen-on port 53 { 127.0.0.1; };
listen-on port 53 { any; };
#listen-on-v6 port 53 { ::1; };
directory "/var/named";
dump-file "/var/named/data/cache_dump.db";
statistics-file "/var/named/data/named_stats.txt";
memstatistics-file "/var/named/data/named_mem_stats.txt";
//allow-query { localhost; };
allow-query { any; };
recursion yes;
dnssec-enable yes;
dnssec-validation yes;
forwarders {
8.8.8.8;
};
/* Path to ISC DLV key */
bindkeys-file "/etc/named.iscdlv.key";
managed-keys-directory "/var/named/dynamic";
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
zone "." IN {
type hint;
file "named.ca";
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
##
我尝试过更改
include "/etc/named.rfc1912.zones";
这个include文件，但是named启动的时候 会提示找不到文件，所以还是使用了原来的文件。
cat /etc/named.rfc1912.zones
[root@moban named]# cat /etc/named.rfc1912.zones
// named.rfc1912.zones:
//
// Provided by Red Hat caching-nameserver package
//
// ISC BIND named zone configuration for zones recommended by
// RFC 1912 section 4.1 : localhost TLDs and address zones
// and http://www.ietf.org/internet-drafts/draft-ietf-dnsop-default-local-zones-02.txt
// (c)2007 R W Franks
//
// See /usr/share/doc/bind*/sample/ for example named configuration files.
//
zone "localhost.localdomain" IN {
type master;
file "named.localhost";
allow-update { none; };
};
zone "localhost" IN {
type master;
file "named.localhost";
allow-update { none; };
};
zone "1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "1.0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
allow-update { none; };
};
zone "0.in-addr.arpa" IN {
type master;
file "named.empty";
allow-update { none; };
};
##这个新加的域名
##正向文件
zone "dengchao.55.com" IN {
type master;
file "dengchao.55.com.zone";
allow-update { none; };
};
##反向文件
zone "168.192.in-addr.arpa" IN {
type master;
file "168.192.zone";
allow-update { none; };
};
##正向文件
zone "dengwenyan.com" IN {
type master;
file "dengwenyan.com.zone";
allow-update { none; };
};
##反向文件 注意 取名格式：ip的前两位的倒叙
zone "16.172.in-addr.arpa" IN {
type master;
file "16.172.zone";
allow-update { none; };
};
## 由于named的主配置文件在 配置named的工作目录在/var/named,所以我们需要在/var/named下创建这4个文件 并且需要更改组为named
