Get Ready to Master Konfigurasi DNS Server Debian 10 with Emoji-Powered Learning!
Greetings, fellow tech enthusiasts! Are you ready to learn how to configure the DNS server on your Debian 10 system? Then you’ve come to the right place! This article will provide you with a comprehensive guide on how to configure the DNS server on Debian 10. By the end of the article, you’ll be able to configure your own DNS server like a pro! So, let’s get started!
Introduction
DNS stands for Domain Name System. DNS server resolves domain names to their respective IP addresses. It’s an essential component of the internet infrastructure that allows clients to communicate with servers and access websites. The DNS server configuration involves translating domain names to IP addresses and vice versa. The process of DNS configuration requires proper knowledge and experience.
This article will guide you through the process of configuring the DNS server on Debian 10. We’ll cover everything from installing and setting up BIND9 to creating DNS zones, configuring DNS records, and managing DNS server settings. So, let’s dive in!
1. Installing and Setting Up BIND9
The first step in configuring a DNS server on Debian 10 is to install the BIND9 package. BIND9, or named, is the most widely used DNS software on the internet. It’s free and open-source software that powers the majority of DNS servers worldwide. You can install BIND9 with the following command:
Commands |
Description |
|---|---|
sudo apt update |
Updates the package list and upgrades existing packages. |
sudo apt install bind9 dnsutils |
Installs the BIND9 package and utility tools. |
After installing BIND9, you need to configure it. The configuration files are located in the /etc/bind directory. The main configuration file is named.conf. You can edit the file using your favorite text editor. In this file, you specify the DNS server settings, such as the DNS zones, DNS records, and DNS server options.
2. Creating DNS Zones
The next step in configuring the DNS server is to create DNS zones. A DNS zone is a portion of the DNS namespace that is managed by a particular DNS server. You can create DNS zones by adding zone files to the /etc/bind folder. Each zone file contains the DNS records of a particular domain name. You can create a zone file by following these steps:
- Create a new file with a name that matches the name of the domain.
- Add the following lines to the file:
Commands |
Description |
|---|---|
$TTL 3600 |
Sets the time to live (TTL) for all records in the zone. |
@INSOAns1.example.com. admin.example.com. ( |
Specifies the start of authority (SOA) record. |
1; Serial |
Specifies the serial number of the zone file. |
3600; Refresh |
Specifies the refresh rate of the zone. |
1800; Retry |
Specifies the retry rate of the zone. |
604800; Expire |
Specifies the expiration rate of the zone. |
86400; Minimum TTL) |
Specifies the minimum TTL of the zone. |
- Add the DNS records to the file, such as A, CNAME, MX, and NS records.
- Save and close the file.
3. Configuring DNS Records
After creating the DNS zones, you need to configure the DNS records. DNS records define the mapping between domain names and IP addresses. You can add DNS records to the zone file using the following syntax:
Records |
Syntax |
Description |
|---|---|---|
A Record |
domain.com. IN A 192.168.1.100 |
Maps a domain name to an IPv4 address. |
AAAA Record |
domain.com. IN AAAA 2001:db8::1 |
Maps a domain name to an IPv6 address. |
CNAME Record |
www.domain.com. IN CNAME domain.com. |
Maps a subdomain to the parent domain. |
MX Record |
domain.com. IN MX 10 mail.domain.com. |
Specifies the mail exchange server for the domain. |
NS Record |
domain.com. IN NS ns1.domain.com. |
Specifies the authoritative name server for the domain. |
4. Managing DNS Server Settings
After configuring the DNS zones and records, you need to manage the DNS server settings. You can manage the DNS server settings using the named.conf file. The named.conf file contains global configuration options, such as the DNS server options, logging options, and security options. You can edit the file using your favorite text editor.
