This guide will teach you how to install 4PSA DNS Manager or upgrade an existing system.

We Are Here to Help


If you need any help during installation or upgrade, do not hesitate to open a support ticket in the 4PSA Support Zone.


4PSA DNS Manager can be installed on Red Hat Enterprise Linux 4/5/6 (i386/x86_64) or CentOS 4.x/5.x/6.x (i386/x86_64).

When the OS runs on a virtualization layer, we recommend VMware Vsphere or Parallels Virtuozzo.

Check the Hardware Compatibility!


Before you start installation, make sure you review the Hardware Compatibility List (HCL).


4PSA DNS Manager can be installed in multiple ways, based on your environment and requirements. Please find below all options possible.

Supported OS Already Installed

  • No virtualization - You must install DNS Manager using the Command Line Installer;
  • Parallels Virtuozzo with root access to Virtuozzo OS - It is recommended to install DNS Manager using the Virtuozzo templates.

The Command Line Installer Is Universal


Supported OS Not Installed

You will first have to install the OS, but there are multiple paths to choose from:

  • Install a supported virtualization OS like Parallels Virtuozzo - Following the OS installation, you will be able to install DNS Manager using either the Virtuozzo templates or directly the DNS Command Line Installer;
  • Install using the ISO - You will need physical or KVM type access to the server; click here to find out how it's done;
  • Install a supported OS and then install DNS Manager using the Command Line Installer; this can be usually done with a server re-image process;

4PSA Highly Recommends Virtualization


We recommend virtualization because it brings management advantages, as well as superior resource abstraction and disaster recovery capabilities.


Plan the Upgrade

To guarantee the success of a system upgrade, it is recommended that you:

  • Review the Release Notes for the software version you want to upgrade to;
  • Check the upgrade process and the new software on a testing environment;
  • Schedule the upgrade after making sure that all implications of the upgrade are fully understood.

Highly Recommended


We highly recommend this testing phase before you start to upgrade mission critical production environments.
