HAProxy ALOHA Documentation 14.0

Firmware Updates

In this section, you will learn how to check which version of the firmware you currently have and how to download and install a newer version.

Check your current firmware version

To obtain the current version of the firmware that you have installed:

  1. In the web user interface, go to the Setup tab.

  2. Find the firmware version number in the System section, where it is labelled Version.

    https://cdn.haproxy.com/documentation/aloha/latest/assets/aloha-firmware-version-c53901ab5be5b3686d2c1c065ed8b0f6d79524956a6677aff2dcc3b8f5ab5bb8.png

Alternatively:

  1. Log in to the HAProxy ALOHA command-line interface.

  2. Read the file /usr/share/factory/version to see the Version.

    $ cat /usr/share/factory/version

Install the latest firmware

Follow these steps to install the latest version of the firmware.

  1. Obtain your credentials for accessing HAProxy ALOHA downloads. You can create a new support ticket in the HAProxy Technologies Customer Portal to request your credentials.

  2. Browse to the website https://www.haproxy.com/download/aloha/14.0. Enter your credentials to access the folder.

  3. Go into the folder with the highest number. (e.g. 13.0.5)

  4. Download the file for your appliance model.

    • For the virtual appliance, the file is prefixed with albva (e.g. albva-13.0.5-1312.bin).

    • For the hardware appliance, the file is prefixed with the hardware model (e.g. alb5200-13.0.5-1312.bin for the ALB5200 model).

  5. If you run two HAProxy ALOHA instances in active-standby mode, then update the standby instance first:

    • On the active instance, ensure that your current load balancer configuration has been synced to the standby instance. Then save the configuration by going to the Setup tab and clicking Save in the Configuration section.

    • On the standby instance, go to the Setup tab and in the Firmware section click Browse to upload the .bin file.

    • Click Update and then Reboot.

    • If everything looks normal, promote the standby instance to be the primary, active instance by increasing its VRRP weight.

      • From the Services tab, click the setup_icon Setup icon on the network service line.

      • Update the vrrp prio number to be greater than the current primary instance's value.

      • The standby becomes the new primary and handles the traffic.

      • We recommend monitoring HAProxy ALOHA until you are confident that it is functioning correctly.

        You can still swap the active and standby back by lowering the instance's vrrp prio number to its original value. You can also revert by following the steps in the Roll back section below.

  6. Update the other HAProxy ALOHA instance.

    • Go to the Setup tab and, in the Firmware section, click Browse to upload the .bin file.

    • Click Update and then Reboot.

    • If you are running two HAProxy ALOHA instances, you can change the original standby node to be on standby again. On the standby instance, go to the Services tab, click the setup_icon Setup icon on the network service line. Lower the vrrp prio number to the value before the upgrade.

At this stage, your HAProxy ALOHA instances have been updated to the new firmware. During this update, the load balancer configuration may have been migrated to use new keywords if older keywords were obsoleted. If you go to the Setup tab and click Save in the Configuration section, then the new configuration is made permanent. You can still roll back to the previous firmware, but the configuration will not be reverted. In rare cases, the new configuration may be incompatible with the older firmware.

Update additional modules

If you previously installed any additional modules, then you should update them too to be compatible with version 14.0 of the firmware. Module updates may also contain new features and bug fixes.

Follow these links to find instructions for updating each of the modules:

Module

Data Plane API

Web Application Firewall

Roll back an update

By default, HAProxy ALOHA stores two firmware images:

  • the current running firmware

  • the firmware that was running before the last upgrade

Follow these steps to revert to the firmware that was running before the last upgrade:

  1. On the Setup tab, and scroll down to the Firmware area.

  2. Look at the Next boot image radio buttons. The box checked indicates the currently running firmware.

  3. Check the other box pointing to the old image.

  4. Click Update and then Reboot.
