6.3 运行一个本地Fuel节点 (Running a local Fuel node)
In addition to deploying and testing on the Fuel Testnet, you can also run a local Fuel Node. 除了在 Fuel 测试网上进行部署和测试外,您还可以运行本地 Fuel 节点。
There are two types of Fuel networks that can be run: 可以运行两种类型的 Fuel 网络:
In-memory network (without persistance) 内存网络(非持久化)
Local network with persistance 具有持久性的本地网络
内存本地节点(非状态持久化)-In-memory local node (without state persistance)
An in-memory node does not persist the blockchain state anywhere, it is only stored in memory as long as the node is active and running.
内存节点不会在任何地方持久保存区块链状态,只要节点处于活动状态并正在运行,它就会存储在内存中。
To spin Up a local in-memory Fuel node, run the following command:
要启动本地内存中的 Fuel 节点,请运行以下命令:
fuel-core run --db-type in-memory
To deploy a contract to the local node, run the following command:
要将合约部署到本地节点,请运行以下命令:
forc deploy <signing-key> --url 127.0.0.1:4000/graphql
Or to deploy without using a signing key:
或者不使用签名密钥进行部署:
forc deploy --unsigned --url 127.0.0.1:4000/graphql
本地节点(状态持久化)Local node (with state persistance)
This node does persist the blockchain state locally.
该节点确实在本地保留区块链状态。
To run a local node with persistance, you must configure a chainConfig.json
file. Here is an example of what that looks like:
要持久运行本地节点,您必须配置一个 chainConfig.json
文件。这是一个看起来像的例子:

从浏览器钱包连接到本地节点 (Connecting to the local node from a browser wallet)
To connect to the local node using a browser wallet, import the network address as:
