Welcome to the ultimate guide on DNS server on Ubuntu 12.04. In today’s world, DNS is an essential part of the internet, and setting up your own DNS server can provide advantages, such as increased network performance, control over your domain names, and improved security. This step-by-step guide will walk you through the process of setting up a DNS server on Ubuntu 12.04, including all the advantages and disadvantages.
Why Ubuntu 12.04?
Ubuntu 12.04 is a long-term support (LTS) release that is still used by many organizations. It is stable and reliable, making it an excellent choice for setting up a DNS server.
The Basics of DNS
Before diving into the setup process, it is essential to understand the basics of DNS. DNS stands for Domain Name System, and it is responsible for translating human-readable domain names like www.example.com into IP addresses like 192.168.0.1 that computers can understand.
DNS operates on a hierarchical system, with the root servers at the top of the hierarchy and the authoritative servers at the bottom. When a user types a domain name into their browser, the request is sent to their ISP’s recursive resolver, which then queries the appropriate authoritative server for the IP address.
DNS works by using a combination of different record types, such as A records for IP addresses and MX records for mail servers. These records are stored in DNS zones, which are managed by authoritative servers.
Setting Up a DNS Server on Ubuntu 12.04
Step 1: Install Bind9
The first step to setting up a DNS server on Ubuntu 12.04 is to install Bind9, which is the most commonly used DNS server software. To do this, open a terminal window and enter the following command:
Command
Description
sudo apt-get update
Updates the package list
sudo apt-get install bind9
Installs Bind9
After installing Bind9, the configuration files can be found in the /etc/bind directory.
Step 2: Configure Bind9
The next step is to configure Bind9 to act as a DNS server for your domain. This involves creating a zone file and adding DNS records for your domain.
Creating a Zone File
A zone file is a plain text file that contains DNS records for a specific domain. To create a zone file, create a new file with the name of your domain, followed by the .db extension, in the /etc/bind directory. For example, if your domain is example.com, the file name should be /etc/bind/db.example.com.
Open the zone file in a text editor and enter the following:
Adding DNS Records
Once the zone file has been created, DNS records must be added for your domain. The most commonly used DNS record types are:
A – Used to map a domain name to an IP address
CNAME – Used to create an alias for a domain name
MX – Used to specify the mail servers responsible for a domain
For example, to create an A record for the domain name www.example.com, add the following line to the zone file:
www IN A 192.168.0.1
This maps the domain name www.example.com to the IP address 192.168.0.1.
Testing the DNS Server
Once the DNS records have been added, it is important to test the DNS server to ensure it is working correctly. This can be done by using the dig command in the terminal.
For example, to query the A record for www.example.com, enter the following command:
Command
Description
dig A www.example.com
Queries the A record for www.example.com
