Deploying and Tuning 3.3 DNS installation configuration-3

Only one DNS server is not insured, now give him a configuration from the server.

Install the configuration DNS server on another virtual machine. First look at the virtual machine IP: 192.168.1.111

Ifconfig

Give the bind and dig commands from the installation

Yum install-y bind

Yum Install-y bind-utils

To open the master configuration file

Vim/etc/named.conf

       - 127.0. 0.1 ; };      Listen :1;}; Change to //      listen-on port 127.0.0.1;}; //       listen-on-v6 port: 1;};

Comment out the default listener so the port, for a server, cannot have only one IP

Add a section at the bottom

Zone"123.com"In {type slave; File"Slaves/123.com.zone"; Masters {192.168.1.117; };}; Zone"1.168.192.in-addr.arpa"In {type slave; File"Slaves/1.168.192.zone"; Masters {192.168.1.117; };};

Start the DNS server

/etc/init.d/named start

See if there are any generated files

LS/var/named/slaves/

1.168.192.zone 123.com.zone

Test parsing

Dig @192.168. 1.111 www. 123. com

Parse success

Open the configuration file above the main, add a domain name

Vim/var/named/123. Com.zone

2015122601       ; serial changed to 2015122602      ; serial add one row to the bottom Denny in      A       111.111 . 111.111

Restart

/etc/init.d/named restart

Test Master

Dig @192.168. 1.117 Denny. 123 . com parsing succeeded

Test from

Dig @192.168. 1.111 Denny. 123 . com parsing failed because there is a time interval to check that the serial number has not changed. 

In order to update from the synchronization, open the master's main configuration file

Vim/etc/named.conf

Zone"123.com"In {type master; File"123.com.zone";}; Zone"1.168.192.in-addr.arpa"In {type master; File"1.168.192.zone";}; Change to Zone"123.com"In {type master; File"123.com.zone";        Notify yes; Also-notify {192.168.1.111; };}; Zone"1.168.192.in-addr.arpa"In {type master; File"1.168.192.zone";        Notify yes; Also-notify {192.168.1.111; };};

Restart

/etc/init.d/named restart

Test from

Dig @192.168. 1.111 Denny. 123 . com parsing succeeded

See the 123.com.zone from

CAT/var/named/slaves/123. Com.zone

The added Denny 111.111.111.111 has been updated.
