MQTT real-time support for MESHdesk and APdesk

• Install the Mosquitto MQTT broker according to these detailed instructions:
  • https://www.vultr.com/docs/install-mosquitto-mqtt-broker-on-ubuntu-20-04-server/
• Make sure you perform step 3 to secure the application with username and password.
• In this document we use the username and password of openwrt, please change them according to your needs.

• The Rdcore API Gateway is a Node.js application. We start with the installation of Node.js and npm.

sudo apt install nodejs
sudo apt install npm

• Change to the /opt directory

cd /opt

• Clone Rdcore API Gateway from Github

sudo git clone https://github.com/RADIUSdesk/Rdcore-API-Gateway.git

• Change to the newly cloned directory

cd /opt/Rdcore-API-Gateway

• Install NPM dependencies

sudo npm install

• Rename .env.sample to .env and edit

sudo mv .env.sample .env
sudo vi .env
 
PORT=8001
#FQDN of your installed server
MESH_CONTROLLER="http://cloud.mesh-manager.com"
MQTT_BROKER="127.0.0.1"
MQTT_PORT=1883
MQTT_USER=openwrt
MQTT_PASS=openwrt

• The Rdcore API gateway systemd startup file

sudo cp /opt/Rdcore-API-Gateway/rdcore-api-gateway.service /lib/systemd/system/

• Activate the Rdcore API Gateway

sudo systemctl enable rdcore-api-gateway.service

• Start the Rdcore API gateway

sudo systemctl start rdcore-api-gateway.service
sudo systemctl status rdcore-api-gateway.service

• Confirm that the service is running by calling the FQDN:8001
• e.g http://cloud.radiusdesk.com:8001/

• To activate MQTT on RADIUSdesk, you must configure it in two places.
• For the devices managed by MESHdesk and APdesk there is this GUI under Settings → MQTT

• Command topic is always /RD/NODE/COMMAND/RESPONSE
• To enable the server to use MQTT instead of the heartbeat system, you must edit the following configuration file.
• Edit /var/www/html/cake4/rd_cake/config/MESHdesk.php
• Search for these sections and adapt them to the values of your server.

$config['mqtt_settings']['enable_realtime']	= true;
$config['mqtt_settings']['api_gateway_url']	= 'http://164.160.89.129:8001';
