Step G: Upgrade worker nodes - AWS Elemental Conductor Live

Step G: Upgrade worker nodes

Perform these steps on the AWS Elemental Live nodes.

There are two procedures for upgrading the worker nodes. Choose the procedure that applies to your deployment. There is just one procedure for upgrading the Conductor Live nodes.

To upgrade worker nodes without changing the deployment

Follow this procedure if you don't need to change anything about the deployment.

  1. From the Linux command line, log in to the worker node. Use the elemental user credentials.

  2. Run the installer. Make sure to include the -c option to clear the database. Use the appropriate command:

    • For GPU and CPU versions of the software:

      [elemental@hostname ~]$ sudo sh ./elemental_production_live_2.25.5.12345.run -c --skip-all --start -xeula

    • For CPU-only versions of the software:

      [elemental@hostname ~]$ sudo sh ./elemental_production_live_cpu_2.25.5.12345.run -c --skip-all --start -xeula

  3. If you copied a script to a safe location (as described in Move custom files), copy it back to its location in /opt/elemental_se/scripts.

  4. When the upgrade is complete, restart the node with the following command:

    [elemental@hostname ~] sudo reboot

  5. Repeat the upgrade steps on each worker node before moving on to the next step in the upgrade process.

To upgrade backup worker nodes and change the deployment

Follow this procedure if you want to change something in the deployment. Specifically, follow this procedure if you want to enable OCR conversion for the first time. This feature is available in AWS Elemental Live version 2.22.0 and later. (For information about this feature, see Support for OCR Conversion in the AWS Elemental Live User Guide.)

  1. Follow the appropriate procedure in the AWS Elemental Live Installation Guide:

  2. If you copied a script to a safe location (as described in Move custom files), copy it back to its location in /opt/elemental_se/scripts.

  3. When the upgrade is complete, restart the node with the following command:

    [elemental@hostname ~] sudo reboot

  4. Repeat the upgrade steps on each worker node before moving on to the next step in the upgrade process.

To upgrade the Conductor Live nodes

Perform these steps on the secondary Conductor Live (if applicable), then on the primary Conductor Live.

  1. From the Linux command line, log in to the Conductor node. Use the elemental user credentials.

  2. Run the installer:

    • For the secondary Conductor Live, make sure to include the -c option to clear the database. Use this command:

      [elemental@hostname ~]$ sudo sh ./elemental_production_conductor_live247_3.25.5.12345.run -c --skip-all --start -xeula

    • For the primary (or only) Conductor Live, do not include the -c option to clear the database. Use this command:

      [elemental@hostname ~]$ sudo sh ./elemental_production_conductor_live247_3.25.5.12345.run --skip-all --start -xeula

    The installer automatically stops the software. You will not be prompted to do the following:

    • Change the network setup (eth0 and eth1) or the Ethernet partitioning (setup of eth0 as a management interface).

    • Choose the timezone.

    • Enable or disable user authentication.

  3. Make sure that the elemental_se service restarts. Look for this prompt on the primary Conductor Live command line:

    Starting elemental_se:            [OK]

  4. If you copied a script to a safe location (as described in Move custom files), copy it back to its location in /opt/elemental_se/scripts
