Metron on CentOS 6

This project fully automates the provisioning and deployment of Apache Metron and all necessary prerequisites on a single, virtualized host running CentOS 6.

Metron is composed of many components and installing all of these on a single host, especially a virtualized one, will greatly stress the resources of the host. The host will require at least 8 GB of RAM and a fair amount of patience. It is highly recommended that you shut down all unnecessary services.

Getting Started

Prerequisites

The computer used to deploy Apache Metron will need to have the following components installed.

Ansible (2.0.0.2, 2.2.2.0, or 2.5.0)
Docker
Vagrant 2.0+
Vagrant Hostmanager Plugin
Virtualbox 5.0+
Python 2.7
Maven 3.3.9
C++11 compliant compiler, like GCC

Running the following script can help validate whether you have all the prerequisites installed and running correctly.

metron-deployment/scripts/platform-info.sh

How do I install these on MacOS?

Any platform that supports these tools is suitable, but the following instructions cover installation on macOS. The easiest means of installing these tools on a Mac is to use the excellent Homebrew project.

Install Homebrew by following the instructions at Homebrew.

Run the following command in a terminal to install all of the required tools.

brew cask install vagrant virtualbox docker
brew cask install caskroom/versions/java8
brew install maven@3.3 git
pip install ansible==2.2.2.0
vagrant plugin install vagrant-hostmanager
open /Applications/Docker.app

Deploy Metron

Ensure that the Docker service is running.
Deploy Metron
```
cd metron-deployment/development/centos6
vagrant up
```
Should the process fail before completing the deployment, the following command will continue the deployment process without re-instantiating the host.
```
vagrant provision
```

Explore Metron

Navigate to the following resources to explore your newly minted Apache Metron environment.

Connecting to the host through SSH is as simple as running the following command.

vagrant ssh

Working with Metron

In addition to re-running the entire provisioning play book, you may now re-run an individual Ansible tag or a collection of tags in the following ways. The following commands will re-run the sensor-stubs role on the Vagrant image. This will install and start the sensor stub components.

vagrant --ansible-tags="sensor-stubs" provision

Tags are listed in the playbooks, some frequently used tags:

hdp-install - Install HDP
hdp-deploy - Deploy and Start HDP Services (will start all Hadoop Services)
sensors - Deploy and start the sensors.
sensor-stubs - Deploy and start the sensor stubs.
