Installation Jump to heading

The following procedure adds package repositories and installs HAProxy Enterprise 3.0r1.

  1. Download the installer:

    nix
    wget https://www.haproxy.com/static/install_haproxy_enterprise.sh
    nix
    wget https://www.haproxy.com/static/install_haproxy_enterprise.sh
  2. Optional: To verify the integrity of the install script before installing, download the SHA hash to a local directory and use it to verify the install script’s checksum:

    nix
    wget https://www.haproxy.com/static/install_haproxy_enterprise.sh.sha512.asc
    gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xCA2DF14657C5A207
    gpg --verify ./install_haproxy_enterprise.sh.sha512.asc
    nix
    wget https://www.haproxy.com/static/install_haproxy_enterprise.sh.sha512.asc
    gpg --keyserver hkp://keyserver.ubuntu.com --recv-keys 0xCA2DF14657C5A207
    gpg --verify ./install_haproxy_enterprise.sh.sha512.asc

    Check for the output Good signature.

  3. To install HAProxy Enterprise, run the following command, replacing <HAProxy Enterprise Key> with the key you were given when you registered (see HAProxy Enterprise license key). Register for a trial.

    nix
    sudo bash ./install_haproxy_enterprise.sh --version "3.0r1" --key "<HAProxy Enterprise key>"
    nix
    sudo bash ./install_haproxy_enterprise.sh --version "3.0r1" --key "<HAProxy Enterprise key>"

    To see other arguments, run ./install_haproxy_enterprise.sh --help.

  4. Enable and start the HAProxy Enterprise service:

    nix
    sudo systemctl enable hapee-3.0-lb
    sudo systemctl start hapee-3.0-lb
    nix
    sudo systemctl enable hapee-3.0-lb
    sudo systemctl start hapee-3.0-lb

    Messages may appear, stating that backend servers are not available. This condition is expected and occurs because the default configuration file contains stubs for backend servers. Later you will modify the configuration and replace the stubs with valid server addresses.

View module dependencies Jump to heading

Available since

  • HAProxy Enterprise 2.4r1

To view the module dependencies for your installed version of HAProxy Enterprise, you can use the hapee-lb-rdepends tool that is installed with HAProxy Enterprise. This tool is located at /opt/hapee-3.0/bin/hapee-lb-rdepends.

To use the tool:

  1. Run the hapee-lb executable with the -v option to identify the version and build of your HAProxy Enterprise installation.

    nix
    /opt/hapee-2.8/sbin/hapee-lb -v
    nix
    /opt/hapee-2.8/sbin/hapee-lb -v
    output
    text
    HAProxy version 2.8.0-1.0.0-310.418 2023/12/14 - https://haproxy.org/
    [...]
    output
    text
    HAProxy version 2.8.0-1.0.0-310.418 2023/12/14 - https://haproxy.org/
    [...]

    The version is the first part of the output after “HAProxy version”. In this example it is 2.8. The build is the numbers following the first dash (-). In this example it is 1.0.0-310.418.

  2. Run the hapee-lb-rdepends tool, providing the values for the parameters --version, --build, and --key as follows:

    • --version is the version you retrieved in the previous step. For this example, version 2.8 we will specify 2.8r1 as the version.
    • --build is the build you retrieved in the previous step
    • --key is your HAProxy Enterprise license key
    nix
    /opt/hapee-3.0/bin/hapee-lb-rdepends -v "2.8r1" --build "1.0.0-310.418" --key "<HAProxy Enterprise key>"
    nix
    /opt/hapee-3.0/bin/hapee-lb-rdepends -v "2.8r1" --build "1.0.0-310.418" --key "<HAProxy Enterprise key>"

  3. The packages that HAProxy Technologies provides are signed. We encourage you to validate the fingerprints first before installing them onto your system.

    nix
    wget https://pks.haproxy.com/linux/enterprise/HAPEE-key-3.0r1.asc
    wget https://pks.haproxy.com/linux/enterprise/HAPEE-key-extras.asc
    nix
    wget https://pks.haproxy.com/linux/enterprise/HAPEE-key-3.0r1.asc
    wget https://pks.haproxy.com/linux/enterprise/HAPEE-key-extras.asc

    Then, compare the output of the following commands with the list of expected fingerprints below:

    With gpg versions < 2.1.16:

    nix

System tuning Jump to heading

To get the best performance for your particular environment, consider the following recommendations for tuning your system.

It is advisable to disable swap for performance reasons.

Enable SYSCTL features Jump to heading

In Linux, you can use the program sysctl to read and/or modify the attributes of the system kernel, including its maximum limits and security settings.

When you install HAProxy Enterprise, some recommended sysctl settings are written to its configuration file. These sysctl settings are disabled by default.

  1. Open the configuration file /etc/sysctl.d/30-hapee-3.0.conf

  2. Enable the settings by un-commenting them (remove the prefixing hash sign).

  3. Reload the file using systemctl restart systemd-sysctl.
