安裝docker

Mac參考https://blog.csdn.net/jiang_xinxing/article/details/58025417

1.2Docker命令

docker --version
docker-compose --version
docker-machine --version
docker ps  檢視web伺服器容器的詳細資訊
docker run hello-world 測試安裝的docker是否正常
docker run -d -p 80:80 --name webserver nginx 執行nginx，然後訪問localhost

nginx web伺服器在你停止或者移除容器之前會持續執行著

docker start webserver  啟動伺服器
docker stop webserver  停止web伺服器
docker ps -a  檢視終止狀態的容器
docker rm -f webserver 移除正在執行的容器
docker list 列出本地映象
docker rmi後加ID號和映象名字 如：docker rmi ngix  移除一個長期不需要的映象

啟動docker

service docker start

pull初鏈映象

docker pull registry.cn-hangzhou.aliyuncs.com/truechain_space/truechain_image:latest
 

更改映象tag為etrue

docker tag registry.cn-hangzhou.aliyuncs.com/truechain_space/truechain_image etrue

建立genesis.json檔案

1.建立truechain目錄 mkdir truechain 2.進入目錄 cd truechain 3.建立genesis.json檔案 touch genesis.json sudo vi genesis.json 檔案內容是：

簡單介紹一下這個genesis.json

chainId 鏈的ID alloc 系統自帶的兩個地址及餘額 coinbase 礦工工號 difficulty 挖礦難度 extraData 擴充套件欄位 gasLimit 交易手續費 nonce 隨機字串，用於挖礦 mixhash 配合nonce進行挖礦 parentHash 上一個區塊的雜湊 timestamp 區塊生成的時間

建立創世區塊

1.在truechain目錄下執行下面命令

docker run -v $PWD:/truechain-engineering-code -v $PWD/data:/truechain-engineering-code/data -it etrue  --datadir /truechain-engineering-code/data init /truechain-engineering-code/genesis.json

啟動節點

docker attach ba86d98b919b 1.進入truechain目錄下，啟動單節點測試網路

docker run -v $PWD:/truechain-engineering-code -it etrue --singlenode --datadir /truechain-engineering-code/data --bftkeyhex "c1581e25937d9ab91421a3e1a2667c85b0397c75a195e643109938e987acecfc" --election --bftip "172.21.0.5" --bftport 10080 --port 30303 --networkid 10 --rpc --rpcaddr 127.0.0.1 --rpcport 8545 --rpcapi "db,etrue,net,web3,personal,admin,miner" --verbosity 1 console

2.解析命令

1）-singlenode --bftkeyhex “xxx” 單節點啟動網路，引數是節點私鑰，該私鑰和genesis檔案裡的公鑰是一對. 2）–election --bftip “172.26.246.28” --bftport 10080 本節點參與委員會選舉，配置自己的ip和埠。但單節點執行環境，本身就是委員會節點，所以這條命令可以不用。

使用測試網路

3.建立賬戶：personal.newAccount() publickey=04044308742b61976de7344edb8662d6d10be1c477dd46e8e4c433c1288442a79183480894107299ff7b0706490f1fb9c9b7c9e62ae62d57bd84a1e469460d8ac1 ip=172.21.0.5

0x9869b72d3a27b438b5d7f56d959f581c3ca69082 0x1f726f9b4d8324c2a39858136d3019239cb4e1fb

1.查詢賬戶： etrue.accounts

2.查詢賬戶餘額： etrue.getBalance(“0x1f726f9b4d8324c2a39858136d3019239cb4e1fb”) etrue.getBalance(“0x9869b72d3a27b438b5d7f56d959f581c3ca69082”)

4.轉賬數額位和true單位轉換：amount = web3.toWei(5000,‘ether’)

5.賬戶解鎖：personal.unlockAccount(etrue.accounts[0])或 personal.unlockAccount(“0x1f726f9b4d8324c2a39858136d3019239cb4e1fb”)

6.轉賬交易：etrue.sendTransaction({from:“0x9869b72d3a27b438b5d7f56d959f581c3ca69082”,to:“0x1f726f9b4d8324c2a39858136d3019239cb4e1fb”,value:1})

7.查詢挖礦的coinbase地址：etrue.coinbase

8.啟動挖礦，括號內可以新增數字，表示開啟幾個執行緒：miner.start()

9.停止挖礦：miner.stop()

10.etrue.getTransactionReceipt(“0xf659bf31ee2cc57a0a68417b284c11d0ba23d2376dc236c49af6e8164f04781e”)
