Question

我正在创建一个私人网络（以太坊）。我写了genesis.json文件（下面的代码），然后我没有错误地初始化它，但是当我尝试连接它时，创建了一个新行（暗示应该指定一个额外的命令）。当我按回车键时，geth只是连接到主网络。如何让geth连接到专用网络？

注意：您可以立即告知geth连接到主网络，因为我的链ID是 15 ，它显示与 1 的连接。

genesis.json：

{
  "difficulty" : "0x20000",
  "extraData"  : "",
  "gasLimit"   : "0x8000000",
  "alloc": {},
  "config": {
        "chainId": 15,
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    }
}

命令行：

Answer 1

启动--networkid时，您错过了geth。

geth --networkid 15 --datadir mychaindata

Answer 2

您缺少--networkid和其他导入参数，如端口等。使用以下命令连接到您的网络。

geth --networkid 15 --datadir .\mychaindata

geth的其他参数低于

geth --networkid <chainId> 
     --mine 
     --datadir <datadir> 
     --nodiscover 
     --rpc --rpcport "8545" 
     --port "30303" 
     --rpccorsdomain "*" 
     --nat "any" 
     --rpcapi eth,web3,personal,net 
     --unlock 0 
     --password <password file> 
     --ipcpath <path to .ipc file>

Geth未能连接到私人网络
