Got root? Then you have your freedom to do whatever you want with your slice of node. People moved from shared or reseller hosting to vps because they want to experiment more with their (in this case) website. Probably tried another web server such as Cherokee, Engine-X, Lighttpd, or Litespeed. For database, they want to experience other than MySQL, like MariaDB (the MySQL development-based database), PostgreSQL, or NoSQL. The rest, of course PHP (we are talking about linux OS), no way in the 21st century you still run your dynamic website with HTML only.
Everything is set up, and you go check your domain whois, your domain nameserver appeared as ns1.anotherdomainnotyourdomainhere.com. You still use 3rd party DNS, usually your domain registrar’s DNS or DNS that many people use such as afraid, he.net, etc.. For
me small business site like company profile, merchandise, or store, it will be good to use own domain as your nameserver. As the title says, low memory vps for people who have just started small business, so the NSD low memory DNS is suitable for it.
For this, i am using 128MB KVM with Debian 6 OS, it is quite low in memory consumption. I assume you have installed your preferred low memory webserver, database, and php, so i just headed to NSD installation.
apt-get install nsd3
Just like that, you have installed NSD DNS in your box, simple eh? Now continue with the configuration. Go to “/etc/nsd3” directory and create NSD server configuration. Below are the essential configurations i took from NSD’s default configuration.
# nsd.conf -- the NSD(8) configuration file, nsd.conf(5).
# Copyright (c) 2001-2006, NLnet Labs. All rights reserved.
# See LICENSE for the license.
# This is a comment.
# Sample configuration file
# options for the nsd server
# uncomment to specify specific interfaces to bind (default all).
# don't answer VERSION.BIND and VERSION.SERVER CHAOS class queries
# listen only on IPv4 connections
# the database to use
# identify the server (CH TXT ID.SERVER entry).
# Number of NSD servers to fork.
# File to store pid for nsd in.
# port to answer queries on. default is 53.
# The directory for zonefile: files.
# key for zone 1
# Sample zone 1
Change the configurations needed and save as nsd.conf, and now we create Zone Configuration, here for the example i have domain “your_domain_here.com” and want to create “ns1.your_domain_here.com” and “ns2.your_domain_here.com” for name server.
your_domain_here.com. IN SOA ns1.your_domain_here.com. firstname.lastname@example.org. (
1 ; serial number
28800 ; refresh
7200 ; retry
604800 ; expire
3600 ; min ttl
your_domain_here.com. IN A your_vps_ip_address_here
ns1.your_domain_here.com. IN A your_vps_ip_address_here
ns2.your_domain_here.com. IN A your_vps_ip_address_here
your_domain_here.com. IN NS ns1.your_domain_here.com
your_domain_here.com. IN NS ns2.your_domain_here.com
The first is SOA (Start Of Authority), contains as the first line until the closing parenthesis, you can edit it base on your data and needs. The second until the fourth line i am pointing the domain and nameserver to our
static vps ip address as A Record. And for the last two, we declare your_domain_here.com to use ns1 & ns2 dot your_domain_here.com.
So the configurations are set, now we rebuild the NSD database, reload it, and start.
Easy right? Yeah it is. Don’t forget to register your nameserver and set your domain nameserver in your domain control panel, and
you are your website is ready to go!
