I've bootstrapped this project in order to have a standalone IoT gateway. My intention is to use it as an educational tool to support exercises. Therefore, there is no security and user management is reduced to the minimum.
- MQTT (Mosquitto)
- Data broker (Node-RED)
- Time series storage (InfluxDB)
- Visualisation (Grafana)
- Reverse proxy (nginx)
- TCP/80: HTTP
http://<gateway>/red: Node-RED editorhttp://<gateway>/red/ui: Node-RED dashboardhttp://<gateway>/grafana: Grafana
- TCP/1883: MQTT
- TCP/8086: InfluxDB HTTP API
Where <gateway> should be replaced by the IP address of the gateway.
A training user can be created or removed thanks to some scripts
create-user.PS1remove-user.PS1
The following script do the same for users training1..training12
create-training-user-set.PS1remove-training-user-set.PS1
The Node-RED instance is shared among all users. Pay attention not to mess with someone else's flows.
Suggestion: prefix your MQTT topics name with your username
<username>-<flow-name>
Node-RED documentation: https://nodered.org/docs/.
Each user will have its own Grafana Organization named after his/her username.
Grafana documentation: http://docs.grafana.org/.
The Mosquitto instance is shared among all users. Pay attention not to mess with someone else's topics.
Suggestion: prefix your MQTT topics name with your username
<username>/+/+/+
Mosquitto documentation: https://mosquitto.org/.
There is no authentication on this InfluxDB instance. The user creation script will only create a database with the username.
InfluxDB documentation: https://docs.influxdata.com/.
The nginx server runs on port 80 and forwards the following URLs:
http://<gateway>/red: Node-RED editorhttp://<gateway>/grafana: Grafana
It also provides a home page with the previous links.
Nginx documentation: https://nginx.org/en/docs/.
