使用P2P运行连接到测试网的本地 Fuel 节点
安装
要安装 Fuel 工具链，你可以使用 fuelup-init 脚本。
这将安装 forc、forc-client、forc-fmt、forc-lsp、forc-wallet 以及 fuel-core 到 ~/.fuelup/bin。
curl https://install.fuel.network | sh 要运行一个 testnet 节点，您需要安装 testnet 工具链。
您可以通过运行以下命令来执行此操作。
fuelup toolchain install testnet
fuelup default testnet获取 Sepolia（以太坊测试网）API 密钥
任何支持 Sepolia 网络的 RPC 提供者的 API 密钥都可以使用。中继器将帮助监听以太坊网络的事件。我们推荐使用 Infura 或 Alchemy
端点应如下所示：
Infura
https://sepolia.infura.io/v3/{YOUR_API_KEY}Alchemy
https://eth-sepolia.g.alchemy.com/v2/{YOUR_API_KEY}请注意，使用其他网络端点将导致中继器无法启动。
生成 P2P 密钥
通过运行以下命令生成新的 P2P 密钥对：
fuel-core-keygen new --key-type peering
{
"peer_id":"16Uiu2HAmEtVt2nZjzpXcAH7dkPcFDiL3z7haj6x78Tj659Ri8nrs",
"secret":"b0ab3227974e06d236d265bd1077bb0522d38ead16c4326a5dff2f30edf88496",
"type":"peering"
}
### Do not share or lose this private key! Press any key to complete. ###确保您将其安全保存，以便将来无需生成新的密钥对。
链配置
要运行带有持久性的本地节点，您必须拥有以下链配置文件夹：
