Brief introduction of DNS master-slave server:

Primary DNS server:

The server that maintains the domain parsing library that is responsible for parsing; the parsing library is maintained by management.

From the DNS server:

Copy (zone transfer) a parse library from the main DNS server or other from the DNS server

First build the DNS server in two linux

There is a detailed tutorial in the article before the construction of DNS: https://blog.51cto.com/13630803/2114574

Let's start to configure master-slave synchronization.

1: use virtual machine 1 as the primary DNS

Edit its area file named.rfc1912.zones

Configure positive and negative parsing

Allow-transfer {192.168.100.102;; what is allowed here is the IP of the slave server

2: add DNS server IP address restart service

3: edit the slave server's zone file named.rfc1912.zones

Configure positive and negative parsing

Masters {192.168.100.101;}; specify the IP of the primary DNS server

4: join the IP from the server to the resolv.conf

Restart the service

Host 192.168.100.118 resolves the domain name as www.benet.com.

IP parsed by host www.benet.com is 192.168.100.118

5: check at / var/named/slaves

Looking at benet.com.zone and benet.com.local, you can see that the configuration file is configured for master-slave synchronization.
