Editor to share with you how to set up a DNS server under Linux, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

The establishment of reverse domain name conversion data files db.127.0.0 and db.192.11.56.

The reverse domain name translation data file is used to query the corresponding DNS host name according to the IP address, and each network segment has a data file.

I believe you all know the internal URL of "127.0.0". There is only one IP address: 127.0.0.1. The configuration example is:

@ IN SOA linux.site.com root.linux.site.com. (

2004080700

28800

14400

3600000

86400)

IN NS linux.site.com.

1 IN PTR localhost.

Since "192.11.56" is an external network segment, the configuration should include translation data from all host IP addresses to DNS host names. The configuration example is as follows:

@ IN SOA linux.site.com. Root.linux.site.com.

(199609206

28800

7200

604800

86400)

NS linux.site.com.

All hosts

24 PTR sys727.site.com.

25 PTR sys728.site.com.

26 PTR linux.site.com.

3. Get db.sitecache online.

Download named.ca from ftp.rs.internic.netr 's domain/named.root, which contains the above-mentioned Internet top-level domain name server; then copy it to the / var/named directory and rename it to db.sitecache (the file name you specified in the named.boot configuration file).

Step 3: test the named process.

1. Start named with the DNS test tool ndc that comes with Linux as mentioned earlier:

Ndc named

two。 Create a / etc/resolv.conf file, in this example:

Search site.com

Nameserver 192.11.56.26

3. Test named, command behavior:

Nslookup

If named starts normally, the address and domain name of the current DNS server will be displayed after nslookup. Otherwise, named starts abnormally. You need to re-check the previous setting steps.
