首先，我们需要按照以下步骤配置和安装好dns服务器
DNS server configuration
Install the bind packages using sudo:
$ sudo dnf install bind bind-utils -y
The /etc/named.conf configuration file is provided by the bind package to allow you to configure the DNS server.
Edit the /etc/named.conf file:
sudo vi /etc/named.conf
Look for the following line:
listen-on port 53 { 127.0.0.1; };
Add the IP address of your Master DNS server as follows:
listen-on port 53 { 127.0.0.1; 192.168.1.160; };
Look for the next line:
allow-query { localhost; };
Add your local network range. The example system uses IP addresses in the 192.168.1.X range. This is specified as follows:
allow-query { localhost; 192.168.1.0/24; };
Specify a forward and reverse zone. Zone files are simply text files that have the DNS information, such as IP addresses and host-names, on your system. The forward zone file makes it possible for the translation of a host-name to its IP address. The reverse zone file does the opposite. It allows a remote system to translate an IP address to the host name.
Look for the following line at the bottom of the /etc/named.conf file:
include "/etc/named.rfc1912.zones";
Here, you’ll specify the zone file information directly above that line as follows:
zone "dns01.fedora.local" IN {
type master;
file "forward.fedora.local";
allow-update { none; };
};
zone "1.168.192.in-addr.arpa" IN {
type master;
file "reverse.fedora.local";
allow-update { none; };
};
The forward.fedora.local and the file reverse.fedora.local are just the names of the zone files you will be creating. They can be called anything you like.
Save and exit.
接着我们需要按照自己的需要给几个特定的域名配置指定的zone文件。要知道每一个dns服务器都是按照自己的zone文件来解析域名的。
以下是给域名服务器配置访问gitlab.tuocad.com时，给解析到指定局域网的配置方法：
这是在/etc/named.conf文件中，指定访问gitlab.tuocad.com域名时去文件名为forward.tuocad.com文本文件中去寻找。
zone "gitlab.tuocad.com" IN {
type master;
file "forward.tuocad.com";
allow-update { none; };
};
默认情况下，域名服务器会在/var/named/目录下寻找zone文件。下面是/var/named/forward.tuocad.com的内容：
$TTL 86400
@ IN SOA gitlab.tuocad.com. root.tuocad.com. (
2011071001 ;Serial
3600 ;Refresh
1800 ;Retry
604800 ;Expire
86400 ;Minimum TTL
)
@ IN NS gitlab.tuocad.com.
@ IN A 192.168.3.4
在配置其他电脑使用此域名服务器时可以修改/etc/resolv.conf文件。在配置此文件时需要注意以下事项
To prevent this from happening, make /etc/resolv.conf immutable:
$ sudo chattr +i /etc/resolv.conf
If you want to set it back and allow it to be overwritten again:
$ sudo chattr -i /etc/resolv.conf
