FUEL

This guide will detail the installation of a node in the Fuel project.

Server requirements(recommended):

• CPU: 8 cores;

• RAM: 12 GB;

• Storage: 100 GB SSD

• OS: Ubuntu 22.04

1. Let's update the packages:

sudo apt-get update && sudo apt-get upgrade -y

1. Let's install the wget and curl tools:

 sudo apt install wget curl

1. Let's install Rust:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs/ | sh

1. Customize the current shell:

. "$HOME/.cargo/env"

1. Check the version of Rust:

rustup --version

1. Install Fuel toolchain. During the installation process, press "y" to confirm the installation:

curl https://install.fuel.network | sh

1. source /root/.bashrc

2. Let's check the Fuel version:

fuelup --version

1. Let's check the toolchain version:

fuelup show

1. Create a new P2P key pair:

fuel-core-keygen new --key-type peering

A window with keys will open, you need to save the keys. Highlight the entire contents of the opened window, copy it via CTRL+C and transfer it to notepad. The previously opened window will close. 11. Create a "fuel" folder:

mkdir fuel

1. Let's move to "fuel":

cd fuel

1. Download the official configuration file to run the node:

wget https://raw.githubusercontent.com/FuelLabs/fuel-core/v0.22.0/deployment/scripts/chainspec/beta_chainspec.json

1. Go to Alchemy, create a new App, open "API key" and copy the HTTPS link:

2. Create a service file for the node to run in the background: Replace the following parameters with their own values: <NODE_NAME> for any node name; <P2P_SECRET> to the secret key from step 10, we copied it; <SepoliaETH_RPC_ENDPOINT> to the copied HTTPS link from Alchemy.

I attach my service file for an example:

echo "[Unit]

[Install]
WantedBy=multi-user.target" > /etc/systemd/system/fueld.service

After substituting your own values, paste this command into the server window and press Enter.

1. Let's perform a daemon reload:

systemctl daemon-reload

1. Enable the node service:

systemctl enable fueld

1. Start the node service:

systemctl start fueld

1. Check the status of fueld.service:

systemctl status fueld.service

1. Lastly, let's check the logs:

journalctl -u fueld -f -o cat

Alchemy will start displaying queries

At this point, the installation of the Fuel node has come to an end.

A list of useful commands is provided below:

1. Stopping the node service file:

systemctl stop fueld

1. Deleting the node service file:

 rm /etc/systemd/system/fueld.service

1. Deleting node folders:

rm -rf fuel 
rm -rf .fuelup 
rm -rf .forc 
rm -rf .fuel_beta5

1. Checking the logs:

journalctl -u fueld -f -o cat

1. fuel-core run --help
