Start and enable mysql service

[root@linuxhelp1 ~]# systemctl enable mariadb.service
ln -s ' /usr/lib/systemd/system/mariadb.service'  ' /etc/systemd/system/multi-user.target.wants/mariadb.service' 
[root@linuxhelp1 ~]# systemctl start mariadb.service

Setup a password for MariaDB by running the following command.

[root@linuxhelp1 ~]# mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we' ll need the current
password for the root user. If you' ve just installed MariaDB, and
you haven' t set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none):
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password:
Re-enter new password:
Password updated successfully!
Reloading privilege tables..
... Success!

By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
... Success!

Normally, root should only be allowed to connect from ' localhost' . This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] n
... skipping.

By default, MariaDB comes with a database named ' test'  that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
- Dropping test database...
... Success!
- Removing privileges on test database...
... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
... Success!

Cleaning up...

All done! If you' ve completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

After configuring MariaDB, install the PowerDNS

Open the powerdns configuration file.

[root@linuxhelp1 ~]# vim /etc/pdns/pdns.conf

Add the following lines into it.

Enable launch=gmysql

gmysql-host=localhost
gmysql-user=powerdns
gmysql-password=linuxc
gmysql-dbname=powerdns

Start and enable the pdns.service

[root@linuxhelp1 ~]# systemctl start pdns.service
[root@linuxhelp1 ~]# systemctl enable pdns.service
ln -s ' /usr/lib/systemd/system/pdns.service'  ' /etc/systemd/system/multi-user.target.wants/pdns.service' 

Install the dependency packages before installing Power admin.

[root@linuxhelp1 ~]# systemctl enable httpd.service
ln -s ' /usr/lib/systemd/system/httpd.service'  ' /etc/systemd/system/multi-user.target.wants/httpd.service' 

Now download the Poweradmin package from the location /var/www/html/

[root@linuxhelp1 ~]# cd /var/www/html/

Open the browser and enter http://192.168.7.235/poweradmin-2.1.7/install/, Choose the language for your Poweradmin and click " Go to step 2" button.

Click " Go to step 3 " to proceed further.

Enter the database credentials as setup earlier and click " Go to step 4" .

Create a new user with a limited rights for Poweradmin.

Now you have to set limited power to admin by executing the code provided by Poweradmin in the terminal.

[root@linuxhelp1 html]# mysql -u root -p

Then navigate to the browser and click on " Go to step 6" . Open the terminal and rename the config file as " ./inc/config.inc.php" and add the following lines as follows. Finally click " Go to step 7"

[root@linuxhelp1 html]# cd poweradmin-2.1.7/inc/
[root@linuxhelp1 inc]# ls

$session_key = ' 2Y~R{^Wo!zHh%N%Lxk)qX3^%hphVSb9^Q]7m-@J8FJba-('  
$dns_hostmaster = ' linuxhelp1'  
$dns_ns1 = ' ns1.localhost.com'  
$dns_ns2 = ' ns2.localhost.com'  

Now we have configured the Poweradmin

Run the following command to support the URL' s used by the other dynamic DNS provider.

[root@linuxhelp1 poweradmin-2.1.7]# cp install/htaccess.dist .htaccess

Then enable mod_rewrite in Apache’ s configuration.

Remove the " install" folder from Poweradmin’ s root directory.

[root@linuxhelp1 poweradmin-2.1.7]# rm -rf /var/www/html/poweradmin-2.1.7/install/

Now open the browser and type http://192.168.7.235/poweradmin-2.1.7/ to access poweradmin.

To add new master zone, simply click on the “ Add master zone” :

Click “ Add zone” button to add the DNS zone.

Choose " List zones" to list the available zones.

To edit or add new records, click the edit icon.

On the next page you will see the entries for the DNS zone.

Add new DNS zone and set the following information.

Finally click “ Add record ” button.
