Install the Discovery Module - Linux - Configuring the Services (with systemctl)

If your OS provides access to systemctl, follow these instructions. We want the Discovery services (daemons) to run as their own user. To do this:

1. Create a new User and Group named "Discovery", as follows:
   

sudo groupadd Discovery

sudo useradd -M -s /bin/nologin -g Discovery -d /opt/Discovery Discovery

2. Then change the owner of the Discovery directory to the new "Discovery" user:
   

sudo chown Discovery:Discovery /opt/Discovery -R

3. If you look in Discovery's "bin" directory (/opt/Discovery/platform/bin) you'll see two scripts: logiDataService.sh and logiApplicationService.sh. Both of these scripts need to be run to start the full Discovery server. In this next section, we'll configure a service to start and stop the Discovery server.
   
   First, we'll configure the application service:
   

sudo nano /etc/systemd/system/LogiApplicationService.service


Include these items in the LogiApplicationService.service file:




Next, for the data service:


sudo nano /etc/systemd/system/LogiDataService.service


Include these items in the LogiDataService.service file:

4. Finally, run this command so systemd picks up the changes:
   
   

sudo systemctl daemon-reload


And then start the services:

sudo service LogiDataService start
sudo service LogiApplicationService start

Now run this test to see if the server responds:

curl localhost:3000

If you receive a message that says "Cannot GET /" then the installation was successful. Congratulations!

Start Services on Boot

If you'd like to have both services start on boot, do this:

sudo systemctl LogiApplicationService enable
sudo systemctl LogiDataService enable
