In this section, we will configure the virtual machines and install, and configure the environment. In the other other sections we will play with the environment.

We will use:

• Vagrant - For Virtualization
• Ubuntu - For Operation System
• 2nd Quandrant - For Rempgr

To configure the Virtual Environment, we will use Vagrant and Ubuntu machines. You can configure the following vagrant file:

C:\Virtual Box\REPMGR>vagrant init
A `Vagrantfile` has been placed in this directory. You are now
ready to `vagrant up` your first virtual environment! Please read
the comments in the Vagrantfile as well as documentation on
`vagrantup.com` for more information on using Vagrant.

C:\Virtual Box\REPMGR>vagrant status
Current machine states:

server1                   not created (virtualbox)
server2                   not created (virtualbox)

This environment represents multiple VMs. The VMs are all listed
above with their current state. For more information about a specific
VM, run `vagrant status NAME`.

C:\Virtual Box\REPMGR>vagrant up

***************************************

The vagrant file is the following:

Vagrant.configure("2") do |config|
  (1..2).each do |n|
    config.vm.define "server#{n}" do |define|
      define.vm.box = "bento/ubuntu-20.04"
      define.ssh.insert_key = false
      define.vm.hostname = "server#{n}"
      define.vm.network :private_network, ip: "10.0.15.2#{n}"

      define.vm.provider "virtualbox" do |node|
        node.name = "server#{n}"
      end
    end
  end
end

Once the machines are up, we can start with the installation. Bare in mind that this vagrant will automatically configure the IPs as well, but will not configure /etc/hosts. Something which we will do now.

For the servers we have to:

1. Configure /etc/hosts
2. Configure 2nd Quadrant Repository
3. Install 2nd Quadrant Packages

So, let's get going.

That is pretty trivial, just add the IPs and the hostnames to /etc/hosts:

10.0.15.21 server1
10.0.15.22 server2

That will allow, the hosts to see and ping each other.

Then we can configure the repositories:

I decided to use 2nd quadrant packages, as they are the ones I use for work as well :)
