1

Ensure that virtual machines that you plan to use to deploy Avaya Aura® Web Gateway comply with the requirements for software-only installation.

See the requirements in Software requirements and Resource profile specifications for Avaya Aura Web Gateway on VMware.

2

Download the Avaya Aura® Web Gateway software-only installation package from PLDS.

The software-only installation package includes the following files:

• Software-only system layer installer.

• Avaya Aura® Web Gateway application installer.

The package file name has the csa-swonly-<AAWG_VERSION>.tgz format.

3

Install Red Hat Enterprise Linux (RHEL) 8.10.

Avaya Aura® Web Gateway Release 10.2.x requires RHEL 8.10. For more information about installation, see the official Red hat documentation. Avaya also recommends that you install the latest security updates on RHEL.

4

Create disk partitioning on RHEL.

Avaya Aura® Web Gateway requires specific disk partitioning to organize data storage. For more information about creating disk partitioning, see Creating disk partitioning for software-only deployments and Disk partitions for software-only deployments.

5

Create a non-root Linux user.

The installation and administration of the Avaya Aura® Web Gateway server is more secure when performed by non-root users with sudo privileges. For more information, see Creating an administrative user.

6

Enable the YUM package manager on RHEL.

The YUM package manager is used to install the required packages. For more information about enabling YUM, see the Red Hat YUM documentation.

7

Install additional packages required by Avaya Aura® Web Gateway.

By default, RHEL 8.10 does not contain certain packages that Avaya Aura® Web Gateway requires. You must install these packages manually. For more information, see Additional packages required by Avaya Aura Web Gateway and Installing additional RHEL 8.4 or RHEL 8.10 packages manually.

8

Enable the Haveged service.

See Enabling the Haveged service.

9

Optional: Enable FIPS mode.

For software-only deployments, you can only enable FIPS mode before installing the system layer. For more information about enabling FIPS, see Enabling FIPS for software-only systems.

10

For more information, see RHEL packages management.

Registering your RHEL instance to the Red Hat subscription is the preferred option.

11

Install the software-only system layer on your RHEL.

The system layer is low-level software that forms the required operational environment for Avaya Aura® Web Gateway.

For more information, see Installing the system layer.

12

Ensure that:

• Chrony service is up and running.

• System Manager is reachable from your virtual machine.

Perform these checks to ensure that the system layer is installed successfully so you can install the Avaya Aura® Web Gateway application.

For more information, see Checking the Chrony service status and Checking the connection to System Manager.

13

Optional: Configure UEFI Secure Boot settings.

For security reasons, Avaya Aura® Web Gateway uses the UEFI Secure Boot feature by default. If required, you can configure the Secure Boot settings as described in Configuring UEFI Secure Boot for OVA-based virtual machines.
