使用geth客户端搭建私有链，操作流程如下。

1. 生成账户

geth account new

输入密码

生成密钥库文件

（默认路径为C:\Users\Administrator.DESKTOP-WANGHAO\AppData\Roaming\Ethereum）

2.将上面的keystore文件复制到自己的数据目录data0中 3.创建区块配置，在alloc字段中填写生成的账户，分配初始以太坊以太坊私链如何确认区块，如下。

}

4、将每个账号对应的密码文件（带回车换行）放入data0同级目录，保存为pwd。

注意：

"extraData": "0x0000000000000000000000000000000000000000000000000000000000000000e578252579e5f43fe124fe1d8236f0e5250c11970000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000"

矿工账户的密钥库必须可用。

5.初始化geth

geth --datadir data0 init Genesis.json

6.开始geth

geth --networkid 1818 --datadir "./data0" --rpc -rpcaddr="0.0.0.0" --rpcport 7545 --rpcapi "web3,personal,admin,db,net,eth,miner,rpc,txpool,clique" --ws -wsaddr="0.0.0.0" --wsport 8546 --wsapi "web3,personal,admin,db,net,eth,miner,rpc,txpool,clique" --wsorigins "*" --unlock 0,1,2,3 --password pwd --targetgaslimit 0x247b760 --nodiscover --gcmode archive console
