Installing the Red Hat Enterprise Linux software for AE Services

Last Updated : Sep 27, 2024 |

Before you begin

  • You must install the Red Hat Enterprise Linux (RHEL) before you install the AE Services software because the AE Services installation script also configures RHEL for AE Services.

    Note:

    Avaya does not provide RHEL installation media with the AE Services Software-Only offer. This document assumes that you have obtained Linux® Operating System RHEL 8.4 or RHEL 8.10 (64-bit) with all security updates applied.

    Refer to the RHEL Installation Guide when you install RHEL. The following steps provide a high-level summary of the installation with a few specific instructions for installing AE Services.

  • Perform the installation using the graphical user interface (GUI) installation program. In general, you can use the default options. However, when you install the Software Packages, Avaya recommends that you customize the software selection instead of installing the default packages, as described in this procedure.

Procedure

  1. Boot to your RHEL installation media. Follow the instructions of the installation utility.
  2. In the RHEL installation program, follow these steps to set up a /var partition.
    Note:

    Although you can use the RHEL default partitioning, Avaya recommends that you set up the /var directory as a file system (partition) to improve system reliability. This change prevents the AE Services root directory from becoming filled with log messages.

    1. On the Disk Partition Setup screen, select the partition method you prefer, such as Automatically partition.
    2. On the next screen, click New.
    3. Name the partition /var and complete the screen.
    4. Allocate about 40 percent of the disk drive space to create the /var partition if available.

      • The /var partition must be at least 9.5 GiB in size.

      • On the Firewall Configuration screen, the Security Enhanced Linux (SELinux) features are active by default. You must disable SELinux or AE Services will not work correctly.

      • Avaya recommends separating /var/log/ partition to avoid system instability in case the partition fills up due to large log files.

      • The /var/log/ partition must be at least 18.5 GiB in size.

  3. On the Software Selection page, in the Base Environment and Add-Ons for Selected Environment sections, keep the default selections.

    In the Base Environment section, the Minimal Install option is selected by default and in the Add-Ons for Selected Environment section, all the options are cleared by default.

  4. Complete the RHEL installation and reboot the server.

    The time required for the software installation depends on the options you selected and the server processing power. Allow several minutes.

    Note:

    See Configuring Linux OS before installing AE Services Software-Only offer.

  5. For security purposes, enable only the specific ports you require.

    Include all the ports that the AE Services software uses. For a list of required ports, see the Port Matrix for Avaya Aura® Application Enablement Services 10.2 and Whitepaper on Security in Avaya Aura® Application Enablement Services. The Port Matrix and Whitepaper are available with the AE Services customer documents on the Avaya Support website at http://www.avaya.com/support.
