下载 geth(注意查看磁盘空间)

解压tar

新建json文件(genesis.json)

./geth -datadir "data" init init.json   //初始化创世区块

 

 ./geth -datadir "data" console          //在创建的创世区块上执行交互操作

创建地址

personal.newAccount("pwd")

设置变量接收account

my=eth.accounts[0]

查看余额

eth.getBalance(my)

开始挖矿

miner.start()

结束挖矿

miner.stop()

查看余额

eth.getBalance(my)

再创建几个地址

personal.newAccount("pwd")

用other接收

other = eth.accounts[1]

开始转账

解锁转出账户

personal.unlockAccount(my)

给other转账

eth.sendTransaction({from:my,to:other,value:1000})

查看余额

eth.getBalance(my)

eth.getBalance(other)

转账未到账

再挖矿

miner.start()

miner.stop()

再查看余额

eth.getBalance(my)

eth.getBalance(other)

设置rpc访问（注册需要关闭之前的console）

./geth --datadir data/ --allow-insecure-unlock --rpc --rpcaddr "0.0.0.0" -rpcport "8545" --rpcapi "db,eth,net,web3,miner,personal,admin"  --rpccorsdomain "*" console
