1.新建genesis.json
{
"config": {
"chainId": 666,
"homesteadBlock": 0,
"eip150Block": 0,
"eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"eip155Block": 0,
"eip158Block": 0,
"byzantiumBlock": 0,
"constantinopleBlock": 0,
"petersburgBlock": 0,
"istanbulBlock": 0,
"ethash": {}
},
"nonce": "0x0",
"timestamp": "0x5ddf8f3e",
"extraData": "0x0000000000000000000000000000000000000000000000000000000000000000",
"gasLimit": "0x47b760",
"difficulty": "0x00002",
"mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000",
"coinbase": "0x0000000000000000000000000000000000000000",
"alloc": {
"0x1e82968C4624880FD1E8e818421841E6DB8D1Fa4" : {"balance" : "30000000000000000000"}
},
"number": "0x0",
"gasUsed": "0x0",
"parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000"
}
各個參數的解釋可參考：https://www.cnblogs.com/wanghui-garcia/p/10256520.html
如果沒有alloc后面的部分，可能出現：Fatal: Failed to write genesis block: unsupported fork ordering: eip150Block not enabled, but eip155Block enabled at 0 錯誤

2.啟動
2.1.初始化
geth --datadir /usr/geth/data init /usr/geth/config/genesis.json
2.2.啟動私鏈並進入控制台
geth --datadir /usr/geth/data --networkid 666 console
3.創建賬戶挖礦
3.1.創建賬戶
personal.newAccount() 然后根據提示輸入密碼
personal.newAccount("123456") 創建賬戶的同時指定密碼
3.2.挖礦
miner.start(1) 括號里不填的話是默認全力挖礦
3.3.停止
miner.stop() 停止挖礦
