Exabeam Product Deployment in On-premises or Virtual Environments

Hardware and Virtual Deployments Only

Before installing Exabeam products, ensure you have deployed the supported operating system and configurations. Please review all instructions for setting up hosts that will run Exabeam tasks. See the setup guides that apply to your operating environment.

There are a series of prerequisites to implement before installing Exabeam products. There are a number of ports, protocols, and URLs that must be opened and white-listed. We highly recommend reading through the ??? and tackling these requirements early. This will ensure that the setup goes smoothly and quickly.

Installation Pre-Check for Exabeam Products

Hardware and Virtual Deployments Only

When deploying your Exabeam product, a series of automated pre-checks test your platform to ensure servers meet Exabeam's requirements in terms of available resources (memory, CPU, disks), OS configuration, etc. Any failures or warnings indicate your system will likely fail to deploy, and should be remedied before continuing.

A successful pre-check will conclude with All checks passed.

An unsuccessful pre-check will conclude the following messages and it is advised you do not upgrade until checks have passed.

Troubleshooting an Installation

Hardware and Virtual Deployments Only

Ansible Failure

If the installer fails during an ansible script (when all of the timestamped tasks are cascading down the screen), the steps to restart the deployment after fixing are:

  1. Navigate to the Menu:

    /opt/exabeam_installer/init/exabeam-multinode-deployment.sh
  2. Select option: Deploy cluster.

Error: Multiple Interfaces Detected

Root Cause: multiple interfaces are defined on boot

Steps to re-mediate:

  1. Examine the output of the following command. Look for the iface of the current box for reference (helps know what iface not to touch)

    ip a
  2. Look at the defined interfaces:

    cat /etc/sysconfig/network-scripts/ifcfg*
  3. Only one interface (excluding the loopback interface ifc-lo) should have 'ONBOOT=yes'. Change the extra interface files from ONBOOT=yes to ONBOOT=no

    Requires sudo access to edit these files.

  4. Run

    sudo systemctl restart network
  5. Confirm consul is running

    sudo systemctl status consul
  6. Restart the deployment process

    /opt/exabeam_installer/init/exabeam-multinode-deployment.sh
