Introduction
This article is showing how to install DNS Service in Linux Ubuntu 18.04. DNS Service is very useful primarily to resolve domain name so it will give the real IP Address of that domain name. The installation processes are available in this article with the following sections. Those sections are exist as follows :
1. Preparation process for the Installation of DNS Service in Linux Ubuntu 18.04
2. The Installation process of DNS Service in Linux Ubuntu 18.04
So, proceed to the following sections to read each of them in details.
Preparation Process
The following are steps taken for installing a local DNS Service in Linux Ubuntu 18.04 :
1. Make sure that the package for the Internet Domain Name Server is not exist in the operating system. In order to search whether it exist or not, just execute the command for searching installed package with the name of ‘bind’. The command execution pattern exists as follows :
dpkg -l | grep ^ii | awk {print $2} | grep pattern
Execute it by changing the pattern with the regular expression pattern of the package name. The following is the command execution :
root@hostname# dpkg -l | grep ^ii | awk '{print $2}' | grep ^bind*
binutils
binutils-common:amd64
binutils-x86-64-linux-gnu
root@hostname#
2. In the previous output, there is no package with the name of ‘bind’. Another way to make sure if there are no DNS service is running currently, just type the following command :
root@hostname# systemctl -l --type service --all | grep bind* root@hostname#
3. Since the output doesn’t show any occurrences of any services with the pattern name of ‘bind’, install the bind package. But before the installation begins, search the appropriate package name which has the function of Internet Domain Name Server resolver. Type the following command to search it :
apt-cache pkgnames | grep pattern
Using the above command pattern, execute the following command to search the Internet Domain Name Server’s package installation :
root@hostname# apt-cache pkgnames | grep ^bind.* bindgraph bind9-host bindfs bind9utils bind9-dyndb-ldap bindechexascii bind9 bind9-doc root@hostname#
4. After retrieving the list of packages where it will have high possibility of the package name, using the above command pattern, retrieve the information of the package with the name of ‘bind9’ as follows :
apt-cache show package_name
The command pattern above will show the output of the execution using ‘bind9’ as the package name for an example :

Installation Process
After checking that the package for the Internet Domain Name Server is not exist in the operating system, perform the installation. In order to execute the command for installing the selected package with the name of ‘bind’, the following is the command pattern :
apt-get -y install package_name
Execute the above command with the package name of ‘bind9’ according to the above output after searching the correct package name.
