环境:linux
软件:bind97,bind97-utils, bind97-libs
ip:192.168.192.130;192.168.192.131
----------------------------------------------------------------------------------------------------------------
用命令判断以上软件是否安装成功
yum list all | grep "bind.*install"
当上面的软件全部安装成功之后,我们开始进行linux-dns缓存服务器的搭建
mv /etc/named.conf
/etc/named.conf.back--------->备份dns的原配置文件
/etc/named.conf.back--------->备份dns的原配置文件
----------------------------------------------------------------------------------------------------------------
默认的几个目录
/etc/named.conf(定义域以及对应的资源记录路径)
/var/named(资源类型记录)
/named.ca(根域rrt)
/named.localhost(本机rrt)
/named.loopback(本机反向rrt)
---------------------------------------------------------------------------------------------------------------
DNS(domain name system域名解析系统)
作用:
正向: IP----------->域名
反向: 域名----------->IP
资源记录类型
1、SOA(起始授权服务)
2、NS(名称服务器)
3、MX(邮件服务)
4、CNAME(别名)
5、A (正向映射)
6、PTR(反向映射)
--------------------------------------------------------------------------------------------------------------
1.编辑配置文件
--------------------------------------------------------------------------------------------------
vim /etc/named.conf
定义默认的目录:
options {
directory "/var/named";
};
定义根区域
zone "." IN {
type hint;
file "named.ca";
};
定义本地区域
zone "localhost" IN {
type master;
file "named.localhost";
};
定义本地反区域
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.loopback";
};
定义自己的区域
zone "huwentao.com" IN {
type master;
file "named.huwentao";
};
定义自己的反区域
zone "192.168.192.in-addr.arpa." IN {
type master;
file "named.192.168.192.in-addr.arpa";
};
---------------------------------------------------------------------------------------------------------------
2.编辑自己的区域文件
------------------------------------------------------------------------------------------------------------
vim /var/named/named.huwentao
$TTL 600

3.编辑反区域配置文件
------------------------------------------------------------------------------------------------------------
vim
/var/named/named.192.168.192.in-addr-arpa
/var/named/named.192.168.192.in-addr-arpa
$TTL 600

---------------------------------------------------------------------------------------------------------------
以上文件配置成功之后
启动服务
service named start
dig -t ns
huwentao.com
huwentao.com
dig -x 192.168.192.1
搭建小型的内网dns服务器成功。
