Installing the Red Hat Enterprise Linux (RHEL) software for AE Services

About this task

noteNote

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

Avaya does not provide RHEL installation media with the AE Services Software-Only offer. This document assumes that you have obtained Linux® Operating System 7, Update 4 (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.

noteNote

Perform the installation using the graphical user interface (GUI) installation program. In general, you can use the default options. However, when you are installing the Software Packages, Avaya strongly 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.
    noteNote

    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 10 GB 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.

  3. From the Linux Package Installation Defaults screen, select Customize Now (do not install the default package set).
    noteNote

    For the Software Package selection, Avaya strongly recommends that you customize the packages for your system.

  4. From the Linux Package Group Details screen, disable the selection of all other components in the right pane from every group (in the left pane).

    Only enable Base System (in the left pane) and leave the right pane with the default options.

  5. 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.

    noteNote

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

  6. 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 White Paper on Security in Application Enablement Services for Software Only Solution. This white paper is available with the AE Services customer documents on the Avaya Support Web site: http://www.avaya.com.
