2024 最新 fuel 运行节点指南

1.下载，curl <https://install.fuel.network> | sh

2.输入 y，

3.设置链和安装测试网：

fuelup toolchain install testnet

fuelup default testnet

4.设置环境变量为全局：export PATH="${HOME}/.fuelup/bin:${PATH}", 检查是否安装成功： fuelup --version fuel-core --version

如果成功会出现：fuel-core 0.26.0

5.使用 <https://www.alchemy.com/> 创建一个 dapp，选择测试网络 Sepolia 。

6.使用命令生成一个 p2p 的 key，记得保存下来，fuel-core-keygen new --key-type peering

7.克隆 chain 的配置，使用命令：git clone https://github.com/FuelLabs/chain-configuration.git 后面会用到这个文件夹

8.运行启动命令：修改 P2P_PRIVATE_KEY 为上一步生成的 key， ETHEREUM_RPC_ENDPOINT 改为 alchemy 的 https 节点

提示：{P2P_PRIVATE_KEY}，{ETHEREUM_RPC_ENDPOINT} 这里不需要{} 直接输入 key 和 url 地址

fuel-core run \
--service-name=fuel-sepolia-testnet-node \
--keypair {P2P_PRIVATE_KEY} \
--relayer {ETHEREUM_RPC_ENDPOINT} \
--ip=0.0.0.0 --port=4000 --peering-port=30333 \
--db-path=~/.fuel-sepolia-testnet \
--snapshot /root/chain-configuration/ignition/ \
--utxo-validation --poa-instant false --enable-p2p \
--reserved-nodes /dns4/p2p-testnet.fuel.network/tcp/30333/p2p/16Uiu2HAmDxoChB7AheKNvCVpD4PHJwuDGn8rifMBEHmEynGHvHrf \
--sync-header-batch-size 100 \
--enable-relayer \
--relayer-v2-listening-contracts=0x01855B78C1f8868DE70e84507ec735983bf262dA \
--relayer-da-deploy-height=5827607 \
--relayer-log-page-size=500 \
--sync-block-stream-buffer-size 30

运行成功后，会看到输出的节点信息，等待一段时间后会有区块同步：

然后退出这个进程，ctrl+c 退出，然后使用 /etc/systemd/system/fuel-core.service 监控服务，使用下面的命令进行设置，需要修改对应的信息！！！

sudo tee <<EOF >/dev/null /etc/systemd/system/fuel-core.service

设置成功后，运行后台运行命令 sudo systemctl enable fuel-core

启动节点：sudo systemctl start fuel-core

检查是否启动成功： sudo systemctl status fuel-core

查看执行的日志： sudo journalctl -u fuel-core.service -f
