私链多节点的创建部署

首先创世区块json文件，可以命名为 genesis.json

{
  "config": {
    "chainId": 20220721,
    "homesteadBlock": 0,
    "eip150Block": 0,
    "eip150Hash": "0x0000000000000000000000000000000000000000000000000000000000000000",
    "eip155Block": 0,
    "eip158Block": 0,
    "byzantiumBlock": 0,
    "constantinopleBlock": 0,
    "petersburgBlock": 0,
    "istanbulBlock": 0,
    "ethash": {}
  },
  "nonce": "0x0",

2、add-apt-repository -y ppa:ethereum/ethereum

3、apt-get update

4、apt-get install ethereum

geth version 查看版本

(1) geth --datadir data1 init genesis.json  进行初始化

(2) geth --datadir data1/ --networkid 20220721  --http --http.addr "0.0.0.0" --http.port 8546 --http.corsdomain "*" --http.vhosts "*" --port 30306 --http.api "eth,web3,miner,admin,personal,net" --nodiscover --ipcdisable --allow-insecure-unlock console --syncmode "full" --maxpeers 100
