Chroot BIND DNS in Linux

Domain Name System makes our lives easy. Instead of memorizing numbers, we as the end users will only be memorizing names that are common and easy to remember.

DNS Servers provides the name resolution serves. What this mean is every time the users type a domain in their favorite web browsers this domain is automatically translated by the DNS Server in to binary wherein the computer is able to process.

In this guide we will be installing BIND DNS Server. If BIND DNS Server was installed during the installation of CentOS Linux then we are ready to configure BIND DNS Server. But if BIND ins not installed then please follow these steps.

To check if our DNS Server package is installed please do this command:

[mylogin@hostname folder]# rpm -qa | grep bind

If no information is returned then DNS package was not installed. You may use YUM for installing the DNS package.

[mylogin@hostname folder]# yum -y install bind

Notes:

yum - yellowdog update manager

• install will install the package
• -y will assume that you will answer yes to all and no prompt will return to screen .

rpm - redhat package manager

• q - Query packages
• a - All
• i - information of the package

For additional information to the commands that were used please do the following

[mylogin@hostname folder]# man yum
[mylogin@hostname folder]# man rpm
