擅长：智能合约,以太坊 1. 准备创始文件（init.json） 大概是这样： ```json { "config": { "chainId": 1234, "homesteadBlock": 0, "eip150Block": 0, "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000", "eip155Block": 0, "eip158Block": 0, "byzantiumBlock": 0, "constantinopleBlock": 0, "petersburgBlock": 0, "ethash": {} }, "nonce": "0x0", "timestamp": "0x5dcba32c", "extraData": "0x0000000000000000000000000000000000000000000000000000000000000000", "gasLimit": "0x97b760", "difficulty": "0x200000", "mixHash": "0x0000000000000000000000000000000000000000000000000000000000000000", "coinbase": "0x0000000000000000000000000000000000000000", "alloc": { "你的初始账号 1": { "balance": "0x200000000000000000" }, "你的初始账号 2": { "balance": "0x200000000000000000" }, "你的初始账号 3: { "balance": "0x200000000000000000" } }, "number": "0x0", "gasUsed": "0x0", "parentHash": "0x0000000000000000000000000000000000000000000000000000000000000000" } ``` 2. 初始化世纪块 ``` geth --datadir data init init.json ``` 3. 启动节点，开始挖矿 ``` geth --datadir data --networkid 1234 --unlock '挖矿账号' --password 'pwd.txt' --rpc --mine --allow-insecure-unlock console ``` 这时候，找到enode， 以供其他节点链接： ``` enode://xxx@peerIP:30303 ``` 使用： miner.start() 开启挖矿 4. 其他节点加入 ``` geth --datadir data --syncmode 'full' --networkid 1234 --bootnodes 'enode:// xxxx@ip:30303' --unlock '挖矿账号2' --password 'pwd.txt' --mine ``` 这样就搭建好了两个节点，其他的节点同理。
