9.1 Preparing the Server Environment

Before installing the FreCx node, the system must be updated, and essential tools must be installed.

Updating System Packages

Run the following command to update the package list:

sudo apt update

This command retrieves the latest list of available packages and versions.

To upgrade installed packages:

sudo apt upgrade -y

This ensures that all system packages are up to date.

Installing Required Dependencies

FreCx node setup typically requires basic tools such as Git, curl, and build utilities.

Install them using:

sudo apt install -y git curl wget build-essential

This installs:

• git for downloading source code

• curl and wget for network operations

• build-essential for compiling dependencies

Verify installation:

git --version

Installing Node.js (if required)

Some FreCx components or tooling may require Node.js.

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt install -y nodejs

Verify:

node -v
npm -v

Installing Docker (Optional but Recommended)

Docker simplifies node deployment and environment management.

sudo apt install -y docker.io
sudo systemctl start docker
sudo systemctl enable docker

Verify Docker:

docker --version
