mv poweradmin-2.1.7/ /var/www/html/poweradmin

Note: If you use Ubuntu version lower than 14.04 such as Ubuntu 13.10, 13.04, 12.04 etc., then the apache root document folder will be /var/www/.

Set the proper permission and ownership to /var/www/html/poweradmin directory.

On RPM based systems:

chown -R apache:apache /var/www/html/poweradmin/

On DEB based systems:

sudo chown -R www-data:www-data /var/www/html/poweradmin/

Finally, restart apache service to take effect the changes.

service httpd restart

On DEB based systems:

sudo service apache2 start

Starting Poweradmin Web-based installer:

Once you completed all the above steps, open up your web browser, and type http://ip-address/poweradmin/install/ to start the web-based installation.

On RPM based systems, you might be end up with: “403 forbidden” error.

403 Forbidden - Mozilla Firefox_001

To fix this error, setup the proper SELinux policies using commands:

setsebool -P httpd_enable_homedirs true
chcon -R -t httpd_sys_content_t /var/www/html/poweradmin/

After running the above commands, refresh your web page. You should see the following screen. Select your preferred language and Click Go to step 2 button.

Poweradmin - Mozilla Firefox_002

Now you should get warning message like:

“This installer expects you to have a PowerDNS database accessable from this server. This installer also expects you to have never ran Poweradmin before, or that you want to overwrite the Poweradmin part of the database. If you have had Poweradmin running before, any data in the following tables will be destroyed: perm_items, perm_templ, perm_templ_items, users and zones. This installer will, of course, not touch the data in the PowerDNS tables of the database. However, it is recommended that you create a backup of your database before proceeding.”

That means, if you have any zone files created in your PowerDNS server, plas backup them first.

Click the Go to step 3 button.

Poweradmin - Mozilla Firefox_003

This is the important step. Keep attention. Enter the database username and password to connect to the database. As you may know, we have created the database for PowerDNS with proper permission during PowerDNS installation in our previous articles. Also, select your database type(Ex.MySQL, PostgreSQL etc). Enter the name of the PowerDNS database and the password of the Poweradmin administrator. This administrator has full rights to Poweradmin using the web interface.

Then, click Go to step 4 button.

Poweradmin - Mozilla Firefox_005

Here,

powerdns (You can also use ‘root’ in the Username section) – The username to use to connect to the database, make sure the username has sufficient rights to perform administrative task to the PowerDNS database (the installer wants to drop, create and fill tables to the database). MySQL – The type of the PowerDNS database. localhost – The hostname on which the PowerDNS database resides. Frequently, this will be “localhost”. 3306 – The port the database server is listening on. powerdns – The name of the PowerDNS database. If you have entered the correct values, you should see the following screen. Otherwise, make sure you have entered the correct database name, user name and password details.

Now, enter the username and password for Poweradmin. This new user will have limited rights only. Click Go to step 5 button to continue.

Poweradmin - Mozilla Firefox_006

Here,

poweruser – The username for Poweradmin. centos – The password for this username. hostmaster.unixmen.local – When creating SOA records and no hostmaster is provided, this value here will be used. Should be in the form “hostmaster.example.net”. ns1.unixmen.local – When creating new zones using the template, this value will be used as primary nameserver. Should be like “ns1.example.net”. ns2.unixmen.local – When creating new zones using the template, this value will be used as secondary nameserver. Should be like “ns2.example.net”. Click Go to step 6 to update records in the PowerDNS database.

Poweradmin - Mozilla Firefox_007

Now, the installer will ask you should now create the file “../inc/config.inc.php” in the Poweradmin root directory yourself. And update the contents of the config.inc.php file with the contents as shown in the below screen.

Poweradmin - Mozilla Firefox_008

To do that, open terminal and create config.inc.php file in the Poweradmin root directory,

vi /var/www/html/poweradmin/inc/config.inc.php

Add the following lines as shown in the above screenshot.

<?php

$db_host		= 'localhost';
$db_user		= 'poweruser';
$db_pass		= 'centos';
$db_name		= 'powerdns';
$db_type		= 'mysql';
$db_layer		= 'PDO';

$session_key		= 'pgSB2Dr(M5_@9LWdRq~tNHQGL%VL#xf+24BO[(y{*XGf89';

$iface_lang		= 'en_EN';

$dns_hostmaster		= 'hostmaster.unixmen.local';
$dns_ns1		= 'ns1.unixmen.local';
$dns_ns2		= 'ns2.unixmen.local';

After creating the config.inc.php file, return back to your installation screen and click Go to step 7 button.

Done! Now we have finished the configuration.

Poweradmin - Mozilla Firefox_010

If you want support for the URLs used by other dynamic DNS providers, run “cp install/htaccess.dist .htaccess” and enable mod_rewrite in Apache.

You must remove the directory “install/” from the Poweradmin root directory. You will not be able to use Poweradmin if it exists.

rm -fr /var/www/html/poweradmin/install/ After you have removed the directory, you can login to Poweradmin web console using URL http://IP-address/poweradmin/index.php with username “admin” and password “centos”(which we created in the previous steps).

Poweradmin - Mozilla Firefox_011

This is how my Poweradmin Dashboard looked after entering into it.

Poweradmin - Mozilla Firefox_012

It is highly recommended to change and set a strong password for Poweradmin user.

To do that, click on the Change password link in the Dashboard.

Poweradmin - Mozilla Firefox_012

Enter the current and new passwords twice.

Poweradmin - Mozilla Firefox_014

Now, our Poweradmin web console has been secured.
