1，摘要
本文详细讲解如何在Ubuntu 64位虚拟机上搭建HPB开发环境，并给出了遇到的各种问题的解决方法。主要包括：
（1）下载HPB版本并编译；
（2）创建账号和创始区块
（3）获取本地hnode信息并重新编译版本
（4）开启启动节点(bootnode)和高性能节点(挖矿)
（5）进入本地开发环境
总体分析来看，HPB由于采用BOE硬件导致存在多类节点，本地环境的编译也比较复杂。环境搭建成功后，就可以享受HPB类以太坊环境但具备高TPS性能的优势了。
2，操作内容
2.1 前置环境搭建
本文有个前置条件，开发者需要已经具备了安装了GO环境的Ubuntu 64位系统或者虚拟机。没有的环境的WINDOWS用户，可参考铂链第1课 如何在WINDOWS操作系统下搭建BOTTOS开发环境完成前置 环境的搭建。也可以在阿里云申请虚拟机或者ECS，选择Ubuntu 64位操作系统。
2.2 下载HPB版本并第一次编译
1） 建立HPB工程工作目录
【成功结果输出】
duncanwang@ubuntu64bit-server:~$ mkdir hpb
duncanwang@ubuntu64bit-server:~$ cd hpb
duncanwang@ubuntu64bit-server:~/hpb$ mkdir ghpb-bin
2）下载go-hpb源码
在芯链GITHUB主页上(https://github.com/hpb-project/go-hpb/releases)，可以找到最新的稳定版本，下载适合的版本。例如，辉哥下载的最新稳定版本为"version_1.0.3.1"。
git clone -b version_x.x.x.x https://github.com/hpb-project/go-hpb
【提示】x.x.x.x为主网程序最新版本号
【说明】下载官网的BIN程序，连的的主网。搭私链，要改源码的bootnode信息，所以必须本地编译HPB版本。
【成功输出结果】
duncanwang@ubuntu64bit-server:~/hpb$ git clone -b version_1.0.3.1 https://github.com/hpb-project/go-hpb

do so (now or later) by using -b with the checkout command again. Example:
git checkout -b <new-branch-name>

【结果】
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ ./promfile
+-----------------------------------------------------------+
| Welcome to prometh, your HPB private network manager |
| |
| This tool lets you create a new HPB network down to |
| the genesis block, bootnodes, miners and ethstats servers |
| without the hassle that it would normally entail. |
| |
| Prometh uses SSH to dial in to remote servers, and builds |
| its network components out of Docker containers using the |
| docker-compose toolset. |
+-----------------------------------------------------------+
Please specify a network name to administer (no spaces, please)
>
1）给测试链命名，可随意命名
【结果】
> HiBlock
Sweet, you can set this via --network=HiBlock next time!
INFO [12-27|07:25:39] HPB : Administering HPB network name=HiBlock
WARN [12-27|07:25:39] HPB : No previous configurations found path=/home/duncanwang/.prometh/HiBlock
2） 选择1，生成新的创世文件
【结果】
What would you like to do? (default = stats)
1. Configure new genesis
2. Manage existing genesis
> 1
Welcome to HPB consensus engine file maker
3）设置生成区块的间隔，如5
【结果】
How many seconds should blocks take? (default = 15)
> 5
4）设置投票周期，如100
【结果】
How many blocks should voting epoch be ? (default = 30000)
> 100
5）设置初始挖矿地址，示例为新建的第一个账户
可继续添加挖矿地址，按回车可进入下一步
【结果】
Which accounts are allowed to seal? (initialise miner addresses)
> 0x17b164fab6b429cc54913745e71939c029d6b835
> 0x
6）设置初始预存钱的地址
示例为新建的第一个账户0x17b164fab6b429cc54913745e71939c029d6b835
Which accounts should be pre-funded? (advisable at least one)
> 0x17b164fab6b429cc54913745e71939c029d6b835
> 0x
7） 设置网络号，可随意设置，后续启动命令中需用到该网络号
硬件初始化直接回车忽略。
【结果】
Please input the initialization hardware random
> 0x
Specify your chain/network ID if you want an explicit one (default = random)
> 66300
8）在创始块埋个彩蛋
例如土星是土豪的拼音
Anything fun to embed into the genesis block? (max 32 bytes)
> tuxingshituhao
9）导出刚设置的创世文件
What would you like to do? (default = stats)
1. Configure new genesis

按下Esc键并输入:wq即可保存文件并退出。
2）拷贝binding.json
输入cp binding.json node1/data拷贝binding.json到bootnode数据文件里。
cp binding.json node1/data
【结果】
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ cp binding.json node/data
3）启动bootnode获得hnode信息
输入./ghpb --datadir node1/data --networkid 66300 --port 3001 --nodetype bootnode console（66300为创建创世区块过程中设置的网络号，3001为端口号，不同节点不同以作区分）
./ghpb --datadir node1/data --networkid 66300 --port 3001 --nodetype bootnode console
【结果】
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ ./ghpb --datadir node1/data --networkid 66300 --port 3001 --nodetype bootnode console

