This page contains instructions on the DNS Manager installation in the command line of the operating system.

Overview

Before starting the installation using the Command Line Installer, make sure that:

• The server has installed:
  • Red Hat Enterprise Linux 8
  • AlmaLinux 8
  • Rocky Linux 8
• You have reviewed the Release Notes and the minimum hardware requirements;
• You are aware of 4PSA's recommendations regarding the installation on virtualization and cloud environments.
• You are aware of the mandatory requirement to install DNS Manager on a clean server!

Installation

In order to install or upgrade to DNS Manager, you have to log in to your server as root using SSH from any client operating system, download the installer on your server by executing the command below:

curl https://repo.4psa.com/dnsmanager-installer -o /etc/yum.repos.d/voipnow.repo

The installer is compatible with Red Hat Enterprise Linux 8, AlmaLinux 8 and Rocky Linux 8. DNS Manager will not run on other Linux distributions. Install the downloaded package:

dnf -y install dnsmanager-installer

Run the installer by executing the following command:

/usr/bin/dnsmanagerinstaller

""

Wait patiently as the installer downloads all the packages from the repository, installs them, and configures the system.

Upgrade

Before preparing a system upgrade, it is highly recommended to:

• Review the Release Notes for the software version you want to upgrade to.
• Test 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.

""

We highly recommend this testing phase prior to upgrade mission critical production environments.

INFO

During a software upgrade process, your DNS server will be stopped. Consequently, it is recommended that you perform such upgrades only if redundancy is guaranteed.

To upgrade the system, you must execute the DNS Manager Installer, as described in the installation process. The upgrade might take several minutes, especially on systems with large databases. DO NOT interrupt the DNS Manager Installer by pressing CTRL-C or rebooting the system, as your upgrade might become inconsistent!
