GBT-MIS Blockchain

Run

• Quick start

go build -o GBT-MIS
./GBT-MIS

This method is to start 4 blockchain nodes locally

• General form

./GBT-MIS -f <config_file>

You can modify the configuration file according to the actual situation or use the configuration file generation tool under common/config.go to generate a new configuration file. If it fails to run, please check whether the MongoDB database service is enabled. If it is not enabled, you can use the following command to enable it:

sudo service mongod start

If MongoDB has not been installed, please refer to the following webpage to install it:

Installation

1、Set GOMODULE on

go env -w GO111MODULE="on"

2、Update code. After pulling the latest code, Goland will prompt you to detect Go Moudule. You need to click Enabled. Note: The following environment can be filled in or not.

3、Change Go Proxy

go env -w GOPROXY="https://proxy.golang.com.cn"

4、Update go mod

go mod tidy

Instructions for use

By default (quick start), four blockchain nodes are running locally, with an IP address of 127.0.0.1, blockchain communication ports 5010, 5011, 5012, 5013, and service ports 8010, 8011, 8012, 8013 for the management front-end. The connection establishment ports provided for vpn-management-server are 9999, 10000, 10001, 10002, and the ports for normal communication are 6666, 6667, 6668, 6669.
