1. Initial configuration
Create a service user for the consensus service, create data directory and assign ownership.
sudo adduser --system --no-create-home --group consensus
sudo mkdir -p /var/lib/lodestar
sudo chown -R consensus:consensus /var/lib/lodestar
Install dependencies.
sudo apt-get install gcc g++ make git curl -y
2. Install Binaries
Building from source code can offer better compatibility and is more aligned with the spirit of FOSS (free open source software).
3. Setup and configure systemd
Create a systemd unit file to define your consensus.service
configuration.
sudo nano /etc/systemd/system/consensus.service
Paste the following configuration into the file.

Now that your consensus client is configured and started, you have a full node.
Proceed to the next step on setting up your validator client, which turns a full node into a staking node.
