HPB Private Chain Building Guide

It is very convenient and cost-effective to build a local test chain if you want to develop DAPP. Direct deployment to the main chain consumes tokens and causes a lot of inconvenience. The following are detailed instructions to build HPB test chain.

Test chain local building steps

The following table shows the complete steps to locally build the test chain.

No	Step	Content	Note
1	Determine program execution path	Determine program execution path	Command：`sudo mkdir /home/ghpb-bin2` Note:/home/ghpb-bin2 can be replaced as the specified path

Test chain local building example

(1) Determine program execution path

Input sudo mkdir /home/ghpb-bin2 to create the program execution path, in which /home/ghpb-bin2 can be replaced as the specified path.

hpb@ dell-PowerEdge-R730:~$ sudo mkdir /home/ghpb-bin2

(2) Switch to ROOT user

Inputsu root, ROOT account password as prompted.

hpb@ dell-PowerEdge-R730:~$ su root
Password:

(3) Choose download path

Input cd /home/ in which /home/ can be replaced as the specified path.

root@ dell-PowerEdge-R730: ~$ cd /home/

(4) Download go-hpb source code

Input sudo git clone -b version_x.xxx https://github.com/hpb-project/go-hpb when the progress becomes 100%. If "checking conectivity ... done" appears, it shows go-hpb is successfully downloaded, please continue the next step; (xxxx is the latest version number of the main network program)

root@dell-PowerEdge-R730:/home# sudo git clone -b version_1.0.1.0 https://github.com/hpb-project/go-hpb
Cloning into 'go-hpb'...

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.

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>

(5)go-hpb Compile go-hpb

Input cd go-hpb/

Continue to input make all to compile go-hpb

root@ dell-PowerEdge-R730:/home# cd go-hpb/
root@ dell-PowerEdge-R730:/home/go-hpb# make all
build/env.sh go run build/ci.go install ./cmd/ghpb
>>> /usr/lib/go-1.9/bin/go install -ldflags -X main.gitCommit=04fa6c874b447f0de0a4296b9e573119e1997fcc -v ./cmd/ghpb
github.com/hpb-project/go-hpb/vendor/github.com/prometheus/procfs/internal/util
github.com/hpb-project/go-hpb/common/bitutil
……
Done building.
Run "/home/go-hpb/build/bin/promfile" to launch promfile.

(6) Copy program to execution path

Input sudo cp build/bin/. /home/ghpb-bin2/; continue typing cd /home/ghpb-bin2/. Where /home/ghpb-bin2/ is the program execution path set for you;

root@ dell-PowerEdge-R730:/home/go-hpb# sudo cp build/bin/* /home/ghpb-bin2/
root@ dell-PowerEdge-R730:/home/go-hpb#cd /home/ghpb-bin2/

(7) Create three accounts

Input ./ghpb --datadir node/data account new to create first new account, set account password as prompted and record account address "04cbf60fdcc485a76b0b8a389da7bd87da180edd".

Record the hnode information and add public network ip in front of the port number (public network Ip is the public network ip address of the server where the bootnode is located. It is 192.168.1.50 in the example and the developer needs to change to its own public network Ip):

hnode://ad65b8d7efc85c50b13f63a0a7234d1398136a200dbe104ff759daf7912fe7ce2c996db38135883599e0802f24849c2e1e5ee4502d401e6b39823552dba331a9@192.168.1.50:3001

(11) Open configuration file

Input exit to exit, contiute to input vi /home/go-hpb/config/networkconfig.go to open configuration file

(12) Write hnode into configuration file

Find the var MainnetBootnodes method in the open file, input hnode information (including public network ip) in this method; and input // before the rest of the hnode information, showing that unnecessary hnode information is commented out.

Note: Move the cursor to the first line in the method, press letter o and it automatically insert an empty line, then you can paste hnode information, pay attention to the double quotes and commas since the format is in English.

var MainnetBootnodes = []string{
        //"hnode://73c8ac9dddc8f094d28f42e1ec5c3e8000cad25be152c147fceacc27953d58e64bfe9f555145d93f9f6b995bab984411941751fef3bd460f74c0151eb0432b56@47.94.20.30:30303",

(13) Save configuration file

Press Esc， type :wq and press Enter to save. Note: If you want to quit without saving the file, press Esc, input: q! and press Enter; if you can't edit, press the letter i.

:wq

(14) Compile source code

Input cd /home/go-hpb/, in which /home/ is the download path for go-hpb; continue to type make all to compile.
