[区块链]linux搭建geth私有节点

linux创建节点

下载文件并上传服务器解压：Downloads | Go Ethereum

?

然后把geth复制到/usr/bin目录下面，我们就可以使用geth命令了，geth version，出现下的界面，表示成功。?

}

然后执行初始化区块的命令：

geth --datadir /usr/local/gethNodedata init /usr/local/gethNodedata/first.json

?初始化成功?

启动节点， 进入控制台，然后创建挖矿账户 进行挖矿

geth --http --http.addr 0.0.0.0 --nodiscover --datadir  "/usr/local/gethNodedata"  --port 30303 --http.api "personal,eth,net,web3,admin,ethash,miner" --http.port 18545 --http.corsdomain "*" --networkid 666 --ipcdisable  --miner.gaslimit 2000000000  console 2>>/usr/local/gethNodedata/geth.log

//创建初始账户
personal.newAccount("test")    

//开启挖矿 线程1个
miner.start(1)

//获取当前区块高度
eth.blockNumber

//获取地址账户余额
eth.getBalance("0x4ec1ed38a950edb10aba057719a702")

停止挖矿

miner.stop()

exit 退出控制台，同时也听着了geth进程

把进程转入后台执行

nohup geth --http --http.addr 0.0.0.0 --nodiscover --datadir  "/usr/local/gethNodedata"  --port 30303 --http.api "personal,eth,net,web3,admin,ethash,miner" --http.port 8545 --http.corsdomain "*" --networkid 666 --ipcdisable  --mine  --miner.gasprice 0 --miner.threads 1 --miner.gaslimit 2000000000 --allow-insecure-unlock  2>>/usr/local/gethNodedata/geth.log &
