Last Updated : Jun 10, 2026 |

About this task

Use this procedure to deploy Communication Manager ISO image in a Software-only environment.

Note:

The deployment of Avaya Aura® applications as software only is available but a restricted offer for net new deployments and requires Avaya Aura® BU approval before proceeding. If you have a business requirement to deploy Avaya Aura® as software only, please get in touch with your Avaya Sales team. Existing customers using software only deployments continue to be supported.

Before you begin

  • Create an operating system instance.

  • Ensure that you have the required hard disk space on the RHEL machine. For more information, see the Disk partitioning section.

  • Ensure that the RHEL instance should be able to communicate with a public RHEL repo or your private repo for the latest RPM updates.

  • Ensure that the Linux installation uses 'eth <x> names for the network interfaces.

  • The virtual machines must support at least 2 network interfaces for duplex configurations. On Azure 'accelerated networking' interfaces should not be enabled.

  • SSH to the RHEL virtual machine and create a root password.

  • Download the Avaya Aura® application ISO file to the virtual machine.

Procedure

  1. Switch to root user by using the following command: sudo su
  2. Create the iso directory under the mnt folder.

    For example, mkdir /mnt/iso.

  3. Run the following command to mount the ISO file: 
    mount -o loop,ro CM-010.2.0.0.*.iso /mnt/iso

    Running this command extracts all the files from the Avaya Aura® ISO zip folder.

  4. Run the following command to navigate to the iso file: 
    cd /mnt/iso
  5. To enable php 7.4 and nginx 1.20, run the following commands:
    1. yum module reset -q -y php
    2. yum module enable -y php:7.4
    3. yum module reset -q -y nginx
    4. yum module enable -y nginx:1.20
    5. yum update -y php
    6. yum update -y nginx-filesystem*
  6. Run the following command to install the dependent RPMs: 
    yum install --setopt=install_weak_deps=false -y /mnt/iso/avaya-cm-setup-010.2.*.noarch.rpm

    A message appears that the RPMs installation is complete. To check the RHEL version, run the following command: cat /etc/redhat-release.

  7. Run the ./install-cm file to start the installation.
    Note:

    When you install the Communication Manager ISO image on RHEL 8.10, the following warning message is displayed. You can ignore this warning message and proceed to the next step:
