Fedora 27、CentOS 1708、Go-ethereum 1.8.1
我正在尝试使用它来制作私人区块链和硬币用于研究。
创世纪.json：
{
"config": {
"chainId": 42,
"homesteadBlock": 0,
"eip155Block": 0,
"eip158Block": 0
},
"alloc": {},
"coinbase" : "0x0000000000000000000000000000000000000000",
"difficulty" : "0x1000000",
"extraData" : "",
"gasLimit" : "0x2fefd8",
"nonce" : "0x0000000012345678",
"mixhash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"parentHash" : "0x0000000000000000000000000000000000000000000000000000000000000000",
"timestamp" : "0x00"
}
我在控制台中运行 geth：
geth init genesis.json --datadir datadir
geth console --rpc --rpcport "8080" --rpccorsdomain "*" --datadir "datadir" --port "30303" --nodiscover --rpcapi "db,eth,net,web3" --networkid 7296
然后我创建了新帐户并开始挖矿。有用。但是当我重新启动geth时，区块链状态似乎没有保存。

如何解决？我可以在退出 geth 后保持区块链状态吗？
