KYTOS INSTALLATION TUTORIAL

Step 1: Installing Python 3.11.x

1. Update the package repositories:

sudo apt update

2. Add the Python 3.11 PPA repository:

sudo add-apt-repository ppa:deadsnakes/ppa

3. Update the repositories again and install Python 3.11 along with essential development tools:

sudo apt update
        sudo apt install python3.11-dev python3.11-venv

Step 2: Installing Requirements

1. Install Git, required for cloning repositories:

sudo apt install git

Step 3: Creating and Activating a Virtual Environment

1. Create a virtual environment named test using Python 3.11:

python3.11 -m venv test

2. Activate the virtual environment:

source test/bin/activate

Inside the virtual environment, you will see the prefix (test) at the beginning of the terminal.

Step 4: Installing Dependencies in the Virtual Environment

1. Upgrade pip, setuptools, and wheel:

pip install --upgrade pip setuptools wheel

Step 5: Downloading and Installing Kytos-ng

1. Clone the main Kytos-ng repositories:

For repo in python-openflow kytos-utils kytos; execute git clone:

https://github.com/kytos-ng/"${repo}"

2. Clone the Kytos-ng Napps (Network Applications) repositories:

For repo in of_core flow_manager topology of_lldp of_l2ls; execute git clone:

https://github.com/kytos-ng/"${repo}"

3. Install the packages locally in "editable" mode (to allow local modifications):

For repo in of_core flow_manager topology of_lldp of_l2ls; execute:

cd "${repo}" 
        python -m pip install --editable . 
        cd ..

If there are errors, you can manually proceed with the commands below:

python3 -m pip install -e git+https://github.com/kytos-ng/mef_eline@master#egg=kytos-mef_eline
        python3 -m pip install -e git+https://github.com/kytos-ng/sdntrace_cp@master#egg=amlight-sdntrace_cp
        python3 -m pip install -e git+https://github.com/kytos-ng/coloring@master#egg=amlight-coloring
        python3 -m pip install -e git+https://github.com/kytos-ng/pathfinder@master#egg=kytos-pathfinder

Step 6: Installing MongoDB (Locally)

Update the system and add the GPG key for the official MongoDB repository:

sudo apt-get update
        sudo apt-get install gnupg 
        wget -qO - https://www.mongodb.org/static/pgp/server-6.0.asc | sudo apt-key add -
        echo "deb [arch=amd64,arm64] https://repo.mongodb.org/apt/ubuntu focal/mongodb-org/6.0 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-6.0.list

Update the repositories and install MongoDB:

sudo apt-get update
        sudo apt-get install -y mongodb-org

Start MongoDB and enable it to start automatically on system reboot:

sudo systemctl start mongod
        sudo systemctl enable mongod

Check the status of MongoDB:

sudo systemctl status mongod
