>docker pull ethereum/client-go

>cd docker_ethereum/
>[root@mo-cn-491 docker_ethereum]# ls
data  start_ethereum.sh

start-ethereum.sh的內容如下

docker stop ethereum-node
docker rm ethereum-node

docker run -d --name ethereum-node -v /home/[email protected]/hrs_doc/docker_ethereum/data:/root \
           -p 8545:8545 -p 30303:30303 \
           ethereum/client-go
docker exec -it ethereum-node /bin/sh

我們根據官方的文檔 創建 genesis.json文件裏面寫入

{
  "config": {
        "chainId": 12,  //這裏不能爲0，否則轉賬時報錯
        "homesteadBlock": 0,
        "eip155Block": 0,
        "eip158Block": 0
    },
  "alloc"      : {},
  "coinbase"   : "0x0000000000000000000000000000000000000000",
