Project Introduction

With over 20 years of experience in embedded R&D, production, and IoT platform construction, we have launched this open-source hardware device based on extensive customer feedback.

It is crucial to quickly validate concepts when starting a new project. Therefore, we have integrated as many core components as possible into one product, including various sensors, networking modules, and multiple power supply methods. We also provide functions such as online programming and flashing, helping customers rapidly verify their ideas at the lowest cost.

In addition, this project provides a rich set of features and services for the corresponding IoT platform.

Installation Guide

It is recommended to perform the following operations on an Ubuntu system with administrator privileges (sudo).

Prepare Environment

sudo apt update && sudo apt upgrade -y
mkdir -p /opt/dc01

Install MongoDB

cd /opt/dc01
wget https://repo.mongodb.org/apt/ubuntu/dists/jammy/mongodb-org/8.0/multiverse/binary-amd64/mongodb-org-server_8.0.3_amd64.deb
sudo dpkg -i mongodb-org-server_8.0.3_amd64.deb

sudo mkdir -p /opt/mongodb-8.0.3/{data,logs} && touch /opt/mongodb-8.0.3/logs/mongodb.log

Edit Configuration File

vi /etc/mongod.conf

Modify the following fields:

dbPath: /opt/mongodb-8.0.3/data
path: /opt/mongodb-8.0.3/logs/mongodb.log
bindIp: 0.0.0.0 # Set to 0.0.0.0 if external access is required

Set Directory Permissions

sudo chown -R mongodb:mongodb /opt/mongodb-8.0.3/data
sudo chown -R mongodb:mongodb /opt/mongodb-8.0.3/logs
sudo chmod -R 755 /opt/mongodb-8.0.3/data

Start in Standalone Mode

mongod --port 27017 --dbpath /opt/mongodb-8.0.3/data --noauth

Set Root Password

mongosh
use admin
db.createUser({
  user: "root",
  pwd: "mongoDBTest1password",  
  roles: [
    { role: "root", db: "admin" }
  ]
})
exit
ctrl+c

Set Directory Permissions Again

sudo chown -R mongodb:mongodb /opt/mongodb-8.0.3/data
sudo chown -R mongodb:mongodb /opt/mongodb-8.0.3/logs
sudo chmod -R 755 /opt/mongodb-8.0.3/data

Enable Auto-start on Boot

sudo systemctl enable mongod

Start MongoDB Service

sudo systemctl start mongod
