Ubuntu环境
安装Geth:
sudo apt-get install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get update
sudo apt-get install ethereum
查看geth版本
dell@dell-VirtualBox:~/dapp/course$ geth version

生成genesis.json文件
dell@dell-VirtualBox:~/dapp/course$ vim genesis.json
输入
{
"nonce": "0x0000000000000042",
"difficulty": "0x200",
"mixhash": "0x0000000000000000000000000000000000000000000000000000000000000000",

}
}
初始化
geth --datadir “chain” init genesis.json
启动geth
geth --identity "myethereum" --rpc --rpccorsdomain "*" --datadir "chain" --port "30303" --rpcapi "db,eth,net,web3,personal,miner" --networkid "6500" console 2>1.txt
- –datadir : 指定当前节点存在位置,“chain”
- –identity : 区块链的标示,自定义,用于标示目前网络的名字
- –rpc : 启用http-rpc服务器,可以进行智能合约的部署和调试
- –rpcapi : 基于http-rpc提供的api接口。eth,net,web3,db…
- –rpcaddr : http-rpc服务器接口地址:默认“127.0.0.1”
- –rpcport : http-rpc端口(多节点时,不要重复)
- –port : 节点端口号(多节点时,不要重复)
- –networkid : 网络标识符 随便指定一个id(确保多节点是统一网络,保持一致)
- –console :启动命令行模式,可以在Geth中执行命令
> eth.blockNumber
0
> personal.newAccount("account1")
"0x22b7d9435328d56266d8ea9a7def7d3366133bd4"
> eth.accounts
["0x22b7d9435328d56266d8ea9a7def7d3366133bd4"]
> miner.start()
null
> eth.mining
true
> miner.stop()
null
> eth.mining
false
