DNS configuration for Linux 2-master-Slave server

1. Experimental background

Prior to the Linux DNS configuration 1-dns get started, where only one DNS server, but generally in large networks, through the configuration of the secondary DNS server can improve the reliability of the DNS service

2. Experimental requirements

In the LAN Vmnet2, configure two DNS servers, IP is 192.168.0.254 as the primary Domain name Server (master), IP is 192.168.0.253 as the secondary name server (Slave), manually change the configuration information in master to see if Slave changes

3. Experimental topology

4. Experimental steps

(1) Build network, so that master and slave can ping each other

(2) on the 192.168.0.254:

1) Install the DNS server (mount the disc first, configure the local Yum source)

1 [[email protected] yum.repos.d]# Yum install bind-y

2) Configuring the master configuration file
