geth init genesis.json


// 主网id是1,测试网络是2/3/4.

geth --networkid 10 --rpc --rpcapi "admin,debug,eth,miner,net,personal,shh,txpool,web3" rpcaddr "0.0.0.0" --rpccorsdomain "*" --nodiscover --dev console

打开, mist 钱包 ,自动进入私链

创建钱包;

另开一个终端:

geth attach 'http://127.0.0.1:8545'

miner.start(1)

//如果出现端口被占用
lsof -i:30303
//找到pid
kill -9 pid
//如果没有lsof 的话..
brew install lsof
