Update HAProxy Enterprise to the latest build

The update procedure installs the latest build for your current HAProxy Enterprise version in order to benefit from the newest bug fixes.

  • Run the following command:

    yum update

Upgrade to HAProxy Enterprise 1.8r2 from a previous version

The following upgrade procedure installs a new major version of HAProxy Enterprise.

  1. Take the server that you want to upgrade out of the cluster.

  2. Install HAProxy Enterprise 1.8r2 by running the following command and replacing <HAProxy Enterprise Key> with the key you received when you registered:

    curl -s https://cdn.haproxy.com/static/install_haproxy_enterprise.sh | sudo bash /dev/stdin 1.8r2 <HAProxy Enterprise key>
  3. Update additional modules: you may be running additional modules with HAProxy Enterprise, which you must also reinstall when you upgrade to a new release. Install a package using its name, for example:

  4. Copy /etc/hapee-[previousversion]/hapee-lb.cfg over to /etc/hapee-1.8/hapee-lb.cfg and any associated files (maps/certificates/etc).

  5. Disable the old HAProxy Enterprise version from starting with the system, as follows:

    systemctl disable hapee-<previousversion>-lb
  6. Ensure that the new HAProxy Enterprise version starts with the system, as follows:

    systemctl enable hapee-1.8-lb
  7. Stop the old HAProxy Enterprise daemon and start the new daemon:

    systemctl hapee-<previousversion>-lb stop
    systemctl hapee-1.8-lb start

    On older systems that do not have systemctl, use:

    sudo service hapee-1.8-lb start
  8. Run tail -f /var/log/syslog (or distribution equivalent) to check for warnings or errors.

  9. Run wget localhost to ensure that HAProxy is responding. Adjust address/port as needed, and use a local address that is currently active on the box and not a VRRP IP.

  10. Put the upgraded server back into the cluster.

  11. Repeat this procedure on secondary servers.

Upgrade to HAProxy Enterprise 1.8r2 from 1.8r1

When upgrading HAProxy Enterprise 1.8r1 to 1.8r2, the following conditions apply:

  • The directory names do not change.

  • The configuration files are located in the same place.

  • The init scripts keep the same names.

  • Each release of a version is mutually exclusive, which means that another release of an HAProxy Enterprise version cannot run together on the same server.

  • HAProxy Enterprise repositories, GPG key, and customer subscription key remain the same.

  1. Take the server that you want to upgrade out of the cluster.

  2. Run the following command to install the new release:

    curl -s https://cdn.haproxy.com/static/install_haproxy_enterprise.sh | sudo bash /dev/stdin 1.8r2 <HAProxy Enterprise key>
  3. Restart the service:

    systemctl hapee-1.8-lb start

    On older systems that do not have systemctl, use:

    sudo service hapee-1.8-lb start
  4. Run tail -f /var/log/syslog (or distribution equivalent) to check for warnings or errors.

  5. Run wget localhost to ensure that HAProxy is responding. Adjust address/port as needed, and use a local address that is currently active on the box and not a VRRP IP.

  6. Put the upgraded server back into the cluster.

  7. Repeat this procedure on secondary servers.

    Note

    Release upgrades do not require an uninstallation of the previous version.

Post-upgrade

  • For the additional modules, see their corresponding documentations for instructions on how to enable and configure each package.
