我的環境： VirtualBox Ubuntu
1. 此過程是以Docker為基礎操作的, 所以首先需要安裝Docker。
可參考：https://www.cnblogs.com/shuaixiha/p/9923041.html
2. 下載以太坊的鏡像
docker pull ethereum/client-go
3. 創建文件夾
mkdir ethereum_node
cd ethereum_node
vi start-node.sh
文件start-node.sh的內容如下：
#!/bin/bash -e
docker rm -f eth_node || true
NETWORKID=12345
DATADIR=/home/vagrant/ethereum_node/chain
mkdir -p $DATADIR
docker run -it --name eth_node -v $DATADIR:/root/.ethereum -p 8545:8545 -p 30303:30303 ethereum/client-go --networkid $NETWORKID --ws --rpc --rpcaddr 0.0.0.0 --rpccorsdomain '*' --rpcapi "db,eth,net,web3,personal" --wsapi "personal,web3" console
4. 執行shell文件start-node.sh ( 如執行文件沒有權限需 chmod 777 start-node.sh )

Welcome to the Geth JavaScript console!
instance: Geth/v1.8.11-unstable-c8dcb958/linux-amd64/go1.10.2
modules: admin:1.0 debug:1.0 eth:1.0 miner:1.0 net:1.0 personal:1.0 rpc:1.0 txpool:1.0 web3:1.0
> > eth.accounts
[]
5. 此時節點中沒有賬戶, 需創建賬戶如下:
// 表示創建的賬戶密碼為空
> personal.newAccount("")
"0xa60c18c6c8219d5ce26274d32cd03f4ddcd6df4a"
6. 查看所有的賬戶
> eth.accounts
["0xa60c18c6c8219d5ce26274d32cd03f4ddcd6df4a"]
或者
> personal.listAccounts
["0xa60c18c6c8219d5ce26274d32cd03f4ddcd6df4a"]
7. 查詢賬戶余額
eth.getBalance(eth.accounts[0])
或者
web3.fromWei(eth.getBalance(eth.accounts[0]), "ether")
8. 開始挖礦
miner.start()
9. 停止挖礦
miner.stop()
10. 當賬戶有余額的時候可進行交易
personal.unlockAccount("0x21cb7cb49d4fe1c7afde2a60690219c3dad0b357", "") // 交易之前需先解鎖賬戶, 否則交易會報錯
> eth.sendTransaction( {from: 發起交易賬戶地址, to: 接收賬戶地址, value: 貨幣數量} )
例：
eth.sendTransaction({from: '0x21cb7cb49d4fe1c7afde2a60690219c3dad0b357', to: '0x90380f68612fee4288699b41daf6a81fbb9b5972', value: web3.toWei(1, "ether")})
