Ethereum Geth无法连接到专用网络

我正在创建一个专用网络（以太坊）。我编写了genesis.json文件（下面的代码），然后对其进行了初始化，没有错误，但是当我尝试连接到它时，会创建一个新行（意味着应该指定一个额外的命令）。当我按enter键时，geth只是连接到主网络。如何让geth连接到专用网络

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

genesis.json：

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

命令行：

Ryan-Cocuzzos-Laptop:BlockDev Ryan$ geth init ./genesis.json --datadir mychaindata

启动

geth

时您缺少

--networkid

geth--网络ID 15--datadir mychaindata

缺少

--networkid

和其他导入参数，如端口等。 使用下面的命令连接到您的网络

geth --networkid 15 --datadir .\mychaindata

geth

的其他参数如下

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>
