Blockchain 以太坊geth无法连接到bootnode以访问私有以太坊网络

Blockchain 以太坊geth无法连接到bootnode以访问私有以太坊网络,blockchain,ethereum,go-ethereum,geth,Blockchain,Ethereum,Go Ethereum,Geth,以下docker compose.yml用于启动以太坊geth节点,该节点需要连接到引导节点才能访问专用以太坊网络 version: '2' geth: image: ethereum/client-go:latest volumes: - ./node:/root/.ethereum - ./files/genesis.json:/root/genesis.json:ro ports: - "30303:303

以下
docker compose.yml
用于启动以太坊
geth
节点,该节点需要连接到引导节点才能访问专用以太坊网络

version: '2' 

    geth:
    image: ethereum/client-go:latest
    volumes:
        - ./node:/root/.ethereum
        - ./files/genesis.json:/root/genesis.json:ro
    ports:
        - "30303:30303"
        - "30303:30303/udp"
        - 8543:8545
    command: --rpc --rpcaddr 0.0.0.0 --networkid 13377331 --bootnodes="enode://692b8eda368ffc427fc1a047850557536a0ef0bfa3b66f998e03e8b83c3fd8f786e3c2b710a20e2e821a9eff34fc7b34ffa326a8a5fbcf3634b55b44596ada43@159.999.999.999:30303" --nodiscover
但是,在运行了
docker compose up
之后,我们看到回显的链配置是默认配置,而不是bootnode正在使用的配置

初始化链配置配置=“{ChainID:1 Homestead:1150000 DAO:1920000 DAO支持:true EIP150:2463000 EIP155:2675000 EIP158:2675000拜占庭:4370000君士坦丁堡:引擎:ethash}”

问题:为什么
geth
没有连接到bootnode,并且没有使用bootnode在其
genesis.json
中的配置

docker编写输出:

看起来您使用的是默认的datadir,而不是用genesis.json初始化的私有datadir。因此,geth通过使用默认的datadir(请参见输出中的
database=/root/.ethereum/geth/chaindata
versions=“[63 62]”network=1
)作为主网络节点启动

要启动专用节点,请尝试以下步骤:

  • 使用genesis.json初始化geth datadir。例如:

    geth--datadir path/to/custom/data/folder init genesis.json

  • 使用datadir和networkid启动geth。例如:

    geth--datadir path/to/custom/data/folder--networkid 13377331

  • 请注意,这些步骤使用
    --datadir
    选项


    有关更多信息,请参阅。

    将来可能帮助您进行网络对等的一般说明

    • 网络上的不同节点将始终具有不同的端口和rpcports
    • 引导节点充当不同网络(如果需要,甚至在同一网络上)上的对等节点的连接节点。因此,最好知道承载bootnode的机器的IP地址,并在添加的对等机上调用Geth时引用它
    • Genesis文件应始终相同,即使跨不同的节点。您可以在Genesis文件中声明所有签名者,甚至在其他机器上旋转节点之前,也可以在之后添加签名者
    • 所有对等节点的网络ID也相同
