Install DNS Server with fmDNS Graphical Interface on CentOS/RHEL 6.x/7.x

Posted on by Md Mahedi Hasan

Description

Manage one or more ISC BIND DNS servers without having to login to each server to update zone or configuration files. Just make your changes and build the configs all from the web interface. With fmDNS, you can manage:

  • Zone files (A, AAAA, CNAME, PTR, TXT, SRV, NS records, and many more!)
  • named options
  • Views
  • ACLs
  • Keys
  • Logging channels and categories
  • Controls
  • DNSSEC keys and zones

Settings can be configured globally for all servers with individual server overrides for when your servers are all configured the same and when they are all unique. You can also import existing named-compatible zone files for faster data entry.

Server configuration and zone files can be updated via cron, http(s), or ssh.

DNS Server Details:

Hostname         : dns.mahedi.me
IP Address       : 192.168.0.14/24

1. Hostname Configuration

Edit /etc/sysconfig/network file to configure hostname:

vim /etc/sysconfig/network

and set such as:

NETWORKING=yes
HOSTNAME=dns.mahedi.me

For RHEL/CentOS-7 Edit /etc/hostname :

vim /etc/hostname

and set such as:

dns.mahedi.me

Edit the /etc/hosts file:

vim /etc/hosts

and set such as:

127.0.0.1       localhost.localdomain   localhost
192.168.0.14    dns.mahedi.me           dns

Check hostname with the following command and see the output:

[[email protected] ~]# hostname 
dns.mahedi.me

[[email protected] ~]# hostname -f 
dns.mahedi.me

[[email protected] ~]# hostname -d
mahedi.me

Welcome to the fmDNS installer.

Please answer the following questions and the necessary configurations will be
performed for you.

Please enter the location of the facileManager interface:
 Examples include:
 fm.mydomain.com
 fm.mydomain.com:8443
 mydomain.com/fm
 http://fm.mydomain.com/facileManager

Please enter the location of the facileManager interface:

Now give your web-UI access URL: http://192.168.0.14/dnsadmin/

 
Please enter the location of the facileManager interface: http://192.168.0.14/dnsadmin/
  --> Testing 192.168.0.14 via https...failed
  --> Testing 192.168.0.14 via http...ok
  --> Checking account details...Success

Just press enter or give a serial number for zone update:

Please enter the serial number for dns.mahedi.me (or leave blank to create new):

  --> Generating new serial number: 562003234
  --> Adding dns.mahedi.me to the database...Success
  --> Running version tests...ok

  --> Tests complete.  Continuing installation.

Select the update method how server gets the update from web UI (available methods are cron, ssh, or http(s) [c|s|h]) give “c” for cron its work fine for me.

Will dns.mahedi.me get updates via cron, ssh, or http(s) [c|s|h]? c
  --> The crontab has been created.

Configuration file has been saved.

Installation is complete. Please login to the UI to ensure the server settings
are correct.

It’s seen fine. Let’s Add server in UI:

Click Enable button to enable server:


Then click Build configuration to initialize  the server:

It’s done. Your UI interface ready communicate with your server and configure your domain in web UI and automatically update in your server.

!Note: Any changed in configuration file in your server will be modified in every 5 minute from the configuration of database. So for every update and modification done in web interface not in configuration files stored in server.

Zone Creation:

At first, we need to create SOA template that would help you instead of put SOA information every time for every zone.

Create the zone for your domain:

 

Check configuration:

Edit /etc/resolve.conf file and set your server address in Linux client machine:

search mahedi.me
nameserver 192.168.0.14

Now check with different tools. Most famous DNS check tools are nslookup and dig. nslookup is preinstalled in windows and Linux.

[[email protected] ~]# nslookup 
> mahedi.me
Server:		192.168.0.14
Address:	192.168.0.14#53

Name:	mahedi.me
Address: 192.168.0.14
> set type=any
> mahedi.me
Server:		192.168.0.14
Address:	192.168.0.14#53

mahedi.me
	origin = dns.mahedi.me
	mail addr = admin.mahedi.me
	serial = 2016061903
	refresh = 7200
	retry = 3600
	expire = 1209600
	minimum = 86400
mahedi.me	nameserver = dns.mahedi.me.
mahedi.me	mail exchanger = 10 dns.mahedi.me.
Name:	mahedi.me
Address: 192.168.0.14
> 192.168.0.14
Server:		192.168.0.14
Address:	192.168.0.14#53

14.0.168.192.in-addr.arpa	name = dns.mahedi.me.

Check configuration with dig tools:

[[email protected] ~]# dig  mahedi.me +all
