One of the computers will act as a control node, the rest will be divided into metadata storage and compute nodes.

Installation

1. Install Ubuntu 20.04 LTS Beta on all the nodes. (It is not working with the 20.04.02 due to kernel changes).

2. Set a static ip address in all nodes and then restart the network

3. In all nodes but the control node do the following:

• Set a root user password and run the following commands:

  sudo apt update
  
  ```sh
  sudo apt install ssh

• Edit /etc/ssh/sshd_config file and set PermitRootLogin yes
• Run

  sudo service sshd restart

4.- In the control node do the following:

• Clone this repository and cd into the repo folder

• Run

  sudo apt install ansible

• For each node

  ssh-copy-id root@[ip_address]

  where ip_address is the static ip previously set for each node.
