Installation methods

Installation methods 🔧

We have created a Vagrantfile through which we provide each machine with the necessary scripts to install and configure the scenario. By working in a virtualized environment we make sure we all have the exact same configuration so that tracing and fixing errors becomes much easier. If you do not want to use Vagrant as a provider you can follow the native installation method we present below.

Vagrant

First of all, clone the repository from GitHub and navigate into the new directory with:

git clone https://github.com/GAR-Project/project
cd project

We power up the virtual machine through Vagrant:

vagrant up

And we have to connect to both machines. Vagrant provides a wrapper for the SSH utility that makes it a breeze to get into each virtual machine. The syntax is just vagrant ssh <machine_name> where the <machine_name> is given in the Vagrantfile (see the appendix):

vagrant ssh test
vagrant ssh controller

We should already have all the machines configured with all the necessary tools to bring our network up with Mininet on the test VM, and Ryu on the controller VM. This includes every python3 dependency as well as any needed packages.

Troubleshooting problems regarding SSH

If you have problems connecting via SSH to the machine, check that the keys in the path .vagrant/machines/test/virtualbox/ are owned by the user, and have read-only permissions for the owner of the key.

cd .vagrant/machines/test/virtualbox/
chmod 400 private_key

# We could also use this instead of "chmod 400" (u,g,o -> user, group, others)
# chmod u=r,go= private_key

Instead of using vagrant's manager to make the SSH connection, we can opt for manually doing it ourselves by passing the path to the private key to SSH. For example:

ssh -i .vagrant/machines/test/virtualbox/private_key vagrant@10.0.123.2

Native

This method assumes you already have any VMs up and running with the correct configuration and dependencies installed. Ideally you should have 2 VMs. We will be running Ryu (the SDN controller) in one of them and we will have mininet's emulated network with running in the other one. Try to use Ubuntu 16.04 (a.k.a Xenial) as the VM's distribution to avoid any mistakes we may have not encountered.

First of all clone the repository (just like how the Kaminoans 👽 do it) and then navigate into it:

git clone https://github.com/GAR-Project/project
cd project

Manually launch the provisioning scripts in each machine:

# To install Mininet, Mininet's dependencies and telegraf. Run it on the "mininet" VM
sudo ./util/install_mininet.sh
sudo ./util/install_telegraf.sh

# To install Ryu and Monitoring system (Grafana + InfluxDB). Run it on the "controller" VM
sudo ./util/install_ryu.sh
sudo ./util/install_grafana_influxdb.sh
