Fuel Node Setup Guide

Recommended Hardware Requirements

- Memory: 12 GB
- CPU: 8 cores
- Disk: 100 GB NVME SSD

Preparation

Update packages

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

Install essential packages

sudo apt install git wget curl lz4 build-essential -y

Install Rustup

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

Configure your current shell

. "$HOME/.cargo/env"

Check rustc version

rustup --version

***Result***

rustup 1.27.1 (54dd3d00f 2024-04-24)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.79.0 (129f3b996 2024-06-10)`

Installation

Install fuelup

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

add fuelup to path

export PATH="${HOME}/.fuelup/bin:${PATH}"

Check fuelup version

fuelup --version

***Result***

fuelup 0.25.1

Generate P2P key and save your secret key somewhere safe

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

***Result***

{"peer_id":"16Uiu2HAmU3UZczJCRqdWcgyDL2r3qEqDa9psDXwg1gDCP6kCy9na",
"secret":"098b29f38f0b8a2fd67d441128675e058d7710a90698588101547a86fe3eeb85",
"type":"peering"}

Create a data directory and clone chain-configuration file

mkdir .fueld
git clone https://github.com/FuelLabs/chain-configuration chain-configuration && cp -r $HOME/chain-configuration/ignition/* $HOME/.fueld/

Create systemd service for fuel (edit your own node's name, secret key and sepolia rpc)

sudo tee /etc/systemd/system/fueld.service > /dev/null << EOF

Reload, Enable and Start the fueld service

sudo systemctl daemon-reload && \
sudo systemctl enable fueld && \
sudo systemctl start fueld && \
sudo journalctl -u fueld -f -o cat

to check the logs again

sudo journalctl -u fueld -f -o cat

to restart the node

sudo systemctl restart fueld && sudo journalctl -u fueld -f -o cat

Download Snapshot

Updated at Block #3862556

Stop the fueld.service

sudo systemctl stop fueld

Download latest snapshot

Install aria2 download utility

sudo apt install aria2

Download the snapshot

aria2c -x 16 -s 16 -k 1M -d /tmp -o snapshot.tar.lz4 http://109.199.108.37/fuel-sepolia-snapshot.tar.lz4 && \
lz4 -dc /tmp/snapshot.tar.lz4 | tar -xf - -C $HOME/.fueld && \
rm -rf $HOME/.fueld/on_chain && \
mv -f $HOME/.fueld/.fuel-sepolia-testnet/on_chain $HOME/.fueld/

Restart the service and check the log

sudo systemctl restart fueld && sudo journalctl -u fueld -f -o cat
