Configure the master DNS server for DNS

Preface:If you are lucky to be seen by a friend and find something wrong in this article, you may want to criticize and correct it. If you have any questions, we hope you can discuss them together.

Because I have not registered a valid domain name, I only need to configure the DNS server in my LAN.

DNS Environment Planning

Vm ip Address: 10.170.2.10 master DNS Server

Software required to build a DNS server: bind

Set the master configuration file/etc/named. conf

# Vim/etc/named. conf

650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M01/44/B4/wKiom1PiRHiTCq_-AAHaX6gACdc114.jpg "Title =" Figure 1 "alt =" wKiom1PiRHiTCq_-AAHaX6gACdc114.jpg "/>

Configuration area configuration file/etc/named. rfc1912.zones

# Vim/etc/named. rfc1912.zones

Configure the forward solution database file/var/named/muluhe.com. Zone

# Vim/var/named/muluhe.com. Zone

Configure the reverse database file/var/named/10.170.2.zone

# Vim/var/named/10.170.2.zone

DNS startup and Testing

It's really easy to start the DNS service. You can do it with one command:

# Service named restart

To enable Automatic startup next time, run the command: # chkconfig named on

Next, we will test the above important positive and reverse information.

Positive Test

# Dig-t a www.muluhe.com @ 10.170.2.10

# Dig-T axfr muluhe.com @ 10.170.2.10

Reverse Test

# Dig-x 10.170.2.150 @ 10.170.2.10

650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/44/8C/wKioL1Ph65OA08G3AAM3ZhRXoUU137.jpg "Title =" Fig 8 "alt =" wkiol1ph65oa08g3aam3zhrxouu137.jpg "/>

# Dig-T axfr 2.170.10.in-ADDR. Arpa @ 10.170.2.10

650) This. width = 650; "src =" http://s3.51cto.com/wyfs02/M02/44/8D/wKioL1Ph66ux-iw2AARFbYc2sEs569.jpg "Title =" Fig 9 "alt =" wKioL1Ph66ux-iw2AARFbYc2sEs569.jpg "/>

Conclusion: This is only the basic configuration of the DNS server, and does not consider security issues.
