运用docker镜像搭建TrueChain测试私有环境

安装docker

ubuntu参考https://blog.csdn.net/bingzhongdehuoyan/article/details/79411479
Mac参考https://blog.csdn.net/jiang_xinxing/article/details/58025417
Windows参考http://www.runoob.com/docker/windows-docker-install.html

启动docker

service docker start

pull初链镜像

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

更改镜像tag为etrue

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

创建genesis.json文件

1.创建truechain目录
mkdir truechain
2.进入目录
cd truechain
3.创建genesis.json文件
touch genesis.json
sudo vi genesis.json
文件内容是：

"config": {
   "chainId": 10,
   "homesteadBlock": 0,
   "eip155Block": 0,
   "eip158Block": 0

简单介绍一下这个genesis.json

chainId 链的ID alloc 系统自带的两个地址及余额 coinbase 矿工工号 difficulty 挖矿难度 extraData 扩展字段 gasLimit 交易手续费 nonce 随机字符串，用于挖矿 mixhash 配合nonce进行挖矿 parentHash 上一个区块的哈希 timestamp 区块生成的时间

创建创世区块

1.在truechain目录下执行下面命令

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

启动节点

1.进入truechain目录下，启动单节点测试网络

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" console

2.解析命令

1）-singlenode --bftkeyhex "xxx" 单节点启动网络，参数是节点私钥，该私钥和genesis文件里的公钥是一对. 2）--election --bftip "172.26.246.28" --bftport 10080 本节点参与委员会选举，配置自己的ip和端口。但单节点运行环境，本身就是委员会节点，所以这条命令可以不用。

使用测试网络

1.查询账户：etrue.accounts

2.查询账户余额：etrue.getBalance("账户地址")

3.创建账户：personal.newAccount()

4.转账数额位和true单位转换：amount = web3.toWei(5000,'ether')

5.账户解锁：personal.unlockAccount(etrue.accounts[0])或 personal.unlockAccount(“账户地址”)

6.转账交易：etrue.sendTransaction({from:"xxx",to:"xxx",value:amount})

7.查询挖矿的coinbase地址：etrue.coinbase

8.启动挖矿，括号内可以添加数字，表示开启几个线程：miner.start()

9.停止挖矿：miner.stop()

10.etrue.getTransactionReceipt("xxx")
