The Linux system establishes the DNS master-slave name server to implement forward reverse query

Experimental Requirements: Establish DNS the principal and subordinate domain name server implements forward reverse query

Experimental steps:

1. forward Query

Mount and install first Bind Software

if rpm install dependencies, then use yum warehouse installation, first look at yum yum vi editor configuration file ( abc is the file name, name baseurl is a package-mounted path, enabled gpgcheck means not to check the software serial number)

Note: Yum The warehouse is well built and can be inspected ( Yum list)
