Port settings not working from systemd?

[ctowen]

Unfortunately, our system already has services running on port 8000 and 8001 so I set out to change the ports that the lora-server and api run on, but it doesn't work when running from systemd.

When I start the loraserver with the following command, everything works as expected and the service starts on the specified port:

/opt/loraserver/bin/loraserver --net-id "010203" --band "EU_863_870" --bind "127.0.0.1:5560" --redis-url "redis://localhost:6379" --as-server "127.0.0.1:5561" &

However when I start the loraserver as a service as described in your instructions using systemd and systemctl, It tries to find the app-server on port 8001. Is it possible there is a bug and it isn't wired correctly in the code to use the port from the configuration file when launching as a service? Or can you check my settings to make sure they are correct?

I based them off the documentation here: https://docs.loraserver.io/loraserver/getting-started/

[Service] Environment="NET_ID=010201" Environment="BAND=EU_863_870" Environment="BIND=127.0.0.1:5560" Environment="REDIS_URL=redis://localhost:6379" Environment="GW_MQTT_SERVER=tcp://localhost:1883" Environment="AS_SERVER=127.0.0.1:5561"

Please note that the components don't read the config file, the config file is used by systemd to expose the config through environment variables.

You could also test these settings by starting loraserver like this:

NET_ID=010201 BAND=EU_863_870 /opt/loraserver/bin/loraserver

If that works with, it means that the config is not correctly loaded (or refreshed) by systemd.

Thank you - that makes sense.

I still think there is an issue though. I don't believe it is getting the port from the env variable. See below:

Ah you're right. I see there is a typo in the env variable config. This has been fixed in the master branch and will be included in the next release. For now, use one of these pre-compiled binaries I made for you: https://www.dropbox.com/sh/nawdaw666ls04y8/AABqCPqNrA4rET8txvLzEcwra?dl=0