sudo killall -9 ghpb iperf3

2.4 获取本地hnode信息后，重新编译版本
（1）修改配置文件
1）输入exit退出
【结果】
exit
INFO [12-28|08:21:13] HPB : Hpb data sync stopped
INFO [12-28|08:21:13] HPB : IPC endpoint closed endpoint=/home/duncanwang/hpb/ghpb-bin/node1/data/ghpb.ipc
INFO [12-28|08:21:13] HPB : Database closed database=/home/duncanwang/hpb/ghpb-bin/node1/data/ghpb/chaindata
2）继续输入vi /home/go-hpb/config/networkconfig.go打开配置文件；
【结果】
exit
INFO [12-27|09:06:04] HPB : Hpb data sync stopped
INFO [12-27|09:06:04] HPB : IPC endpoint closed endpoint=/home/duncanwang/hpb/ghpb-bin/node/data/ghpb.ipc
INFO [12-27|09:06:04] HPB : Database closed database=/home/duncanwang/hpb/ghpb-bin/node/data/ghpb/chaindata
3）将hnode写入配置文件
在打开的文件中找到var MainnetBootnodes方法，在该方法中输入hnode信息（含公网ip）；并在其余hnode信息前都输入//，表示注释掉不需要的hnode信息。
提示：将光标移到方法里的第一行，按下字母o，即自动插入空的一行，此时即可粘贴hnode信息，注意带上双引号和逗号，格式为英文。
var MainnetBootnodes = []string{
"hnode://3be2d632c0ff1e143a7e397750da9be03e82d6eed4dd6f23642a6f42d5a18ad735c1dc7358892c538d33143311a8cc42737dd4f62ef1d5a1e88e670539cc705c@10.225.17.8:3001",
//"hnode://73c8ac9dddc8f094d28f42e1ec5c3e8000cad25be152c147fceacc27953d58e64bfe9f555145d93f9f6b995bab984411941751fef3bd460f74c0151eb0432b56@47.94.20.30:30303",
//"hnode://a6ef92a46adb69f94f2d48ff20f7800fb057d6aba7945e5af062ef27be5598072c5ce083ec5a2c89f80d112401c261b9ba9dacbd53aeb7c8243685d537edadb9@47.254.133.46:30303",
}
【操作方法】
sudo vi /home/go-hpb/config/networkconfig.go
4)保存配置文件
按下Esc，并输入:wq,回车即可保存。 提示：如果想退出不保存文件，则需按下Esc,并输入:q!回车即可；如果无法编辑， 可按下字母i即可。
:wq
（2）再编译程序
输入go-hpb的下载路径
cd /home/duncanwang/hpb/go-hpb
继续输入make all编译。
【结果】
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ cd /home/duncanwang/hpb/go-hpb
duncanwang@ubuntu64bit-server:~/hpb/go-hpb$ make all

cp "/home/duncanwang/hpb/go-hpb/network/p2p/config.json" "/home/duncanwang/hpb/go-hpb/build/bin/config.json"
2.5 开启启动节点(bootnode)和高性能节点(挖矿)
1）拷贝程序到执行路径ghpb-bin，
该操作会覆盖目标目录的同名文件，其中/home/duncanwang/hpb/ghpb-bin/为您设置的程序执行路径；
【结果】
duncanwang@ubuntu64bit-server:~/hpb/go-hpb$ sudo cp -r build/bin/. /home/duncanwang/hpb/ghpb-bin/
duncanwang@ubuntu64bit-server:~/hpb/go-hpb$ cd /home/duncanwang/hpb/ghpb-bin
2）开启启动节点(bootnode)
输入sudo nohup ./ghpb...启动bootnode; 继续输入attach连入节点。
其中示例里为创建的第二个账户，66300为步骤8中设置的网络号。
sudo nohup ./ghpb --datadir node1/data --networkid 66300 --port 3001 --rpcaddr 0.0.0.0 --rpcport 8541 --verbosity 3 --rpc --rpcapi hpb,web3,admin,txpool,debug,personal,net --nodetype bootnode > bootnode.log &
sudo ./ghpb attach http://127.0.0.1:8541
【结果】
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ sudo nohup ./ghpb --datadir node1/data --networkid 66300 --port 3001 --rpcaddr 0.0.0.0 --rpcport 8541 --verbosity 3 --rpc --rpcapi hpb,web3,admin,txpool,debug,personal,net --nodetype bootnode > bootnode.log &
[1] 5450
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ nohup: ignoring input and redirecting stderr to stdout
sudo ./ghpb attach http://127.0.0.1:8541

2）启动第一个挖矿节点
另开一个控制台窗口输入./ghpb根据提示输入账户密码，启动第一个挖矿节点； 继续输入miner.start()开始挖矿。
示例里为创建的第一个账户"0x17b164fab6b429cc54913745e71939c029d6b835"；
sudo ./ghpb --datadir node/data --unlock "0x17b164fab6b429cc54913745e71939c029d6b835" --networkid 66300 --port 3002 --rpcaddr 0.0.0.0 --rpcport 8542 --verbosity 3 --rpc --rpcapi hpb,web3,admin,txpool,debug,personal,net console --testmode
miner.start()

3.运行结果
2.6 进入本地开发环境
进入挖矿节点环境2
新的窗口输入attach可以进入节点环境，便于进行后续操作事宜。
例如，进入第一个挖矿节点
./ghpb attach http://127.0.0.1:8542
【结果】
duncanwang@ubuntu64bit-server:~/hpb/ghpb-bin$ ./ghpb attach http://127.0.0.1:8542
