HPB63：HPB私有链搭建指南

如果想进行DAPP 开发，那么在本地搭建一个测试链是非常方便划算的！直接部署到主链将会消耗代币以及很多不便，下面是搭建HPB测试链的详细步骤！

测试链本地搭建步骤

下表为完整的本地搭建测试链步骤。

编号 步骤 内容 说明
1 确定程序执行路径 确定程序执行路径 命令：sudo mkdir /home/ghpb-bin2
提示：/home/ghpb-bin2可改为指定路径。 |
2 切换成ROOT用户 切换成ROOT用户 命令：su root
根据提示输入ROOT账户密码 |
3 选择下载路径 选择下载路径 命令：cd /home/
提示：/home/可改为指定路径； |
4 下载go-hpb源码 下载go-hpb源码 命令：sudo git clone -b version_x.x.x.x https://github.com/hpb-project/go-hpb

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:

  git checkout -b <new-branch-name>

  • 配置binding.json

    输入vim binding.json将所有账户写入binding.json，

    “`shell root@hpb-PowerEdge-R730xd:/home/ghpb-bin2# vim binding.json

    “`

    在打开的文件中按下I变为Insert可输入状态，并粘贴以下代码：

    (用户需将三个coinbase更改为三个新建账户的地址，CID和HID可随意填写，可与示例中的保持一致。)

    “`shell [ {“coinbase”:“0xfc6661501b4faf424d2ed61855a134fa5b2de3ef”,“cid”:“2cd504a93518fe0c9b60895602586efc4786cf9da9396d0a6d39403b94710b0a16092dcbd8458bb46cef1e71ba9953db881268ce5d773ce63ffb421a657a00e1”,“hid”:“a3b8e1f3bd9cf3ed0a520744010bf2cc48e781b04af7f462e452f9c96e476abc”}, {“coinbase”:“0xaf4a70602be17074ad59555fa09239c0d811a99f”,“cid”:“2cd504a93518fe0c9b60895602586efc4786cf9da9396d0a6d39403b94710b0a16092dcbd8458bb46cef1e71ba9953db881268ce5d773ce63ffb421a657a00e1”,“hid”:“a3b8e1f3bd9cf3ed0a520744010bf2cc48e781b04af7f462e452f9c96e476abc”}, {“coinbase”:“0x552a49773698c75b7fbb47f1a3486f6394cc4385”,“cid”:“2cd504a93518fe0c9b60895602586efc4786cf9da9396d0a6d39403b94710b0a16092dcbd8458bb46cef1e71ba9953db881268ce5d773ce63ffb421a657a00e1”,“hid”:“a3b8e1f3bd9cf3ed0a520744010bf2cc48e781b04af7f462e452f9c96e476abc”} ]

    “`

    按下Esc键并输入:wq即可保存文件并退出。

  • 拷贝binding.json

    输入cp binding.json node1/data拷贝binding.json到bootnode数据文件里。

    “`shell root@hpb-PowerEdge-R730xd:/home/ghpb-bin2# cp binding.json node1/data

    “`

  • 启动bootnode

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）

(12)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。
